Description of related art:
among the five traditional senses, the sense of smell is most strongly related to memory. We have a poor accuracy in recalling what we see a month ago, while we have a very accurate recall of what we smell a year ago. This phenomenon is attributed to the close relationship between the olfactory bulb and the limbic system of the brain (often referred to as the "emotional brain").
It is recognized that: the sense of smell is the most emotional expression of the five senses, and is the most valuable element for brand transmission and experiential marketing. Put another way, olfaction is very effective in delivering the complete multi-sensory environment, as it is the most effective sense of forming a lasting impression.
Lead enterprises in the industry areas like restaurants, retail, gaming, real estate, healthcare, and advanced living (sensor living) recognize the power of "scent marketing" and are seeking service solutions for their effective, safe, and easy-to-use businesses. However, the wide area spread of accurate, consistent, and measurable fragrances has become a significant challenge for early service providers in this emerging market. Their odor solutions provide an experience that varies widely as the quality of the odor impression degrades over time and varies widely in varying environments.
Some current scent dispersal technologies provide independent solutions that are managed locally by field personnel or local subcontractors. As the scent dispensed by these commercial scent devices is manually set and often changes over time, ensuring a consistent scent level within brand standards across all locations is extremely difficult. Common odor dispersion problems include unexplained dispenser malfunction, incorrect dispenser settings and device intervention, and the "blindness" of the odor that occurs when employees working in a scented location become insensitive to fragrance, causing them to make unwanted changes to manual settings.
Given the large variability of conditions across local sites, it is very difficult to accurately predict the replacement date of a scent "refill cartridge" (an element often used in dispensing systems to contain a scent oil or other fragrance source). Therefore, when the cartridge is lighted, there are many places where no fragrance is spread; while other venues experience wasted scented oil, increased expense, and disposal problems when the cartridge is replaced prematurely.
Thus, current scent solutions employed in multi-site commercial enterprises make it difficult for enterprise brands to build and maintain consistent "acceptable" or "approved" scent concentrations across their site for local site managers and maintenance personnel. Their inability to adequately control the olfactory portion of brand recognition is a constant source of frustration, as field surveys indicate that the vast majority of venues on any given day do not deliver the target sensory experience of the brand.
There remains a need for an odor management system that provides a wide area spread of fragrance in a manner that is consistent, accurate, and controllable over a remote or local network according to a desired scent profile.
Background
Disclosure of Invention
The present disclosure addresses these local "compliance" and brand management issues by enabling, among other things, effective centralized management of remotely deployed scent systems, including but not limited to the use of microprocessor-controlled and networked diffusion devices that deliver data streams to a centralized network operations center (or NOC) that may be equipped with experienced operators using enterprise-level software. With this managed service, and with the help of accurate local tools and enabling components, a commercial profit enterprise can ensure accurate, broad area scent delivery consistent with brand labeling over time and across multiple locations. A wide range of enabling components and techniques are disclosed herein for such an odour management system.
In one embodiment, there may be electrical contacts that need to be between the package and the device when the package is installed. The electrical features on the package may contact the electrical features on the device. If contact is made, the package contents may be dispensed. If no contact is made, the package contents may not be dispensed and an alert may be sent over the network.
In one aspect, a scent cartridge for a networked scent diffusion device can comprise: a reservoir containing a liquid and an atomizer head assembly; and a tamper-proof identifier associated with at least one of the reservoir and the atomizer head assembly, wherein diffusion of the scent from the device is based on a state of the tamper-proof identifier. If the scent diffusion apparatus does not recognize the tamper-proof identifier, an alert may be sent over the network and no scent may be dispensed. If the cartridge is removed from the device, resulting in the device no longer recognizing the tamper-proof identifier, an alert is sent over the network. The state of the anti-tampering identifier changes based on the proximity of the networked diffusion device to the designated network region. In some embodiments, the atomizer head assembly includes an orifice plate including a restrictive orifice for delivering compressed gas to be mixed with the liquid prior to passing through the atomization orifice. The tamper-resistant identifier may be mechanical, such as a dial switch or the like. The tamper-proof identifier may be electronic, such as RFID, barcode/QSR code, NFC ID, and the like. The tamper-proof identifier may be a detachment from a network zone of a networked scent diffusion device, a WiFi zone, or a cellular telephone network. The tamper-proof identifier may be an error in or an unexpected reading of a level sensor of the networked scent diffusion device. The tamper-proof identifier may be a disconnection of electrical contacts provided on at least one of the reservoir and the atomizer head assembly from the networked scent diffusion device. The tamper-proof identifier may be an RFID tag or an NFC ID associated with at least one of the reservoir and the atomizer head assembly. The atomizer head assembly may include an orifice plate including a restrictive orifice for delivering compressed gas to be mixed with the liquid prior to passing through the atomizing orifice. The tamper-resistant identifier may be a mechanical feature of at least one of the reservoir and the atomizer head assembly.

In one aspect, a package for use with an odor diffusing device may include: a reservoir containing a liquid and an atomizer head assembly, wherein the reservoir is joined to the atomizer head assembly at a top edge of the reservoir; and a tube for delivering the liquid in the reservoir, wherein the tube is joined on a first end to the atomizer head assembly and a second end of the tube extends below the surface of the liquid. The gas inlet passage of the atomizer head assembly may have one end in fluid communication with a source of compressed air and a second end of the gas inlet passage in fluid communication with an orifice plate including a flow-restricting orifice. The mixing chamber and the gas entry passageway of the atomizer head assembly may be separated by an orifice plate, the mixing chamber having a first wall opposite the orifice plate including an atomizing orifice and a second wall including an opening in fluid communication with the tube. The expansion chamber may be in fluid communication with the atomization orifice and an anechoic chamber having an outlet to ambient. Gas flowing into the gas inlet passageway through the restrictor orifice creates a region of relatively low pressure in the mixing chamber which causes liquid from the reservoir to be drawn through the tube into the mixing chamber where it joins the flow path of the gas out of the restrictor orifice, thereby creating a gas and liquid mixture which is then atomised as it passes through the atomising orifice. The liquid reservoir may have a substantially cup-shaped geometry. The top edge of the reservoir may be joined to the atomizer head assembly by one of an ultrasonic weld and/or a twist lock with an o-ring seal.
In one aspect, the atomizing diffuser can include a floating magnet disposed within a track inside at least one package for the diffuser having a liquid, wherein the floating magnet moves substantially vertically along the track as a liquid level within the package changes.

Detailed Description
In one aspect, a scent management system provides a managed service to enterprises for accurate, wide area scent delivery that involves impressive brand impressions and unusual customer experiences using scent delivery. By adding intelligence to devices deployed on customer premises and by managing the devices using a global network and a centralized set of software applications, the scent management system provides unprecedented quality and control of remotely managed scent services for customers and ensures that the scent management services are validated, reliable, and consistent. Such an odour management system is able to ensure a level of quality defined based on intelligence added to the system (from the diffuser devices to a central managed Network Operations Centre (NOC)) which monitors device performance across all customers and across all devices of each customer. The scent management system is able to deliver identical scent impressions across all locations, if so desired, through measured scent output and in-space metering of precise concentrations. The scent management system provides a managed scent service that delivers consistent brand impressions by precisely and dynamically controlling a scent diffusion device network, either remotely or locally. Features of the scent management system that couple with features of the networked scent diffusion device, such as bi-directional communication with the device to receive data from the device and remotely control the device, including sensors and/or programming to switch between installed fragrance packages, enable the scent management system to be deployed as part of a variety of service offerings, including self-service operational models and full-service operational models. In the self-service model, a user may select settings of the device and receive an indication of refill, such as through a customer application. In a full service model, the NOC may select and modify settings not just for one location, but across as many locations as needed to meet brand management goals, refill alerts may go to the NOC, which is then responsible for managing refills, and so on. Communicating with the NOC allows a user to trust that devices in a space are operating as desired without having to personally operate the devices or process control applications for the devices. Of course, the flexibility of the scent management system enables a user (such as a non-NOC employee) to utilize a control application to monitor and control the scent diffusion devices as desired. The system enables intelligent deterministic authorization of roles, permissions, and licensing rights across a diffuser network to maintain brand integrity. Users can control roles, permissions, and licensing rights (e.g., parent/enterprise, franchise, location) across a hierarchical structure to enable diffusion device control at a regional level, such as on a location basis, or at an enterprise level, etc.
The scent management system can be used not only for scent brand shaping and delivery of consistent scent impact, but also for reducing off-flavors, neutralizing off-flavors, advertising products, aromatherapy/stress relief, and the like. Other functional benefits will be described herein.
The odour management system may comprise one or more diffusion devices. Each diffusion device may include a processor (such as a microcontroller) that is capable of reporting information (telemetry data) about the state of the diffuser to one or more cloud-based business applications over the internet. The microcontroller may be capable of autonomously controlling the unit based on control instructions sent by the business application. The business application stores historical data about the diffusion device, which enables this data to be reported and mined to improve the scent management service. NOCs may be utilized to monitor the health of end-user diffusion devices and may react to alerts by adjusting settings of the diffusion devices or by creating work orders (e.g., roll a truck, email to field contacts, etc.) in order to address service issues or refill issues. Alternatively, the device may be self-service, non-NOC managed. In an embodiment, the networked diffusion device forms part of the internet of things.
In one embodiment, an odor management system can comprise: the diffusion device is provided with embedded intelligence realized by an embedded microcontroller module, and is additionally provided with communication capacity realized by a wireless local area network and a wide area network communication module; and a diffusion device network configuration that supports intelligent management of fragrance distribution either locally within a scented environment or remotely by one or more centralized or distributed Network Operations Centers (NOCs) equipped with scent system administrators. The scent management system includes business processes implemented by diffusion devices deployed within a defined scent dissemination network configuration. Throughout this specification, unless the context indicates otherwise, the terms "scent device", "scent dispersion device", "diffuser", "scent diffusion device" or "scent diffuser device" are used interchangeably with each other and with the term "diffusion device". It will be appreciated that the use of scented liquid in the diffusion device is an example of one of the types of liquid that may be used in the scent management system. Indeed, odor neutralizing liquids, disinfectants, make-up removers, or other liquids may also be used in the diffusion device. Throughout this specification, the terms "cartridge," "package," and "reservoir" are used interchangeably with one another, except where the context otherwise dictates. Various aspects of an odor management system are described herein. Additionally, it should be understood that the device may operate to dispense any liquid, such as in the form of a gas or vapor-colloidal mixture. Fig. 1 depicts an exemplary architecture 100 for a scent management system. In this embodiment, master diffusion device 102 is in communication with one or more slave diffusion devices 104 and a server 108, such as a cloud server running a cloud-based business application. In this embodiment, device 102 communicates with server 108 to receive control instructions, system updates, etc. from NOC 118 and transmit telemetry data, etc. thereto. The communication may be over a cellular connection. The devices 102, 104 may be in communication with environmental sensors 110 or have on-board sensors 110. NOC user device 114 may communicate with devices 102, 104 through server 108. The customer control device 120 may be used to control the devices 102, 104 via the server 108. The advertiser network user interface 112 may be in communication with the server 108.
In one embodiment, the scent diffusion device can include a cartridge-based removable reservoir for scented oil or other liquid to be diffused and a diffuser that atomizes the scented oil into particles so as to deliver a targeted and controllable concentration level of the scented oil or liquid. The particles may be of various sizes, such as droplets, or large or small aerosol particles. In embodiments, the diffuser causes little particle settling. The diffuser includes at least one of: droplet generators, atomizers, evaporators, evaporative wicks, saturated solid solutions, and the like.
In one embodiment, the scent diffusion device can include a solid scent media cartridge, such as a thermal energy from a coil, bulb, candle, hot air blower, heat conductive source, or the like, to heat the scent media in the cartridge while a fan blows through the media to distribute the scent. Remotely controlling scent dispersal may involve controlling at least one of a fan or a heat source.
In embodiments, such as where the odor diffusing device may include a wick or other fixed or solid medium, the diffusion rate/efficiency or wicking rate/efficiency may be adjusted over time or periodically, such as by operational aspects or operational parameters of the integral fan. For example, the amount of liquid available for diffusion may decrease over time as the device operates. In some embodiments, the amount of liquid in the device may decrease at a predictable rate, such as at an exponential rate that may be predicted based on a model (such as a physical or chemical model). As the amount of liquid available in the device decreases, it may become increasingly difficult to induce diffusion of the remaining liquid out of the device. This may be due in part to changes over time in aspects or parameters of the fixed medium used to assist diffusion. For example, the wick may dry, the solid fragrance block may dehydrate, and the like. By controlling parameters of the means for promoting diffusion, such as fan speed, adjustments can be made to account for changes in diffusion characteristics. For example, throughout the operation of the diffusion device, the fan speed therein may be adjusted so that when a new cartridge of liquid or other fixed media is placed into the device, the fan runs more slowly and, as a result, the wick or other fixed media may dry out more slowly. The fan may then be accelerated to obtain a relatively consistent level of liquid diffusion from the cartridge or other fixed medium as the device operates and the characteristics of the wick or other solid medium change. In some embodiments, the operation of the fan may approximate an elliptic curve, an exponential curve, or other function suitable for obtaining a continuous level of diffusion of the liquid. In embodiments, such as where the liquid is a scented oil, controlling the fan to achieve a continuous level of diffusion of the scented oil may produce a substantially stable intensity of scent over time.
In one embodiment, a piezoelectric device may be used in the scent diffusion device to cause vibration in the package, such as by the ultrasonic surface wave effect or by using a microscopically porous Vibrating Mesh (VMT). Such vibration may cause oscillatory motion and pressure in the liquid within the package and achieve atomization of the liquid. The piezoelectric device can be remotely managed to control fragrance levels.
Other devices may be used in the system to diffuse the scent, such as those including atomizers with hydraulic spray nozzles, liquid-liquid impingement atomizers, air-jet atomizers, pre-filming atomizers, high-pressure electrospray, and the like.
The diffusion device may also include a pump for effecting a venturi effect or drawing liquid from within the package at a controlled duty cycle to effect diffusion. The diffusing means may comprise a fan to assist in distributing the particles. The fan may be low noise, such as by using a low noise fan or noise cancellation techniques. The diffusion device uses a spreading technique that requires little heat to achieve uniform spreading of the evaporated scented oil throughout the environment. Such techniques allow for flavor integrity to be maintained over time.
In some embodiments, the pump may be a conventional air pump or a variable speed air pump. In the case of a conventional air pump, the scent output may be controlled using a duty cycle, for example, a duty cycle of "on" for 2 minutes and "off" for 4 minutes provides a 33% duty cycle. Various other methods may also be used to control the pump, given the ability to remotely control the operation of the pump in a networked scent diffusion device. One way of controlling the pump is to control the power delivered to the pump from the outside, which can be done by modifying the voltage across the pump. For example, the voltage driving the pump may be remotely increased or decreased, such as within approximately +/-20% of the 10V standard or within a range of 8V to 12V. Controlling the voltage driving the pump enables remote control of the device diffusion rate, independent of the voltage range and independent of the duty cycle. At a given duty cycle, the output can be attenuated or enhanced by simply changing the voltage of the pump. For example, for multiple diffusers deployed in an environment, assuming all diffusers are set to have the same duty cycle, the voltage driving the diffuser deployed in a smaller space of the environment may be lowered to attenuate the output, while the voltage driving the diffuser deployed in a larger space of the environment may be raised to enhance the output. In this example, a duty cycle portion that includes a 1 minute "on" portion at a low speed setting may supply X grams per hour, while the same duty cycle portion that includes a 1 minute "on" portion at a high speed setting may supply 3X grams per hour. The voltage control of the pump enables volume control of the device that operates on a continuous or nearly continuous basis. Being able to control the speed of the compressor or pump may also attenuate the noise generated by the pump. Another way to control a pump with remote control of the pump is to use the characteristics of the pump to modify the performance of the pump, such as by Pulse Width Modulation (PWM) (i.e., changing the fraction of time during which the pump's motor is on within a given time period to affect the pump's output at a given voltage), or Pulse Amplitude Modulation (PAM) (i.e., changing the amplitude of the energy pulses to the pump during the duty cycle), or a combination of PWM and PAM.
In one embodiment, in a venturi effect liquid system, the output rate may vary based on the liquid level of the cartridge. For example, when a liquid cartridge is full, there may be a small amount of air in its headspace, and the headspace may have a diminishing effect on diffusion, because it must overcome the partial vacuum force when the venturi force impinges on the venturi tube. When the cartridge is empty, the partial vacuum force increases with increasing volume of space in the headspace for a given amount of air remaining in the headspace. The end result is: for a fixed air pressure at the top of the venturi, the amount of liquid pulled up the tube per unit time decreases with the liquid level or with the volume of air in the headspace (which creates a reaction force when the vacuum in the headspace is relieved).
In an embodiment, the diffusion output rate is a function of the force caused by the air pressure at the top of the venturi (e.g., the net force on the venturi, which is equal to the venturi force from the pump minus the venturi force from the air vacuum). Further, the venturi force from the vacuum may be an inverse function of the liquid level, such that as the liquid level falls, the vacuum force rises. Thus, the diffusion output rate is an inverse function of the fill level. However, the air pressure from the pump may be programmed to increase accordingly to counteract the vacuum force as well.
With a smart pump, the diffusion device can be programmed to intelligently increase its pressure at the venturi in order to counteract the gradually increasing pressure exerted by the partial vacuum. In other words, a pump parameter (such as the voltage of the pump) may be increased by an amount necessary to counteract the vacuum force. With this approach, the diffusion device can deliver a uniform output rate when the liquid in the cartridge changes from full to empty.
Further, while the scent diffusion device may be programmed to achieve a particular scent impression/level or brand management goal, the device may also receive commands or programming with scent level instructions (e.g., deviation levels) to increase or decrease a duty cycle associated with the programmed scent impression/level or brand management goal. The odor level command may be given in percentage points or as a percentage of the current duty cycle, the amount of time that the cycle is on, the amount of time that the cycle is off, the number of on switches in a cycle having a known duration, or any other algebraic or numerical expression. For example, continuing the example, a conventional air pump or compressor having a 33% duty cycle may be modified by applying a positive or negative offset, such as by indicating that the duty cycle should be increased by +17 percentage points of the full duty cycle. When such a deviation is applied, the duty cycle will increase to 50%.
In other embodiments, odor level instructions (optionally in the form of a bias) may be applied to other operating parameters of the air pump or compressor (such as fan speed, nozzle pressure, size of the nozzle opening, shape of the nozzle, compressor power, voltage or current, duty cycle of the compressor's motor, maximum pressure allowed by the compressor, and/or other device specific parameters) to change the odor impression/level. For example, applying a positive or negative bias to the pump pressure may affect the power amplitude at the pump, which may be proportional to the volume of air output by the pump, which may be proportional to the scent output of the device.
In embodiments, the scent level deviation can be adjusted by a known amount according to an aspect of at least one of the device, the scent being diffused, a target value for a scent parameter, and the like. For example, a given device may be measured to characterize the relationship between the amount diffused and each operating parameter of the device (such as fan speed, nozzle pressure, nozzle size, nozzle shape, fan duty cycle, compressor power, voltage or current, duty cycle of the compressor's motor, maximum pressure allowed by the compressor, etc.).
In embodiments, the duty cycle may be modified by applying a positive or negative odor level bias, and at a given duty cycle, the output may be reduced or enhanced by simply modifying the voltage of the pump. Thus, the basic programming of all devices may be the same, but the output may be managed by altering the pump speed and/or duty cycle.
Monitoring the current, voltage or power of the pump or compressor may also help detect errors, blockages, tampering or other problems with the diffusion device. For example, a typical current range for a diffusion device may be 800mA-1100 mA. If the diffuser is operating at low current (such as 500-. In another example, if the diffusion device is operating at high current, this may indicate that the load is too high, for example due to blockage of the air outlet of the device. In any case, when the detected current is outside of the typical operating current, an alert may be generated and displayed or transmitted, as described herein. In certain embodiments, such as when the current exceeds a threshold, the diffusion device may be turned off remotely or automatically based on preprogrammed actions designed into the device firmware, and an alert may further be generated. In embodiments, the diffusion device may be switched between utilizing one or more on-board cartridges to determine whether a problem is located in the connection between the cartridge and the atomizing assembly, or whether a problem is located in the atomizing assembly itself or downstream of the atomizing assembly.
Referring now to fig. 22, an embodiment of a diffusion device is depicted. In this view, the housing 2202 houses a pump assembly 2204 that pumps liquid up out of a reservoir through a tube attached to a pump and assembled into a fitting 2212. One or more valves, such as solenoid valves 2208, 2210 are placed in line in the tubing to turn the pumping on and off.
The diffusion device may include a programmable microcontroller module with memory (fixed or removable) for controlling device functionality, such as controlling volume, duty cycle, schedule settings, and the like. The diffusion device may include a wireless local area network module capable of communicating with other devices within the physical location via radio frequency communications, including IEEE standards (such as WiFi, zigbee, bluetooth, etc.). Communication protocols that may be used by the diffusion device include one or more of the following: zigbee, MiFi, MiWi, DMX, ANT, Z-Wave, Insteon, JenNet-IP, X10, mesh, visible light, ultrasound, infrared light, IP version 6(IPv6), such as IPv6(6LoWPAN) on low power wireless personal area networks, and neighborhood exchange protocols. The diffusion device may form a machine-to-machine network. The diffusion device may include a removable Wireless Wide Area Network (WWAN) module capable of electronic communication with one or more remote network operation centers over, for example, a telecommunications cellular network. Throughout this disclosure, references to a "network operations center" or "NOC" should be understood to encompass a single centralized center or a group of multiple distributed centers. In an embodiment, the diffusion device may include communication technology for wired installation. Telemetry data such as perfume level refill alerts may be delivered over a communication network. The device firmware may be upgradeable over a network.
In one embodiment, the connector may be adapted to easily configure the communication module or adapted to make the communication module modular on a motherboard of the device, such that the communication module is easily swapped in and out. For example, the device may be manufactured such that the communication module may be installed or exchanged at a dealer, retailer, customer, or other downstream location. For example, the device may be shipped from the manufacturer to the dealer with the cellular communication module installed, but upon receipt, the need for a WiFi-enabled or bluetooth-enabled device may arise. The dealer may be able to turn on the device and switch the cellular communication module to a WiFi-enabled and/or bluetooth-enabled module. In some instances, the device may be able to accommodate multiple communication protocols, such that in this instance, the dealer need only add WiFi and bluetooth modules to the existing cellular module. In other embodiments, the communication module may be embodied in firmware such that the capabilities may be modified through firmware updates, such as delivery over a cellular network via a cellular networking communication protocol, delivery over the internet or other IP-based network, and so forth. In embodiments, the communication module may be embodied in or use a Field Programmable Gate Array (FPGA), such that the communication module may be reprogrammed in the field to meet changing requirements.
The diffusion device may be characterized by "plug and play" ease of installation with AC or DC power, automatic configuration, and NOC "check-in". In general, the diffuser assembly may be very lightweight, such that the assembly may hang from a rail clip or wall, such as 5lb per assembly.
The diffusion device may include a manual programming interface (e.g., user interface, screen, buttons, dials, sliders, touch pads, keyboards, etc.) that allows an individual to manually establish and confirm device settings. In an embodiment, the diffusion device includes a signal that alerts a user of the device status. The status may be related to the sensed liquid level. The signal may be at least one of a light 1028, a color indicator, a message on a text screen, a sound, etc.
In one embodiment, the scent diffusion device can include a processor that monitors the scent diffusion device and generates a status, and a user interface that provides an alert based on the status, wherein the alert triggers an event. The status may be a jam and the event may be a scheduled maintenance. The status may be in need of refill and the event may be at least one of a scheduled refill and an order for additional odorants. The state may be an intervention and the event may be a shutting down of the device.

In one embodiment, one form of the device can operate as a point-of-use scent dispenser installed within a target scent area. In one embodiment, another form of the diffusion device may be integrated into a heating, ventilation, and air conditioning system of a venue, wherein fragrance dispersion occurs through an HVAC duct, PTAC system, or other ventilation system.
In one embodiment, the diffusion device may be embodied in the form factor of a flameless LED candle.
In one embodiment, the diffusion device may include a tamper-proof closure. The tamper-resistant closure may be at least one of a physical key, a software-based key, a biometric key, a retinal scanner, or the like. The physical characteristics of the packaging may also make the diffusion device difficult to tamper with, such as by including at least one of sonic welding, spin welding, bayonet, and the like. The sensor may also act as a tamper-proof mechanism if contact with the on-board sensor is lost while the device is still sensing or utilizing power.
The packaging of the diffusion device may include physical features for tamper-resistance that prevent the packaging from operating properly in devices that are not configured to accept the packaging. For example, the package may include an RFID tag 1208 for identification, and the RFID tag must be read correctly or the diffusion device will not function. Reading the RFID tag may be performed on the device by an integrated RFID reader, such as at the time of installation of the package or during routine inspection, or may be performed using a separate RFID reader. In embodiments, NFC ID and NFC reader may be used instead of or in addition to RFID tags and RFID readers. In another example, the package may include another identification tag, such as a barcode 1204 or QR code 1202, that may be imaged by an onboard imaging device or a separate imager. The images may be transmitted to the NOC for analysis and approval or storage. In one embodiment, there may be electrical contacts that need to be between the package and the device when the package is installed.

An alert may be sent over the network if the package is removed, such as if the package is removed early (e.g., a level sensor indicates that sufficient liquid remains), regardless of the underlying instructions being removed (e.g., removed without a work order, removed by a non-technician), and so forth.

In one embodiment, a method for securing a networked odor diffusion device may comprise: associating 2102 a tamper-proof identifier with a reservoir and atomizer head assembly of a networked scent diffusion device; determining whether a tamper-proof identifier is present on the reservoir or nebulizer head assembly 2104; if the tamper-proof identifier is not present, diffusion is blocked and the absence of the tamper-proof identifier is communicated to other networked scent diffusion devices 2108. In another embodiment, in one embodiment, a method for fastening a networked odor diffusion device may comprise: associating a tamper-proof identifier with a reservoir of a networked scent diffusion device; determining whether an anti-tampering identifier is present on the reservoir; blocking diffusion if the tamper-proof identifier is not present, and communicating the absence of the tamper-proof identifier to other networked scent diffusion devices.
In one embodiment, a diffusion device for atomizing a liquid may comprise: at least two reservoirs containing a liquid; a liquid level sensor disposed in the apparatus; a tamper-proof identifier associated with at least one of the reservoir and the switch; and a processor operatively coupled to the liquid level sensor for generating a first signal indicative of the liquid level, a second signal indicative of the presence of the tamper-proof identifier, and generating control instructions for the switch based on the first signal and the second signal to cause the device to switch from utilizing one reservoir of the nebulizing diffusing device to utilizing a different reservoir of the nebulizing diffusing device.
In one embodiment, a method for operating a networked scent diffusion device in an environment to achieve scent impression goals may comprise: an indication 2002 received at the networked scent diffusion device that diffusion from one or more other networked scent diffusion devices is blocked due to an intervention indication; accessing an environmental model of an environment, wherein the model includes one or more networked scent diffusion devices 2004; and programming the scent diffusion profile of the environment to be executed by one or more of the remaining unblocked networked scent diffusion devices to achieve the scent impression goal 2008. In certain embodiments, the model comprises two or more networked odor diffusion devices.
In one embodiment, the atomizing diffusion device may comprise: at least two packages having a liquid disposed in a diffusion device; a tamper-proof identifier associated with at least one of the packages; and a processor operatively coupled to the scent diffusion apparatus, the processor determining an intervention indication based on the tamper-proof identifier and causing a switch between packages based on the intervention indication.
In one embodiment, the diffusion device may include a chemical sensor in fluid communication with the package for detecting the presence of a particular component in a liquid, such as one disposed within the package. The specific component may be a tag or tag molecule placed in the package such that when the tag or tag is detected, the package is authenticated. Conversely, if the label or tracer is not present, the package may be identified as potentially fraudulent. In embodiments, the chemical sensor may be disposed outside the package, but may be in fluid communication with the contents of the package in order to sample the liquid of the package to determine the presence or absence of a particular label or tracer component. If the chemical sensor detects a particular component and thus authenticates the package, the device may continue to operate to disperse the liquid, as described herein. If no particular component is detected, various actions may be taken. For example, a visual or audible signal may be generated, such as a flashing light (e.g., an LED) or beep, or any other visual, audible, tactile, or other sensor prompt that will alert a user or observer of a potential problem, such as various types of cues known to those of ordinary skill in the art. Such a signal may indicate the absence of a particular component, which may be due to tampering, incorrect packaging, exhausted packaging, error, etc. In other embodiments, the signal takes the form of a message, alert, or communication transmitted over a network to a device such as a central location, individual, manager, computer, mobile device, or the like. In certain embodiments, the chemical sensor may sample the air for a particular constituent, and when no constituent is present in the air, the sensor may send an instruction to the diffusion device via the network to cease operation.
In embodiments, the packaging may be embodied in a box, reservoir, pouch, balloon, film, or the like. Referring to fig. 4, a cartridge for a scent management system includes a liquid reservoir 404 and a nebulizer head assembly 402, wherein the liquid reservoir is positioned below the nebulizer head. The liquid reservoir has a substantially cup-shaped geometry and its top edge is joined to the atomizer head assembly, such as by an ultrasonic weld, a twist lock with an o-ring seal, or the like, such that the reservoir is open to the expansion chamber. A conduit or tube 408 for conveying the liquid in the reservoir is attached at its first end to the atomizer head, and the second end of the tube or a channel therein extends into the liquid 410 within the reservoir, preferably extending sufficiently below the surface of the liquid to maximize the total volume of liquid drawn from the reservoir when the liquid within the cartridge is depleted. There may be some condensation, but the excess liquid mostly remains and falls back into the reservoir. The cone-like structure may be configured to use impaction to coalesce atomized particles that do not diffuse back into liquid form to form aggregated oil that falls back into the reservoir.
The atomizer head may have a gas (e.g., air) inlet passage 412 having one end in fluid communication with a source of compressed air. A second end of the gas inlet passageway may be in fluid communication with an orifice plate 418 including a flow restriction orifice 420. In certain embodiments, a venturi may be used in place of an orifice plate. The orifice plate separates the gas entry passage from the mixing chamber 422. The mixing chamber has a wall opposite the orifice plate, the opposite wall having an atomization orifice 422. The other wall of the mixing chamber may have an opening 424 in fluid communication with the tube. The atomization holes may be in fluid communication with the expansion chamber 428. The expansion chamber may be in fluid communication with the muffling chamber 430. The muffling chamber can have an outlet 432 to the ambient environment to be treated with the atomized liquid.
The operation of the atomizer head may be as follows: the compressed gas flows into the passageway, through the restricted orifice of the orifice plate and into the mixing chamber. This creates a relatively high pressure region on the gas entry passageway side of the restrictor orifice and the gas flow velocity out of the restrictor orifice increases and creates a relatively low pressure region at the mixing chamber end of the restrictor orifice. The relatively low pressure draws liquid from the reservoir through the tube into the mixing chamber and the liquid joins the flow path of the gas out of the orifice of the restrictor, thereby creating a gas and liquid mixture. The gas-liquid mixture then passes through the atomization holes into the expansion chamber, thereby producing an atomized gas and liquid mixture. The atomized gas and liquid mixture flows into the muffling chamber and the atomized liquid and gas flow through the outlet into the ambient to be disposed of.
As the atomized gas and liquid mixture flows through the expansion and muffling chambers, a portion impinges on the surfaces of these chambers and the walls separating these chambers. This results in a large portion of the larger atomized liquid particles being removed from the atomized liquid and gas mixture. The larger particles condense back into liquid and flow back into the reservoir. Furthermore, any liquid that is not fully atomized after the gas and liquid pass through the atomization holes flows back into the reservoir. The muffling chamber also acts as a sound level suppressor, thereby muffling the sound of the gas and atomized liquid flowing through the atomizer head assembly. Other optional methods of attenuating the sound of the diffusing means, which may be used independently or in combination with each other, may be: extending the length of tubing on the intake side of the pump (such as by making the length about 6 inches, for example); increasing the size of the reservoir (such as, for example, by making the size about 30 ml); adding a reservoir, such as a second chamber, to the output of the diffusion device, as will be described further herein (e.g., such as by adding a linear array of reservoirs extending from the diffusion device); extending a diffuser output tube into the headspace; and so on. For example, on the outlet side of the pump, the orifice may be provided with a Y-valve that splits the outlet flow, thereby reducing the outlet sound. In embodiments, the bladder or second chamber may be provided at the end of one branch of the Y, or it may coincide with the outlet of the pump. The cartridge is inserted into the diffusion device with the compressed gas inlet passage coupled with an air fitting 414 to provide a supply of compressed gas to the cartridge.
The package may be used in the diffusion devices described herein, but may also be used in other scent diffusion devices, such as devices that plug into a wall outlet.
In one aspect, a package for use with an odor diffusing device may include: a reservoir containing a liquid and an atomizer head assembly, wherein the reservoir is joined to the atomizer head assembly at a top edge of the reservoir; and a tube for delivering the liquid in the reservoir, wherein the tube is joined on a first end to the atomizer head assembly and a second end of the tube extends below the surface of the liquid. The gas inlet passage of the atomizer head assembly may have one end in fluid communication with a source of compressed air and a second end of the gas inlet passage in fluid communication with an orifice plate including a flow-restricting orifice. The mixing chamber and the gas entry passageway of the atomizer head assembly may be separated by an orifice plate, the mixing chamber having a first wall opposite the orifice plate including an atomizing orifice and a second wall including an opening in fluid communication with the tube. The expansion chamber may be in fluid communication with the atomization orifice and an anechoic chamber having an outlet to ambient. Gas flowing into the gas inlet passageway through the restrictor orifice creates a region of relatively low pressure in the mixing chamber which causes liquid from the reservoir to be drawn through the tube into the mixing chamber where it joins the flow path of the gas out of the restrictor orifice, thereby creating a gas and liquid mixture which is then atomised as it passes through the atomising orifice. The liquid reservoir may have a substantially cup-shaped geometry. The top edge of the reservoir may be joined to the atomizer head assembly by one of an ultrasonic weld and a twist lock with an o-ring seal.
In embodiments, certain diffusion devices may be capable of dispersing multiple fragrances and other liquids. In embodiments, the networked odor diffusion device may include the ability to accept multiple packages (also referred to as cartridges or reservoirs) for operation in multiple configurations. The diffusion device may be capable of receiving multiple packages, such as more than one package. In one example, the diffusion device has two packages. When one package is depleted or nearly depleted, the diffusion means may switch to diffusion from a second package. In another example, the diffusion device can accept four packages, where two packages house a first flavoring and two other packages house a second flavoring, such that both the first flavoring and the second flavoring each have a spare package, and the diffusion device can automatically switch to a new package when one package is empty or nearly depleted. In embodiments, the combined volume of liquid in the package mounted in the device may be greater than a percentage of the expected usage in one refill service cycle. For example, the combined volume of liquid may be greater than 50% of the expected usage in the service period. The switching between packages may be done when a depletion or near depletion of the package is sensed, or may be done on another basis, such as after a certain elapsed time, during the day or night, upon detection of a certain condition, upon detection of a user, etc. The handover system is described elsewhere herein. In another example, switching between packages may be performed according to a correlation and priority order between devices, such as determined by a master device. Devices may be related to each other for the purpose of coordinating activities in a space. The priority may be predetermined, determined in coordination with a plan, determined on a continuous basis, determined based on sensor feedback, and so forth. For example, three related devices in a region may each diffuse one of odorant a, odorant B, and odorant C at the three devices. The master device may determine that a larger odorant B is needed in the region. Upon this command, all three devices can make any necessary changes in the correlation to achieve this odor goal; for example, all three devices can be programmed to switch to diffusing agent B in such a situation, or the devices of diffusing agent A and diffusing agent C can be programmed to reduce these odors or cease diffusing these odors. For example, if one device does not have odorant B, but because it is associated with other devices, it may take another action to attempt to achieve the goal. There may be priority in the packaging to assist in achieving the odor target. For example, if flavor B contains certain components of a formulation, other flavors having similar components may be prioritized. In such an example, the device may be programmed to switch itself to the on-board scent with the highest priority, i.e., the formulation closest to scent B.
In another example, the diffusion device may operate with multiple fragrance packages, and each package may house different flavor notes (notes) of different scent tonalities (chord) that the diffusion device may be programmed to blend to form the scent tonalities. In embodiments, the scent mood may be a particular combination of "base taste order", "medium taste order" and/or "high taste order". The scent mood may be specified by a brand/media activity specification.
In order to maintain consistent phase in environments where the scented oil in the reservoir may undergo some evaporation or depletion, certain approaches may be taken. Scented oils are mixtures of numerous liquids, each having a different partial pressure. When using atomization, the components with higher vapor pressure will flash off earlier and the heavier components will be recycled back into the oil reservoir. The net effect is: the scented oil is depleted of the scent mood, or the resulting scent will actually change. One way to potentially affect this effect is to vary the duty cycle of the diffuser means as the liquid level is depleted (e.g. increase t in duty cycle). Knowing the liquid level by sensors, direct measurement or estimation enables the application of a correction factor t to maintain the fragrance mood. Another method may involve the use of a second cartridge. In this scenario, if the main cartridge is partially depleted, adding a small amount of scented oil from the scented oil contained in the second cartridge will add the top note back to the scent base.
In one embodiment, as the scented oil in the package of the diffuser device having the scented oil recirculation feature is depleted over time, the average size of the molecules in the remaining scented oil increases. One statistical interpretation is: larger flavor oil molecules are more likely to fall back into the package through a recycle feature during atomization. Such average molecular size variations can affect the performance of the diffuser and can result in lower odor diffusion rates for a fixed duty cycle setting. The process for adjusting the duty cycle of the diffuser means to compensate for such average molecular size variation and reduced diffusion rate may comprise: increasing duty cycle, pump pressure, or other diffuser settings that affect diffusion rate. In one embodiment, a liquid level sensor of the diffusion device may determine the liquid level remaining in the package, and a processor of the diffusion device may use the sensed liquid level to modify the diffuser settings described herein in order to maintain a desired odor diffusion rate, odor target value, or brand management target. A method may include: receiving a sensed liquid level in a package of the scent diffusion device, wherein non-atomized scent oil is recirculated back into the package during operation of the device; and adjusting the duty cycle of the diffusion device to maintain a desired rate of scent diffusion. The adjustment may include at least one of increasing a duty cycle, increasing a pump pressure, and changing a diffuser setting.
In another example, the diffusion device may be capable of accepting multiple packages, and switching between packages is done as a function of time, such as to deliver daytime and nighttime scents. In yet another example, the diffusion device can accept multiple packages, where one package includes the odor neutralization agent and one or more other packages include the fragrance, such as the diffusion device can be switched to the odor neutralization agent or switched in between dispensing different fragrances as desired. In yet another example, the diffusion device may house multiple packages, and the desired package may be selected remotely. For example, when a guest arrives at a hotel lobby, they may choose a particular scent to diffuse in their hotel room. The scent diffusion may be remotely triggered. Continuing the example, the guest may pick the scent in advance at the time of the reservation or some time before arrival, such that the scent is triggered when the room becomes available to the guest, when the guest registers for check-in, when the guest enters the room and is sensed by the occupancy sensor or bluetooth/WiFi sensor, or the like. In yet another example, the diffusion device may house multiple packages, and the liquids in the packages may be blended prior to diffusion.
In yet another example, one of the packages may be a diluent that reconstitutes the concentrated scented oil, and the blending may be performed at the level of the diffuser. Blending may be programmed to produce a scent concentration factor specified by brand/media activity specifications. In this example, multiple concentrated fragrances may be available for use in a diffusion device (such as in a rotating shelf), and one or more of the multiple fragrances may be selected for diffusion.
In another example, the diffusion device may accept a disposable fragrance package in addition to or in lieu of the existing two-pack configuration. For example, guests at a hotel may be offered a selection of various disposable fragrance packages in the lobby that themselves may be installed into the diffuser. In yet another example, the scent in the package may be provided by crystals, powder, or another non-liquid element that is recombined or diluted prior to diffusion.
In embodiments, the fragrance used by the diffusion device may match the scent to be used in a passive scent device, such as a candle, pie or gel. The perfume may be delivered as an oil or as a solid, such as a solid crystal.
The switching between packages may be performed using an automated switching system. An automated switching system for a networked scent diffusion device housing a plurality of fragrance packages enables switching between packages when certain conditions are met. For example, the condition may be a determination that the level of fragrance in the package is low. In another example, switching may be performed after a certain elapsed time in a programming transition to mitigate odor desensitization. In an implementation, the device may utilize a FIFO refill process.
In an embodiment, the switching system employs a valve. In embodiments, the switching system employs a liquid level sensor, such as an electrical liquid level sensor (e.g., a conductive transmitter; a capacitive transmitter for measuring cumulative capacitance as a function of liquid amount and based on the dielectric constant of the liquid; a resistive transmitter; a semiconductor sensor for reading the strength and profile of a magnetic field to provide a vector, such that the liquid level can be determined by triangulation based on only two sensors); magnetic liquid level sensors (e.g., Hall effect sensors or Hall effect switches; reed switches/magnetic technology; magnetic confinement, magnetoresistance, resistor chains); mechanical level sensors (e.g., level floats of trigger switches, physical switches, strain gauges); optical level sensors (e.g., imaging sensors, level float plus imaging sensors); static pressure sensors (e.g., displacers, bubblers, differential pressure transmitters) for measuring the pressure of the liquid; a load cell for measuring mass in the package; an electromagnetic transceiver that transmits EM signals at the surface of the liquid that reflects the EM signals to its receiver with a time delay that is used to calculate the liquid level (depending on the wavelength of the EM signals sent and received, EM may be ultrasonic, laser, radar, etc.); a microwave sensor; or any other level sensor. In one embodiment, the level sensor may include a floating magnet disposed within a track inside the package, wherein the floating magnet moves within the track as the level of the liquid changes. At least one hall effect sensor or hall effect switch is arranged outside the package, wherein the hall effect sensor or hall effect switch is arranged in such a way that it senses the position of the magnet. In one embodiment, the switch may be activated when a particular position of the magnet, which may correspond to a predetermined liquid level, is sensed, which causes movement from a first state of the switch to a second state of the switch. The switch may be used to switch the use of one package by the diffusion device to the use of another package. For example, the switch may be a solenoid switch between packages. In another embodiment, data from the level sensor can be used to monitor the level of liquid within one or more packages in the diffuser device and predict when the packages will run out of liquid. This prediction can be used to schedule a refill service so that the diffusion device is never starved of liquid. As part of the predictive model, the NOC, local controller, gateway device, or any of these devices may perform supply day calculations using algorithms to determine when the packages in the device will be depleted. The algorithm may utilize the measured current level and divide the average daily usage rate by the measured current level to determine the remaining days of supply. The average daily usage rate may be defined for any desired period of time. The results of the calculations can be used to schedule events such as just-in-time changes of packaging, scheduling of refilling technicians, or transmitting alerts/emails to field personnel. The supply day calculation may also use an estimated liquid level instead of the measured liquid level, wherein the estimated value may be determined based on the duty cycle used by the device, optionally in combination with other historical or modeled data regarding the operation of the device. The supply days calculation can also utilize information (such as duration of operation, compressed gas usage, etc.) instead of the measured liquid level in order to estimate the amount of liquid remaining. In one embodiment, a level sensor for a networked scent diffusion device provides a real-time scent level and causes an alert or signal to be generated when a reading from the level sensor indicates that a package needs to be replaced, when an unintended reading is obtained, and the like. In response to receiving the unexpected reading, control instructions may be sent to the device to shut down the device or otherwise abort the diffusion operation. If the reading is higher than expected (potentially suggesting a jam), control instructions may be sent to the device to switch to a new package. In this example and throughout this specification, the alert or signal may be one or more of visual, audio, electronic (e.g., SMS/MMS, text, email, pop-up, etc.), and the like. Throughout this specification, alerts may be sent asynchronously when a device reports an event, or if a device stops reporting to the NOC for a predetermined period. Throughout this specification, an alert may be triggered whenever the device goes from a non-alert state to an alert state. If two of the same alerts are reported in succession, the second alert will not cause the device to re-trigger the new alert-instead it will consider the alarm to be in the setting. The audio alert may be emitted through a speaker of the diffusion device. The visual alert may be emitted by an LED light of the device, and so on. In another example, a predictive algorithm may be used to estimate the actual liquid level based on data regarding the duty cycle and the SCF. A single sensor near the empty level of the reservoir can be used to verify the level.
In one aspect, the atomizing diffuser can include a floating magnet disposed within a track inside at least one package for the diffuser having a liquid, wherein the floating magnet moves substantially vertically along the track as a liquid level within the package changes. The apparatus may further comprise at least one hall effect sensor or hall effect switch disposed outside the liquid at a location that enables sensing of the position of the floating magnet in the track. The apparatus may further comprise: a processor operatively coupled to the hall effect sensor or hall effect switch for generating a signal indicative of the sensed position of the floating magnet and generating control instructions for the switch based on the signal; and a switch operatively coupled to the processor, the switch receiving a control instruction from the processor, wherein the control instruction causes the diffusion device to switch from utilizing one package in the diffusion device to utilizing a different package in the diffusion device. The switch may be a solenoid switch. The claimed apparatus may also include a scheduling facility that receives the signal and predicts when the package will run out of liquid or determines a package refill schedule. The apparatus may also include a remote computer in communication with the processor for receiving the signal and generating an alert if the signal indicates a need to replace the package or if an unexpected signal is obtained. The processor may be adapted to send a signal indicating switching to a different package in the diffuser device
In an embodiment, the switching system employs a sensor that measures the pressure in the package to determine the presence of a vacuum or threshold pressure/partial pressure. Certain pressure readings may be associated with the liquid level in the package. When a certain predetermined pressure reading is obtained, the reading may cause an alert or signal to be generated indicating that the package needs to be replaced, an unexpected reading, or the like.
In embodiments, the switching system employs a camera or other imaging facility to monitor the liquid level within the package. For example, the package may have a transparent portion that may allow the camera to image the liquid level. When the camera determines that the liquid level has fallen to a certain point, an alert or signal is generated indicating that the package needs to be replaced, an unexpected reading, etc.
In an embodiment and referring to fig. 10A and 10B, the atomizing diffusion system 1000 can include a housing 1002 containing at least two packages 1004 with liquid in fluid communication with at least one diffuser 1008 and one sensor 1010. In an embodiment, the sensor 1010 is a level sensor 1010 that determines a level of liquid in at least one of the packages. In an embodiment, the sensor 1010 may be an imaging sensor, a hall effect sensor, a flow/occupancy sensor, or the like. The system further comprises a processor 1012 operatively coupled to the liquid level sensor for generating a signal indicative of the liquid level and generating control instructions for a user switch 1014 based on the signal, wherein the switch is operatively coupled to the processor and receives the control instructions from the processor. The control instructions cause the diffusion system to switch from utilizing one package in the diffusion system to utilizing a different package in the diffusion system. In some embodiments of the system, the system switches between the first diffuser 1020 and the second diffuser 1018. In some embodiments of the system, the system switches packages associated with individual diffusers 1008, 1018, 1020. The level sensor may be an imaging sensor, wherein the level of liquid within the package is exposed through at least one of a transparent wall and a transparent window of the package. The switch may be a solenoid switch. The device may also include a communication facility 1022 that enables the processor to transmit a signal to a remote computer, where the remote computer uses the signal to generate an alert if the signal indicates a need to change the package or upon obtaining an unexpected signal, or to predict when the package will run out of liquid, or to determine a package refill schedule. The liquid level sensor may include: a floating magnet disposed within at least one internal track in the package, wherein the floating magnet moves substantially vertically along the track as the liquid level within the package changes; and at least one of a hall effect sensor and a hall effect switch disposed outside the package at a location that enables sensing of the position of the floating magnet in the track. The atomizing diffusion device may be an odor diffusion device.
In some embodiments, an atomizing diffusion system includes at least two packages having a liquid in fluid communication with at least one diffuser; a level sensor that determines a level of liquid in at least one of the packages; and a processor operatively coupled to the liquid level sensor for generating a signal indicative of the liquid level and control instructions for altering a state of the diffusion system. In some cases, the altered state is a switch between packages. In other cases, the altered state is a shutdown of the device.

The level sensor plate 2412 has a plurality of hall effect sensors, and the level of liquid in the cassette is measured when the magnet floating in the cassette passes the hall effect sensors. The sensors themselves are located on opposite sides of the view of the plate 2412 in fig. 24D. Seen in fig. 24D is board 2412 and the circuit traces that extend to each sensor on the other side.

The calculation may involve taking the measured current level and dividing the average daily usage rate by the measured current level to determine the remaining days of supply. The average daily usage rate may be defined for a period of time. The method may also include replenishing based on a schedule. The method may further comprise: generating a control instruction for the switch based on the signal, and receiving the control instruction from the processor, wherein the control instruction causes the diffusion device to switch from utilizing one package in the diffusion device to utilizing a different package also configured in the diffusion device.

The calculation may involve operating duration or compressed gas usage in place of the measured liquid level in order to estimate the amount of liquid remaining. The average daily usage rate may be defined for a period of time. The method may include replenishing based on a schedule. The estimated liquid level may be determined based on a duty cycle used by the device or based on historical or modeled data regarding device operation.
In one embodiment, a method of coordinating one or more plans for an aerosolization diffusion device, such as an odor diffusion device, within a service environment may comprise: providing a plurality of scent diffusion devices within an environment, wherein each diffusion device includes a communication facility that enables transmission and reception of signals to and from a remote computer; at least one liquid level sensor is arranged in each diffusion device; receiving, at a remote computer, liquid level data from a plurality of diffusion devices; and determining, by the remote computer, one or more available or optimized plans for servicing the diffusion device based on the liquid level data. The one or more plans may relate to one or more of the following: production of flavor and fragrance, procurement of flavor and fragrance, management of flavor inventory, delivery of flavor inventory, and scheduling or coordination of resources to achieve efficient or optimized service planning for a plurality of devices within an environment. In embodiments, the plan encompasses servicing atomizing diffusion devices within a plurality of environments.
In one aspect, a method relating to an atomizing diffusion device within a plurality of environments may comprise: accessing an electronic data structure characterizing physical parameters of a plurality of remote diffusion devices disposed within a plurality of environments, wherein the electronic data structure includes data specifying at least one of: production of flavor and fragrance, procurement of flavor and fragrance, management of flavor inventory, delivery of flavor inventory, and scheduling or reconciling resources to effect the transition 1102; accessing the relevant logistics data 1104 at the remote computer; a service plan 1108 is provided for the diffusion device based on the electronic data structure and the related logistics data. The method may further comprise: accessing, at a remote computer, related logistics data at the remote computer; and determining, by the remote computer, one or more plans for servicing the diffusion device based on the liquid level and the logistics data. The logistics data may include at least one of a location of each environment or diffusion device, transportation map data, and a route optimization algorithm. The liquid level is measured using an imaging sensor. The liquid level within the package of the atomizing diffusion device may be exposed through at least one of a transparent wall and a transparent window of the package. The liquid level sensor may include: a floating magnet disposed within at least one internal track in the package, wherein the floating magnet moves substantially vertically along the track as the liquid level within the package changes; and at least one of a hall effect sensor and a hall effect switch disposed outside the package at a location that enables sensing of the position of the floating magnet in the track. Determining the plan may include: performing a supply day calculation, wherein the calculation involves taking the measured liquid level and dividing the measured liquid level by an average daily usage rate to determine a remaining number of supply days, and wherein the average daily usage rate is defined for a period of time. Scheduling and coordination of resources may include scheduling replenishment technicians or transmitting alerts/emails to field personnel. The electronic data structure may be generated at the computer based on the liquid level data from the plurality of remote atomizing diffusion devices. Each diffusion device may include a communication facility that enables transmission and reception of signals to and from a remote computer and at least one level sensor. The liquid level may be measured using a level sensor comprising: a floating magnet disposed within a track inside at least one package of the atomizing diffusion device, wherein the floating magnet moves substantially vertically along the track as a liquid level within the package changes; and at least one of a hall effect sensor and a hall effect switch disposed outside the package at a location that enables sensing of the position of the floating magnet in the track. The physical parameter may relate to a liquid level of the diffusion device.
In one embodiment, the atomizing diffusion device can include at least two packages having a liquid in fluid communication with the odor diffusion device, wherein a liquid level within the packages is exposed through at least one of a transparent wall and a transparent window of the packages. At least one imaging sensor may be disposed outside the package in the diffuser device to image the liquid level in the package. The processor may be operatively coupled to the imaging sensor to generate a signal indicative of the liquid level and to generate control instructions for the switch based on the signal. The switch may be operatively coupled to the processor to receive a control instruction from the processor, wherein the control instruction causes the diffusion device to switch from utilizing one package in the diffusion device to utilizing a different package in the diffusion device. The processor may be adapted to send a signal indicating switching to a different package in the diffuser device.
In an embodiment, the level sensor may be used in conjunction with another measurement to determine whether the diffusion device is functioning properly. For example, if the level sensor indicates a particular level of liquid within the package, but the pump activity and/or the rate of consumption of compressed air indicates that more liquid should have been depleted, an alert or signal may be generated that causes an unexpected reading. Such unintended readings may be caused by a leaking or blocked atomizing nozzle in the system or any of a number of possible failures or performance problems.
In one aspect, an atomizing diffusion device can comprise: at least two packages having a liquid in fluid communication with an odor diffusing device, wherein a first package contains a neutralizing agent and a second package contains an odor agent; a communication facility that receives data regarding the detected malodor; and a processor for executing control instructions based on the data to cause the diffusing device to diffuse at least one of a neutralizing agent, a flavoring agent, and a mixture of the two to counteract malodor. Data may be obtained from environmental sensors. The control instructions may be to vary the diffusion duty cycle of the odor and neutralizing agent. Varying the duty cycle may involve a solenoid opening for each package for a certain% of the duty cycle. Data can be obtained from a wind direction sensor or humidity sensor that detects that the neighborhood odor is drifting towards a location full of odor.
In one embodiment, wireless networked diffusion devices communicate with each other through a networking protocol, wherein the communication between the devices enables the generation of a consistent scent distribution over a wide area. Each diffusion device can operate in several modes depending on the presence of the WWAN module within the device and its activation scheme. With the WWAN module installed, the device may automatically configure itself in a "gateway mode" and may be referred to as a scent gateway device. In the case where the WWAN module is not installed, the device may be referred to as a scent node device. In any case, the device may also include a LAN card. The devices may be in communication with each other or may be independent. Alternatively, in some local networking scenarios, the devices may be hardwired to each other and/or a central networking device. In some embodiments, the device may transmit and receive communications through the cloud server.
In one scenario, a scent dissemination network is established comprising one scent gateway device and one or more scent node devices, wherein the scent gateway device and the scent node devices may be diffusion devices as described herein. In one embodiment, this may be accomplished in the following manner: 1) installing and plugging the scent gateway device into an AC or DC power supply; 2) the start-up scheme within the scent gateway device includes self-diagnostics followed by activation of the WWAN module and establishment of communication with the NOC; 3) the scent gateway device then receives configuration settings from the NOC and begins to disseminate scents according to its downloaded programming; 4) after establishing its own configuration, the scent gateway apparatus searches its wireless local area network for a scent node apparatus; 5) after identifying the scent node devices, the scent gateway device then establishes communication with each scent node device; 6) the scent gateway devices collect information from each scent node device and then relay the information to the NOC; 7) the NOC receiving device information through the scent gateway devices and communicating program settings and information to each scent node device; 8) each scent node device, after having received its configuration settings from the NOC through the scent gateway device, begins to disseminate scents according to its downloaded programming. This exemplary scenario provides remote and centralized management of the scent dissemination network by a scent gateway device, which is a scent dissemination device that also acts as a network gateway. Communication between devices may occur through various networking protocols listed elsewhere herein, such as bluetooth (full power and LE), MiWi, zigbee, and the like. In embodiments, for large areas, multiple gateway devices may be deployed to establish one or more scent dissemination networks in one location.
Once the scent distribution network is established, the scent gateway device can continue to communicate and store data and instructions to and from each paired or associated scent distribution device within the venue, and then relay the data and instructions between the NOC and each scent distribution device. In this way, the status of the scent distribution network and each device is periodically communicated to the NOC, and the NOC administrator can remotely monitor the scent distribution network operation and control the devices to take action to ensure that the scent distribution meets commercial brand standards or other parameters. In one embodiment, the scent dissemination network includes only scent gateway devices in communication with the NOC and no associated or networked scent node devices. In one embodiment, the gateway device may not be the scent diffusion device itself, but the device in communication with the gateway device may be the scent diffusion device and/or other networked devices. The scent diffusion device and/or other networked devices may communicate with the gateway device by any communication means, such as by MiWi. Using MiWi, any information may be periodically broadcast to the gateway device, such as information from sensors disposed on the scent diffusion device and/or other networked devices. Such information may be used to provide feedback, report status, generate alerts or messages, and the like.
The NOC may include a database of all diffusion devices in the field that includes information such as device type, location, customer, sensor readings from the diffusion devices, scent diffusion level, scented oil volume, scented oil type, package/reservoir type, compressed air volume, number of devices in the local network, on/off status, any alerts, current firmware, licensing rights, and security settings, etc. Any device settings or status may be observed and/or controlled by the NOC user. And the NOC is realized as follows: the report is run to check system health and efficiency at the customer location and generate an alert when a diffuser problem is detected at the customer site. And the NOC is realized as follows: managing cellular wireless provisioning, accounts, usage; remotely managing a local wireless mesh network for interconnecting diffusion devices at customer sites; managing firmware updates in the field; collecting telemetry data from the diffusion device over the internet using a centralized software application; and so on. The ticketing and workflow facilities described elsewhere herein for the raised alerts may allow a NOC user to record a response to the alert and communicate the ticket to a person (e.g., a service technician) who may resolve the alert. Fig. 2 depicts an embodiment of a scent management system 200 that enables remote control, monitoring, and management of scent devices from a central NOC. In this embodiment, enterprise applications 202 for workflow, analysis, and support, and customer apps 204 for mobile and web control may interface with NOC software 208, which NOC software 208 may run in NOC 118. Enterprise applications 202 may run on the NOC user device 114. A customer app, such as a customer control app, may run on the customer control device 120. NOC software 208 may include features such as virtualization device services, web service APIs, real-time alert engines, distributed data storage, data rate services, account management, firmware upgrade manager, secure networks and dates, and scalable cloud architectures. In this embodiment, the NOC 208 communicates with the diffusion device 210 through a WiFi or cellular internet gateway, and the diffusion device 210 may be locally networked, such as zigbee networked. Fig. 3 depicts an embodiment of an enterprise architecture 300. In this embodiment, architecture 300 includes a billing and finance facility 302 that receives billing and payable data from a device management facility 308; an inventory management facility 304 that interfaces with a device management facility 308 for purposes of exchanging information regarding new devices, repairs, and replacements; a NOC 118 for monitoring diffusers 102, 104 via an equipment management facility 308; a ticketing and workflow 310 that interfaces with the NOC 118, the device management facility 308, and the service technician interface 314 for generating and managing tickets for service employees; a customer interface 312 for viewing diffuser status and adjusting settings; and a service technician interface 314 to receive service requests and update status, installation, and service diffusers.
For example, a system administrator in the NOC can consult status data received from devices within the scent distribution network, control the program settings of all networked scent devices, identify performance issues within the scent distribution network, schedule refill of fragrance cartridges, and schedule maintenance, repair, or replacement of malfunctioning networked scent devices, among other things. NOC administrators can accomplish such tasks manually by reviewing status data and making changes in real-time, or by allowing NOC software to automatically take action to maintain and support the scent dissemination network based on pre-established rules and heuristics. Fig. 6 depicts an exemplary embodiment of a NOC system view 600. In this view, tabs for alerts, devices, information, users, and search windows are visible. The installation site window lists sites of a parent company (e.g., hotel a, hotel B, hotel C), sites that are subsidiaries or are otherwise associated with a parent company (e.g., hotel a1, hotel a2), and in addition sites associated with a second level of the company hierarchy (e.g., hotel a 1-location 1, hotel a 1-location 2, hotel a 1-location 3). In this figure, the user tab is exposed to indicate who is the installation contact point. Fig. 7 depicts an exemplary embodiment of an overview 700 of a diffusion device at a particular location. In this example, a diffuser is listed, a map of the location with the site is shown, alerts are shown, and any NOC-specific function (such as adding a diffuser or gateway) may be shown. For the diffuser list, information such as current settings, current fragrance level, WiMi signal strength, and device type may be shown along with any other diffuser or sensor data. Each diffuser may be selected so that the user may look down the details of the diffuser. FIG. 8 depicts an exemplary implementation of a view 800 of "look-down" to diffusion device data. The current scent level, current settings, schedule, scent level/FCL (scent concentration level)/SCF (scent concentration coefficient) history, and temperature history, as well as any other diffuser or sensor data, may be shown.
In one embodiment, a user interface for a scent diffusion device network may comprise: a device management and monitoring (DM & M) facility having a configurable dashboard to enable a plurality of activities for a network of scent diffusion devices; and a security facility to set one or more permissions for the activity. The activity may be at least one of: viewing diffusion device telemetry data, a map of diffusion device location, receiving liquid level readings or other meter/sensor readings, providing control instructions to the diffusion device, reviewing status of and managing scent operation of one or more networks of scent diffusion devices, receiving data and status information from the devices, generating and viewing reports, adjusting device settings, viewing historical maps showing device performance; receiving alerts, configuring alert triggers, observing and editing schedules and scent profiles, observing unitless parameters for articulation and display of scent levels, reviewing alerts to replace packages, ordering and paying for new packages, rescheduling subscription for scent management services, reviewing system health (e.g., machine downtime alerts), changing licensing rights for users, initiating tickets/workflows, assigning service technicians, adding or removing devices from a network, and adding customers/departments/stores. A mobile application may be used to access the user interface. The user interface may further comprise a scheduling facility to indicate when a service is scheduled to occur in the environment and to allow the user to select a scent complementing the scheduled service to be diffused in the environment. The alert may be based on various criteria and configurable conditions (e.g., low liquid, machine shut down, etc.). The arrangement and odor distribution can be observed and edited independently of one another for one or more diffusion devices. Adjusting the diffuser settings may involve the user increasing or decreasing the total output of all diffusers in the location and allowing the NOC to calculate and adjust the settings of each diffuser needed to achieve the total location volume setting.
In one aspect, a method of managing scent in an environment can comprise: providing one or more scent diffusion devices within an environment, wherein the scent diffusion devices include a communication facility that enables transmission and reception of signals to and from a remote computer; receiving at least one scent parameter at a remote computer for scenting an environment; and controlling at least one of the scent diffusion devices to achieve the scent parameter by the remote computer. Controlling may include adjusting an operating parameter of the scent diffusion device in response to a sensed scent level in the environment.
Referring to fig. 9, a method for operating an atomizing diffusion device within an environment may include: receiving at a computer level data from a plurality of remote atomizing diffusion devices, wherein each diffusion device comprises a communication facility enabling transmission and reception of signals to and from the remote computer and at least one level sensor; and creating, by the remote computer, an electronic data structure characterizing the transition of the remote diffusion device based on the liquid level data 902, wherein the electronic data structure includes data specifying at least one of: production of flavor, procurement of flavor, management of flavor inventory, delivery of flavor inventory 904; and causing a remote atomizing diffusion device to perform the transition 908.
In another aspect, a method of managing scent in an environment can comprise: one or more scent diffusion devices are disposed within the environment, wherein the scent diffusion devices include a communication facility that enables transmission and reception of signals to and from a remote computer. The method may further comprise: providing at least one sensor within an environment, the at least one sensor transmitting sensor data to a remote computer; and receiving at least one scent parameter at the remote computer for scenting the environment. The method further comprises the following steps: diffusion of a liquid from a source of the liquid in fluid communication with at least one of the scent diffusion devices to achieve a scent parameter is controlled by a process computer. In embodiments, not diffusion of a liquid but diffusion of a gas. The controlling may comprise setting or adjusting an operating parameter of the scent diffusion device in response to the sensor data. The sensor data may relate to static parameters or dynamic parametersSuch as room volume, room geometry, room area, air flow, presence of odor-generating substances, presence of odor sink factors, lighting, air flow, altitude, traffic volume, occupancy detection (e.g., IR, camera, CO) 2Sensors), proximity sensing, detected odor, scent level, scent concentration coefficient, temperature, humidity, time of day, season, weather event, detection of VIP/specific individual entry into a space such as by smart phone ping, etc. In certain embodiments, the odor diffusion device may be configured to a baseline configuration at installation based on static parameters of the installation site. The device will then intelligently adjust the scent output based on an algorithm that adjusts for dynamic parameters or time-varying conditions. Some static parameters include room volume, room geometry, room area, and altitude. With respect to the room volume, a volume calculation may be performed based on measurements made of the room using, for example, a tape measure or a laser rangefinder, and then the volume data added to a data structure characterizing the space in which the diffuser is deployed. This may be done at the time of installation of the device to establish a reference setting for the odour concentration coefficient. With respect to the room geometry, the geometry may be determined by taking into account the entrance area, the exit area and other areas where people move and from the floor plan. The room area may be calculated based on sensor measurements of the linear distance between the walls. With respect to altitude, based on cell phone technology, a diffusion device may have proximity detection capabilities, which allow the device to "know" where it is located, e.g., at a particular longitude and latitude. In view of the longitude and latitude information, the networked device may query a remote database for the specific altitude at which it is located. This altitude information is then used to adjust the device performance such that, for example, a lower setting of odor diffusion will be used at high elevations where the air is "rarer" and a higher level of odor diffusion will be used at lower elevations where the air is "thicker".
The dynamic data includes: presence of odor-generating substances, presence of odor sink factors, lighting, air flow, traffic volume, occupancy detection (e.g., IR, video camera, CO)2Sensor), proximity sensing, detected odor, scentTaste level, odor concentration factor, temperature, humidity, time of day, season, weather event, detection of VIP/specific individual entry into a space, etc.
With respect to air flow, sensor technology can measure the mass of air flowing through a device (typically a tube) per unit time. The air flow sensor may be a differential flow or pressure sensor or a switch or transducer. For a fixed airflow HVAC system or PTAC system, the airflow sensor may be in the form of a switch that indicates whether airflow above a certain threshold is present. The information will be used to "turn on" the scent diffuser when air is flowing and to "turn off the scent diffuser when air is not flowing. For a variable airflow HVAC system or PTAC system, the airflow sensor may provide an analog voltage reading that indicates the actual level of airflow. This analog signal can be used to automatically adjust the diffuser output based on the level of air flow. In this way, the device is able to enhance odor diffusion when air flow is high and reduce odor diffusion when air flow is low (or stop odor diffusion when air flow is "off)
With respect to the presence of odor-generating materials, semiconductor sensors may identify airborne odor particles, where such sensors may be "tuned" to a particular odor. The receptors of these sensors may be able to identify the shape of the scent molecules, or alternatively, be "tuned" to a certain quantum effect of the scent molecules (such as their vibration level). Based on the detection of certain known odors within the environment, the diffusing device may change its level or odor, or conversely a second odor management or neutralization diffusion may be added, thereby counteracting the odors. In the case of a dual cartridge system, one cartridge contains the desired flavor fragrance and a second cartridge contains the odor management agent/neutralizer, which will diffuse according to a preprogrammed response upon detection of a particular odor.
With respect to the presence of the off-flavor sink factor, certain types of molecules will interact or bind with the odor particles, causing them to exit the cycle. These odor sinkers can be identified in much the same manner as previously described for malodors, allowing the diffusion device to follow a pre-programmed algorithm in response to the presence of odor sinkers.
With respect to illumination, a photodetector is a device that can sense the presence of photons. There are a number of well-known and commercially available techniques to enable photon detection, and some of them are also "tuned" to detect and measure the relative amounts of certain types of photons, which have characteristic wavelengths (red, blue, etc. in the visible spectrum). The diffusion device has a data input that enables the diffusion device to respond to detection of light or absence of light, such as to turn off scent diffusion when light is not detected. Similarly, lighting systems in stage production may be used to control the odor diffusers such that the networked odor diffusers will follow the programming direction of the lighting control system.
With respect to passenger flow, a people detector is a sensor that can count the number of times a person has walked through a particular point. One type of detector is a photosensor that detects the number of times a light beam placed across a space is interrupted or interrupted by a walking person. Another type of detector is an image or video camera that uses image processing techniques to determine the number of people in a space and the dwell time of their individuals. The diffusion device can take information from the passenger flow sensor and automatically adjust its scent diffusion, for example by scenting the area or increasing the scent level to accommodate larger passenger flows when a person arrives.
With regard to occupancy detection, these sensors may confirm the presence of one or more individuals within the space. One approach includes image or video cameras that use image processing techniques to determine the number of people in a space and the dwell time of their individuals. The diffusion device may take the occupancy related information and automatically adjust its scent diffusion, e.g. by providing more scent to more areas of the person or stopping the scent diffusion in free rooms and then starting to diffuse the scent when the person arrives.
With regard to proximity sensing, a proximity sensor is triggered when a person is directly in front of a particular space, such as in front of a particular product display. By sensing the presence of a person in the space, the diffuser can provide a scent experience that is coordinated with the presentation of the product in the display.
With respect to the detection of VIP/specific individual entry into the space, a camera with facial recognition software may determine the presence and identity of one or more individuals whose facial contours have been preloaded for comparison. In another embodiment, the VIP/specific individual may be detected by detection of their smart phone. The presence of a particular person can thus be communicated from these sensors to the device, allowing the scent diffusion device to modify its performance.
With respect to fragrance levels, by "tagging" a desired flavour perfume with molecular tags (such as charged particles), the sensor may be able to identify and determine the concentration of "tagged" odour particles within the space. The diffusion means may be arranged to deliver a certain level of scent concentration within the environment and, using the detection of an off-note to the scent particles being dispensed by the diffuser, a defined range of acceptable scent levels or "scent concentration factor" or SCF may be ensured. When the sensor detects a concentration of the odor below the desired SCF, then the diffuser delivers an additional phase to achieve the desired concentration. If the measured concentration is within the defined SCF, the diffuser continues to monitor without diffusing. If the concentration is above the SCF, the diffuser may continue to monitor without diffusion, or may diffuse the odor precipitation formulation in combination with the airborne odors, thereby reducing the odor levels to the desired SCF range.
With respect to temperature, the odor diffuser may have a variety of ways to measure temperature. The internal temperature within the diffusion device is measured using a thermistor present in the electronics of the device. This thermistor allows the device to communicate the internal temperature to a remote monitoring center, which may be alerted if the internal temperature exceeds a prescribed threshold (such as the recommended operating temperature range of the device). Similarly, with remote monitoring, the device may be pre-programmed to take some action under certain temperature conditions, such as stopping dispensing scented oil if the temperature is above its operating threshold or below the freezing point of scented oil. The external temperature may be measured based on a thermal sensor (thermistor) mounted on the exterior of the device, allowing the diffuser to alter its performance based on changing temperatures within the environment. The temperature of the outside climate may be retrieved from a remote data structure based on its geocoded location using the network connectivity of the device. The diffuser may react to the external ambient temperature by diffusing the substitute fragrance or by modifying the concentration of the fragrance. With all three forms of temperature measurement and using the remote monitoring capability of the device to track data across the diffuser, one can determine statistical correlations of temperature with other performance trends (e.g., rate of oil consumption over time).
With respect to humidity, a humidity sensor installed within the device may detect the internal device humidity, a humidity sensor on the exterior of the device may determine the ambient humidity within the space where the scent is being dispensed, and a geocode and remote data lookup table may be used to retrieve the humidity of the local climate. The scent device may react to these changes in humidity levels similar to that described for temperature. Similarly, over time, remote monitoring may be used to assess and correlate trend data, such as how humidity affects the rate of consumption of scented oil within the diffuser.
Regarding the moment, the diffuser is an intelligent, connected device and, therefore, the time is accurately known. Based on the geographical location data (or network id) from the handset modem of the diffuser in the scenting environment, the device can accurately set its clock to the correct local time zone and automatically adjust for the full seasonal adjustment of time, with the goal of keeping the diffuser unit time synchronized with the world clock. Since the scent diffuser device has the ability to change scent output or scent type based on the scent program or playlist, it is critical for the device to have an accurate representation of its current time.
Regarding the season, the diffuser has the ability to tell the time exactly and know the current day, week and year using the same approach as described above. Using this knowledge of time, the diffuser may be programmed for different performances on different dates or in different seasons of the year.
With respect to weather events, since the diffuser is intelligent and connected, local weather conditions may be downloaded to the device based on the geographic location of the device. Based on these local weather conditions, the diffusion device may alter its performance based on a set of predefined rules.
The scent diffusion device can include at least one package containing scented oil or at least two packages containing scented oil. In an embodiment, one of the scent diffusion apparatuses is a master node, and the other scent diffusion apparatuses are slave nodes and receive control instructions from a computer via the master node. In this embodiment, each scent diffusion apparatus may adjust its own control settings based on the activity of the other scent diffusion apparatuses. The method may comprise: the scent diffusion devices are configured such that a device duty cycle of one of the scent diffusion devices occurs at or not near the same time as another of the scent diffusion devices. The odor parameters may be related to brand management goals. The method may further comprise: based on determining the total number of scent diffusion devices to be provided in the environment. The method may further comprise: one or more locations in the environment where the scent diffusion device is to be located are determined based on the room volume. The operating parameter may include at least one of: flow rate of the liquid, duration of flow of the liquid, change in flow rate of the liquid, on/off state of the diffusion device, package from which the liquid is diffused, switch to different packages from which the liquid is diffused, etc.
In another exemplary use scenario, the scent dissemination network comprises one or more scent node devices and a wide area network gateway device. In this scenario, the network gateway device performs the communication and control functions of the scent gateway device without actually distributing the scent. In this scenario, a system administrator in the NOC controls the programming of all networked scent devices and ensures that the scent dispersion meets commercial brand standards or other parameters. This scenario provides remote and centralized management of the scent dissemination network through a network gateway device that does not dispense scents.
In one aspect, a method of managing scent in an environment can comprise: one or more scent diffusion devices are disposed within the environment, wherein the diffusion devices include a communication facility that enables transmission and reception of signals to and from a wide area network gateway device that does not dispense scents. The method may further comprise: a network gateway device is networked to the scent diffusion devices, wherein the network gateway device receives communication and control functions from a remote computer for distribution to the scent diffusion devices. At least one sensor disposed within the environment may transmit sensor data to a remote computer. At least one target value for an odor parameter of the environment may be received at a remote computer. The method may further comprise: controlling, by a remote computer, diffusion of a liquid from a source of the liquid in fluid communication with at least one of the scent diffusion devices to reach a target value of a scent parameter, wherein controlling comprises setting or adjusting an operating parameter of one or more of the scent diffusion devices based on sensor data. In embodiments, not diffusion of a liquid but diffusion of a gas. At least one of the scent diffusion devices receives control instructions from a remote computer and relays the control instructions to at least one other scent diffusion device. The scent diffusion device may relay control instructions in series, in a ring, in a grid, in a star networking topology, and the like.
In another exemplary use scenario, the scent distribution network includes one or more scent node devices, one local area network control device, but no wide area network gateway device. Each scent node device is paired with a local area network control device, which enables local users in the venue to program and control the scent node device independently of the NOC (as opposed to a centralized, remote controlled, local control). This scenario enables management of the scent dissemination network through a wireless local area network communication protocol. Examples of local area network control devices include computers or laptops with wireless local area network communication capability; a smartphone, pad device, or tablet computer with wireless local area network communication capabilities; or a purpose-built scent controller device with wireless local area network communication capability. In embodiments, the scent controller device may be a handheld or wall-mounted device for controlling one or more networked scent diffuser devices.
In one embodiment, a method of managing scent in an environment can comprise: providing at least one scent diffusion device within the environment, wherein the at least one scent diffusion device includes a communication facility that enables transmission and reception of signals to and from an independent remote control device; receiving at least one target value of a scent parameter of an environment at an independent remote control device; and controlling, by the independent remote control device, the diffusion of liquid from a source of said liquid in fluid communication with at least one odor diffusing device, based on the target value, to reach the target value of the odor parameter. In embodiments, not diffusion of a liquid but diffusion of a gas.
In one aspect, a method of managing scent in an environment can comprise: providing one or more scent diffusion devices within the environment, wherein the diffusion devices include a communication facility that enables transmission and reception of signals to and from the local area network control devices; and networking a local area network control device to each of the scent diffusion devices, wherein the local area network control device receives communications from and distributes control instructions to the scent diffusion devices. The method may further comprise: providing at least one sensor within an environment, the at least one sensor transmitting sensor data to a local area network control device; receiving at least one scent parameter at a local area network control for scenting an environment; and controlling, by the local area network control device, diffusion of a liquid or gas from a source of said liquid in fluid communication with at least one of the scent diffusion devices to reach the scent parameter, wherein controlling comprises setting or adjusting an operating parameter of one or more of the scent diffusion devices in response to the sensor data. The local area network control means may comprise one or more of: a computer or laptop with wireless lan communication capabilities, a smartphone, pad device, or tablet with wireless lan communication capabilities, a purpose-built scent controller device with wireless lan communication capabilities, a handheld device, a wall-mounted device, and the like.
In yet another exemplary use scenario, the scent dissemination network comprises one or more scent node devices without a wide area network gateway device and a local area network control device. This scenario provides for independent operation of the scent node means using manual settings established by the local individual using a user interface found on each scent dispersion means.
In an embodiment, multiple master devices may be deployed at a single physical location. In embodiments of a multi-device installation (master-slave configuration), each device may adjust its own control settings based on the activities of the other devices. For example, if one of the diffusion devices fails, is blocked, shuts down unexpectedly, or otherwise ceases operation, status or alerts may be broadcast to other diffusion devices, gateway devices, NOCs, or some other recipient on the network by the device itself or another occupant in the network that is unable to receive a response from the device. In response, one or more neighboring networked devices may automatically reconfigure their diffusion parameters, or may be reconfigured remotely or by a master diffusion device, to compensate for the loss of the diffusion device. The system may be a coordinated device network having a "local scent network" level control mechanism as opposed to a device independent control mechanism. For example, a group of grid-tied (meshed) dispensers may be configured such that the individual device duty cycles do not occur at approximately the same time as one another (one device waits for the previous device to dispense so they do not ultimately "trigger" multiple scent devices at the same time to overload an area). Of course, they may also be configured to trigger at the same time. In effect, coordination, sequencing and/or synchronization of the grid-connected scent devices is dynamically controlled. In one example, the reservoir level of the device can be automatically balanced, if possible, such as by automatically adjusting the duty cycle to level it so that both tanks are depleted simultaneously.
In another example, if a device fails and another device or devices must be adjusted (e.g., output/speed/voltage) to replace the fragranced output of the failed device, then all of the devices or systems may appear as one system on the user interface. The user may see a low priority warning that shows one pump is not functioning, but the system is compensating with a second pump. The user does not see the scenting effect and can receive a warning that they will need service access.
In one embodiment, the number and location of scent diffusion devices within the enclosed space may be established based on the volume of the space, but the individual control programs for these devices may be based on things outside the volume of the space, such as sensor readings, area, linear distance of the device to the target, and the like. In an embodiment, the initial setting of the diffusion device may be established in one way (such as by using room volume), but may then be over-transformed to be controlled by a different mechanism (such as by environmental adjustments or consumption rate measurements, etc.).
In one embodiment, the diffusion device operates in a scent burst mode, wherein the device is programmed with a linear distance to a scent target location and a level of scent that should be at the target location. Other considerations may include air flow when programming the scent spray mode and cooling capacity (tonnage) of the HVAC system or PTAC system. In the scent dispensing mode, the target does not fill the space with scent, but rather fills the target area with scent or smells it by the audience to create a scent brand impression.
In one aspect, a method of emitting a scent in an environment can comprise: providing a scent diffusion apparatus within an environment, wherein the scent diffusion apparatus includes a communication facility that enables transmission and reception of signals to and from a remote computer; determining a distance from the scent diffusion apparatus to the scent target location; receiving at least one scent parameter of a scent target location at a remote computer; and controlling, by the remote computer, the scent diffusion apparatus to achieve the scent parameter, wherein controlling comprises setting an operating parameter of the scent diffusion apparatus based on the determined distance and the scent parameter. The method may further comprise: providing at least one sensor within an environment, the at least one sensor transmitting sensor data to a remote computer; and adjusting an operating parameter of the scent diffusion apparatus in response to the sensor data. The sensor data may relate to at least one of: room volume, room geometry, room area, air flow, presence of odor-generating materials, presence of odor sink factors, lighting, air flow, altitude, passenger flow, occupancy detection (e.g., IR, camera, CO2 sensor), proximity sensing, detected odor, fragrance level, temperature, humidity, time of day, season, weather event, and detection of VIP/specific individual entry into a space (via smart phone ping, etc.). The method may further comprise: adjusting an operating parameter of the scent diffusion device in response to the HVAC coldness or the PTAC coldness.
Sparging of odours in the environment may be achieved using diffusing means, such as a network of odour diffusing means. A network of diffusion devices may be disposed within the environment, each diffusion device including a communication facility that enables transmission and reception of signals to and from remote computers. One such received signal may be a scent parameter of a scent target location. The distance from the diffusion device to the scent target location may be determined by any means that is available for such determination. By means of a remote computer, the network of diffusion devices can be controlled to reach the odor parameters. Controlling may include setting an operating parameter of the diffusion device based on the determined distance and the odor parameter.
Odor emission can also be performed using hot spots in the environment. Such a diffusion device may include: a sensor to determine a distance from the diffusion device to the scent target location; and a first communication facility 1022 which receives control signals from the network operation center for controlling the diffusion of scent from the diffusion device according to the scent impression target and the distance. The device may also include a second communication facility 1024 to communicate data with a mobile device at the scent target location for customer interaction (consumer interaction), such as providing coupons, advertisements, surveys, games, or other content to the customer.
In embodiments, the scent spray may utilize a diffusion device that creates a vortex of air (such as a circular vortex of air) that may include the scent to be diffused. The vortex of air containing flavour particles may remain substantially coherent as it passes through a larger air space, such as in a room, like a smoke ring. The air vortex generator or vortex cannon may be integral with the device or located separately from the device, but in a location suitable for emitting odors from the device, such as enclosing the device within the vortex cannon. The vortex cannon may be activated in an automated manner to emit the diffused scent in a desired direction, such as toward a target location. For example, when motion is sensed in an area such as a guest-receiving area of a restaurant venue, the vortex cannon may be activated to deliver a burst or dose of scent to the area. Similarly, the vortex cannon may be triggered by opening an entry way, by a timer (such as releasing a scent at the time of an event), or by a user interface (such as a button or remote control).
The ticketing and workflow facilities of the NOC may receive alerts and generate tickets from the device management and monitoring system. The ticket may be passed to the correct person based on the rule, or in some cases, the rule may automatically trigger some action (e.g., shut down a poorly performing device, or restart the device). The ticketing and workflow facilities may be configured versions of the business service ticketing system.
Managed networked diffusion devices (where the device is unaware of the actual diffusion technology) may be used to produce consistent odor distribution in a wide area/ambient environment according to brand standards or other parameters. In one embodiment, generating a consistent odor profile involves consistently neutralizing the odor in the environment. Generating a consistent odor profile may include management of: duty cycle, schedule, fragrance level/perfume refill, room volume, room geometry, air flow, presence of odor-generating materials, presence of odor sink factors, lighting, temperature, humidity, altitude, passenger flow, occupancy, time of day, inventory of particular "base", "medium" and/or "high" levels in the fragrance profile, and other variables related to the environment. In this way, data collected by or about the device, data based on measurements made by sensors on or associated with the device, and data from the user may be transmitted to, generated by, or used by the NOC for ease of management. These data will be described herein.
Certain data types may be transmitted from the diffusion device to the NOC or other user. Data about the work schedule, such as duty cycle, time slice (day part), etc., may be sent by the diffuser. An object type such as the type of diffuser (e.g., master, slave, independent) may be emitted by the diffuser. The diffusion device may emit a scent name and a scent level. For example, the scent level may be a value of 0 to 100, where 100 is full and 0 is empty. Temperatures in degrees fahrenheit, celsius, or other units, as well as dates and times may be transmitted. The flooding device may send an indication of the local wireless link strength. Any error code arrays currently present on the device may be transmitted. The diffuser may emit an average pump pressure.
The diffusion device may report diagnostic data on a periodic basis, such as weekly/daily, or by forcing the diffusion device into a diagnostic mode, such as through a local keypad or controller or from the NOC. The master device may report data usage, such as cellular data usage.
In one embodiment, a device management and monitoring (DM & M) facility may be embodied in a user interface that may include a configurable dashboard to enable activities such as viewing diffusion device telemetry data, viewing a map of diffusion device locations, receiving liquid level readings or other meter/sensor readings, providing control instructions to the diffusion device, reviewing the status of one or more networks of odor diffusion devices and managing its odor operation, receiving data from the device, receiving alerts, viewing/editing schedules and odor distribution, viewing unitless parameters for articulation and display of fragrance levels, reviewing alerts to change packages, ordering new packages, and paying online; subscription to scent management services, consulting system health (e.g., machine downtime alerts), changing user's licensing rights, initiating tickets/workflows, assigning service technicians, adding or removing devices from the network, and adding customers/departments/stores, etc. In an embodiment, a mobile application, such as a smartphone or tablet application, may allow a customer to access a mobile version of the user interface. In an embodiment, a mobile application, such as an installer application, may be used to assist in installing a device, including setup, installation, activation, and management. The mobile application may need to interface with the NOC to receive one or more codes that verify the authenticity of the installation.
The user interface may be used to set and trigger alerts based on various criteria and configurable conditions (e.g., low liquid, machine downtime, etc.), where the NOC exceptions may be based on the detected alarm management system. The user interface may allow customers to view the status of their diffusion devices, adjust their settings, or view historical maps showing the performance of the devices. The user interface may take data from the DM & M and present the data in a language that uses the scent rather than the language of the device (e.g., MAC address, PAN number). In an embodiment, the DM & M facility may be responsible for all communications with the diffusion device and may be the only module that may change the settings of the diffusion device. In other embodiments, WiFi capability may be included in the primary diffusion device, enabling direct connection to the device.
The user interface may be used to manage and edit the arrangement of one or more diffusion devices independently of each other. That is, different diffusers at a single site can have different arrangements.
The report page may be used to generate and access reports. The "about page" or introductory page may tell the user about the version number of the application, as well as the version numbers of the various devices and the device type.
The user interface may include a login screen for entering and authenticating a user ID and password for the user. The user interface may include a dashboard page that shows the status of all local diffusion devices at a general level. A visual icon may be included in the dashboard to represent each diffusion device with an indicator for function or status. The user interface may include a diffusion device page that includes a list of diffusion devices at the location and summarized states and settings (e.g., volume settings, overall diffusion device health, whether a diffusion device is currently diffusing based on duty cycle, communication link status, etc.). An icon for each diffusion device may be presented. The diffuser status page may be a drop-down page showing all device status data and settings, such as overall diffuser health (good, or error + error code and description), diffuser volume/output level settings (according to a program), diffuser volume/output level settings (according to settings made by a local customer that may override a program), liquid fragrance levels (based on sensor readings), time and date according to the device clock, health of the communication links between the various devices and the local server, which fragrance is being ejected/diffused in the diffuser, date and time of last service, and so forth. The edit diffuser settings page may be a page in which the user can edit the settings of the diffuser and save the new settings, including the on/off program settings and the fragrance volume level.
The position control page may allow the user to increase or decrease the total output of all of the diffusion devices in the position. For example, an algorithm, such as a position control algorithm, may perform a calculation that converts a target scent value (also referred to as a local output level) in the position (e.g., between 0-100, between 0-10, etc.) into an actual device setting for each diffusion device. The user will only adjust the total location volume setting and not the setting of each diffusion device. The NOC will then calculate and adjust the settings for each diffusion device needed to achieve the total positional volume setting. The local output level represents the output level aggregated across all diffusers. The user interface may present graphical arrows for moving the output level up or down. The master diffusion device may proportionally adjust its own output level up or down based on the new setting and the output level of its slave devices. If all of the diffuser settings are the same, then the new settings will all be the same, but if the diffusers have different output settings, then the new settings may be adjusted based on the original settings for each diffuser. As an example, the current output level may be 70 based on 3 diffusers whose outputs are set to 65, 70, and 75. If the user moves the output level to 80, the new setting may be the original setting multiplied by (80-70)/70, resulting in 74.28, 80, 85.71 settings, respectively. The above calculations may be made by the customer web service or NOC and pushed to a separate diffuser.
The position control algorithm, when calculated, may include feedback from one or more sensors in the environment or on the diffusion device, such as feedback from: bluetooth/WiFi sensors (e.g., to determine occupancy), different occupancy sensors, altitude sensors, air flow sensors, humidity sensors, light sensors, motion/occupancy/proximity sensors, laser rangefinders/digital laser rangefinders, particle sensors, olfactory sensors/VOC sensors, imaging sensors/cameras, odor concentration coefficient sensors, clocks, timers, calendars, weather sensors, and the like. The modification or generation of the scent distribution delivered by the network of scent diffuser devices may be based on one or more sensed parameters, where modifying the scent distribution is performed by selecting or adjusting diffusion settings for one or more available fragrances on one or more of the networked scent diffuser devices. The sensed parameter may be at least one of: room volume, room geometry, room area, air flow, presence of odor-generating materials, presence of odor sink factors, lighting, air flow, altitude, passenger flow, occupancy detection (e.g., IR, camera, CO2 sensor), proximity sensing, detected odor, fragrance level, temperature, humidity, time of day, season, weather event, detection of VIP/specific individual entry into a space (via smart phone ping, etc.), and the like. In embodiments, the odor profile is neutralization of malodors and the fragrance comprises odor neutralizer. The modification or generation of the odor distribution delivered by the network of odor diffuser devices may be based on feedback from an automated air sampling, where the modification is by selecting or adjusting diffusion settings for one or more of a plurality of available odor modulators on one or more networked odor diffuser devices. The user can adjust the overall fragrance level desired in the space, and the NOC or master diffuser device can determine the adjustment required for one or more devices, such as slave diffuser devices. The master diffuser device may proportionally adjust its own output level up or down based on the new settings and the output level of its slave devices. In one embodiment, the automated air sampling can be automated odor sampling and identification, the odor distribution can be neutralization of odor, and the odor modulator is a neutralizing agent or fragrance. Adjusting the settings may include selecting the most appropriate neutralizing/fragrance for treating the malodor and determining and performing the distribution of neutralizing agent/fragrance distribution needed to neutralize or counter the malodor.

In one embodiment, a sensor may be used to gauge the scent level of an environment to provide feedback to a network of scent diffusion devices in order to continue to produce a consistent scent distribution over a wide area. In embodiments, this feedback enables the scent management system to operate in a closed loop manner. The sensor may be one or more of the following: particle sensing, olfactory sensors/VOC sensors, odor concentration coefficient (SCF) sensors, sensors measuring agents/tags dispersed with fragrance, sensors measuring electrostatic charge, etc. For example, the scent may be mixed with a tracer for diffusion into the space through one or more networked scent diffuser devices, where the tracer may be tracked throughout a broad area.

In an embodiment, determining the liquid level inside the package may be accomplished using a floating magnet and at least one hall effect sensor or hall effect switch disposed outside the package. Voltage data acquired at each hall effect device can be used to determine the position of the floating magnet within the package. For example, the level sensor may include: one or more hall effect sensors or switches disposed on the level sensor plate 2412, such as on a line, on a track, etc.; and a magnetic float 2320 that moves as it floats at the liquid level inside the reservoir of the package. As the magnetic float 2320 moves along the cartridge float guide 2318, it passes one or more sensors or switches in the liquid level sensor plate 2412. Each sensor or switch outputs a voltage in response to the magnetic field from the magnetic float 2320. The magnetic field strength decreases exponentially with distance, so the closer the float is to the sensor or switch, the higher the magnetic field and the higher the output voltage will be. The output voltage is therefore a function of the distance between the hall effect sensor/switch and the magnetic float. Furthermore, the functions typically follow relationships such as gaussian relationships, coulombic relationships, exponential relationships, or higher order polynomial relationships. The examples herein may rely on a gaussian relationship, but it should be understood that other functions may describe such a relationship. When the float is directly adjacent to the hall effect sensor/switch in the liquid level sensor plate 2412, the output voltage may be at the apex of the gaussian curve, and as the magnet moves away from the sensor/switch, the output voltage may drop in a gaussian relationship as it approaches zero. Thus, for each incremental distance from the sensor/switch, the sensor/switch outputs a unique voltage. Since the gaussian relationship of the voltage output and the distance from the hall effect sensor/switch is known in advance for each hall effect sensor/switch, determining the distance of the magnet from the sensor/switch can be as simple as determining where the output voltage falls along a gaussian curve, such as by using a computer or processor that receives the output voltage from the hall effect sensor/switch. In embodiments, the height of the functional curve may depend on slight inconsistencies in the structure of the plastic molded parts used in the device. The processor may identify and consider inconsistencies.
Referring now to fig. 25, the graph depicting the% fill of the cartridge (fill fraction) is based on readings from six sensors (sensor 1, sensor 2, sensor 3, sensor 4, sensor 5, and sensor 6). At each fill fraction, there is a different reading (e.g., in millivolts) from each sensor due to the positioning of the sensor. At a given fill fraction, the voltage of each sensor is observed. If the magnet at the top of the liquid is a point, then using coulomb's law, for each sensor, a function of the millivolt reading of the sensor as a function of the fill fraction is expected to have the following form:
wherein sensor (mV) is the sensor reading in millivolts; f is the fill fraction; x is the fill level at which the sensor gives its maximum reading; vMinimum sizeIs the minimum (background) reading of the sensor. In fact, the magnet is not a point, nor is it precisely located at the top of the liquid.
Furthermore, the limited size of the magnet does not allow it to float at its natural position in the liquid when the filling level is close to empty or close to full. The latter can be seen from the horizontal point 2502 of fig. 25 close to a filling amount of 0.00 and the horizontal point 2504 of fig. close to a filling amount of 1.00. Looking at the data plot, one realizes that the voltage reading at the minimum cannot distinguish between fill levels. Only in which the voltage reading is above maximum Within a small value of the fill fraction, the voltage provides information about the fill fraction. For the reasons described above, for each sensor, a curve may be fitted in the region where the sensor reading is above some selected minimum. When fitting this curve for each sensor, k1, k, X, e, and V are estimatedIs low in. For each sensor, a curve fitting function can be used to take the data as input and calculate k1, k, X, e, and VIs low inIs estimated by least squares. The curve may have the form shown in equation 1:
equation 1:
fig. 26 depicts the fitted curve along with the data from table 3 for the fit. The data used to estimate the fill fraction is the voltage readings from the various sensors. An example of such a set of readings is shown in table 1.

The plots for the readings shown in table 2 are depicted in fig. 27 using curves estimated by curve fitting functions. From a single sensor curve, the voltage can give two possible fill levels along the curve: a high value by using a plus sign in equation 2 and a low value by using a minus sign in equation 2. Visually, the correct estimate here is about 0.58 based on all three observed voltages. As for the algorithm, the estimation algorithm may first choose for each sensor curve the area to the right or left of its maximum and then choose the inverse function to evaluate, filling the fraction f (sensor voltage). The cases around 0.0 and 1.0 may be more complex, but the cases are similar. The values of the best fit for each sensor curve may utilize the constants shown in table 3:

The inverse function (i.e., fill fraction ═ F) as a function of sensor reading S is shown in equation 2.
Equation 2:
a plus sign is used if the region is to the right of the peak of the curve, otherwise a minus sign is used. This selection is based on the values of the other sensor readings. If the term in the absolute value is negative, it is set to zero. The equations for each sensor are slightly different because the parameters are different. For example, in the case where only S1 or S6 is to be used, F is estimated using a minus sign in equation 2 for S1, and a plus sign for S6. In another example, where there are two adjacent sensor readings to be used, for the sensor closest to the top of the cartridge (e.g., the "higher" sensor, S2), a minus sign estimate F is used to give an S2 low value, for the "lower" sensor (e.g., S3), a plus sign estimate F is used to give an S3 high value, and the two calculated values are averaged together as an estimate of F. In some embodiments, the average is used only when the calculated values are within 2% of each other. If they are not within 2%, then the values are not averaged and one of the values is selected to represent the fill fraction, as described below.
In one example, a method for determining a fill level includes using an algorithm that takes several steps. In a first step, sensor voltage readings below a certain threshold are discarded. In a second step, readings that differ from the maximum sensor voltage reading by more than a threshold number of standard deviations are discarded. The maximum sensor reading indicates the sensor closest to the magnet. This is achieved by: the standard deviation of all sensor readings is calculated and then it is determined whether each sensor reading is within a threshold amount of standard deviation from the maximum reading. This can be done by: the threshold number of standard deviations is multiplied by the standard deviation and the result is added to the sensor voltage reading. If the result of this calculation is greater than the maximum voltage reading, the individual sensor reading is discarded. In a third step, and as described herein, equation 2 may be used to calculate the% fill. Each sensor has two% filled possible values: "high" obtained using "add k" in the formula, and "low" obtained using "subtract k" in the formula. These represent the left and right sides of the peak of each sensor curve. In a fourth step, by observing the "slope change", it can be determined from which side of the sensor curve the voltage reading came. This is done by first determining whether the% fill falls between the high% clip (clip) value and the low% clip value. Above the filled high% segment and below the filled low% segment, the previous reading minus the average usage of the device should be taken as the predictive model. Each calculated fill% (both high and low) of the sensor is evaluated to determine if it falls within the high and low segment values. If the particular% filled value falls between the high and low segment values, the calculated% filled is compared to the% filled value calculated for the immediately preceding voltage reading, and if the calculated% filled is less than the% filled calculated for the immediately preceding voltage reading, the calculated% filled is considered a valid reading. In a fifth step, the valid readings for each sensor, i.e. both the high and low values for each sensor, are aggregated. For example, for a particular cartridge, at a single sensor, there may be a series of four valid readings on the high side, followed by four invalid readings on the high side, based on eight consecutive decreasing fill levels. For the same eight consecutive decreasing fill levels, the complementary readings on the low side may be four invalid readings followed by four valid readings. In this example, the remaining readings at various fill levels of the cartridge are invalid at this sensor. Thus, for this sensor, there are eight valid readings, the first four valid readings on the high side followed by the next four valid readings on the low side. These eight valid readings are used to determine the calculated% fill of the box in the subsequent steps. In a sixth step, a final determination is made of the calculated% filling of the box. In the high segment range, the predicted calculated% fill drops from 100% at an average rate determined based on a weighted average of historical usage (in ml/hour pump run time). Once below the high segment threshold, the% fill is calculated based on the valid readings of the box until the low segment threshold is reached. If there is only one% calculated fill for a particular fill level, that value is used. When two or more adjacent sensors have valid readings for a particular fill level, the calculated% fill determined for each sensor is averaged to arrive at the final% fill of the box at that fill level. Once the low segment threshold is reached, the average depletion rate is used to calculate% fill from the last valid reading.
In yet another example, where there are three sequential sensor readings to use, for the "highest" sensor (e.g., S2), F is estimated using a minus sign to give an S2 low value, for the "lowest" sensor (e.g., S4), F is estimated using a plus sign to give an S4 high value, and if the "highest" sensor (S2) voltage is greater than the "lowest" sensor (S4) voltage, for the "middle" sensor (S3), F is estimated using a plus sign to give an S3 high value. Otherwise, a minus sign is used for S3 to give an S3 low value. Then, all three calculated values are averaged together as an estimated value of F.
In an example using the data in table 2, for S2, a minus sign and F ═ 5835 are used, for S4, a plus sign and F ═ 5869 are used, and for S3, since S2 ═ 2546> S4 ═ 2470, a plus sign and F ═ 5830 are used. Averaging these together, the estimate of F is.5844, and thus, the cylinder fullness is estimated to be 58.44%.
In an embodiment, to determine the fill score when the box is mostly full or mostly empty, for each sensor reading, a plus sign and a minus sign may be used in two separate calculations to give the sensor high and sensor low fill score calculations for that sensor, and then rules are used to determine the actual fill score. In this embodiment, each device may calculate and store its rolling "average usage of pump run time per hour" (R/PRT) in milliliters per hour. This calculation result may also have a time stamp to confirm its recency. If the device is unable to calculate the R/PRT for more than 48 hours, an alert may be generated. The rolling average calculation may be based on a 24 hour period to obtain an average across a "segmented by day" schedule. The sensor high/low value (S/HL as% full) can then be calculated using the constants in equation 2 and table 3. Constants (k 1, K, X, V low and e for each sensor, such as 30 constants in table 3) may be retained in the device firmware. In embodiments, the constant may be unique for each diffuser, or may be constant for all diffusers. In an implementation, constants may be updated on the device wirelessly, locally, or using device-specific commands.
In some embodiments, the upper threshold for accurate measurement is greater than 90% filled. In some embodiments, the high fragment threshold for that cartridge and/or device is determined by taking the ratio of the fill fractions calculated based on the sensor readings of the first two sensors and taking their ratio. A ratio less than 1.05 indicates being within the high segment threshold, with filling% (assuming the cartridge is at 100% at the time of replacement) estimated using R/PRT. This may require date and time stamping of the device when the cartridge is replaced, and tracking of the accumulated pump run time (T/PR) since the "cartridge replacement" time stamp. The estimated fill level is calculated as 100% - (R/PRT (T/PR ÷ box volume).
In some embodiments, the lower threshold for accurate measurements is less than 12% filled. To determine whether the cartridge is within the lower threshold, two absolute value ratios are calculated using the two lowest sensors (numbered 5 and 6 in this example): 1) sensor 5 low (S5L)/sensor 6 low (S6L) |; and 2) | sensor 6 high (S6H)/sensor 6 low (S6L) |. If | (S5L/S6L) | is less than 1.5 and | (S6H/S6L) | is greater than 2.0, then the low-fragment algorithm with timestamp is triggered. The estimated fill level is calculated by taking the last reading and subtracting the% depletion based on R/PRT pump run time since the low segment timestamp.
In embodiments, knowing the distance of the magnet from the sensor/switch may be sufficient to determine the position of the float within the package, which may be used to determine the liquid level. For example, if there is a hall effect sensor/switch at the top of the package, the float always moves downward away from the sensor/switch. However, when there are multiple hall effect sensors or switches, some analysis may be required to determine in which direction the float is positioned relative to a particular hall effect sensor or switch. The output voltage from each hall effect sensor/switch can be used to accurately place the magnetic float along the direction of travel. For example, if the float happens to be located between two sensors or switches (e.g., sensors a and B), they can each output the same voltage. As the float moves, the output voltage at sensor a may increase, while the output voltage from sensor B may decrease. Thus, the computer can determine that the float is definitely moving toward sensor a and away from sensor B.
In embodiments, a model may be used to determine the position of the float inside the package based on the output voltage from each hall sensor or switch disposed along the package. For example, the output voltage of each hall effect sensor or switch may be known for each location in the package. The model may classify each location in the package by a set of output voltages. Thus, when it is desired to know the location in the package, the set of current output voltages can be compared to the model to determine a best fit between the set of current output voltages and the known sets of output voltages. In an embodiment, when fitting this set of current output voltages to those in the model, larger output voltages may be given higher weight because those output voltages may be more accurate than smaller output voltages.
In an embodiment, each hall effect sensor or switch outputs a voltage as the magnetic float moves along the track past the level sensor plate 2412 outside the package. The output voltage may be transmitted to a computer, such as an on-board computer or a remote computer. The output voltages may be fitted to an output voltage model to determine which set of output voltages in the model is the best fit. In an embodiment, higher output voltages may be weighted more heavily in the fit. Based on the best fit, the position of the float inside the package can be determined. In embodiments, when there is no good fit to a set of voltages in the model, this may be an indication of a defect, fault, error location, or intervention to the device.
In another embodiment, the level sensor plate 2412 may include a linear hall sensor if a continuous signal associated with the level measurement is desired. In this embodiment, the magnetic float 2320 may include two small magnets disposed a known distance from each other, magnetized in opposite directions. Depending on the distance and size of the magnets, the horizontal field component may be linear over a range. The distance between the linear hall sensors on the liquid level sensor plate 2412 can be selected such that at least one sensor is within the linear range of the magnetic float 2320. From the outputs of the sensors, it can be decided which sensor output is to be employed. If only discrete steps of the liquid level need to be known, an array of Hall effect switches can be used with a single magnet in the magnetic float 2320. Table 4 depicts a matrix showing the overlapping ranges of sensed positions using a small number of hall-effect switches (three in this case) to detect multiple distinct positions (six in this case).

Table 4 shows: when the switch is not switched on, the magnetic floater is between 0mm and 10 mm; when the switch 1 is switched on, it is between 10mm and 20 mm; when switches 1 and 2 are on, the float is between 20mm and 30 mm; when only switch 2 is on, the float is between 30mm and 40 mm; when both switches 2 and 3 are on, the float is between 40mm and 50 mm; and when only switch 3 is on, the float is between 50mm and 60 mm.
In one embodiment, another way of measuring the liquid level inside the package may include a float system with reed switch/magnet technology. The float, equipped with a magnet, can move up and down along the sealed tube with the corresponding liquid level. The magnetic field generated from the float can actuate a series of reed switches mounted within the sealed tube. The series of reed switches may be combined with a resistor to form a voltage divider. When a regulated DC voltage is applied to the applanation system, the resulting voltage output may be proportional to the liquid level.
In one embodiment, another way of measuring the liquid level inside the package may include a non-contact ultrasonic level sensor.
In embodiments, when an outdoor environment or a place without an enclosure needs to be saturated with scent, it may be necessary to accommodate wind when emitting scent or neutralizing. For example, the scent diffusion device may have an on-board sensor, or may otherwise communicate with or receive data from a wind sensor-based NOC. In certain embodiments, a plurality of scent diffusion devices can be deployed in an arrangement, such as a staggered arrangement, angled relative to another device (e.g., orthogonally, acutely, or obtusely), etc., in an area to be scented. The operation of the device may be coordinated remotely or locally based on data (such as wind direction or wind speed) from one or more wind sensors deployed in the area. For example, if wind moves from left to right, the devices on the left side of the area may be activated, while the devices on the right side may be deactivated, as their scent will only be carried away outside the area. In another embodiment, a single device or multiple devices may be switched between scents based on wind direction or wind speed. For example, if wind is blowing in a direction close or adjacent to a bakery, the aroma of the baked food may be diffused, but if the wind direction is changed to blow close or adjacent to a florist, the floral aroma may be diffused. In yet another embodiment, to compensate for wind speed, an onboard fan may be accelerated, or an additional fan may be activated to enhance the speed at which odors diffuse into the area. The additional fan may be integrated into the device or located external to the device.
In embodiments, a thermistor on the diffusion device can determine whether the ambient temperature of the device installed outdoors is too cold to operate. At certain temperatures, the scented oil in the device may freeze, causing the system to clog or experience some other temperature-dependent change in viscosity. For example, to automatically turn off the device when it is too cold, the switch of the device may be programmed to receive information from the thermistor, or may be physically connected to the thermistor such that when the thermistor detects cold, the device turns itself off. In an embodiment, the device may initiate an alert or message to the user or control center that the temperature is too low and the device has been turned off. In other embodiments, the device may be turned off remotely when a temperature is predicted or sensed in the area. In still other embodiments, the pump power may be altered to normalize diffusion rates and account for changes in the liquid oil viscosity as determined by temperature measurements by means of a thermistor.
In one embodiment, a remote expansion chamber may be used with the odor diffusing device. In embodiments, the output of the scent diffusion device operating as described herein may be connected to an external expansion chamber. For example, the odor diffusing device may be installed in a space that is not connected to the space to be treated. By deploying one or more remote expansion chambers, tubing from the scent diffusion device may be extended to the one or more expansion chambers, wherein the scent will eventually diffuse from the output end of the remote expansion chamber. The control of the diffusion may be performed at the odour diffusing device, or at a remote expansion chamber, or at any point along the connection between the device and the external chamber. In embodiments, not every expansion chamber may be equipped with a diffuser, or not every expansion chamber (even if equipped with a diffuser) will be programmed to diffuse.
In embodiments, the parameters of the expansion chamber may be based on a location within the odor distribution system. In embodiments, a set of expansion chambers connected to the scent diffusion device may be deployed with valves for switching on and off diffusion from the expansion chambers, such as in a linear array or other topology of expansion chambers (such as a T-shape or ring shape) or integrated into a larger system (such as an HVAC system or other environmental system). The valve or expansion chamber may include any of the sensors or other hardware described herein to implement any of the control techniques described herein, such as control over a wireless network, manual control, control by motion detection, control by detecting a particular individual in the vicinity of the expansion chamber, and the like. In embodiments, the valve may be a ball valve or some other suitable valve that can adjust the orifice size of the diffusion output. For example, the pressure in the expansion chamber may drop the further away the expansion chamber is disposed from the diffusion device. To accommodate the pressure drop, the pore size can be varied such that the diffusion rate or amount remains constant. In an embodiment, pressure sensors distributed along the expansion chamber may provide feedback to nodes on the network or the NOC to allow automatic control of the valves and balancing of the pressure throughout the system.
In embodiments, the size of the remote expansion chamber and the size of the input and output orifices may be variable as desired. In one example, the remote expansion chamber size may be based on how far it is located in the linear array.
In an embodiment, the remote expansion chamber may be managed based on modeled time for filling and diffusion.
In embodiments, the linear array of remote expansion chambers may be configured to fit a building facility, such as to include elements of concealed hoses. In embodiments, a linear array of remote expansion chambers may be arranged for a particular installation type, such as a long hallway and a large conference hall. In embodiments, the linear array of remote expansion chambers may take into account characteristics of the environment at the time of deployment, such as a safe area of a facility that does not need to be scent-filled, but is located between two spaces that need to be scent-filled, may utilize a linear array that skips the safe area through a long connection.
In an embodiment, the tool may be used to configure a linear array of remote expansion chambers based on spatial specifications of the space. The separator may be used to generate a plurality of distribution lines for an array of expansion chambers attached to a common pump system. In embodiments, the expansion chamber may be deployed in an odor distribution system using a combination of separators and one or more linear arrays for producing a plurality of distribution lines.
In one embodiment, the diffuser device may use TCellTM technology to diffuse scented oil. The TCellTM technology may include a fuel cell that generates hydrogen in a formulation chamber. As each molecule of hydrogen is produced,it will force an equal amount of scented oil out of the chamber. In embodiments, natural air flow or fans may distribute the fragrance throughout the room. In embodiments, diffusion is performed by rewetting the immobilization medium. In embodiments, an odor oil chamber may be disposed above the wicking material, and a vacuum may be present in a headspace of the chamber containing the oil. When TCellTMWhen the technique is activated and the gas is released, the vacuum is broken and oil is forced from the chamber into the wicking material. The timing circuit may be used to control when to activate the TCellTMProvided is a technique. In an embodiment, the chamber may comprise a mesh dome of wicking material with oil on the inside.
In embodiments, an array of remote expansion chambers connected to a diffusion device may each have a TCellTMProvided is a technique. Indeed, the odor diffusion device and remote expansion chamber may utilize a T-CellTMEither technique or gas-effected atomization to diffuse the scent. For example, a single diffusion device may have a large reservoir of scented oil that is diffused into the remote chamber through tubing connected to the diffusion device. The remote chamber may have a TCell TMTechniques such that each remote chamber receives scented oil from a macro reservoir, wherein dispensing of scented oil from the macro reservoir may be controlled such as described herein, and when TCellTMTechnical mechanisms are activated to further dispense through the TCell from the remote chamberTMA technical mechanism to do so and also to control as described herein. For example, with TCell for diffusionTMA linear array of remote chambers of the technology may receive scented oil from a large reservoir connected to a diffusion device, and the remote chambers on the linear array may be activated all at once or in some other pattern to diffuse scented oil along the linear array.
In embodiments, the diffusion device itself may be adapted to accommodate utilization of the TCellTMTechnology replaces the gas-mediated diffusion packages described herein, where diffusion devices may be networked, such as in a mesh network or other network topology, in order to be controlled to diffuse the contents of the package.
In an embodiment, TCellTMThe diffusion device may be embodied in a motor vehicleIn the ventilation clamp. In one embodiment, TCellTMThe diffusion device may be configured as a circular vent clip with self-wicking features in a geodesic dome configuration for self-wicking independent of a particular placement direction.
