Technical Field
The present invention relates to a customized beverage making device, system and method, including such a device for flavoring, filtering and carbonating a beverage.
Background
Traditionally, people have purchased beverages from local stores, or more recently, via online delivery services. Such beverages may include flavored beverages, carbonated beverages, and even basic beverages such as filtered water. These beverages are sometimes purchased in bulk in containers. These containers may be bottles, each of which may hold, for example, 1 liter of water, or larger containers. When the contents of one container are consumed, the other container is retrieved and opened for consumption. This process is very convenient, requiring only occasional visits to the store (or online clicks in the case of online ordering of beverages), occasional handling and replacement of empty containers. Although this beverage access method is simple, it generates a large amount of waste (usually plastic waste, since the containers are usually made of plastic). Therefore, the development of a home beverage making system is expected to reduce waste.
In developing a home beverage making system, the convenience of beverage making is ideally close to or better than the convenience of the existing beverage acquisition methods already described above. In particular, in order to further reduce the workload involved in existing beverage acquisition methods, at least some of the following problems may be further eliminated: 1) a need to go to a shop to replenish the beverage containers, 2) a need to handle empty containers, and a need to store crates with full containers. These problems should be solved while 3) avoiding the introduction of new significant inconveniences. Furthermore, the beverage making system may introduce new advantages, such as the continuous making of customized beverages at a lower cost than traditional beverage procurement.
Each of these problems can be solved by creating a home beverage making device that allows a user to make a beverage from tap water or water from another source (e.g., a dedicated pipe or tank) that can be filtered, flavored, and carbonated according to the user's specifications. There are several existing devices that attempt to do this, but doing so can cause new inconveniences to the user. We propose a novel customized beverage making device herein that has unique functionality to avoid the inconvenience of other prior devices.
Generally, in various embodiments, the apparatus is designed to enable or facilitate one or more of the preparation, personalization, or purification of water and flavored beverages.
Current processes for the preparation of water and beverages are time consuming and cumbersome, requiring the bottles to be cleaned, the water to be cooled, and the water to be filtered, carbonated and flavored by different processes. Users often end up with disposable plastic bottles in order to avoid the cumbersome process of preparing beverages.
For personalization of water and beverages, family members or commercial establishment customers may prefer different types of water and flavored beverages of slightly different formulations. For example, a user may prefer beverages with different carbonation levels, different temperatures, or different flavors. Even if the recipe is repeatable, it is difficult to accurately dispense ingredients such as flavoring syrups. Therefore, it is difficult, if not impossible, to repeatedly prepare a beverage without proper equipment.
Purifying water using existing systems is often expensive, wasteful, cumbersome, and/or requires large equipment. Such purification may further remove beneficial minerals. Consumer oriented filters (e.g. pitchers) are unreliable and inconsistent and have low capacity. The water tank you use may be used up just as you need it.
In addition, users of such systems may prefer carbonated beverages. There are several methods to mix water and carbon dioxide (CO2) to make carbonated water. In one method, pressurized carbon dioxide (e.g., about 1000PSI) is released directly from a pressurized canister into a thin tube that delivers the carbon dioxide to a thin "injection straw" (about 3 mm ID). Carbon dioxide can escape from the bottom of the syringe through a small opening (about 200 microns) into a container filled with about 85% by volume water (i.e., 15% of the container's internal volume is "headspace"). The tip of the syringe through which carbon dioxide escapes is located just below the water level in the container. In this way, carbon dioxide is injected at a very high rate directly from the tip of the straw into the water to be carbonated. Such high-speed injection causes vigorous agitation of the water, thereby promoting mixing and dissolution of the injected carbon dioxide with the water, thereby generating carbonated water. Although the carbon dioxide is sprayed directly from the pressurized carbon dioxide tank into the water at high speed without any pressure regulation, the outlet orifice of the injection straw is small and the flow rate is slow, so that the container takes a certain amount of time to reach high pressure (about 3 seconds to 150 PSI). This extended mixing time allows the agitation and mixing of the liquid to continue for a sufficient time for adequate carbonation to occur. The restriction of the carbon dioxide flow rate by the injection straw also helps to increase the time required for the carbonation container to reach dangerous PSI levels, thereby allowing the use of a lower PSI grade carbonation container than the pressurized carbon dioxide tank storing carbon dioxide, despite the absence of a pressure regulator in the flow path therebetween.
The rate of carbon dioxide injection into the water in the carbonation vessel is high and is a method of physically propelling and mixing the water. However, the physical orientation of the injection straw with respect to the water is also important. By pointing down into the water, rather than from below or from the side up, such systems take advantage of the natural tendency of carbon dioxide gas to want to rise through the water (because carbon dioxide gas is lighter than water). Because of this natural tendency of carbon dioxide gas, injecting carbon dioxide down into water will result in approximately twice the contact time between the carbon dioxide bubbles and the water (i.e., on both the downward injection path and the upward buoyant path of the gas), and twice as much mixing as possible (i.e., the bubbles push the water along its downward and upward paths).
After the initial carbon dioxide injection, the pressure within the carbonation chamber increases (i.e., above the initial atmospheric pressure). This pressure also aids the carbonation process because it actually forces the carbon dioxide molecules into closer contact with water molecules. If the pressure in the carbonation vessel is reduced back to atmospheric pressure by opening a "pressure relief valve", some of the carbon dioxide dissolved in the water will immediately begin the process of separating from the water, thereby reducing the carbonation of the mixture. If such a pressure relief valve is left open indefinitely, then over time all of the carbon dioxide will escape from the water and the water will not carbonate anymore. A daily specification of this concept is that carbonated water will fade if it is left in an open bottle for a sufficiently long time. If all of the carbon dioxide is separated from the water and allowed to float to the atmosphere, either by repressurizing, re-stirring or cold storage of the carbonation vessel (or carbonated water bottle), the water cannot be re-carbonated because the carbon dioxide will no longer be re-mixed with the water.
This concept can be problematic for any long-term (hours or days) bottle of carbonated beverage, involving multiple openings and closings of the container (e.g., a typical carbonated water bottle). Each time the container lid is opened for drinking, carbon dioxide escaping from the water, and thus remaining in the "headspace" above the liquid level, can escape to the atmosphere through the upper opening of the container. This means that the carbon dioxide that accumulates in the headspace of the bottle is lost each time the bottle is opened and, as previously mentioned, any subsequent re-pressurisation, re-stirring or refrigeration of the bottle does not assist in returning any carbonation. Furthermore, even if the container is still capped, the closure is not perfectly sealed and, even if it is kept capped, the closure will continue to leak carbon dioxide slowly, ensuring that carbonated water placed in the bottle and manually sealed will inevitably lose carbonation over time. An imperfect solution used by some carbonated beverage users is to place the bottle in the refrigerator, inverting it, moving the non-gas-tight cap from the highest point of the bottle (where carbon dioxide gas will collect in the mouth space) to the lowest point, where only water will contact the cap (because the carbon dioxide floats upwards). This limits the loss of carbon dioxide to an amount that can only diffuse to the entire vessel wall.
There is a need for a beverage making device, system and method that can reproducibly flavor a beverage and increase the absorption of carbon dioxide in the liquid and/or allow the fluid to retain carbon dioxide at a higher rate than existing devices.

Each filter segment may be, for example, a large particle filter, a particulate or solid bulk carbon filter, a microfiltration membrane, a nanofiltration membrane, and the like. It will be noted that although the present disclosure discusses a carbonation method, the user may still dispense still water immediately after the filtration process. Thus, a still water dispensing solenoid (solenoid) can be used as a valve to release filtered still water directly to the output of the device.
The
Finally, another option for allowing the machine to obtain a water supply is to have the
In such an embodiment, a standard under sink mounted diverter may be provided on the cold or hot water line (relative to the water temperature required by the device), the diverter being connected to a filter which is connected to a long coiled hose which terminates in a manually or electronically controlled valve. With such a system, whenever it is desired to refill the tank of the counter top device, the user can disconnect the hose from under the sink, extend its end into the tank of the machine, and then activate the valve at the end of the hose to allow water to flow into the tank to refill it.
In addition, many kitchen appliances require the use of water in a particular temperature range. For example, a refrigerator may only require cold water to perform the necessary functions. However, it is not always convenient or possible for a user to install a conventional under sink shunt hose from a hot or cold water pipe or to drill a hole in a countertop to install the hose. Thus, a valve device may be provided which is connected to a hot or cold water tap knob, allowing for diversion at that point rather than under the counter.
Thus, water can be drawn from an under-sink tee that is spliced to a user water supply line, an accessory water tank, or a faucet connected to a tee. Any of these mechanisms may further employ a water pressure regulator.
The refill station may be powered by a standard outlet power adapter or by an on-board rechargeable battery (e.g., lead-acid battery). The battery may be charged by connecting to a charging circuit connected to an electrical outlet and/or by drawing power from water turbine 1400 and/or a carbon dioxide gas turbine. Hydro turbine 1400 may be mounted at any location along the water flow path through the machine components. The optimal positioning would be at the point of first contact with the user's home water supply (e.g., the sink head, or any other point of integration with the user's water supply) so that it will generate electricity (i.e., water will flow through it) both when the user commands water to be poured into their sink (blue arrow) and when the machine commands water to flow through their pipes (red arrow). An electrical cord may connect the turbine to the machine's battery along the path of the machine's water line. Also, the carbon dioxide gas turbine may be located somewhere in the gas path from the compressed carbon dioxide tank of the machine to the carbonation tank of the machine so that when carbon dioxide gas is injected into the carbonation tank to carbonate the water, it generates electricity. In some embodiments, instead of using a turbine, solar energy may be used to power the refill station and other components of the device.
The
The amount of carbon dioxide remaining in the compressed carbon dioxide storage tank to which the apparatus is connected can be estimated by the amount of time required for the carbonation tank to reach a certain pressure (e.g., 150PSI) after activating the pin valve of the compressed carbon dioxide tank. This amount of time is a function of the flow rate of carbon dioxide from the tank into the carbonation tank and also a function of the pressure remaining in the compressed carbon dioxide tank. In some embodiments, the amount of additive remaining in the

Furthermore, when a user requests carbonated water, a separate valve may first release carbon dioxide to reduce the pressure within the carbonation vessel, thereby avoiding excessive flow to the user. In addition, an air pump may be provided to discharge carbonated water after the carbon dioxide is released, so as to dispense the carbonated water at a consistent rate. A large diameter valve may be provided to dispense water to avoid over-stirring which would otherwise release carbonation of the water.
Several methods are available to assist in carbonation, including increasing the contact time between carbon dioxide or other carbonated gas and water or any other fluid to be carbonated, increasing the contact surface area between the carbonated fluid and the fluid to be carbonated, increasing the pressure, and decreasing the temperature. For ease of reference, the carbonated fluid is sometimes referred to as carbon dioxide and the fluid to be carbonated is sometimes referred to as water.
The contact time between water and carbon dioxide can be increased by several methods. For example, as shown in fig. 15A and 15B, by adding a spiral step-type structure within the carbonation vessel. This "step" may be "stepped" like a step, may be smooth like a ramp, or may repeat various other structural subassemblies along its length, as will be described later. The steps will extend from the walls of the
Thus, fig. 15A and 15B illustrate one example of a

Such wings 1600 may be configured to direct any downward flowing water stream, such as a water stream captured by injected carbon dioxide or pushed downward, creating a downward spiral motion. This downward spiral motion will be opposite to the rotational direction of the upward spiral motion on the underside of the step, creating additional agitation.

Increasing the surface area of the carbon dioxide and water can be accomplished by various methods. Breaking up the bubbles into smaller bubbles is a method because smaller spheres have a higher surface area to volume ratio than larger spheres.
Fig. 18 shows an alternative embodiment of a
Another way to increase the agitation in the water, thereby using the water as a force to agitate the gas and break up the bubbles, is to induce the formation of a vortex. Vortices, like small vortices, can be created by forcing a liquid or gas past a specially shaped obstacle. These obstacles may be placed along the inner wall of the carbonation container.

In some embodiments,
One problem with the prior art systems discussed previously is that if a user places a carbonated bottle into a refrigerator, the manual tightening of the cap of the bottle cap will maintain an imperfect seal, thereby allowing carbon dioxide to slowly leak from the bottle. Furthermore, whenever the cap is opened to drink and then re-capped, the carbon dioxide that has left the water and is in the headspace will escape to the atmosphere, further reducing the pressure in the bottle, reducing the amount of carbon dioxide in the bottle, further accelerating the decarbonation process of any water remaining in the bottle, even if the bottle is refrigerated, re-agitated or re-pressurized.
To solve this problem, several solutions are disclosed. These solutions revolve around the general idea of capturing any carbon dioxide that separates from the water during natural decarbonation and trapping this separated carbon dioxide in a gas pocket that is not exposed to leaks and to an occasional open bottle cap (which opens when the user gets a beverage). These carbon dioxide capture schemes will cause the carbonated water dispensed into the capless bottle to "retain" more carbon dioxide than a capless bottle without these carbon dioxide capture mechanisms, as the latter carbon dioxide can simply be bubbled out of solution and through the mouth of the bottle into the atmosphere. If the water is first chilled, any carbon dioxide captured by the mechanism described below can then be re-mixed into the water to re-carbonate it to some extent (as colder water can be more easily carbonated by stirring than warmer water).
Similar to

To avoid the potential for liquid carbon dioxide to escape from the tank, most systems using compressed carbon dioxide require the carbon dioxide tank to be placed vertically so that liquid carbon dioxide cannot enter the outlet valve of the tank. In situations where a horizontal orientation of the tank is required, an anti-siphon is typically used. These are curved "diplegs" extending downwardly from the outlet valve of the carbon dioxide tank and into the carbon dioxide tank, the diplegs having an upward bend to ensure that only gaseous carbon dioxide enters the anti-siphon tube and exits the outlet valve. The anti-siphon tube, when working properly, needs to be carefully installed to ensure the correct orientation of the carbon dioxide canister so that the curve of the internal anti-siphon tube points in the correct direction (upwards with respect to the ground).
As shown,
Fig. 26A shows a block diagram of a
As shown,
Alternatively or in combination, the gas used to inject the fluid may be an off-gas, such as the gas in the head 2630 of the
With respect to the carbonation process itself, one method of carbonating water is commonly referred to as "forced carbonation". In "forced carbonation", carbon dioxide bubbles were initially bubbled into the water through an "aerator stone" in a pressure vessel at a pressure of 80 PSI. As the bubbles rise through the water column, part of the carbon dioxide dissolves into the water and the remainder accumulates in the headspace (the gaseous region above the water level in the pressure vessel). The pressure of the pressure vessel is maintained at a pressurized pressure, in this case 80PSI, to allow the carbon dioxide in the headspace to passively and slowly diffuse into the water below.
Traditional "forced carbonation" requires time. One factor limiting the speed of this passive dissolution process is the surface area of the carbon dioxide-water interface. To increase this surface area and thus increase the rate of passive carbonation, we propose to increase the surface area of the carbon dioxide-water interface. One way to achieve this goal is to trap the rising carbon dioxide bubbles under water when they are initially injected into the water (by aeration rocks or other means) before they reach the headspace. To this end, a large number of small overhangs may be placed along the inner wall of the carbonation vessel, as shown in fig. 17-20A, or possibly in the middle of the carbonation chamber (e.g., attached to a tree-shaped object inserted into the pressure vessel), as shown in fig. 20B-20C. These overhangs trap tiny carbon dioxide bubbles as they rise (due to their buoyancy) after the initial injection of carbon dioxide.
In addition, there are several methods for preparing carbonated water, all using a combination of temperature, pressure, time, and mixing or stirring. Two of these methods include "forced carbonation" as described above, which is slower, and the agitation-based method is faster. Although the stirring process is rapid, it is not efficient in utilizing carbon dioxide when producing highly carbonated water. This is because, in order to increase the amount of agitation and mixing (achieved by injecting carbon dioxide at high speed), it must occasionally release carbon dioxide into the atmosphere to reduce the pressure within the pressure vessel, thereby allowing more carbon dioxide to be injected to further agitate the carbon dioxide/water mixture.
Figure 26B shows a hybrid carbonation process that may combine a forced carbonation process with a stirred process. This mixing method takes advantage of the ability of the agitation method to effectively reach moderate carbonation levels and then passively continues the carbonation process over time using the ability of the forced carbonation method. The following is an example scenario of this hybrid system used in the
Initially, a carbonation container (2655) is provided and substantially filled with a fluid to be carbonated (2660), such as water. When the container is substantially full, it may be filled to the fill line such that a known amount of headspace remains in the container, and thus carbonation may provide consistent results. The
Since carbon dioxide is not released, forced carbonation may be performed, including maximizing the use of the internal structure shown in fig. 17-20C. Accordingly, carbonation proceeds over time to achieve "maximum carbonation" of the water.
If the user desires to carbonate the beverage (2673), the
After the water is carbonated to a desired level, the
In some embodiments, the user may specify a desired carbonation level in a particular beverage. In this case, if during the wait time, the user requests medium or mild carbonated water, the
One novel aspect of the
Off-the-shelf LLS already exists in a variety of forms including "floating switches", optical systems and conductivity based systems. Although these sensors could theoretically be used in "endless tank" systems, we propose several novel liquid level detection methods here that have advantages over existing off-the-shelf sensors.
The latter ('B') can be achieved by any kind of identifier connected to the container. This may be RFID, bar code, unique color or shape, etc. Further, the use of identifiers to track the most recent beverage for filling any beverage container, whether or not it is used as part of an endless container system, may be implemented. Thus, a user may have a glass or bottle with an incorporated RFID tag that identifies a previous container. When a user refills the container at the
One embodiment of such an "endless container" system may include coupling an RFID chip to a container. By coupling with the container, the RFID may in some cases serve both as an LLS (as described further below) and as an identification tag that the beverage dispensing machine may use to know exactly what beverage it should refill the container (e.g., the same beverage it previously filled the container with). The RFID chip will be able to transmit its unique ID to the beverage dispensing device in the following cases: 1) whenever an RFID is within sufficiently close range of its RFID reader, and 2) whenever an RFID is not intentionally or unintentionally blocked from its signal by signal blocking substances such as metals and water.
Fig. 27A and 27B illustrate one embodiment of a
As shown, the
The transmission range of RFID data is limited by a number of factors, including the size and orientation of the antenna, the amount of voltage and current used, etc. In addition, certain materials, such as metal or water, if located between the RFID and its power source or receiving antenna, may block or attenuate data transmission from and/or transmission power to the RFID. By utilizing these concepts, it is possible to install an RFID inside a float 2700 (e.g., a plastic ball) inside the

Accordingly, the
Fig. 29A and 29B illustrate an alternative embodiment of a liquid level detector 2900 used in a beverage container 2910 in two states. In the illustrated embodiment, the liquid level detector 2900 is embedded in the base 2920 of the beverage container 2910. In such embodiments, the antenna 2930 for acquiring signals from the liquid level detector 2900 is mounted adjacent to the outer wall 2940 of the container 2910. Thus, when the container 2910 is full, the liquid level detector 2900 will be completely covered, and the beverage 2950 will block the space between the detector and the antenna 2930. Thus, when the beverage is depleted, a signal from detector 2900 may be retrieved via antenna 2930.

In such embodiments, the walls of the container may be made of a combination of
Thus, the

As shown, in addition to
Additional embodiments of the "endless container" concept are also contemplated. For example, rather than relying on electronic detection of the need to refill a beverage, an "endless container" may also be implemented by relying on the user to place it into a container filling station only when the user wishes to fill it. Thus, the system would not require a LLS, but only the container would need to have an identification mechanism so that the refill machine could know the type of beverage previously added to the container and refill the container with the corresponding beverage. The identification mechanism may be coupled to the container in a variety of ways, including by embedding the identification mechanism into the container during manufacture, or by being adhered to the container by a user through the use of an adhesive or tape, or the like. The identification mechanism itself may be an RFID, a bar code, a unique color or shape, or any number of other existing mechanisms.
Furthermore, although RFID does not require an on-board power source, LLS systems with active data transmitters may be used as an alternative to RFID. Such transmitters require an on-board power source to operate. This power may be provided by a battery or capacitor connected to the LLS and this connected battery/capacitor may be charged whenever the container is placed into a refill system with its own power source (which may be a battery, wall outlet, solar, hydro, etc., as described elsewhere in this application). The wireless charging can be carried out by contacting the electrodes, winding coils and even by laser transmission (a solar panel is arranged on the container) and the like. Any container usage data recorded by the sensors on the container during this charging process may also be transmitted to the refill system.
Some embodiments may implement methods and systems for refilling a container with the correct amount of beverage. The refill system may refill the same bottle from which the depleted beverage has been detected, or alternatively, the refill system may fill a separate empty bottle with the same beverage from which the user has been detected to have been depleted from the bottle. In the former case, the refill station may refill the container upon detecting that the depleted container is placed below the beverage bottle mouth. In the latter case, the refill station may refill a new container whenever a) the in-use container is within data transmission range of the refill station (i.e., when it can tell the refill station that it has been depleted) and B) the in-use container has been depleted beyond some set threshold.
In embodiments where the system fills the second bottle when the first bottle is depleted, alternative methods for notifying the device of depletion of the first bottle are contemplated. For example, a user may manually send information to the system using, for example, an application associated with the system. Alternatively, a drive base may be provided for the first bottle remote from the second bottle at a convenient location. For example, a sensor and drive base designed to work with any of the embodiments of fig. 27-31 may be provided to be placed on a table or in a user's refrigerator. Thus, when the depleted bottle is returned to its base on a table, or to a refrigerator, a second bottle will automatically fill up for retrieval by the user.
In the case of a completely new container being filled or a completely empty container being refilled, the refill station may refill the container with the same amount of liquid previously recorded, whereas in the case of a partially depleted container being refilled, the refill station will only add enough beverage to fill the container without spilling it. This "topping up" can be achieved by combining the following two approaches: A) using a weight scale, B) knowing the weight and maximum beverage carrying capacity of the filled receptacle, C) subtracting the known weight of the receptacle from the weighed weight to calculate the weight (and thus the volume) of the liquid currently remaining in the receptacle, and finally D) adding enough beverage to fill the receptacle.

If the refill pack's cover is fitted with an array of permanent magnets, a similar concept can be used to transfer information directly from the large syrup refill pack to the bay, whereby the magnets will abut the magnetic stripe on the cartridge (e.g., if the magnetic stripe is on the cartridge's cover, it will press against the refill pack's cover when the bay is being filled).

One purpose of the dome-shaped syrup tube is to prevent the syrup from dripping from the chamber when handled by the user. A larger internal cross-section of the pipe allows for faster and easier pumping of fluid into the pipe (less friction). However, when fluid enters the horizontal portion (e.g., U-shaped portion 3750) of the conduit from the vertical portion of the conduit (e.g., the vertical outlet side of the syrup conduit), if the horizontal portion has a "high" internal dimension, then the water will spread out from the "ceiling" of the conduit under the force of gravity and be drawn away, allowing any air to easily bypass any air that previously pushed the droplets in the vertical portion of the conduit. This air bypass margin can prevent successful droplet pickup through the horizontal portion of the conduit. Thus, in order to prevent such suction failure and to allow the droplets to be successfully sucked back into the vertical inlet side of the syrup tube, the horizontal portion of the syrup tube must have a "short and wide" dimension, allowing the gravity flattened droplets to still fill the entire cross-section of the tube, and still allowing the suction to draw all of the syrup from the outlet side of the syrup tube to the inlet side of the syrup tube.

Cleaning pipes is often problematic because the pipes are long, small diameter channels that are difficult to clean using conventional cleaning mechanisms, such as high velocity water or scrubbing perpendicular to the pipe wall. It is unlikely that a user such as the described
For example, one way in which the cleaning process can be simplified is to replace the siphon or

Forming a good pneumatic seal is more difficult than forming a good hydraulic seal because gas is more likely to traverse smaller seal defects (e.g., gaps or cracks in the seal) than fluid. Typical pneumatic sealing solutions include the use of O-rings or adhesives or fillers, such as thread-lock glue, silicone sealant or teflon tape, which can minimize the gaps through which the gas passes. Such a solution may not be effective enough for the
These unique requirements stem from the fact that the
Thus, as shown in fig. 48, the seal may be provided as a magnetic coupling. In such an embodiment, the magnet 4830 would be located on the cartridge docking station 4810 or the
By sandwiching the rubber-like material, a strong seal can be formed. Because the seal is magnetic, the coupling does not require a male/female or male/female fit, and an unskilled user can apply and disengage the coupling.

Moreover, because of the gripping action of lid 4910, the lid surface that mates with docking station 4930 and base 4900 may be relatively simple, with minimal gaps in which additives may accumulate and become hard and difficult to clean. For example, the mating surface may simply be a flat surface that increases the contact surface area between the components.

To ensure that the spout 5610 is in the desired designated position, the docking position may include a detection mechanism so that proper cartridge orientation can be confirmed. As shown in fig. 57, this may include magnets in the lid 5710 and base 5720, respectively, that must be properly aligned for the cassette to mate with the base. If the magnets are misaligned, the

Another type of sensor that can detect liquid droplets is a reflective object sensor 5900, which takes advantage of the fact that water is an Infrared (IR) reflector. Such reflective object sensors include an infrared emitter and an infrared detector that are oriented such that they are at an angle to each other to allow the emitter IR beam to reflect back to the detector if a reflective object is placed at some distance in front of them. The sensor 5900 will be mounted within the
