Detailed Description

The foregoing summary, as well as the following detailed description of certain embodiments, will be better understood when read in conjunction with the appended drawings. As used herein, an element or step recited in the singular and proceeded with the word "a" or "an" should be understood as not necessarily excluding plural elements or steps. Furthermore, references to "one embodiment" are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features. Furthermore, unless explicitly stated to the contrary, embodiments "comprising" or "having" an element or a plurality of elements having a particular condition may include additional elements not having that condition.

Certain embodiments of the present disclosure provide a portable disinfection system that disinfects a surface (e.g., within an interior compartment of a vehicle). The portable sterilization system includes a wand assembly and a backpack assembly. The wand assembly includes a housing, a UV lamp, a reflector, a mount securing the UV lamp to the housing, an inlet allowing air to be drawn from the UV lamp, and an extension handle configured to extend the reach of the wand assembly. The backpack assembly includes a body or housing, a power supply, one or more batteries (e.g., rechargeable batteries), a plug to charge the backpack, a blower, a carbon filter, vents, and straps to allow an individual to wear the portable sterilization system.

The effectiveness of a UV disinfection system depends on the dose (e.g., mJ/cm) required to kill the target pathogen²). The dose is a function of the optical power (in watts) and exposure time of the UV light. Embodiments of the present disclosure provide a training and pacing audio system that provides prompts (e.g., audio prompts) to a user, allowing them to provide the correct amount of time for disinfecting UV light exposure. Embodiments of the present disclosure allow a user to adjust the motion of the wand assembly during sterilization to ensure that the correct dose of UV light for sterilization has been delivered. Embodiments of the present disclosure guide the user according to the desired irradiance dose and/or the particular item or items being sterilized.

Certain embodiments of the present disclosure provide a method of pacing UV sterilization of a predetermined surface. The method includes calculating a wand velocity and loading the velocity into a computer program. The program provides audio cues relating to the rate of wand movement and may provide feedback so that the user can maintain the rate.

The audio prompt may be a series of audio files to provide voice instructions and pacing for the area to be cleaned, or may include a tone such as a metronome beat and/or cymbal sound to indicate the end of a sweep's (sweet) cycle. The audio file may be loaded into a computer program (e.g., a mobile application program) to act as an audio coach (audio coach) to instruct the user how long to keep the UV wand on the area for sterilization. The computer program may include a mobile application or other computer program that manages audio files.

The wand speed is calculated by inputting known parameters, such as distance to the surface, irradiance of the wand, sterilization energy required to sterilize the surface, wand length and wand width, to calculate the time required to sterilize the surface.

Fig. 1 illustrates a perspective view of a portable disinfecting system 100 worn by an individual 101 according to an embodiment of the present disclosure. The portable sterilization system 100 includes a wand assembly 102 coupled to a backpack assembly 104, the backpack assembly 104 being removably secured to an individual by straps 105. The wand assembly 102 includes a disinfectant head 106 coupled to a handle 108. In at least one embodiment, the disinfection head 106 is movably coupled to the handle 108 by a coupler 110.

As shown in FIG. 1, the wand assembly 102 is in the stowed position. In the stowed position, the wand assembly 102 is removably secured to a portion of the backpack assembly 104, such as by one or more tracks (tracks), clips (clips), latches (latches), straps (belts), ties (tie), and/or the like.

Fig. 2 illustrates a perspective side top view of the wand assembly 102, in accordance with an embodiment of the present disclosure. Disinfectant head 106 is coupled to handle 108 by coupling 110. The disinfection head 106 includes a shield 112, the shield 112 having a housing 114 extending from a proximal end 116 to a distal end 118. The shroud 112 contains a UV lamp, as described herein.

A port 120 extends from proximal end 116. The port 120 is coupled to a hose 122, which hose 122 is in turn connected to the backpack assembly 104 (shown in FIG. 1). The hose 122 contains electrical wires, cables, lines, or the like that couple a power source or power supply (e.g., one or more batteries) within the backpack assembly 104 (shown in fig. 1) to the UV lamp 140 within the shroud 112. Alternatively, the wires, cables, lines or the like may be external to the hose 122. The hose 122 also contains an air delivery line (e.g., an air tube) that fluidly couples the interior chamber of the hood 112 to a blower, vacuum generator, air filter, and/or the like within the backpack assembly 104.

The coupler 110 is secured to the housing 114 of the shroud 112, such as near the proximal end 116. The coupler 110 may include a securing beam 124, such as by one or more fasteners, adhesives, or the like to secure the securing beam 124 to the nacelle 114. An extension beam 126 extends outwardly from the fixed beam 124, thereby spacing the handle 108 from the shroud 112. A bearing assembly 128 extends from the extension beam 126 opposite the fixed beam 124. Bearing assembly 128 includes one or more bearings, rails, and/or the like that allow handle 108 to translate linearly in the direction of arrow a relative to coupler 110, and/or pivot about a pivot axis in the direction of arc B. Optionally, in addition to or in lieu of handle 108 being coupled to bearing assembly 128 (e.g., handle 108 may be fixed to coupler 110), stationary beam 124 may include a bearing assembly that allows disinfection head 106 to translate in the direction of arrow a and/or rotate (e.g., swivel) in the direction of arc B.

In at least one embodiment, the handle 108 includes a rod, post, beam, or the like 130, and the rod, post, beam, or the like 130 may be longer than the shroud 112. Alternatively, the stem 130 may be shorter than the shroud 112. One or more grips 132 are secured to the rod 130. The grip portion 132 is configured to be gripped and held by an individual. The grip 132 may include ergonomic tactile features 134.

Alternatively, the size and shape of the wand assembly 102 may be different than that shown. For example, in at least one embodiment, the handle 108 may be fixed relative to the shield 112. Further, the handle 108 may or may not be configured to move relative to itself and/or the shield 112. For example, the handle 108 and the shield 112 may be integrally molded and formed as a single unit.

In at least one embodiment, the wand assembly 102 is not coupled to a backpack assembly. For example, the wand assembly 102 is a stand-alone unit having a power source (e.g., one or more batteries). As another example, the wand assembly 102 is coupled to a housing assembly.

Fig. 3 illustrates a perspective rear view of the wand assembly 102 of fig. 2. Fig. 4 illustrates a perspective side view of the wand assembly 102 of fig. 2. Referring to fig. 3 and 4, the handle 108 may be pivotally coupled to the coupler 110 by a bearing 136, the bearing 136 having a pivot 138 pivotally coupling the handle 108 to the coupler 110. Handle 108 may also be configured to translate linearly in and out of bearing 136. For example, the handle 108 may be configured to telescope in and out. Optionally or alternatively, in at least one embodiment, the handle 108 may include a telescoping body that allows the handle 108 to extend outward and retract inward.

Fig. 5 illustrates a perspective view of the portable sterilization system 100 in a compact deployed position, according to an embodiment of the present disclosure. The wand assembly 102 is moved out of the backpack assembly 104 (shown in figure 1) to the compact, deployed position, as shown in figure 5. A hose 122 connects the wand assembly 102 to the backpack assembly 104. In the compact deployed position, disinfection head 106 is fully retracted relative to handle 108.

Fig. 6 illustrates a perspective view of portable disinfecting system 100 with disinfecting head 106 in an extended position according to an embodiment of the present disclosure. To extend disinfection head 106 relative to handle 108, disinfection head 106 is slid outward relative to handle 108 in the direction of arrow a' (or handle 108 is slid rearward relative to disinfection head 106). As noted, disinfection head 106 is capable of linear translation in the direction of arrow a' relative to handle 108 via coupling 110. As shown in fig. 6, the outward extension of the disinfection head 106 allows the portable disinfection system 100 to easily reach remote areas. Alternatively, the disinfection head 106 may not translate linearly relative to the handle 108.

Fig. 7 illustrates a perspective view of portable disinfecting system 100 with disinfecting head 106 in an extended position and handle 108 in an extended position according to an embodiment of the present disclosure. To reach further distally, the handle 108 may be configured to translate linearly (e.g., via telescoping sections) to allow the disinfection head 106 to reach further distally outward. Alternatively, the handle 108 may not be configured to extend and retract.

In at least one embodiment, the handle 108 may include a lock 109. The lock 109 is configured to be selectively operated to secure the handle 108 in a desired extended (or retracted) position.

Fig. 8 illustrates a perspective view of portable disinfecting system 100 with disinfecting head 106 rotated relative to handle 108 according to an embodiment of the present disclosure. As noted, the disinfection head 106 is configured to rotate relative to the handle 108 via the coupling 110. Rotating the disinfection head 106 relative to the handle 108 allows the disinfection head 106 to be moved to a desired position and swept or otherwise brought into areas that would be difficult to reach if the disinfection head 106 were securely affixed to the handle 108. Alternatively, the disinfection head 106 may not be able to rotate relative to the handle 108.

Fig. 9 illustrates a perspective end view of the UV lamp 140 and reflector 142 of the disinfection head 106 according to an embodiment of the present disclosure. The UV lamp 140 and the reflector 142 are secured within the shroud 112 (shown, for example, in fig. 2) of the disinfection head 106. In at least one embodiment, the reflector 142 is secured to the underside 141 of the shroud 112, such as by one or more adhesives. As another example, the reflector 142 is an integral part of the shroud 112. For example, the reflector 142 may be or otherwise provide the underside 141 of the shroud 112. The reflector 142 provides a reflective surface 143 (e.g., formed of Teflon (Teflon), a specular surface, and/or the like), the reflective surface 143 configured to reflect UV light emitted by the UV lamp 140 outward. In at least one example, the shroud 112 may be or include a shell formed from fiberglass, and the reflector 142 may be formed from teflon that provides 98% reflectivity.

The reflector 142 may extend along the entire length of the underside 141 of the shroud 112. Alternatively, the reflector 142 may extend along less than the entire length of the underside 141 of the shroud 112.

The UV lamp 140 may extend along the entire length (or substantially along the entire length such as between the ends 116 and 118). For example, the UV lamp 140 is secured to the reflector 142 and/or the shroud 112 by one or more brackets. The UV lamp 140 includes one or more UV light emitters, such as one or more light bulbs, light emitting elements (e.g., light emitting diodes), and/or the like. In at least one embodiment, the UV lamp 140 is configured to emit UV light in the far UV spectrum (such as at wavelengths between 200nm and 230 nm). In at least one embodiment, the UV lamp 140 is configured to emit UV light having a wavelength of 222 nm. For example, the UV lamp 140 may be or include a 300W bulb configured to emit UV light having a wavelength of 222 nm.

As shown, the reflector 142 includes flat, upright sidewalls 144 connected together by an upper curved wall 146. The upper curved wall 146 may bow outwardly away from the UV lamp 140. For example, the upper curved wall 146 may have a parabolic cross-section and/or profile.

It has been found that the straight, linear sidewalls 144 provide the desired reflection and/or focusing of the UV light emitted from the UV lamp 140 toward and onto the desired location. Alternatively, the side walls 144 may not be straight and flat.

Fig. 10 illustrates a perspective end view of the UV lamp 140 and reflector 142 of a disinfection head according to an embodiment of the present disclosure. The reflector 142 shown in fig. 10 is similar to the reflector 142 shown in fig. 9, except that the side walls 144 may be angled outwardly from the upper curved wall 146.

Fig. 11 illustrates a perspective end view of the UV lamp 140 and reflector 142 of a disinfection head according to an embodiment of the present disclosure. In this embodiment, the side walls 144 may be curved according to the curvature of the upper curved wall 146.

Fig. 12 illustrates a top perspective view of the disinfection head 106. Fig. 13 illustrates a bottom perspective view of the disinfection head 106. Fig. 14 illustrates an axial cross-sectional view of the disinfection head 106 through line 14-14 of fig. 12. Referring to fig. 12-14, air 150 is configured to be drawn into the disinfection head 106 through one or more openings 152 (or simply open chambers) of the shroud 112. Air 150 is drawn into the disinfection head 106, for example, via a vacuum generator within the backpack assembly 104 (shown in fig. 1). Air 150 is drawn into the shroud 112 and cools the UV lamp 140 as it passes over and around the UV lamp 140. Air 150 enters port 120 and enters hose 122, such as within an air tube within hose 122. The air 150 not only cools the UV lamps 140, but also removes ozone within the shroud 112 that may be generated by operation of the UV lamps 140. The air 150 may be drawn into an air filter, such as an activated carbon filter, within the backpack assembly 104.

In at least one embodiment, portable sanitizing system 100 can also include an alternative ozone mitigation system. By way of example, the ozone abatement system may be disposed in the shroud 112 or another portion of the system, and may include an inert gas bath (such as in U.S. patent No.10,232,954) or a face inert gas system (face inert gas system).

In particular, referring to FIG. 13, a bumper 153 may be secured to an exposed lower circumferential edge 155 of the shroud 112. The bumper 153 may be formed of an elastomeric material (e.g., rubber), another elastomeric material, open or closed cell foam, and/or the like.

The throttle control unit 510 may enable application programs as described herein. The application may broadcast an audio file for the selected item to be sterilized.

As an example, the throttle control unit 520 may output a throttle signal 516, the throttle signal 516 including, for example, commands and throttle for a central flight console on the flight deck. Throttle signal 516 is received by user device 502. The throttle signal 516 includes an audio file that provides guidance to the user for the sweep or otherwise moving the wand assembly 102. The total setron time is intended to give a specific dose throughout the center stack to effectively and efficiently sterilize the center stack. For example, the command may indicate (via text or audio signals) that "sweep forward at a uniform rate, starting from the most trailing portion of the console, takes 10 seconds to reach the front of the console". Next, the instructions may indicate via audio broadcast "start: 10. 9, 8, 7,6, 5, 4, 3, 2, 1. Console end "to count down. Next, the instructions may indicate "move the wand to the right side armrest. The metronome-type beat may be played at the end of the scanning cycle with a cymbal impact sound effect or other suitable sound per second.

Still referring to fig. 24-27, certain embodiments of the present disclosure provide a method of pacing UV sterilization of a predetermined surface. The method includes calculating a rod speed. The rod speed was calculated by: the user selects an item to be sterilized via the user device and the pacing control unit 510 retrieves the pacing data 514 associated with the item from the pacing database 512. The governing data 514 includes the rod speed. The throttle data 514, which is output by the throttle control unit 512, provides audio prompts (as broadcast through the speaker 508) related to the rate at which the wand assembly 102 is moving and may provide feedback (e.g., audio instructions for the duration of the scan), so that the user can maintain the rate.

In at least one embodiment, the audio prompt may be or otherwise include a series of audio files to provide voice instructions and pacing for the area to be cleaned, or may include a tone such as metronome beats and/or cymbal sounds to indicate the end of the period of the setron. The audio file may be loaded into a computer program (e.g., a mobile application program) to act as an audio coach to instruct the user how long to keep the UV wand on the area for sterilization. The computer program may include a mobile application or other computer program that manages audio files.

In at least one embodiment, the wand speed is calculated by inputting known parameters, such as distance to the surface, irradiance of the wand, sterilization energy required to sterilize the surface, wand length and wand width, to calculate the time required to sterilize the surface.

Fig. 28 illustrates a flow chart of a UV pacing method according to an embodiment of the present disclosure. Referring to fig. 24 and 28, at 600, an individual selects an item on user device 504 to be sterilized by UV light. At 602, the pacing control unit 510 retrieves pacing data 514 relating to the items to be sterilized from the pacing database 512. At 604, throttle control unit 510 outputs a throttle signal 516 to user device 502, throttle signal 516 including throttle information for the item to be sterilized and one or more audio prompts. At 606, the user device 502 displays pacing information and/or broadcasts one or more audio prompts that assist the user in moving the wand assembly 102 to effectively and efficiently sterilize the item.
