[0002] This application relates to and claims priority to U.S. Provisional Patent Application No. 63 / 055,389, filed July 23, 2020, entitled “Systems and Methods of Verifying Effective Motion of a Wand Assembly of an Ultraviolet (UV) Light Sanitizing System”. Technical Field

[0003] The embodiments disclosed in this subject matter generally relate to disinfection systems, and more specifically to systems and methods for verifying that the movement of a cane assembly of a disinfection system is sufficient to disinfect the surface of a component. Background Technology

[0004] Vehicles such as commercial aircraft are used to transport passengers between different locations. Systems have been developed for sterilizing or disinfecting surfaces inside aircraft, for example, using ultraviolet light, or UV light. For disinfecting structural surfaces, known UV light sterilization methods emit broad-spectrum UVC light onto the structure.

[0005] A portable disinfection system with a cane assembly is being developed for disinfecting components. The cane assembly of the portable disinfection system includes a UV lamp configured to emit UV light. Typically, an operator moves the cane assembly over the surface of the component to disinfect that surface. However, individuals are often unaware whether the cane assembly is being moved too fast or too slow to effectively and efficiently disinfect the surface.

[0006] Manual processes for disinfecting surfaces using handheld devices typically exhibit varying degrees of consistency. Summary of the Invention

[0007] A system and method are needed to verify that the movement of a cane assembly with a UV lamp is sufficient to disinfect the surface of a component. Furthermore, a system and method are needed to ensure that the correct dose of UV light is delivered to the surface for effective disinfection.

[0008] In view of these needs, certain embodiments disclosed in this subject matter provide a system including a cane assembly having a sterilization head having an ultraviolet lamp (UV lamp) configured to emit UV light to sterilize the surfaces of components. The cane assembly also includes a first monitored component. The system also includes a second monitored component. A verification control unit communicates with one or both of the first and second monitored components. The verification control unit is configured to detect the speed of the cane assembly based on a comparison of the first monitored component with respect to the second monitored component.

[0055] The foregoing overview and the following detailed description of certain embodiments will be better understood when read in conjunction with the accompanying drawings. As used herein, elements or steps stated in the singular and following the word "a" or "an" should be understood to not necessarily exclude multiple elements or steps. Furthermore, references to "an embodiment" are not intended to exclude the existence of other embodiments that also include the described features. Moreover, unless explicitly stated to the contrary, embodiments that "comprise" or "have" one or more elements having a particular condition may include other elements that do not have that condition.

[0056] Some embodiments of this subject matter disclose a disinfection system and method comprising an ultraviolet lamp (e.g., an excimer lamp) that emits UV light in the far-UV spectrum (e.g., UV light with a wavelength of 222 nanometers (nm), which can neutralize (e.g., kill) microorganisms (e.g., viruses and bacteria) without posing a threat to humans). In one example, the UV lamp can be used in an interior cabin to purify and kill pathogens. The embodiments disclosed in this subject matter provide safer and more effective hygiene compared to some known UV systems. The UV lamp can be used in portable or stationary disinfection systems. For example, a portable or stationary system can be used to operate the UV lamp to emit disinfecting UV light with a wavelength of 222 nm. In at least one other embodiment, the UV lamp emits UV light with a wavelength outside the far-UV spectrum. For example, the UV lamp can be configured to emit UV light within the UVC spectrum (e.g., a wavelength of 254 nm).

[0057] Certain embodiments disclosed in this subject matter provide a system for verifying the speed of a cane assembly to ensure the correct dose of disinfecting light is delivered to a surface. The system includes a radio frequency (RF) receiver located at a fixed location (e.g., at the operator's location or in a fixed location within the environment, such as inside a vehicle). An RF transmitter is disposed on the cane assembly, such as the disinfection head of the cane assembly. A verification control unit (e.g., one or more processors) is located in a backpack or case of the portable disinfection system. Memory communicates with or is part of the processor. The speed of the cane assembly is determined by integrating the position of the disinfection head relative to the fixed location. The operator is aware of the actual cane speed through indicator activity, which may include a pacing light or audio tone on the cane assembly.

[0058] Alternatively, the system may include a camera at a fixed location and an optical target on the cane. Alternatively, an infrared light source may be located at a fixed location, and the infrared optical target may be located on the cane assembly. Alternatively, a light detection and ranging (LIDAR) detector may be located at a fixed location, and the LIDAR optical target may be located on the cane assembly. Alternatively, an accelerometer may be placed on the cane assembly.

[0059] In at least one embodiment, the speed at which the cane assembly will be moved is determined by the distance of the cane, which has a specific lamp power, from the surface. Once the operator selects a distance (e.g., 4 inches (10.16 cm) from the sterilization surface), the system determines the speed required to deliver the correct dose of UV light.

[0060] In at least one embodiment, the predetermined dose of UV light is determined by the lamp power, the distance to the target, and the exposure time. The speed of movement of the cane assembly determines the exposure time.

[0061] The position of a cane assembly relative to a fixed point (e.g., on the operator) can be determined using one or more of the following methods: RF transmitter triangulation using an RF transmitter in the cane and a receiver located in the cane operator's backpack, chest strap, or other wearable device; RF transmitter triangulation using an RF transmitter located in the cane operator's backpack, chest strap, or other wearable device and an RF receiver in the cane assembly; optical triangulation using a camera located in the cane operator's chest strap (or other wearable device) and an optical target visible on the cane; optical triangulation using a solid-state LiDAR located in the cane operator's chest strap (or other wearable device) and a LiDAR optical target visible on the cane assembly; and / or optical triangulation using a solid-state infrared light source located in the cane operator's chest strap (or other wearable device) and an infrared optical reflector visible on the cane.

[0062] The position of the sterilization head relative to the fixed point on the vehicle or building can be determined by using the RF receiver in the cane assembly and the transmitter at a fixed location on the vehicle or building through RF transmitter triangulation. The velocity of the sterilization head can be directly determined by integrating the acceleration within the sterilization head using an accelerometer on the sterilization head.

[0063] The operator can use one or more of the following to determine the actual speed of the cane assembly relative to the desired speed: pacing lights on the cane assembly that illuminate with different colors and flashing rates depending on whether the speed is correct, too fast, or too slow; and / or audio pitches that change the sound and pulse rate depending on whether the speed is correct, too fast, or too slow.

[0064] Figure 1 A perspective view of a portable disinfection system 100 worn by an individual 101 according to an embodiment disclosed in this subject matter is shown. The portable disinfection system 100 includes a cane assembly 102 coupled to a backpack assembly 104, which is removably secured to the individual via a shoulder strap 105. The cane assembly 102 includes a disinfection head 106 coupled to a handle 108. In at least one embodiment, the disinfection head 106 is movably coupled to the handle 108 via a coupler 110.

[0065] In at least one other embodiment, the portable disinfection system 100 may not be worn by the individual 101. For example, the portable disinfection system 100 may include a housing assembly configured to open and close. The housing assembly may store a cane assembly 102 when not in use. The housing assembly may be opened to allow removal and manipulation of the cane assembly 102.

[0066] like Figure 1As shown, the cane assembly 102 is in the stowed position. In this stowed position, the cane assembly 102 is removably secured to a portion of the backpack assembly 104, for example, by one or more rails, clips, latches, straps, chains, etc.

[0067] In at least one other embodiment, the cane assembly 102 is stored within a housing assembly in a stowed position. For example, the cane assembly 102 in the stowed position is housed within a closed housing assembly. The housing assembly can be opened to allow removal and deployment of the cane assembly 102.

[0068] Figure 2 A perspective side-top view of a cane assembly 102 according to an embodiment disclosed herein is shown. A sterilizing head 106 is coupled to a handle 108 via a coupler 110. The sterilizing head 106 includes a shield 112 having an outer cover 114 extending from a proximal end 116 to a distal end 118. As described herein, the shield 112 houses a UV lamp.

[0069] Optionally, the cane assembly 102 may include a sterilization head 106 attached to a fixed handle. Furthermore, the cane assembly 102 may have a different size and shape than those shown in the illustration.

[0070] Port 120 extends from proximal end 116. Port 120 is coupled to hose 122, which in turn is coupled to backpack assembly 104 (e.g., ...). Figure 1 (As shown). The flexible hose 122 houses wires, cables, wiring, or similar components that will connect the backpack assembly 104 (as shown). Figure 1 The power source or power supply device (e.g., one or more batteries) in the shield 112 is coupled to the UV lamp 140 within the shield 112. Alternatively, wires, cables, wiring, or similar components may be external to the hose 122. In at least one embodiment, the hose 122 may also house an air delivery line (e.g., an air tube) that fluidly couples the interior chamber of the shield 112 to a blower, vacuum generator, air filter, and / or the like in the backpack assembly 104.

[0071] Coupler 110 is secured to the outer cover 114 of housing 112, for example, near the proximal end 116. Coupler 110 may include a retaining beam 124 secured to the outer cover 114, for example, by one or more fasteners, adhesives, and / or the like. Extension beam 126 extends outward from retaining beam 124, thereby spaced the handle 108 from housing 112. Bearing assembly 128 extends from extension beam 126 opposite to retaining beam 124. Bearing assembly 128 includes one or more bearings, rails, and / or the like to allow handle 108 to translate linearly relative to coupler 110 in the direction of arrow A, and / or pivot about a pivot axis in the direction of arc B. Optionally, the fixed beam 124 may include a bearing assembly that allows the sterilization head 106 to translate in the direction of arrow A and / or rotate (e.g., rotate) in the direction of arc B, which is attached to or replaces the handle 108 coupled to the bearing assembly 128 (e.g., the handle 108 may be fixed to the coupler 110).

[0072] In at least one other example, the cane assembly 102 does not include the coupler 110. Instead, for example, the handle 108 may be attached to the shield 112.

[0073] In at least one example, the handle 108 includes a rod, post, beam, or similar element 130 that may be longer than the guard 112. Optionally, the rod 130 may be shorter than the guard 112. One or more handles 132 are attached to the rod 130. The handles 132 are configured for personal gripping or holding. The handles 132 may include ergonomic tactile features 134.

[0074] Alternatively, the cane assembly 102 may have a different size and shape than those shown in the figure. For example, the handle 108 may be fixed relative to the guard 112. Furthermore, the handle 108 may not be configured to move relative to itself and / or the guard 112. For example, the handle 108 and the guard 112 may be integrally molded and formed as a single unit.

[0075] In at least one example, the cane assembly 102 is not coupled to the backpack assembly. For example, the cane assembly 102 is a separate unit with a power source (e.g., one or more batteries). As another example, the cane assembly 102 is coupled to the case assembly.

[0076] Figure 3 Show Figure 2 A perspective rear view of the cane assembly 102. Figure 4 Show Figure 2 A perspective side view of the cane assembly 102. (Refer to...) Figure 3 and Figure 4The handle 108 can be pivotally coupled to the coupler 110 via a bearing 136 having a pivot shaft 138. The handle 108 can be further configured to linearly translate in and out of the bearing 136. For example, the handle 108 can be configured to retract and extend. Optionally or alternatively, in at least one embodiment, the handle 108 may include a telescopic body that allows the handle 108 to extend outward and retract inward. In at least one other embodiment, the handle 108 may not be configured to move, extend, retract, etc., relative to the cover 112.

[0077] Figure 5 A perspective view of a portable disinfection system 100 in a compact deployment location, according to an embodiment disclosed in this subject matter. Figure 5 As shown, the cane assembly 102 is separated from the backpack assembly 104 (as shown). Figure 1 (As shown) Remove to the compact deployment position. The hose 122 connects the cane assembly 102 to the backpack assembly 104. In the compact deployment position, the disinfection head 106 is fully retracted relative to the handle 108.

[0078] Figure 6 A perspective view of a portable disinfection system 100 having a disinfection head 106 in an extended position, according to an embodiment disclosed in this subject matter, is shown. To extend the disinfection head 106 relative to a handle 108, the disinfection head 106 slides outward relative to the handle 108 in the direction of arrow A' (or the handle 108 slides backward relative to the disinfection head 106). As described above, the disinfection head 106 is capable of linear translation relative to the handle 108 in the direction of arrow A' via a coupler 110. Figure 6 As shown, the outward extension of the disinfection head 106 allows the portable disinfection system 100 to easily reach distant areas. Alternatively, the disinfection head 106 may not be linearly translated relative to the handle 108.

[0079] Figure 7 A perspective view of a portable sterilization system 100 having a sterilization head 106 in an extended position and a handle 108 in an extended position, according to an embodiment disclosed in this subject matter, is shown. To reach further, the handle 108 may be configured, for example, to translate linearly via a telescopic portion, allowing the sterilization head 106 to reach further outwards. Alternatively, the handle 108 may not be configured to extend and retract.

[0080] In at least one embodiment, the handle 108 may include a lock 109. The lock 109 is configured to selectively operate to secure the handle 108 in a desired extended (or retracted) position.

[0081] Figure 8A perspective view of a portable disinfection system 100 having a disinfection head 106 rotatable relative to a handle 108, according to an embodiment disclosed in this subject matter, is shown. As described above, the disinfection head 106 is configured to rotate relative to the handle 108 via a coupler 110. Rotating the disinfection head 106 relative to the handle 108 allows the disinfection head 106 to be moved to a desired position and to sweep over or reach areas that would be difficult to reach if the disinfection head 106 were rigidly fixed to the handle 108. Alternatively, the disinfection head 106 may not be rotatable relative to the handle 108.

[0082] Figure 9 This image shows a perspective end view of the UV lamp 140 and reflector 142 of a sterilization head 106 according to an embodiment disclosed in this subject matter. The UV lamp 140 and reflector 142 are fixed within a protective cover 112 of the sterilization head 106 (e.g., as shown in the image). Figure 2 (As shown). In at least one embodiment, the reflector 142 is attached to the bottom side 141 of the shield 112, for example, by one or more adhesives. As another example, the reflector 142 is an integral part of the shield 112. For example, the reflector 142 may be or otherwise provide the bottom side 141 of the shield 112. The reflector 142 provides a reflective surface 143 (e.g., formed of Teflon, a mirror surface, and / or the like) configured to reflect UV light emitted by the UV lamp 140 outwards. In at least one example, the shield 112 may be or comprise a housing formed of fiberglass, and the reflector 142 may be formed of Teflon, which provides 98% reflectivity. In at least one embodiment, the reflector 142 may be a multi-piece reflector.

[0083] The reflector 142 may extend along the entire length of the bottom side 141 of the shield 112. Alternatively, the reflector 142 may extend along a length less than the entire length of the bottom side 141 of the shield 112.

[0084] UV lamp 140 may extend along its entire length (or substantially along its entire length, e.g., between ends 116 and 118). UV lamp 140 is secured to reflector 142 and / or shield 112 by one or more mounting elements (e.g., brackets). UV lamp 140 includes one or more UV light emitters, such as one or more bulbs, light-emitting elements (e.g., light-emitting diodes), and / or the like. In at least one embodiment, UV lamp 140 is configured to emit UV light in the far UV spectrum (e.g., wavelengths between 200 nm and 230 nm). In at least one embodiment, UV lamp 140 is configured to emit UV light with a wavelength of 222 nm. For example, UV lamp 140 may be or include a 300W bulb configured to emit UV light with a wavelength of 222 nm. Alternatively, UV lamp 140 may be configured to emit UV light in other portions of the UV spectrum (e.g., the UVC spectrum, e.g., with a wavelength of 254 nm).

[0085] As shown, reflector 142 includes flat, upright sidewalls 144 connected together by an upper curved wall 146. The upper curved wall 146 can be curved outward away from the UV lamp 140. For example, the upper curved wall 146 can have a parabolic cross section and / or profile.

[0086] It has been found that straight, linear sidewalls 144 provide the desired reflection and / or convergence of UV light emitted from UV lamp 140 toward and to the desired location. Alternatively, sidewalls 144 may not be linear and flat.

[0087] Figure 10 A perspective end view of the UV lamp 140 and reflector 142 of the sterilization head according to an embodiment disclosed in this subject matter is shown. Figure 10 The reflector 142 shown is similar to Figure 9 The reflector 142 shown is different in that the sidewall 144 can be tilted outward from the upper curved wall 146.

[0088] Figure 11 A perspective end view of the UV lamp 140 and reflector 142 of the sterilization head according to an embodiment disclosed in this subject matter is shown. In this embodiment, the sidewall 144 can be bent according to the curvature of the upper curved wall 146.

[0089] Figure 12 A perspective top view of the sterilization head 106 is shown. Figure 13 A perspective bottom view of the sterilization head 106 is shown. Figure 14 Showing through Figure 12 The axial cross-sectional view of the sterilization head 106 taken from line 14-14. (Refer to...) Figures 12-14Air 150 is configured to be drawn into the sterilization head 106 through one or more openings 152 (or simply an open chamber) of the shield 112. Air 150 is, for example, via backpack assembly 104 ( Figure 1 The vacuum generator (shown in the diagram) draws air into the sterilization head 106. Air 150 is drawn into the shroud 112 and cools the UV lamp 140 as it passes through and surrounds it. The air 150 proceeds into the port 120 and enters the hose 122, such as the air tube within the hose 122. The air 150 not only cools the UV lamp 140 but also removes ozone that may be generated by the operation of the UV lamp 140 within the shroud 112. The air 150 may be drawn into an air filter (e.g., an activated carbon filter) within the backpack assembly 104.

[0090] In at least one embodiment, the portable disinfection system 100 may also include an alternative ozone mitigation system. As an example, the ozone mitigation system may be disposed in the shield 112 or in another part of the system, and may include an inert gas bath or a surface inert gas system, such as described in U.S. Patent No. 10,232,954.

[0091] Reference Figure 13 Specifically, the shock absorber 153 can be fixed to the exposed lower peripheral edge 155 of the shield 112. The shock absorber 153 can be formed of a resilient material, such as rubber, another elastic material, open-cell or closed-cell foam, and / or the like. In the event of accidental contact between the sterilization head 106 and the surface, the shock absorber 153 protects the sterilization head 106 from damage. The shock absorber 153 also protects the surface from damage.

[0092] The openings 152 may be spaced apart around the lower surface of the shield 112 so that they do not provide direct view of the UV lamp 140. For example, the openings 152 may be positioned below the portion spaced apart from the UV lamp 140.

[0093] Reference Figure 14Specifically, the sterilization head 106 may include a cover plate 154 below the UV lamp 140. The cover plate 154 may be formed of, for example, glass and may be configured to filter UV light emitted by the UV lamp 140. The UV lamp 140 may be fixed in an inner cavity 156 defined between the reflector 142 and the cover plate 154. In at least one embodiment, the cover plate 154 is or includes a far-UV bandpass filter. For example, the cover plate 154 may be a 222nm bandpass filter that filters the UV light emitted by the UV lamp 140 to a wavelength of 222nm. In this way, the UV light emitted from the sterilization head 106 can be emitted at a wavelength of 222nm. In at least one other embodiment, the cover plate 154 may be a 254nm bandpass filter that filters the UV light emitted by the UV lamp 140 to a wavelength of 254nm. In this way, the UV light emitted from the sterilization head can be emitted at a wavelength of 254nm.

[0094] Reference Figure 13 and Figure 14 The rim 157 (e.g., a 0.020-inch thick titanium rim) can connect the cover 154 to the shield 112. The rim 157 can distribute impact loads passing through it and / or around it.

[0095] In at least one embodiment, a ranging light-emitting diode (LED) 159 may be disposed near the end of the UV lamp 140. The ranging LED 159 may be used to determine the desired distance to, for example, a structure to be disinfected. In at least one embodiment, the ranging LED 159 may be disposed on or within the rim 157 and / or cover plate 154. As another example, the disinfection head 106 may be configured for distance guidance, as disclosed in U.S. Provisional Application No. 63 / 027,869, filed May 20, 2020, the entire contents of which are incorporated herein by reference.

[0096] Figure 15 A perspective end view is shown of a UV lamp 140 secured to a mounting bracket or clamp 160 according to an embodiment disclosed in this subject matter. Each end of the UV lamp 140 may be coupled to the mounting bracket or clamp 160, which secures the UV lamp 140 to a protective cover 112 (e.g., Figures 12-14 (As shown). A buffer (e.g., a thin (e.g., 0.040-inch) silicon sheet) may be disposed between the end of the UV lamp 140 and the bracket 160. Alternatively, the UV lamp 140 may be secured to the shield 112 by means of a bracket or clamp of a different size and shape than those shown in the illustration. As another example, the UV lamp 140 may be secured to the shield 112 by means of adhesives, fasteners and / or the like.

[0097] Figure 16An exploded perspective view of a backpack assembly 104 according to an embodiment disclosed in this subject matter is shown. The backpack assembly 104 includes a front wall 170 coupled to a rear shell 172, a base 174, and a top wall 176. An inner cavity 178 is defined between the front wall 170, the rear shell 172, the base 174, and the top wall 176. One or more batteries 180 (e.g., rechargeable lithium batteries) are housed in the inner cavity 178. An air generation subsystem 182 is also housed in the inner cavity 178. The air generation subsystem 182 is connected to a hose 122 (e.g., as shown in the image). Figure 2 The air ducts within (shown) are in fluid communication. The air generation subsystem 182 may include airflow devices, such as a vacuum generator, a blower, etc. The airflow devices are configured to generate airflow to cool the UV lamp, draw air from the sterilization head 106 into the backpack assembly 104 and exhaust it through an exhaust duct, draw in or otherwise remove generated ozone from the shield 112, etc.

[0098] One or more air filters 183 (e.g., carbon filters) are located within backpack assembly 104. Air filters 183 are in communication with air ducts or other such delivery lines that transmit air through hose 122 into backpack assembly 104. Air filters 183 are configured to filter air drawn into backpack assembly 104 from shroud 112. For example, air filters 183 may be configured to remove, deactivate, or otherwise neutralize ozone.

[0099] The battery 180 and / or power source within the backpack assembly 104 power the UV lamp 140 of the sterilization head 106 (e.g., as...). Figure 2 (As shown) provides operating power. The top wall 176 (e.g., a top cover) may be removably coupled to the front wall 170 and the rear shell 172. For example, the top wall 176 may be removed to provide access to the battery 180 (e.g., to remove the battery and / or recharge it). Additional space may be provided within the backpack assembly 104 for storing a supply, additional batteries, additional components, etc. In at least one embodiment, the front wall 170, rear shell 172, base 174, and top wall 176 may be formed of glass fiber epoxy resin.

[0100] Figure 17 A perspective front view of a shoulder strap 105 coupled to a backpack assembly 104 according to an embodiment disclosed in this subject matter is shown. The shoulder strap 105 may include shoulder straps 190 and / or straps or cords 192 for the wrists or hips, which allow an individual to comfortably wear the backpack assembly 104.

[0101] Reference Figures 1-17In operation, an individual wearing backpack assembly 104 can walk through an area. When a structure to be disinfected is found, the individual can position and grip handle 108 and position disinfection head 106 as needed, for example, by extending and / or rotating disinfection head 106 relative to handle 108. The individual can then engage, for example, an activation button on handle 108 to activate UV lamp 140 to emit disinfecting UV light onto the structure. As UV lamp 140 is activated, air 150 is drawn into shield 112 to cool UV lamp 140 and transfer any ozone generated to backpack assembly 104, where it is filtered by air filter 183.

[0102] The extendable cane assembly 102 allows the disinfection head 106 to reach distant areas, such as across an entire group of three passenger seats in a row from the interior of a commercial aircraft.

[0103] Figure 18 The ultraviolet light spectrum is shown. (Refer to...) Figures 1-18 In at least one embodiment, the disinfection head 106 is configured to emit disinfection UV light (via operation of the UV lamp 140) in the far UV spectrum (e.g., between 200 nm and 230 nm) and / or the UVC spectrum. In at least one embodiment, the disinfection head 106 emits disinfection UV light with a wavelength of 222 nm. In at least one other embodiment, the disinfection head 106 emits disinfection UV light with a wavelength of 254 nm.

[0104] Figure 19 A schematic block diagram of a cane speed verification system 200 according to an embodiment disclosed in this subject matter is shown. The cane speed verification system 200 includes a cane assembly 102 having a sterilization head 106. In at least one embodiment, a first monitored member 202 is part of or attached to the cane assembly 102.

[0105] The second monitored component 204 is separate from and distinct from the cane assembly 102. The second monitored component 204 can be fastened to a fixed structure, such as within the interior of a vehicle. Alternatively, the second monitored component 204 can be fastened to a backpack assembly 104 worn by the operator (e.g.,...). Figure 1 As shown in the diagram), housing assemblies, wearable devices, etc. (e.g., on or inside them).

[0106] The verification control unit 206 communicates with the memory 208, for example, via one or more wired or wireless connections. The memory 208 may be part of the verification control unit 206 or may be separate from and distinct from it. In at least one embodiment, the verification control unit 206 and the memory 208 are located within the backpack assembly 104, the case assembly, or the cane assembly 102. In at least one other embodiment, the verification control unit 206 and the memory 208 are located remotely from the backpack assembly 104, the case assembly, the cane assembly 102, etc. For example, the verification control unit 206 and the memory 208 may be located within a portion of the interior compartment of a vehicle.

[0107] The verification control unit 206 communicates with the first monitored component 202 and / or the second monitored component 204, for example, via one or more wired or wireless signals. For example, the verification control unit 206 receives signals output from the first monitored component 202 and / or the second monitored component 204 to determine the moving speed of the disinfection head 106.

[0108] In at least one embodiment, the cane assembly 102 includes, for example, an indicator 210 on a portion of the cane assembly 102 (e.g., on the sterilization head 106 or on a handle attached to the sterilization head 106). The indicator 210 includes one or more lights 212 and / or a speaker 214. As another example, the indicator 210 includes a screen displaying text, graphics, or video. As yet another example, the indicator 210 may be a vibration device configured to provide feedback through vibration.

[0109] During operation, memory 208 stores pacing data for the cane assembly 102. For example, the pacing data includes the pacing speed of the disinfection head 106 for various distances from the surface to be disinfected, the power of the UV lamp 140, the specific wavelength of the emitted UV light, the effective dose time, etc.

[0110] The cane assembly 102 is operated by moving the disinfection head 106 above the surface to be disinfected. The distance of the disinfection head 106 from the surface is detected by one or more sensors, such as those disclosed in U.S. Provisional Application No. 63 / 027,869. The sensors communicate with a verification control unit 206. In this way, the verification control unit 206 determines the distance of the disinfection head 106 from the surface based on signals output from the sensors.

[0111] As the disinfection head 106 moves, the first monitored member 202 moves relative to the second monitored member 204. The verification control unit 206 detects the motion from one or more signals output from one or both of the first monitored member 202 and / or the second monitored member 204. In this way, the verification control unit 206 determines the speed of movement of the cane assembly 102 relative to the surface.

[0112] The verification control unit 206 then compares the detected speed of the cane assembly 102, the distance of the cane assembly 102 from the surface, the type of emitted UV light, and the power of the emitted UV light with pacing data stored in the memory 208. For a specific UV light and its emission power, the pacing data indicates the correct speed for proper disinfection of the surface at the detection distance. Based on the comparison between the detected speed and the pacing data, the verification control unit 206 determines whether the actual speed of the cane assembly 102, detected according to one or more signals received from one or both of the first monitored member 202 and / or the second monitored member 204, is sufficient to disinfect the surface. If the actual speed of the cane assembly 102 is correct (e.g., determined to be equal to the correct speed or within an acceptable range corresponding to the correct speed), the verification control unit 206 outputs an indication signal to the cane assembly 102 indicating the correct speed. The indicator 210 can indicate the correct speed by the corresponding light energy (e.g., green light) emitted by one or more lights 212 and / or by an audio signal emitted by a speaker 214. As another example, indicator 210 includes a screen that displays text, graphics, or video about the speed of cane assembly 102.

[0113] However, if the actual speed of the cane assembly is too fast, thus providing insufficient disinfection (e.g., determined to be greater than the correct speed but not within the acceptable range corresponding to the correct speed), the verification control unit 206 outputs an indication signal to the cane assembly 102 indicating that the actual speed is too fast. The indicator 210 can indicate the speed by corresponding light energy (e.g., red light) emitted by one or more lamps 212 and / or by an audio signal emitted by a speaker 214.

[0114] However, if the actual speed of the cane assembly is too slow, thus providing inefficient disinfection (e.g., determined to be less than the correct speed or outside the acceptable range corresponding to the correct speed), the verification control unit 206 outputs an indication signal to the cane assembly 102 indicating that the actual speed is too slow. The indicator 210 can indicate the slow speed via corresponding light energy (e.g., yellow light) emitted by one or more lamps 212 and / or an audio signal emitted by a speaker 214.

[0115] As described herein, system 200 includes a cane assembly 102, which includes a sterilization head 106 having a UV lamp 140 configured to emit UV light to sterilize the surfaces of components. The cane assembly also includes a first monitored component 202. System 200 also includes a second monitored component 204. A verification control unit 206 communicates with the first monitored component 202 and the second monitored component 204. The verification control unit 206 is configured to detect the speed of the cane assembly 102 based on a comparison of the first monitored component 202 with respect to the second monitored component 204.

[0116] As an example, the verification control unit 206 determines whether the speed of the cane assembly 102 is sufficient to disinfect the surface based on a comparison with pacing data stored in the memory 208. The verification control unit 206 outputs an alarm signal in response to the speed exceeding the limits defined in the pacing data. The verification control unit 206 outputs an appropriate speed signal in response to the speed being within the limits defined in the pacing data.

[0117] In at least one embodiment, the cane assembly 102 further includes an indicator 210 configured to indicate the speed state of the cane assembly 102. For example, the indicator 210 includes at least one light fixture 212 and / or a speaker 214.

[0118] In at least one embodiment, the result of the disinfection process performed by the cane assembly 102 can be recorded in memory 208. For example, if the verification control unit 206 determines that the disinfection process effectively disinfects one or more surfaces (e.g., determined by a pacing speed within a specific range), the effective disinfection process is stored in memory 208 and timestamped in memory 208.

[0119] The cane speed verification system 100 verifies the speed of the cane assembly 102 to ensure that the correct dose of disinfecting light (e.g., 222nm or 254nm UV light) is delivered to the surface. In at least one embodiment, the second monitored member 204 is a radio frequency (RF) receiver located in a fixed position, such as on the operator (e.g., on the backpack assembly 104) or in a fixed position in the environment (e.g., inside a vehicle). In this embodiment, the first monitored member 202 is an RF transmitter disposed on the cane assembly 102 (e.g., on the disinfection head 106). In at least one embodiment, the verification control unit 206 determines the speed of the cane assembly 102 by integrating the position of the disinfection head 106 relative to the fixed position. The operator learns the actual cane speed through indicator activity, which may include a pacing light or audio tone on the cane assembly 102. Alternatively, the first monitored member 202 is an RF receiver, while the second monitored member 204 is in a fixed position.

[0120] Alternatively, the second monitored component 204 is a camera in a fixed position, and the first monitored component 202 is an optical target on the cane assembly 102 (e.g., on the sterilization head 106). Alternatively, the second monitored component 204 is an optical target, and the first monitored component 202 is a camera.

[0121] Alternatively, the second monitored component 204 is an infrared light source in a fixed position, and the first monitored component 202 is an infrared optical target located on the cane assembly 102. Optionally, the second monitored component 204 is an infrared optical target, and the first monitored component 202 is an infrared light source.

[0122] Alternatively, the first monitored component 202 or the second monitored component 204 is a light detection and ranging (LIDAR) detector, and the other of the first monitored component 202 or the second monitored component 204 is a LIDAR optical target.

[0123] Alternatively, the first monitored component 202 may be an accelerometer on or within the cane assembly 102. In this embodiment, the second monitored component 204 may not be necessary. Instead, the verification control unit 206 detects the velocity of the cane assembly 102 via one or more signals output from the accelerometer.

[0124] In at least one embodiment, the speed of the cane assembly 102 is determined by the distance from the surface to the cane, which has a certain lamp power. Once the operator selects this distance (e.g., 4 inches (10.16 cm) from the sterilization surface), the verification control unit 206 determines the speed required to achieve the correct dose of UV light, as stored in memory 208 as step data.

[0125] In at least one embodiment, the predetermined dose of UV light is determined by the lamp power, the distance to the target, and the exposure time. The speed of the cane assembly 102 determines the exposure time.

[0131] Figure 20 A perspective view of a portable disinfection system 100 worn by an individual 101 according to an embodiment disclosed in this subject matter is shown. As shown, a first monitored component 202 is on the disinfection head 106 of a cane assembly 102. A second monitored component 204 may be in a backpack assembly 104 and / or a portion of a shoulder strap 105.

[0132] Figure 21 A flowchart illustrating a method for verifying the speed of a cane according to an embodiment disclosed in this subject matter is provided. (Refer to...) Figures 19-21 At 250, the verification control unit 206 detects the distance between the UV lamp 140 of the disinfection head 106 and the surface being disinfected, for example, via one or more distance sensors of the disinfection head 106. At 252, the verification control unit 206 detects the movement speed of the disinfection head 106 by comparing the change in position of the first monitored member 202 relative to the position of the second monitored member 204 over time.

[0133] At 254, the verification control unit 206 compares the detected distance and speed of the disinfection head 106 with pacing data stored in the memory 208. At 256, the verification control unit 206 determines whether the detected distance and speed are within an acceptable range of the pacing data (e.g., within + / - 5%). If not, the method continues from 256 to 258, at which point the verification control unit 206 outputs an alarm signal to the cane assembly 102. At 260, the alarm signal is indicated on the indicator 210, which indicates the corresponding fast or slow speed.

[0134] However, if the verification control unit 206 determines that the detected distance and speed are within acceptable limits, the method continues from 256 to 262, at which point the verification control unit 206 outputs an appropriate speed signal to the cane assembly 102. At 264, the appropriate speed signal is indicated on the indicator 210, which indicates the corresponding appropriate speed for disinfection.

[0135] Figure 22 A perspective front view of an aircraft 310 according to an embodiment disclosed in this subject matter is shown. The aircraft 310 includes a propulsion system 312, which includes, for example, an engine 314. Optionally, the propulsion system 312 may include more engines 314 than shown.

The overhanging cargo container assembly 418 is configured to be pivotally opened to receive, for example, luggage and personal belongings carried by passengers.

[0147] As used herein, the term "outboard" refers to a position that is further away from the center longitudinal plane 422 of the inner compartment 400 compared to other components. The term "inboard" refers to a position that is closer to the center longitudinal plane 422 of the inner compartment 400 compared to other components. For example, the lower surface of PSU 414 may be outboard relative to cargo container assembly 418.
