Description

[Technical Field]

[0001] Examples of the present disclosure relate generally to sterilization systems such as those used to sterilize structures or areas within a vehicle, and more particularly to systems and methods for sterilizing components with ultraviolet (UV) light. [Background technology]

[0002] Vehicles, such as commercial aircraft, are used to transport passengers between various locations. In some instances, systems are currently being developed for disinfecting or otherwise sterilizing surfaces within aircraft using ultraviolet (UV) light. UV light disinfection systems generally include a UV lamp containing multiple UV light emitters. A UV lamp is formed by integrating various UV emitters into a single housing and coupling the UV emitters to separate power sources. As can be appreciated, a UV lamp can have multiple UV emitters. The process of manufacturing such UV lamps is time-consuming and labor-intensive. Furthermore, if one or more UV emitters fail, replacing them can also prove to be time-consuming and labor-intensive. Furthermore, in various situations, UV light disinfection is performed when an area is unoccupied. In some instances, restrooms within aircraft can be disinfected with UV light. However, such disinfection is generally not performed when individuals are present within the restroom. Furthermore, during operation, UV emitters can generate electromagnetic interference (EMI), which can affect the operation of the UV lamp and / or other devices.

[0005] The foregoing summary, as well as the following detailed description of specific embodiments, will be better understood when read in conjunction with the accompanying drawings. As used herein, an element or step described in the singular and preceded by the words "a" or "an" should be understood as not necessarily excluding a plurality of elements or steps. Furthermore, references to "one example" are not intended to be interpreted as excluding the existence of additional examples that also incorporate the recited features. Furthermore, unless expressly stated to the contrary, examples "comprising" or "having" an element or elements having a particular qualification may include additional elements without that qualification. Particular examples of the present disclosure provide a system for disinfecting (and in some examples, sterilizing, decontaminating, cleaning, etc.) one or more components. The system includes multiple modules coupled to each other to form a UV lamp. Each of the multiple modules includes one or more UV light emitters configured to emit UV light onto the components to disinfect the components. In at least one example, each of the modules also includes a power source coupled to the UV emitters. The modules may also include bandpass filters configured to filter the generated UV light from the UV emitters to desired wavelengths within the far-UV spectrum, the UVC spectrum, etc. In at least one example, different modules may emit UV light at different wavelengths. In some examples, a first module may emit UV light within the far-UV spectrum, and a second module coupled to the first module may emit UV light within the UVC spectrum. Multiple modules may be coupled together (in some examples, stacked, grouped, or otherwise connected to each other) as desired to provide greater UV coverage. Such configurations may be determined based on the size of the surfaces to be disinfected. The modules may be coupled together by adhesive, one or more mechanical connectors or fasteners, etc. The UV lamp formed by multiple modules may be customized to fit within a desired area. In this manner, the UV lamp is compact and can be configured to fit into small, confined spaces.In at least one example, the UV lamp is part of a wand assembly configured to be held by an operator. In at least one other example, the UV lamp is a fixture within a space, such as within a restroom. The UV lamp can be fixed at a predetermined location within the space. Optionally, the UV lamp is configured to be movable between a stowed position and a deployed position within the space. In at least one example, the system includes an infrared (IR) sensor in communication with the control unit. The IR sensor is configured to detect IR light, such as an IR light beam that can be emitted from an IR source and reflected by the IR sensor. During operation, the control unit also communicates with one or more UV light emitters. The control unit is configured to selectively activate and deactivate the UV light emitters in response to signals received from the IR sensor. In some examples, the control unit prevents activation of the UV light emitters and / or deactivates the UV light emitters in response to the IR sensor not detecting IR light. In some examples, the IR source and / or IR reflector can be positioned, such as in close proximity (in some examples, within one foot or less) to the restroom door. The IR sensor is configured to monitor the IR beam and detect a change when an occupant crosses a threshold. Additionally, the system may include a door sensor (e.g., a door Hall effect sensor) located on and / or proximate to the door to detect when the door is opened or closed. The control unit may also communicate with the door sensor and be configured to selectively activate and deactivate the UV light emitter in response to the IR sensor and / or one or more IR signals received from the door sensor. In at least one example, the control unit is configured to deactivate the UV light emitter when an area (e.g., a restroom) is occupied and activate the UV light emitter when the area is unoccupied. Integrating the IR sensor into the UV lamp reduces cost and installation time.Particular examples of the present disclosure provide sterilization systems and methods that include UV lamps (e.g., excimer lamps having one or more UV emitters, such as light-emitting diodes, light bulbs, etc.) that emit UV light in the far ultraviolet (UV) light spectrum, e.g., at a wavelength of 222 nm, to neutralize (e.g., kill) microorganisms (in some examples, viruses and bacteria) without posing a risk to humans. In some instances, the UV lamps emit UV light in the UVC spectrum at a wavelength of 254 nm. The UV lamps may be used in interior passenger compartments to decontaminate and kill pathogens. The UV lamps may be used in portable or stationary germicidal systems. In some examples, portable or stationary systems may utilize UV ​​lamps operating to emit germicidal UV light having wavelengths in the far-UV or UVC spectrum.

[0006] FIG. 1 shows a schematic block diagram of a system 100 for sterilizing a component 102 according to an example of the present disclosure. The component 102 may be any structure to be sterilized with UV light. In some examples, the component 102 may be a structure within a vehicle, a fixed building, etc. By way of example, the component 102 may be a passenger seat within a vehicle, a portion of a toilet (e.g., a toilet bowl, a sink, a door handle, and / or the like), a counter or other such surface within a kitchen or galley, etc. The system 100 includes a UV lamp 104 including multiple modules 106 coupled to one another. In some examples, the UV lamp 104 includes a first module 106a coupled to a second module 106b. Optionally, the UV lamp 104 may include three or more modules 106. Each module 106 includes one or more UV emitters 108 configured to emit UV light through an opening 112. The UV light emitters 108 can emit UV light within the far-UV spectrum, such as from 200 nanometers (nm) to 230 nm. In some examples, the UV light emitters can emit UV light at 222 nm. As another example, the UV light emitters 108 can emit UV light within the UVC spectrum, such as from 230 nm to 280 nm. In some examples, the UV light emitters can emit UV light at 254 nm. In at least one example, the UV light emitters 108 of the modules 106 emit UV light of the same wavelength. In at least one other example, the UV light emitters 108 of the modules 106 emit UV light of different wavelengths. In some examples, the UV light emitter 108a of the first module 106a emits UV light within the far-UV spectrum and the UV light emitter 108b of the second module 106b emits UV light within the UVC spectrum, or vice versa. The modules 106 are coupled together to form the light-emitting portion of the UV lamp 104. The modules 106 can be removably coupled to one another, thus providing a modular assembly that can be customized to a desired size, shape, and radiation capacity.Furthermore, if the module 106 needs repair, it can be removed from the UV lamp 104 and replaced in another module 106. Thus, the module 106 allows for efficient manufacturing and maintenance of the UV lamp 104. In at least one example, a portion of the module 106 is covered with one or more electromagnetic interference (EMI) shields 114. In some examples, the one or more UV light emitters 108 are surrounded by one or more surfaces with the EMI shields 114, and the openings 112 are not covered by the EMI shields 114. In at least one example, the EMI shields 114 are metal covers, such as foils formed of aluminum, steel, or the like, that cover the housing of the module 106 while leaving the openings 112 uncovered. Optionally, the module 106 does not include the EMI shields 114. The UV lamp 104 can be part of a wand assembly configured to be held by an individual. The wand assembly can be coupled to a backpack assembly, a case assembly, a cart, or the like. In at least one example, the wand assembly can be a stand-alone assembly not coupled to a backpack assembly, case assembly, cart, or the like. In at least one example, the UV lamp 104 can be a fixture within an area. In some examples, the UV lamp 104 can be fixed within a restroom, a galley, a kitchen, or various other areas. The UV lamp 104 can be fixed in a fixed position within the area. Optionally, the UV lamp 104 can be movable between a stowed position and a deployed position within the area. In at least one example, the system 100 also includes an infrared (IR) sensor 116 in communication with a control unit 118, such as via one or more wired or wireless connections. The control unit 118 also communicates with the UV light emitters 108 of the modules 106, such as via one or more wired or wireless connections. In at least one example, the UV lamp 104 includes the IR sensor 116 and / or the control unit 118. Optionally, the IR sensor 116 and / or the control unit 118 can be located remotely from the UV lamp 104.During operation, the control unit 118 selectively activates and deactivates the UV light emitters 108 based on IR signals emitted by and received from the IR sensor 116. In some examples, the IR sensor 116 is configured to receive the IR light signal 119 emitted by the IR source 120 directly from the IR source 120 or indirectly from a reflector that receives and reflects the IR light signal 119 from the IR source 120. When the IR sensor 116 receives the IR light signal 119, the IR sensor 116 outputs a sensed IR signal 122 to the control unit 118. Based on the received sensed IR signal 122, the control unit 118 activates the one or more UV light emitters 108 to emit UV light. However, if the IR sensor 116 does not receive the IR light signal 119 (e.g., if the IR light signal 119 is blocked by an individual), the IR sensor does not output the sensed IR signal 122 to the control unit 118. In response to not receiving the sensed IR signal 122, the control unit 118 deactivates the UV light emitter 108 so that it does not emit UV light. In at least one example, the activation switch 124 communicates with the control unit 118 via one or more wired or wireless connections, etc. The activation switch 124 can be fixed to the UV lamp 104. That is, the UV lamp 104 can include the activation switch 124. Optionally, the activation switch 124 can be located remotely from the UV lamp 104. When the activation switch 124 is engaged to activate the UV light emitter 108, the control unit 118 operates as described above (i.e., the control unit 118 selectively activates and deactivates the UV light emitter based on the signal received from the IR sensor 116). When the activation switch 124 is disengaged so that the UV light emitter 108 does not emit UV light, the control unit 118 maintains the UV light emitter 108 in a deactivated state even if the sensed IR signal 122 is received from the IR sensor 116. Optionally, the system 100 may not include an activation switch. In at least one example, the system 100 includes a UV lamp 104 having a UV light emitter 108, whether or not within a module 106.In some examples, the UV lamps 104 can be a single, non-modular assembly in communication with a control unit 118 that selectively activates and deactivates the UV light emitters 108 as described herein. In at least one other example, the system 100 does not include the IR sensor 116 or the IR source 120.

These are exemplary only and are therefore not intended to limit in any way the definition and / or meaning of such terms. In some examples, the control unit 118 can be or include one or more processors configured to control operations as described herein. The control unit 118 is configured to execute sets of instructions stored in one or more data storage units or elements (such as one or more memories) to process data.

The module 106 includes a housing 130 that holds a plurality of UV light emitters 108 configured to emit UV light through an opening 112. As illustrated, the module 106 includes a first plurality of UV light emitters 108a and a second plurality of UV light emitters 108b. The first plurality of UV light emitters 108a are housed within a first sub-housing 132, and the second plurality of UV light emitters 108b are housed within a second sub-housing 134 that is different from the first sub-housing 132. Each of the first sub-housing 132 and the second sub-housing 134 may include more or fewer UV light emitters 108 than are shown. Optionally, the module 106 may include a single sub-housing that holds all of the UV light emitters 108 shown in FIG. 2 . In at least one example, the module 106 includes a single UV light emitter 108 instead of multiple UV light emitters 108.

[0008] FIG. 3 illustrates a perspective bottom view of a first module 106a coupled to a second module 106b according to one example of the present disclosure. A first end 140 of the first module 106a is coupled to an opposite second end 142 of the second module 106b. Optionally, the first module 106a and the second module 106b can be coupled side-to-side. Another module (not shown in FIG. 3) can be coupled to the second end 144 of the first module 106a. Additionally, another module (not shown in FIG. 3) can be coupled to the first end 146 of the second module 106b. The modules 106a and 106b, as well as additional modules, can be stacked end-to-end and / or side-to-side as desired to provide various lighting patterns. The first module 106a and the second module 106b can be removably coupled to one another via, for example, one or more fasteners, adhesives, dovetail joints, lap joints, plug and socket connections, etc. In this manner, the first module 106a and the second module 106b can be efficiently coupled together. Furthermore, the first module 106a and the second module 106b can be disconnected, such as when one of the first module 106a or the second module 106b needs repair or is replaced.

[0009] FIG. 4 shows a perspective end view of module 106 according to an example of the present disclosure.

[0010] FIG. 5 shows a perspective top view of the module 106 of FIG.

[0011] FIG. 6 shows a perspective bottom view of the module 106 of FIG.

[0012] 4-6 , for clarity, certain exterior wall portions of the module 106 are not shown to show the internal components. In at least one example, the housing 130 includes a bracket 150 having a platform 152 extending between opposing side walls 154 and 156. The platform 152 includes a top surface 158 opposite a bottom surface 160. A partition wall 161 extends upwardly from the top surface 158. A first power chamber 162 is defined between the top surface 158, an inner surface 163 of the side wall 154, and a first side surface 165 of the partition wall 161. A second power chamber 164 is defined between the top surface 158, an inner surface 167 of the side wall 156, and a second side surface 169 (opposite the first side surface 165) of the partition wall 161. An emitter chamber 170 is defined between the lower surface 160, an inner surface 163 of the sidewall 154, and an inner surface 167 of the sidewall 156. A first power supply 172 is secured within the first power chamber 162. A second power supply 174 is secured within the second power chamber 164.

[0013] 1-6 , the first power source 172 and the second power source 174 may be batteries and / or power interfaces, connections, etc. configured to provide power to the UV light emitter 108. In at least one example, a frame 176 is secured within the emitter chamber 170 via one or more fasteners, adhesives, etc. The frame 176 holds the first sub-housing 132 and the second sub-housing 134. The UV light emitters 108 in the first sub-housing 132 and the second sub-housing 134 are electrically coupled to the first power source 172 and the second power source 174, respectively, via wiring passing through slots, channels, or other such openings formed in the platform 152. The platform 152 separates the frame 176 (including the UV light emitter 108) from the first power source 172 and the second power source 174. Furthermore, a partition wall 161 separates and insulates the first power source 172 from the second power source 174. In at least one example, first power supply 172 and second power supply 174 can be high voltage power supplies (e.g., 2 kV), so separation and insulation between them and relative to frame 176 ensures reliable and efficient operation. As shown, first power supply 172 and second power supply 174 are stacked above frame 176, which holds first sub-housing 132 and second sub-housing 134. Optionally, a single power supply can be used to power UV light emitters 108 in first sub-housing 132 and second sub-housing 134. In at least one example, bracket 150 may not include divider wall 161. In at least one other example, the power supply may be remote from module 106.

[0014] FIG. 7 shows a perspective bottom view of a bracket 150 according to one example of the present disclosure.

[0015] FIG. 8 shows a perspective top view of the bracket 150 of FIG.

[0017] 1 through 8 , in some examples, the passage 180 allows wiring to be routed between the UV light emitter 108 and the power sources 172 and / or 174. Optionally, the bracket 150 may not include the passage 180. Instead, in some examples, wiring may be routed around the edges of the platform 152. As shown, the side walls 154 and 156 may include inwardly sloping segments 155 and 157, respectively, that bound the first and second power chambers 162 and 164, respectively. The free ends of the inwardly sloping segments are inclined toward the partition wall 161. The inwardly sloping segments 155 and 157 provide a more compact bracket 150 that takes up less space. Optionally, the side walls 154 and 156 may also or alternatively include inwardly sloping segments. Alternatively, the bracket 150 may not include inwardly sloping segments.

The UV lamp 104 can include a battery 200, such as a 24V battery, that provides power to the power supplies of the modules 106. In at least one example, the battery 200 is configured to connect to a power cord 202 to be recharged.

[0024] 15 shows a bottom view of a UV lamp 104 having multiple modules 106 according to one example of the present disclosure. In this example, the UV lamp 104 may not include a battery. Instead, the UV lamp receives power from a power cord 202.

[0025] FIG. 16 shows a perspective side view of a wand assembly 210 including a UV lamp 104 according to one example of the present disclosure.

[0026] FIG. 17 shows a bottom view of the wand assembly of FIG.

[0027] 16 and 17 , the wand assembly 210 includes a germicidal head 212 coupled to a handle 213. The germicidal head 212 includes a shroud 214 that holds the UV lamp 104. The battery 200 may be held within the shroud 214. In at least one example, the germicidal head 212 is configured to move relative to the handle 213. In some examples, the germicidal head 212 may be extendable and / or rotatable relative to the handle 213. In at least one other example, the germicidal head 212 is fixed relative to the handle 213. The wand assembly 210 may include a UV lamp 104 having multiple modules 106, as described with respect to any of FIGS. 1-15 .

[0028] FIG. 18 shows a perspective interior view of a toilet 220 according to one example of the present disclosure. The toilet 220 may be located within the interior cabin of a vehicle, such as a commercial aircraft. The toilet 220 includes a toilet bowl 222 and a counter 224 having a sink 226 and a faucet 228. One or more UV lamps 104 are disposed within the toilet 220. The UV lamps 104 are configured as described with respect to any of FIGS. 1 through 15. The UV lamps 104 are configured to emit UV light to disinfect one or more components within the toilet 220, such as the toilet bowl 222, the counter 224, the sink 226, the faucet 228, the floor 230, and one or more walls 232. In at least one example, the UV lamps 104 can be fixed in place. In at least one other example, the UV lamps 104 can be configured to be movable. In some examples, the UV lamps 104 can be moved between a stowed position and a deployed position.

[0029] FIG. 19 shows a perspective interior view of a toilet 220 according to one example of the present disclosure.

[0030] 1 and 19 , in this example, the UV lamp 104 includes an IR sensor 116 that receives an IR light signal 119 from an IR source 120. The IR source 120 is configured to emit the IR light signal 119 through an area where an individual would be present if occupying the restroom 220. The IR sensor 116 may be aligned with the IR source 120 to receive the IR light signal 119 directly from the IR source 120. Optionally, the IR source 120 may be configured to emit the IR light signal 119 with a reflector, such as a mirror, that reflects the IR light signal 119 back to the IR source 120. The IR sensor 116 may be attached directly to the UV lamp 104, such as to a housing. In at least one example, the IR sensor 116 may be fixed to a module 106. In at least one example, multiple modules 106 include the IR sensor 116. In at least one other example, the IR sensor 116 is remote from the UV lamp 104. As shown, the IR sensor 116 can be affixed to an end or corner of the UV lamp 104. The IR sensor 116 is configured to receive an IR light signal 119 either directly from the IR source 120 or indirectly from the IR source 120 reflected from one or more reflectors 121. The IR light signal 119 can, in some examples, be a laser or a narrow non-laser light signal. As shown, the IR light signal 119 is configured to extend through a portion of the restroom 220 such that an individual entering or exiting the room intersects and interrupts the path of the IR light signal 119. When the path between the IR source 120 and the IR sensor 116 is interrupted, the IR sensor 116 does not receive the IR light signal 119. When the IR sensor 116 does not receive the IR light signal 119, the control unit 118 does not receive the sensed IR signal 122 from the IR sensor 116. Furthermore, the IR light signal 119 is directed such that an individual within the restroom 220 interrupts the IR light signal 119. The control unit 118 operates to ensure that the UV emitter 108 is turned off when an individual is within the toilet 220 (or other such room in which the UV lamp 104 is used).The control unit 118 determines whether the room is occupied or unoccupied by communicating with the IR sensor 116 (and optionally, the door sensor 242 shown in FIGS. 23 and 24). If occupied, the control unit 118 deactivates the UV emitter 108. If unoccupied, the control unit 118 can activate the UV emitter 108 to disinfect one or more components in the room.

[0031] FIG. 20 shows a perspective bottom view of a UV lamp 104 according to an example of the present disclosure.

[0032] 1 and 20 , the UV lamp 104, whether within a module 106 or not, includes a housing 240 having multiple UV light emitters 108. The IR sensor 116 is secured to the housing 240 and oriented to receive the IR light signal 119. The control unit 118 communicates with the IR sensor 116 and the UV light emitters 108. In at least one example, a door sensor 242 also communicates with the control unit 118, such as via one or more wired or wireless connections. In some examples, the door sensor 242 is a Hall-effect sensor. The door sensor 242 is configured to detect the opening and closing of a room door, such as the toilet 220 shown in FIGS. 18 and 19 . The control unit 118 selectively activates and deactivates the UV light emitters 108 based on the IR signal received from the IR sensor 116 (in some examples, the reception of the IR signal and the lack of reception of the IR signal) and the door signal received from the door sensor 242 (in some examples, a signal indicating that the door is open or closed). Optionally, the control unit 118 is not in communication with the door sensor.

[0033] 21 shows a perspective bottom view of a UV lamp 104 according to one example of the present disclosure. In this example, the IR sensor 116 is located remotely from the UV lamp 104 and communicates with a control unit 118 via one or more wired or wireless connections.

[0034] 22 shows a perspective bottom view of a UV lamp 104 according to one example of the present disclosure. As shown, the housing 240 can include an extension 245. The IR sensor 116 can be attached to the extension 245.

[0035] FIG. 23 shows a plan view of a toilet 220 according to an example of the present disclosure.

[0036] FIG. 24 shows a perspective interior view of the toilet 220 of FIG.

[0037] 1 and 19-24 , a door sensor 242, such as a Hall Effect sensor, is configured to cooperate with a magnet 260 disposed on the door 262 of the toilet 220 to determine when the door 262 is opened or closed. In some examples, when the magnet 260 is in contact with or close proximity (e.g., within 6 inches) to the door sensor 242, the door sensor 242 outputs a signal to the control unit 118 that the door 262 is closed. In at least one example, the door sensor 242 can be fixed to the housing 240 of the UV lamp 104. In at least one example, the control unit 118 deactivates the UV light emitter 108 of the UV lamp 104 in response to the IR sensor 116 not receiving the sensed IR signal 122 from the IR sensor 116. Conversely, the control unit 118 receives the sensed IR signal 122 from the IR sensor 116 and, in response to receiving a signal from the door sensor 242 indicating that the door 262 is closed, activates the UV light emitter 108 to disinfect one or more components within the restroom 220. In at least one example, in response to receiving a signal from the door sensor 242 indicating that the door 262 is open, the control unit 118 deactivates the UV light emitter 108, even when the control unit 118 receives the sensed IR signal 122 from the IR sensor 116.

[0038] FIG. 25 shows a perspective view of an IR sensor 116 according to an example of the present disclosure. In at least one example, the IR sensor 116 includes a socket 270 that movably holds a ball 272. The ball 272 holds a sensing element 274 configured to receive and detect IR light signals. The ball-and-socket configuration shown in FIG. 25 allows the sensing element 274 to be moved to a desired orientation and position to receive IR light signals. Optionally, the IR sensor 116 need not include a movable element, such as the ball 272 movably held within the socket 270.

[0039] 1 and 19-25, in at least one example, the control unit 118 activates the UV light emitter 108 in response to determining that the restroom 220 (or other such room) is vacant and unused. In some examples, the control unit 118 activates the UV light emitter 108 for a predetermined disinfection period (e.g., 5 seconds) in response to receiving a signal from the door sensor 242 that the door 262 is open and receiving the sensing IR light signal 122 for at least one second, and then receiving a signal from the door sensor 242 that the door 262 is closed and receiving the sensing IR light signal 122 for at least another second. If the control unit 118 detects that the door 262 has been opened during the disinfection period, the control unit 118 immediately deactivates the UV light emitter 108. Additionally, if the control unit 118 detects that the IR sensor 116 is not receiving the IR light signal 119 (e.g., by not receiving the sensed IR light signal 122 from the IR sensor), the control unit 118 deactivates the UV light emitter 108. Such an interruption in the IR light signal 119 triggers a reset event, in which the control unit 118 may re-activate the UV light emitter 108 after determining that the door 262 has been opened and received the sensed IR light signal 122 from the IR sensor 116, and then the door 262 has been closed and received another sensed IR light signal 122 from the IR sensor 116.

[0040] FIG. 26 shows a flowchart of a method for operating a UV lamp according to an example of the present disclosure.

[0041] 1 and 19-26 , at 300, the control unit 118 determines that the door 262 is open, such as via a signal received from the door sensor 242. At 302, the control unit 118 determines whether a sensed IR light signal 122 is received from the IR sensor 116. If not, the method proceeds to 304, where the control unit 118 deactivates the UV light emitter 108, and the method then returns to 300. However, if a sensed IR light signal 122 is received from the IR sensor 116 at 302, the control unit 118 determines whether the door 262 is closed, such as via a signal received from the door sensor 242. If the door is not closed, the method returns to 304. However, if the door 262 is closed, the control unit 118 determines whether a sensed IR light signal 122 is received at 308. If not, the method returns to 304. However, if the control unit 118 determines that the sensed IR light signal 122 was received at 308, the control unit 118 operates the UV lamp 104 at 310 to emit UV light from the UV emitter 108 for a predetermined disinfection time (e.g., 3-5 seconds). If the control unit 118 determines at 312 that the door 262 was opened during the predetermined disinfection time, the method returns to 304, where the control unit 118 immediately deactivates the UV emitter 108. However, if the door was not opened during the predetermined disinfection time at 312, the method proceeds from 312 to 314, where the control unit 118 operates the UV emitter 108 to continue emitting UV light until the predetermined time has elapsed, at which point the control unit 118 deactivates the UV emitter 108. The process then returns to 300.

[0042] FIG. 27 shows a perspective view of a module 106 according to one example of the present disclosure. The module 106 includes a sub-housing 400 that holds one or more UV light emitters 108. The sub-housing 400 is connected to a power source 402 via a cable 404. In contrast to the example shown in FIGS. 4 through 6 , the sub-housing 400 and the power source 402 may not be secured within a common bracket. Optionally, the sub-housing 400 and the power source 402 may, in some examples, be secured to a bracket, such as the bracket 150 shown and described with respect to FIGS. 4 through 6 . An EMI shield 114 (in some examples, a first EMI shield) is disposed around a portion of the sub-housing 400. In at least one example, the EMI shield 114 is disposed around all portions of the sub-housing 400 except for the opening 112. In at least one example, the EMI shield 114 is a metal foil (in some examples, a foil of stainless steel, aluminum, or the like) that extends around a portion of the sub-housing 400. The EMI shield 114 blocks, attenuates, or otherwise prevents EMI that may be generated by operation of the UV light emitter 108 from passing therebetween (and / or blocks EMI from passing into the sub-housing 400). The EMI shield 114 (in some examples, a second EMI shield) may also extend around a portion of the power supply 402 and / or the cable 404. In some examples, the EMI shield 114 may encase all portions of the power supply 402 and / or the cable 404. In at least one example, the EMI shield 114 covers the entire module 106, including the sub-housing 400, the power supply 402, and the cable 404, except for the opening 112. The EMI shield 114 blocks, attenuates, or otherwise prevents EMI from passing between the sub-housing 400 and the power supply 402. Additionally, by separating the sub-housing 400 from the power supply 402 (and connecting it via cable 404), the module 106 can be more easily integrated and used in certain limited areas where a common housing to hold both might be too large. The sub-housing 400 shown in FIG. 27 is low-profile and can fit into smaller spaces.The EMI shield 114 can be used with any of the examples described herein. Additionally, a module including a sub-housing 400 separated from a power supply 402 (as shown in FIG. 27) can be used with any of the examples described herein, with or without the EMI shield 114.

[0043] FIG. 28 illustrates a perspective bottom view of the sub-housing 400 of the module 106 of FIG. 27. In at least one example, an EMI grid 410 is disposed within the opening 112. The EMI grid 410 includes a plurality of longitudinal beams 412 intersecting a plurality of transverse beams 414 to define passages 416 therebetween. The beams 412 and 414 may have a thickness of 0.001 inches to 0.010 inches in some examples. As such, the EMI grid 410 may be a mesh screen or cage in some examples. The EMI grid 410 also prevents the passage of EMI to or from the module 106. In at least one example, the EMI grid 410 may be formed of stainless steel. Alternatively, the module 106 does not include an EMI grid 410.

[0044] FIG. 29 shows a side view of the module 106 of FIG. 27 secured to a wall 440, according to one example of the present disclosure. The sub-housing 400 can be attached to a first surface 442 (e.g., an outer surface or an inner surface) of the wall 440, and the power supply 402 can be disposed behind the wall 440. In some examples, the power supply 402 can be secured behind a second surface 444 (opposite the first surface) of the wall 440. An opening 446 formed through the wall 440 is configured to allow the cable 404 to pass through. In this manner, the wall 440 also isolates the sub-housing 400 from the power supply 402. The wall 440 can be part of a room. In some examples, the wall 440 can be a wall of a toilet, such as the toilet 220 shown in FIGS. 18, 19, 23, and 24.

[0045] 30 shows a perspective front view of a module 106 secured to a wall 440, according to one example of the present disclosure. The sub-housing 400 can be secured to the wall 440 such that a front surface 460, including the opening 112, is flush with a front surface 462 of the wall 440.

[0046] 31 shows a perspective front view of a module 106 secured to a wall 440, according to one example of the present disclosure. In this example, the sub-housing 400 can be secured within a perimeter collar 470 that attaches the sub-housing 400 to the wall 440.

[0047] 32 shows a perspective front view of a module 106 secured to a wall 440, according to one example of the present disclosure. This example is similar to that shown in FIG. 31, except that the opening 112 may be angled (i.e., not parallel) relative to the front surface 462 of the wall 440.

[0048] FIG. 33 shows a perspective front view of a module 106 secured to a wall 440, according to one example of the present disclosure. In this example, a shielding shroud 500, such as a metal cylinder, is secured to and / or behind the wall 440. The power supply 402 (shown in FIG. 29 in some examples) is held within the shielding shroud 500. In this example, the shielding shroud 500 provides EMI shielding for the power supply 402. Additional EMI shielding, such as in the form of a metal foil, may or may not extend around the power supply 402 within the shielding shroud 500. In at least one example, the shielding shroud 500 is configured to fit into and be held within an opening formed in the wall 440. Thus, the shielding shroud 500 can be easily installed in the wall 440.

[0049] FIG. 34 illustrates a perspective rear view of the sub-housing 400 of the module 106 according to one example of the present disclosure. As shown, the sub-housing 400 may include a cooling fan 510 and multiple ventilation openings 512. The cooling fan 510 operates to cool the UV light emitter 108 during operation, and the ventilation openings 512 draw in cooling air and / or allow air to pass through the sub-housing 400. The cooling fan 510 and ventilation openings 512 may be used in any of the examples described herein. In examples where an EMI shield covers a portion of the sub-housing 400, the EMI shield does not cover the cooling fan 510 and ventilation openings 512. The ventilation openings 512 may be sized and shaped depending on EMI wavelength requirements. In some examples, at least one example, the ventilation openings 512 may be between 0.5 inches and 1.0 inches.
