Description

Technical Field

[0001] Examples of this disclosure generally relate to disinfection systems that can be used to disinfect structures and areas within a vehicle, and more specifically to systems and methods for disinfecting components using ultraviolet (UV) light. Background Technology

[0002] Vehicles such as commercial aircraft are used to transport passengers between various locations. In at least one example, systems are currently being developed that use ultraviolet (UV) light to sterilize or otherwise disinfect surfaces inside the aircraft.

[0003] UV light disinfection systems typically include a UV lamp, which comprises multiple UV light emitters. A UV lamp is formed by integrating the various UV light emitters into a single housing and coupling the UV light emitters to individual power supplies.

[0004] It is understandable that a UV lamp can have many UV light emitters. Manufacturing such a UV lamp is a time-consuming and labor-intensive process. Furthermore, if one or more UV light emitters fail, replacing them can also result in a time-consuming and labor-intensive process.

[0005] Furthermore, UV light sterilization occurs in various environments when the area is unoccupied. In at least one example, lavatories inside an aircraft can be sterilized using UV light. However, this sterilization typically does not occur when an individual is inside the lavatory.

[0006] In addition, the UV light emitter generates electromagnetic interference (EMI) during operation, which can affect the operation of the UV lamp and / or other devices.

[0007] Furthermore, only certain areas within the interior compartments may have permanently installed UV sterilization systems. In at least one example, the lavatory may include a UV sterilization system. However, various other areas within the interior compartments may not include a UV sterilization system. Summary of the Invention

[0008] There is a need for UV sterilization systems that can be easily installed and fixed in areas such as the interior cabins of aircraft.

[0009] In view of this need, certain examples of this disclosure provide a system for sterilizing one or more components. The system includes one or more ultraviolet (UV) lamps. The one or more UV lamps include one or more UV light emitters and a mounting interface, the one or more UV light emitters being configured to emit UV light, and the mounting interface being removably secured to a fixed mounting component.

[0010] In at least one example, the control unit is configured to control the operation of the one or more UV light emitters. In at least one example, the one or more UV lamps may include the control unit.

[0011] In at least one example, one or more UV lamps include one or more sensors that communicate with a control unit. The one or more sensors are configured to detect the presence or movement of the one or more UV lamps. Furthermore, the control unit may be configured to control one or more of the following for sterilization of the one or more UV lamps: power level, irradiance level, intensity level, or timing period, based on presence signals received from the one or more sensors. As an example, the control unit is configured to predict future operation of one or more UV light emitters based on presence data stored in a memory.

[0012] In at least one example, one or more UV lamps include a position detector that communicates with a control unit. The position detector is configured to detect the position of one or more UV lamps within an area. As yet another example, the control unit is configured to operate one or more UV light emitters based on the position of the UV lamps within the area detected by the position detector.

[0013] In at least one example, one or more UV light emitters include a first UV light emitter and a second UV light emitter, the first UV light emitter being configured to emit UV light of a first wavelength and the second UV light emitter being configured to emit UV light of a second wavelength different from the first wavelength. In at least one example, a control unit is configured to control the one or more UV light emitters to emit UV light of different wavelengths based on sensed or predicted behavior near the UV lamp.

[0014] As an example, one or more UV lamps include a power source and one or more batteries.

[0015] In at least one example, the control unit is configured to operate one or more UV light emitters based on the sensed output voltage.

[0016] In at least one example, one or more UV lamps comprise multiple UV lamps. The multiple UV lamps are configured to communicate with each other.

[0017] In at least one example, the external monitoring system communicates with one or more UV lamps. The external monitoring system is configured to control one or more UV lamps.

[0018] Certain examples of this disclosure provide a method for sterilizing one or more components. The method includes removably attaching one or more ultraviolet (UV) lamps to a mounting component, wherein the one or more UV lamps include one or more UV light emitters configured to emit UV light toward the mounting component. In at least one example, the method further includes controlling the operation of the one or more UV light emitters by a control unit.

[0019] Certain examples of this disclosure provide a system for sterilizing one or more components. The system includes a first subset of one or more ultraviolet (UV) lamps, a second subset of one or more UV lamps, and a control unit. The first subset is fixed within a first region, and the second subset is fixed within a second region spaced apart from the first region. Each UV lamp in the first and second subsets includes one or more UV light emitters and a mounting interface configured to emit UV light. The mounting interface is removably fixed to a corresponding mounting bracket. The control unit is configured to control the operation of one or more UV light emitters in each of the UV lamps in the first and second subsets. Attached Figure Description

[0065] The foregoing summary of certain examples and the following detailed description will be better understood when read in conjunction with the accompanying drawings. As used herein, elements or steps stated in the singular or beginning with the words “a” or “an” should be understood to not necessarily exclude multiple elements or steps. Furthermore, references to “an example” should not be construed as excluding the existence of other examples that also include the stated features. Moreover, unless expressly stated to the contrary, examples that “comprise” or “have” one or more elements having a particular condition may include additional elements that do not have that condition.

[0066] Certain examples of this disclosure provide a system for sterilizing one or more components (in at least one example, disinfection, purification, cleaning, etc.). The system includes multiple modules coupled together to form a UV lamp. Each of the multiple modules includes one or more UV light emitters configured to emit UV light onto the component to sterilize it. In at least one example, each of the modules also includes a power supply coupled to the UV light emitter. The module may also include a bandpass filter configured to filter the UV light generated from the UV light emitter to a desired wavelength, such as in the far UV spectrum, UVC spectrum, etc. In at least one example, different modules may emit UV light of different wavelengths. In at least one example, a first module may emit UV light in the far UV spectrum, while a second module coupled to the first module may emit UV light in the UVC spectrum. Optionally, the system may not include multiple modules.

[0067] Multiple modules can be coupled together as needed (in at least one example, stacked, grouped, or otherwise connected) for UV coverage of a larger area. Such a configuration can be determined based on the dimensions of the surface to be disinfected. Modules can be coupled together via adhesives, one or more mechanical connectors, or fasteners.

[0068] A UV lamp, composed of multiple modules, can be customized to fit into a desired area. Therefore, the UV lamp can be compact and configured to fit into small, confined spaces.

[0069] In at least one example, the UV lamp is configured as part of a cane assembly held by an operator. In at least one other example, the UV lamp is a fixed device within a space (such as a washroom). The UV lamp can be fixed in a suitable location within the space. Optionally, the UV lamp can be configured to move between a retracted position and an extended position within the space. Alternatively, the UV lamp can be removably fixed to a fixed mount.

[0070] In at least one example, the system includes an infrared (IR) sensor that communicates with a control unit. The IR sensor is configured to detect IR light, such as an IR beam emitted from an IR source, which can be reflected back to the IR sensor. In 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 at least one example, the control unit prevents the activation and / or deactivation of the UV light emitters in response to the IR sensor not detecting IR light.

[0071] In at least one example, the IR source and / or IR reflector may be positioned, such as near the bathroom door (in at least one example, at or within the foot of the door, or smaller). The IR sensor is configured to monitor the IR beam and detect changes when an occupant crosses a threshold. Additionally, the system may include a door sensor (e.g., a door Hall effect sensor) mounted on and / or near the door to detect when the door is open 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 one or more IR signals received from the IR sensor and / or the door sensor.

[0072] In at least one example, the control unit is configured to deactivate the UV light emitter when an area (such as 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.

[0073] Certain examples of this disclosure provide sterilization systems and methods including ultraviolet (UV) lamps (such as excimer lamps having one or more UV light emitters, such as light-emitting diodes, light bulbs, etc.), said UV lamps emitting UV light in the far-UV spectrum (such as a wavelength of 222 nm), said UV light neutralizing (such as killing) microorganisms (in at least one example, viruses and bacteria) without posing a risk to humans. Optionally, said UV lamps emitting UV light in the UVC spectrum (such as a wavelength of 254 nm). The UV lamps can be used in interior compartments for purifying and killing pathogens. The UV lamps can be used in portable or stationary disinfection systems. In at least one example, operating the UV lamp to emit disinfecting UV light having wavelengths within the far-UV or UVC spectrum can be used with portable or stationary systems.

[0074] Some examples of this disclosure provide a standalone, universal modular UV lamp, such as having one or more modules that can be fixed and installed at various locations within an area, such as the interior of an aircraft cabin. The UV lamp can be selectively fixed and removed from its installation location. In at least one example, the UV lamp communicates with a monitoring subsystem configured to detect the location of the UV lamp within the area. The monitoring subsystem can also be configured to predict activity related to the location of the UV lamp and control the UV lamp accordingly.

[0075] Some examples of this disclosure provide a portable UV lamp. In at least one example, the UV lamp includes one or more modules. In at least one example, the UV lamp includes one or more light emitters, a controller, a housing, a memory, a power supply, one or more sensors, one or more indicators, a communication device, a position detection device, and a mounting interface. The UV lamp is configured to be installed or modified in an area to be sterilized.

[0076] In at least one example, the UV lamp is configured to modulate the level of UV irradiation based on the occupancy of a region. The UV lamp is configured to determine its location within the region and communicate with other UV lamps in the same region or with other systems outside the region to manage functions such as power levels, system health, system performance, and system problems.

[0077] Figure 1 The illustration shows a schematic block diagram of a system 100 for sterilizing component 102 according to an example of this disclosure. Component 102 can be any structure to be sterilized with UV light. In at least one example, component 102 can be a structure within a vehicle, a fixed building, or the like. As an example, component 102 can be a passenger seat within a vehicle, a part of a washroom (such as a toilet, sink, door handle, etc.), a counter or other such surface in a stove or kitchen, etc.

[0078] System 100 includes a UV lamp 104, which includes a plurality of modules 106 coupled together. In at least one example, the UV lamp 104 includes a first module 106 coupled to a second module 106. Optionally, the UV lamp 104 may include more than two modules 106.

[0079] Each module 106 includes one or more UV light emitters 108 configured to emit UV light through aperture 112. The UV light emitters 108 can emit UV light within the far UV spectrum (e.g., between 200 nanometers (nm) and 230 nm). In at least one example, the UV light emitter can emit 222 nm UV light. As another example, the UV light emitter 108 can emit UV light within the UVC spectrum (e.g., between 230 nm and 280 nm). In at least one example, the UV light emitter can emit 254 nm UV light. In at least one example, the UV light emitters 108 of module 106 emit UV light of the same wavelength. In at least one other example, the UV light emitters 108 of module 106 emit UV light of different wavelengths. In at least one example, the UV light emitter 108 of the first module 106 emits UV light within the far UV spectrum, and the UV light emitter 108 of the second module 106 emits UV light within the UVC spectrum, or vice versa.

[0080] Modules 106 are coupled together to form the light-emitting portion of the UV lamp 104. Modules 106 can be removably coupled together. Therefore, the UV lamp 104 provides a modular component that can be customized to the desired size, shape, and illumination capability. Furthermore, if module 106 requires repair, it can be removed from the UV lamp 104 and replaced within another module 106. Thus, modules 106 allow for efficient production and maintenance of the UV lamp 104.

[0081] In at least one example, multiple portions of module 106 are covered with one or more electromagnetic interference (EMI) shields 114. In at least one example, one or more UV light emitters 108 are surrounded by EMI shields 114 on one or more surfaces, wherein the apertures 112 are not covered by the EMI shields 114. In at least one example, the EMI shields 114 are metallic coverings, such as foils formed of aluminum, steel, etc., covering the housing of module 106, wherein the apertures 112 remain uncovered. Optionally, module 106 does not include EMI shields 114.

[0082] UV lamp 104 can be part of a cane assembly configured to be held by an individual. The cane assembly can be coupled to a backpack assembly, shell assembly, trolley, etc. As another example, the cane assembly can be a separate component not coupled to a backpack assembly, shell assembly, trolley, etc.

[0083] As another example, the UV lamp 104 can be a fixed device within an area. In at least one example, the UV lamp 104 can be fixed in a washroom, kitchen, stove room, or various other areas. The UV lamp 104 can be fixed in a suitable location within the area. Optionally, the UV lamp 104 can be movable within the area between a retracted position and an extended position. In at least one other example, the UV lamp 104 can be removably fixed to various structures, such as fixed mounts located within an area (such as inside a vehicle).

[0084] In at least one example, system 100 also includes an infrared (IR) sensor 116, such as communicating with control unit 118 via one or more wired or wireless connections. Control unit 118 also communicates with UV light emitter 108 of module 106, such as via one or more wired or wireless connections. In at least one example, UV lamp 104 includes IR sensor 116 and / or control unit 118. Optionally, IR sensor 116 and / or control unit 118 may be positioned remotely from UV lamp 104.

[0085] In operation, control unit 118 selectively activates and deactivates UV light emitters 108 based on IR signals emitted by and received from IR sensor 116. In at least one example, IR sensor 116 is configured to receive IR light signals 119 emitted by IR source 120 directly from IR source 120 or indirectly from a reflector that receives and reflects IR light signals 119 from IR source 120. When IR sensor 116 receives IR light signals 119, IR sensor 116 outputs a sensed IR signal 122 to control unit 118. Based on the received sensed IR signal 122, control unit 118 activates one or more UV light emitters 108 to emit UV light. However, if IR sensor 116 does not receive IR light signals 119 (e.g., if IR light signals 119 are blocked by an individual), IR sensor does not output the sensed IR signal 122 to control unit 118. In response to the absence of a sensed IR signal 122, the control unit 118 disables the UV light emitters 108, preventing them from emitting UV light.

[0086] In at least one example, the activation switch 124 communicates with the control unit 118 via one or more wired or wireless connections. The activation switch 124 may be fixed to the UV lamp 104. That is, the UV lamp 104 may include the activation switch 124. Optionally, the activation switch 124 may be positioned 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 explained above (i.e., the control unit 118 selectively activates and deactivates the UV light emitter based on signals received from the IR sensor 116). When the activation switch 124 is disengaged, causing the UV light emitter 108 to stop emitting UV light, the control unit 118 maintains the UV light emitter 108 in a deactivated state, even if a sensed IR signal 122 is received from the IR sensor 116. Optionally, the system 100 may not include an activation switch.

[0087] In at least one example, system 100 includes a UV lamp 104 having a UV light emitter 108 (whether or not within module 106). In at least one example, the UV lamp 104 may be a single, non-modular component communicating with a control unit 118, which selectively activates and deactivates the UV light emitter 108 as described herein. In at least one other example, system 100 does not include an IR sensor 116 or an IR source 120.

These are merely exemplary and are therefore not intended to limit the definition and / or meaning of these terms in any way. In at least one example, control unit 118 may be or include one or more processors configured to control operations as described herein.

[0089] Control unit 118 is configured to execute a set of instructions stored in one or more data storage units or elements (such as one or more memories) to process data. In at least one example, control unit 118 may include or be coupled to one or more memories. Data storage units may also store data or other information as desired or required. Data storage units may take the form of information sources within a processor or physical memory elements.

[0090] The instruction set may include various commands that instruct the control unit 118, acting as a processor, to perform specific operations (such as methods and procedures exemplified by various examples of the subject matter described herein). The instruction set may be in the form of a software program. Software may take various forms, such as system software or application software. Furthermore, software may be in the form of a collection of individual programs, a subset of programs within a larger program, or a part of a program. Software may also include modular programming in the form of object-oriented programming. The processor's processing of input data may be in response to user commands, the results of previous processing, or a request made by another processor.

[0091] The schematic diagrams in this document may illustrate one or more control or processing units, such as control unit 118. It should be understood that a processing or control unit may represent a circuit, circuit system, or portion thereof that can be implemented to have associated instructions for performing the operations described herein (e.g., software stored on a tangible and non-transitory computer-readable storage medium, such as a computer hard disk drive, ROM, RAM, etc.). The hardware may include state machine circuits hardwired to perform the functions described herein. Optionally, the hardware may include electronic circuitry comprising and / or connected to one or more logic-based devices, such as microprocessors, processors, controllers, etc. Optionally, control unit 118 may represent processing circuitry, such as one or more of field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), microprocessors, etc. The circuits in the various examples may be configured to execute one or more algorithms to perform the functions described herein.

[0092] As used herein, the terms “software” and “firmware” are interchangeable and include any computer program stored in a data storage unit (in at least one example, one or more memories) for execution by a computer, including RAM memory, ROM memory, EPROM memory, EEPROM memory, and non-volatile RAM (NVRAM) memory. The data storage unit types described above are merely exemplary and are therefore not limited to the types of memory that can be used to store computer programs.

[0093] Figure 2The illustration shows a perspective bottom view of module 106 according to an example of this disclosure. Module 106 includes a housing 130 holding a plurality of UV light emitters 108 configured to emit UV light through apertures 112. As shown, 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 contained within a first sub-housing 132, and the second plurality of UV light emitters 108b are contained within a second sub-housing 134, different from the first sub-housing 132. Each of the first sub-housing 132 and the second sub-housing 134 may contain more or fewer UV light emitters 108 than shown. Optionally, module 106 may include a holding Figure 2 A single sub-housing for all UV light emitters 108 shown. In at least one example, module 106 may include a single UV light emitter 108 instead of multiple UV light emitters 108.

[0094] Figure 3 The illustration shows a perspective bottom view of a first module 106a coupled to a second module 106b according to an example of this disclosure. A first end 140 of the first module 106a is coupled to a corresponding second end 142 of the second module 106b. Optionally, the first module 106a and the second module 106b may be coupled together side-to-side. Another module ( Figure 3 (Not shown in the image) can be coupled to the second terminal 144 of the first module 106a. Additionally, another module ( Figure 3 (Not shown in the image) can be coupled to the first end 146 of the second module 106b.

[0095] Modules 106a and 106b, along with additional modules, can be stacked end-to-end and / or side-to-side as needed to provide various lighting patterns. The first module 106a and the second module 106b can be removably coupled together, such as via one or more fasteners, adhesives, dovetail joints, lap joints, plugs, and socket connections. Therefore, 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 in cases where one of the first module 106a or the second module 106b requires repair or replacement.

[0096] Figure 4 The illustration shows a perspective end view of module 106 according to an example of this disclosure. Figure 5 The diagram shows Figure 4 The perspective top view of module 106. Figure 6 The diagram shows Figure 4 The perspective bottom view of module 106. (Reference) Figure 4-6 For clarity, certain portions of the outer wall of module 106 are not shown in order to show the internal components.

[0097] In at least one example, housing 130 includes a support 150 having a platform 152 extending between opposing sidewalls 154 and 156. Platform 152 includes an upper surface 158 opposite to lower surface 160. Partition wall 161 extends upward from upper surface 156. First power chamber 162 is defined between upper surface 158, inner surface 163 of sidewall 154, and first side surface 165 of partition wall 161. Second power chamber 164 is defined between upper surface 158, inner surface 167 of sidewall 156, and second side surface 169 of partition wall 161 (opposite to first side surface 165). Transmitter chamber 170 is defined between lower surface 158, inner surface 163 of sidewall 154, and inner surface 167 of sidewall 156.

[0098] The first power supply 172 is fixed inside the first power chamber 162. The second power supply 174 is fixed inside the second power chamber 164. (Reference) Figure 1-6 The first power supply 172 and the second power supply 174 may be batteries and / or power interfaces, connections, etc., configured to provide power to the UV light emitter 108.

[0099] In at least one example, the frame 176 is secured within the emitter chamber 170, such as by 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 of 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 wires passing through slots, channels, or other such openings formed in the platform 152.

[0100] Platform 152 separates and isolates frame 176 (including UV light emitter 108) from first power supply 172 and second power supply 174. Furthermore, partition wall 161 separates and isolates first power supply 172 from second power supply 174. In at least one example, first power supply 172 and second power supply 174 can be high-voltage power supplies (e.g., 2kV), and therefore the separation and isolation between them and relative to frame 176 ensures reliable and efficient operation.

[0101] As shown, a first power supply 172 and a second power supply 174 are stacked on top of a frame 176, which holds the first sub-housing 132 and the second sub-housing 134. Optionally, a single power supply can be used to power the UV light emitters 108 of the first sub-housing 132 and the second sub-housing 134. In at least one example, the support 150 may not include the partition wall 161. In at least one other example, the power supply(s) may be located away from the module 106.

[0102] Figure 7The illustration shows a perspective bottom view of a bracket 150 according to an example of this disclosure. Figure 8 The diagram shows Figure 7 A perspective top view of the bracket at 150 degrees. (Reference) Figure 7 and Figure 8 The support 150 may include one or more channels 180 (e.g., slots) formed through the platform 152. (See reference...) Figure 1-8 In at least one example, channel 180 allows wiring to travel between the UV light emitter 108 and the power supplies 172 and / or 174. Optionally, the bracket 150 may not include channel 180. Alternatively, in at least one example, the wiring may travel around the end edge of the platform 152.

[0103] As shown in the figure, sidewalls 154 and 156 may each include inwardly inclined segments 155 and 157 that define the first power chamber 162 and the second power chamber 164, respectively. The free ends of the inwardly inclined segments are angled toward the partition wall 161. The inwardly inclined segments 155 and 157 provide a more compact support 150 that occupies less space. Optionally, sidewalls 154 and 156 may also or alternatively include inwardly inclined segments. Alternatively, support 150 may not include inwardly inclined segments.

[0104] Figure 9 A bottom view of multiple modules 106a, 106b, and 106c coupled together according to an example of this disclosure is illustrated. A first end 140a of module 106a is fixed to a second end 142b of module 106b. A first end 140b of module 106b is fixed to a second end 142c of module 106c. As shown, modules 106a, 106b, and 106c are linearly aligned in the X direction in an end-to-end configuration. Optionally, one or more of modules 106a, 106b, and 106c may be aligned in a side-to-side configuration in the Y direction. Wiring 190 travels to each of modules 106a, 106b, and 106c.

[0105] Figure 10 A bottom view of a plurality of modules 106a, 106b, 106c, and 106d coupled together according to an example of the present disclosure is illustrated. As shown, module 106d may be fixed to module 106b in a side-to-side manner. Alternatively, module 106d may be coupled to module 106a or 106c. In at least one other example, an additional module (not shown) may be coupled to each of modules 106a, 106b, or 106c in a side-to-side configuration.

[0106] Figure 11The illustration shows a bottom view of a first module 106a coupled to a second module 106b according to an example of this disclosure. The first module 106a is coupled to the second module 106b via an adhesive at an adhesive interface 192 therebetween.

[0107] Figure 12 The illustration shows a bottom view of a first module 106a coupled to a second module 106b according to an example of this disclosure. The first module 106a is coupled to the second module 106b via a connection joint 194 (e.g., a dovetail joint).

[0108] Figure 13 The illustration shows a bottom view of a first module 106a coupled to a second module 106b according to an example of this disclosure. The first module 106a is coupled to the second module 106b via one or more connection joints 196 (such as lap joints at the ends and / or sides of the connection). Fasteners (such as screws or bolts) and / or adhesives may be used to secure the connection joints 196 to the first module 106a and the second module 106b.

[0109] Figure 14 The illustration shows a bottom view of a UV lamp 104 having multiple modules 106 according to an example of the present disclosure. The UV lamp 104 may include a battery 200, such as a 24V battery, that supplies power to the power source of the modules 106. In at least one example, the battery 200 is configured to cooperate with a power line 202 to be recharged.

[0110] Figure 15 The illustration shows a bottom view of a UV lamp 104 having multiple modules 106 according to an example of this disclosure. In this example, the UV lamp 104 may not include a battery. Alternatively, the UV lamp receives power from a power line 202.

[0111] Figure 16 The illustration shows a perspective side view of a cane assembly 210 including a UV lamp 104 according to an example of the present disclosure. Figure 17 The diagram shows Figure 16 A bottom view of the cane components. (Reference) Figure 16 and Figure 17 The cane assembly 210 includes a sterilization head 212 coupled to the handle 213. The sterilization head 212 includes a shield 214 that holds the UV lamp 104. The battery 200 can be held within the shield 214.

[0112] In at least one example, the sterilizing head 212 is configured to move relative to the handle 213. In at least one example, the sterilizing head 212 may extend and / or rotate relative to the handle 213. In at least one other example, the sterilizing head 212 is fixed relative to the handle 213. The cane assembly 210 may include a UV lamp 104 having a plurality of modules 106, as described above. Figure 1-15Any of the descriptions in [the text].

[0113] Figure 18 The illustration shows a perspective interior view of a lavatory 220 according to an example of this disclosure. The lavatory 220 may be located within the interior cabin of a vehicle, such as a commercial aircraft. The lavatory 220 includes a toilet 222 and a countertop 224 having a sink 226 and a faucet 228. One or more UV lamps 104 are disposed within the lavatory 220. The UV lamps 104 are as described above... Figure 1-15 Configure it as described in any of the descriptions.

[0114] UV lamp 104 is configured to emit UV light to sterilize one or more components (such as toilet 222, countertop 224, sink 226, faucet 228, floor 230, one or more walls 232, etc.) within washroom 220. In at least one example, UV lamp 104 may be fixed in place. In at least one other example, UV lamp 104 may be configured to be movable. In at least one example, UV lamp 104 may be movable between a retracted position and an extended position.

[0115] Figure 19 The illustration shows a perspective interior view of a washroom 220 according to an example of this disclosure. (Reference) Figure 1 and Figure 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 the area in which an individual occupies the washroom 220.

[0116] The IR sensor 116 can be aligned with the IR source 120 to receive the IR light signal 119 directly from the IR source 120. Alternatively, the IR source 120 can be configured to emit the IR light signal 119 at a reflector (such as a plane mirror) that reflects the IR light signal 119 back to the IR source 120.

[0117] The IR sensor 116 can be directly mounted to the UV lamp 104, such as by mounting it on a housing. In at least one example, the IR sensor 116 can 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 located away from the UV lamp 104.

[0118] As shown, the IR sensor 116 can be fixed to the end or corner of the UV lamp 104. The IR sensor 116 is configured to receive the IR light signal 119 directly from the IR source 120 or indirectly from the IR source 120 (e.g., by reflection from one or more reflectors 121). In at least one example, the IR light signal 119 can be a laser or a narrow non-laser light signal.

[0119] As shown in the figure, the IR light signal 119 is configured to extend through a portion of the washroom 220, causing a person entering or leaving the room to cross the path of the IR light signal 119 and interrupt it. 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 washroom 220 will interrupt it.

[0120] The control unit 118 operates to ensure that the UV light emitter 108 is deactivated when an individual is in the washroom 220 (or another such room in which the UV lamp 104 is used). This is achieved by communicating with the IR sensor 116 (and optionally, as...). Figure 23 and Figure 24 The control unit 118 communicates with the door sensor 242 shown to determine whether the room is occupied or unoccupied. If occupied, the control unit 118 deactivates the UV light emitter 108. If unoccupied, the control unit 118 can activate the UV light emitter 108 to sterilize one or more components in the room.

[0121] Figure 20 The illustration shows a perspective bottom view of a UV lamp 104 according to an example of this disclosure. (Reference) Figure 1 and Figure 2 The UV lamp 104 includes a housing 240 having a plurality of UV light emitters 108 (whether or not within module 106). An IR sensor 116 is attached to the housing 240 and is oriented in the direction of receiving IR light signals 119.

[0122] Control unit 118 communicates with IR sensor 116 and UV light emitter 108. In at least one example, door sensor 242 also communicates with control unit 118 via one or more wired or wireless connections. In at least one example, door sensor 242 is a Hall effect sensor. Door sensor 242 is configured to detect rooms (such as...) Figure 18 and Figure 19 The opening and closing of the door of the washroom 220 shown. Control unit 118 selectively activates and deactivates UV light emitter 108 based on IR signals received from IR sensor 116 (in at least one example, receiving one or more of these IR signals and not receiving one or more of these IR signals) and door signals received from door sensor 242 (in at least one example, a signal indicating that the door is open or closed). Optionally, control unit 118 does not communicate with the door sensor.

[0123] Figure 21 The illustration shows a perspective bottom view of a UV lamp 104 according to an example of this disclosure. In this example, an IR sensor 116 is positioned away from the UV lamp 104 and communicates with a control unit 118 via one or more wired or wireless connections.

[0124] Figure 22 The illustration shows a perspective bottom view of a UV lamp 104 according to an example of the present disclosure. As shown, the housing 240 may include an extension 245. An IR sensor 116 may be mounted on the extension 245.

[0125] Figure 23 The illustration shows a top plan view of a washroom 220 according to an example of the present disclosure. Figure 24 The diagram shows Figure 23 A perspective interior view of washroom 220. (Reference) Figure 1 and Figure 19-24 A door sensor 242 (e.g., a Hall effect sensor) is configured to cooperate with a magnet 260 located on a door 262 of the washroom 220 to determine when the door 262 is open or closed. In at least one example, when the magnet 260 touches or comes into close proximity to the door sensor 242 (e.g., within 6 inches or less), 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 may be attached to the housing 240 of the UV lamp 104.

[0126] In at least one example, control unit 118 deactivates UV light emitter 108 of UV lamp 104 in response to IR sensor 116 not receiving a sensed IR signal 122 from IR sensor 116. Conversely, control unit 118 activates UV light emitter 108 to sterilize one or more components within washroom 220 in response to receiving a sensed IR signal 122 from IR sensor 116 and a signal indicating door 262 is closed from door sensor 242. In at least one example, control unit 118 deactivates UV light emitter 108 even if control unit 118 receives a sensed IR signal 122 from IR sensor 116 in response to receiving a signal indicating door 262 is open from door sensor 242.

[0127] Figure 25 The illustration 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. Figure 25The ball-and-socket configuration shown allows the sensing element 274 to be moved to the desired orientation and alignment in order to receive IR light signals. Alternatively, the IR sensor 116 may not include movable elements, such as a ball 272 movably held within the socket 270.

[0128] refer to Figure 1 and Figure 19-25 In at least one example, control unit 118 activates UV light emitter 108 in response to determining that washroom 220 (or other such room) is vacated and unoccupied. In at least one example, control unit 118 activates UV light emitter 108 for a predetermined disinfection period (e.g., 5 seconds) in response to receiving a signal from door sensor 242 that door 262 is open and a sensed IR light signal 122 for at least one second, followed by receiving a signal from door sensor 242 that door 262 is closed and a sensed IR light signal 122 for at least another second. If control unit 118 detects that door 262 is open during the sterilization period, control unit 118 immediately deactivates UV light emitter 108.

[0129] Furthermore, 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. This interruption of the IR light signal 119 triggers a reset event, whereby the control unit 118 can then reactivate the UV light emitter 108 after determining that the door 262 has been opened, the sensed IR light signal 122 has been received from the IR sensor 116, the door 262 has subsequently closed, and the sensed IR light signal 122 has been further received from the IR sensor 116.

[0130] Figure 26 A flowchart illustrating a method for operating a UV lamp according to an example of this disclosure is shown. (Reference) Figure 1 and Figure 19-26 At 300, control unit 118 determines whether door 262 is open, for example, via a signal received from door sensor 242. At 302, control unit 118 determines whether sensed IR light signal 122 is received from IR sensor 116. If not, the method proceeds to 304, where control unit 118 deactivates UV light emitter 108, and then the method returns to 300.

[0131] However, if a sensed IR light signal 122 is received from IR sensor 116 at 302, control unit 118 determines whether door 262 is closed, for example, via a signal received from door sensor 242. If the door is not closed, the method returns to 304.

[0132] However, if door 262 is closed, control unit 118 determines at 308 whether the sensed IR light signal 122 has been received. If not, the method returns to 304.

[0133] However, if the control unit 118 determines at 308 that it has received the sensed IR light signal 122, then at 310 the control unit 118 operates the UV lamp 104 to emit UV light from the UV light emitter 108 for a predetermined disinfection time (such as 3-5 seconds). If at 312 the control unit 118 determines that the door 262 has been opened during the predetermined disinfection time, the method returns to 304, where the control unit 118 immediately deactivates the UV light emitter 304.

[0134] However, if at point 312 the door is not opened during the predetermined disinfection time, the process proceeds from 312 to 314, where the control unit 118 operates the UV light emitter 108 to continue emitting UV light until the predetermined time expires, at which point the UV light emitter 108 is deactivated. The process then returns to 300.

[0135] Figure 27 The illustration shows a perspective view of module 106 according to an example of this disclosure. Module 106 includes a sub-housing 400 that holds one or more UV light emitters 108. The sub-housing 400 is coupled to a power supply 402 via a cable 404. Figure 4-6 Compared to the example shown, the sub-housing 400 and power supply 402 may not be fixed within a common bracket. Alternatively, in at least one example, the sub-housing 400 and power supply 402 may be fixed to a bracket, such as regarding... Figure 4-6 The bracket 150 is shown and described.

[0136] An EMI shield 114 (in at least one example, 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 hole 112. As an example, the EMI shield 114 is a metal foil (in at least one example, stainless steel, aluminum, or a similar foil) extending around multiple portions of the sub-housing 400. The EMI shield 114 blocks, attenuates, or otherwise impedes the passage of EMI that may be generated by the operation of the UV light emitter 108 (and / or blocks EMI from entering the sub-housing 400).

[0137] EMI shielding 114 (in at least one example, a second EMI shielding) may also extend around multiple portions of power supply 402 and / or cable 404. In at least one example, EMI shielding 114 may wrap around all portions of power supply 402 and / or cable 404. In at least one example, EMI shielding 114 covers the entire module 106, including sub-housing 400, power supply 402, and cable 404, except for the hole 112. EMI shielding 114 blocks, attenuates, or otherwise impedes the transmission of EMI between sub-housing 400 and power supply 402.

[0138] Furthermore, by separating the sub-housing 400 from the power supply 402 (and connecting them via cable 404), module 106 can be more easily integrated and used in certain confined areas where a shared housing for both might be too large. Figure 27 The sub-shell 400 shown has a low profile and can fit into a smaller space.

[0139] EMI shielding 114 can be used with any of the examples described herein. Additionally, modules including a sub-housing 400 separate from the power supply 402 (such as...) Figure 27 (As shown) can be used with any of the examples described herein (whether with or without EMI shielding 114).

[0140] Figure 28 The diagram shows Figure 27 A perspective bottom view of the sub-housing 400 of module 106. In at least one example, an EMI grid 410 is disposed within an aperture 112. The EMI grid 410 includes a plurality of longitudinal beams 412 intersecting with a plurality of transverse beams 414, thereby defining a channel 416 therebetween. In at least one example, the beams 412 and 414 may have a thickness between 0.001” and 0.010”. In this way, in at least one example, the EMI grid 410 may be a mesh screen or a cage. The EMI grid 410 also prevents EMI from entering or leaving module 106. In at least one example, the EMI grid 410 may be formed of stainless steel. Alternatively, module 106 may not include an EMI grid 410.

[0141] Figure 29 The illustration shows an example of fixing to wall 440 according to the present disclosure. Figure 27A side view of module 106. The sub-housing 400 can be mounted on a first surface 442 (such as an outer or inner surface) of the wall 440, and the power supply 402 can be disposed behind the wall 440. In at least one example, the power supply 402 can be fixed behind a second surface 444 of the wall 440 (opposite to the first surface). An opening 446 formed through the wall 440 is configured to allow a cable 404 to pass through it. In this way, the wall 440 also isolates the sub-housing 400 from the power supply 402.

[0142] Wall 440 can be part of a room. In at least one example, wall 440 can be a washroom (such as...). Figure 18 , Figure 19 , Figure 23 and Figure 24 The wall of the washroom 220 shown.

[0143] Figure 30 The illustration shows a perspective front view of a module 106 fixed to a wall 440 according to an example of the present disclosure. A sub-housing 400 can be fixed to the wall 440 such that the front end 460, including the hole 112, is flush with the front surface 462 of the wall 440.

[0144] Figure 31 The illustration shows a perspective front view of a module 106 fixed to a wall 440 according to an example of the present disclosure. In this example, a sub-housing 400 may be fixed within a surrounding collar 470 that mounts the sub-housing 400 to the wall 440.

[0145] Figure 32 The illustration shows a perspective front view of a module 106 fixed to wall 440 according to an example of this disclosure. This example is similar to... Figure 31 The example shown is different except that the hole 112 can be at an angle (i.e., not parallel) to the front surface 462 of the wall 440.

[0146] Figure 33 The illustration shows a perspective front view of a module 106 fixed to wall 440 according to an example of this disclosure. In this example, a shield 500 (such as a metal cylinder) is fixed to and / or fixed behind wall 440. Power supply 402 ( Figure 29 As shown, in at least one example, it is held within a shield 500. In this example, the shield 500 provides EMI shielding for the power supply 402. Additional EMI shielding (such as in the form of metal foil) may or may not extend around the power supply 402 within the shield 500.

[0147] In at least one example, the shield 500 is configured to fit into and remain within an opening formed in the wall 440. Therefore, the shield 500 can be easily installed into the wall 440.

[0148] Figure 34 A perspective rear view of a sub-housing 400 of module 106 according to an example of this disclosure is illustrated. As shown, the sub-housing 400 may include a cooling fan 510 and a plurality of 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 within the sub-housing 400 to pass through them. The cooling fan 510 and ventilation openings 512 may be used with any of the examples described herein. In an example where an EMI shield covers multiple portions of the sub-housing 400, the EMI shield does not cover the cooling fan 510 and ventilation openings 512.

[0149] The ventilation opening 512 can be sized and shaped according to EMI wavelength requirements. In at least one example, the ventilation opening 512 can be between 0.5” and 1.0”.

[0150] Figure 35 The illustration shows a perspective interior view of a washroom 220 according to an example of this disclosure. According to any of the examples described herein, the washroom 220 may include multiple UV lamps. In at least one example, a first UV lamp 104a is configured to emit UV light onto the flush handle of a toilet 222. A second UV lamp 104b is configured to emit UV light onto a countertop 224 including a sink 226 and a faucet 228. In at least one example, a third UV lamp 104c is configured to emit UV light onto a door handle. The washroom 220 may include more or fewer UV lamps than shown.

[0151] Figure 36 A schematic block diagram of a UV lamp 104 according to an example of this disclosure is shown. The UV lamp 104 can be configured to... Figure 1-35 Any of the UV lamps 104 shown and described. In at least one example, the UV lamp 104 may include one or more modules 106, such as Figure 1 As shown. As another example, the UV lamp 104 may be a single component that does not include multiple modules coupled together. The UV lamp 104 includes one or more UV light emitters 108, whether or not they are in a module.

[0152] As described herein, the UV lamp 104 includes a mounting interface 600 removably attached to and from a fixed mounting. That is, the mounting interface is configured to selectively attach to and remove from one or more fixed mountings within an area (such as inside an aircraft). The mounting interface 600 allows the UV lamp 104 to be quickly attached to and removed from fixed mountings, and to different fixed mountings. Multiple fixed mountings have a common mounting interface that allows the mounting interface 600 of the UV lamp 104 to be connected to and disconnected. The UV lamp 104 is interchangeable relative to multiple fixed mountings located within an area (such as inside an aircraft). Thus, the UV lamp 104 is a portable device that can be attached to and removed from various locations within an area. In at least one example, a system 601 for sterilizing one or more components within an area includes multiple UV lamps 104 in communication with a monitoring system 620.

[0153] UV lamp 104 is a portable component that can be securely mounted at various locations within an area (e.g., inside a vehicle). UV lamp 104 includes a mounting interface 600 configured to allow selective attachment and removal of UV lamp 104 to and from complementary fasteners. In at least one example, mounting interface 600 may include one or more latches, hooks, pins, sockets, interference fit structures, etc., configured to be removably coupled to mutually characteristic features of the fastener. As an example, mounting interface 600 may include flanges, collars, etc., configured to insert into, or vice versa, complementary sockets, etc., of the fastener. In this way, UV lamp 104 can be selectively positioned and removed from various locations within the area. Fasteners can be secured to specific locations using fasteners, adhesives, etc. In at least one example, multiple fasteners are positioned throughout an area such as the interior compartment of a vehicle.

[0154] In at least one example, the UV lamp 104 includes a control unit 118, which communicates, for example, with one or more UV light emitters 108, one or more sensors 602, a position detector 604, and a communication device 606 via one or more wired or wireless connections. The control unit 118 is also coupled to a memory 608. In at least one example, the control unit 118 includes a memory 608. In at least one other example, the control unit 118 may be located remotely from the UV lamp 104, such as within a monitoring subsystem communicating with the UV lamp 104 (in at least one example, a computing device, such as a smartphone or smart table, laptop computer, computer workstation, etc.).

[0155] Optionally, in at least one example, the UV lamp 104 permanently fixed to a location may include a sensor 602, a position detector 604, and a communication device 606. That is, in some examples, the UV lamp 104 may be removably or non-removably fixed to a fixed mount. Such a UV lamp 104 may be configured to communicate with other UV lamps 104, with an external management system, and as per [the relevant information] Figure 36-41 They are controlled as described, whether they are interchangeable, removably fixed, or permanently fixed in place.

[0156] The control unit 118 is configured to control the operation of one or more UV light emitters 108 to sterilize components, as described herein.

[0157] The control unit 118 communicates with one or more sensors and is configured to receive a presence signal 610 from one or more sensors, such as a presence sensor. The presence signal 610 indicates the presence and / or movement of an individual, object, etc., near the UV lamp 104 (such as within the UV sterilization range of one or more UV light emitters 108). In at least one example, the sensor(s) 602 include an infrared sensor, an ultrasonic sensor, a camera, a proximity sensor, etc.

[0158] The control unit 118 communicates with the position detector 604 and is configured to receive a position signal from the position detector 604. The position signal indicates the position of the UV lamp 104 within an area such as the interior compartment of a vehicle. In at least one example, the position detector may be a radio frequency identification (RFID) chip, a global positioning system (GPS) device, a local positioning system device configured to detect position via triangulation, an electromagnetic detector communicating with an electromagnetic generator, etc.

[0159] The control unit 118 communicates with the communication device 606 and is configured to communicate with various other devices via communication. In at least one example, the communication device 606 may be one or more antennas, transceivers, Bluetooth devices, WiFi devices, etc.

[0160] UV lamp 104 provides a completely self-contained, portable, and universal UV system. UV lamp 104 can be installed or retrofitted to any area, such as the interior of a vehicle, via mounting interface 600. In at least one example, UV lamp 104 can be selectively fixed to and removed from complementary mountings in and out of the aircraft's cockpit, crew rest area, galley, main cabin, lavatory, cargo area, assembly area, and other areas within the interior cabin.

[0161] In operation, control unit 118 receives presence signals 610 from one or more sensors 602. Control unit 118 determines the presence of an individual near UV lamp 104 (e.g., within the sterilization range of one or more UV light emitters 108). In at least one example, control unit 118 controls the power level, irradiance level, intensity level, etc., of one or more UV light emitters 108 based on the frequency of movement within the area near UV lamp 104. In at least one example, control unit 118 controls the power level of the UV light based on occupancy in the irradiated area of ​​UV light emitter 108 as detected by presence signals 610 received from one or more sensors 602. Thus, the battery power of UV lamp 104 is conserved, and ozone generation can be limited because control unit 118 can modulate the power level of one or more UV light emitters 108 if the area near UV lamp 104 is not frequently occupied by individuals. That is, the less the area near UV lamp 104 is occupied by individuals, the more the control unit 118 can reduce the power level of UV light emitters 108 during sterilization cycles (e.g., when no individuals are present). Conversely, the more an individual occupies the area near the UV lamp 104, the more the control unit 118 can increase the power level of the UV light emitter 108 during the sterilization cycle.

[0162] Control unit 118 can store presence data determined based on presence signal 610 in memory 608. Control unit 118 can analyze presence data to determine the frequency of movement (in at least one example, individual occupancy) over time (week, month, year, or longer). In this way, control unit 118 can be an intelligent unit that learns from past human activity in the area (and other factors such as flight routes, passenger load, etc.) and predicts when a certain amount of UV light emitted by one or more UV light emitters 108 will be needed. Therefore, control unit 118 can predict the future operation of UV light emitters 108 based on presence data such as that which can be stored in memory 608. Therefore, control unit 118 can adjust irradiation values ​​and times for optimal sterilization and safety based on presence data stored in memory 608.

[0163] Additionally, control unit 118 receives one or more position signals 612 from position detector 604. Position signals 612 indicate the position of UV lamp 104 within an area such as the interior cab of a vehicle. Position signals 612 allow control unit 118 to determine the position of UV lamp 104 within that area. In at least one example, control unit 118 determines the position of UV lamp 104 within the area using position signals 612 received from position detector 604, and controls the power, irradiance level, and duration of UV light emission from one or more UV light emitters 108 based on the determined position of UV lamp 104. In at least one example, when UV lamp 104 is in a lavatory, control unit 118 may operate one or more UV light emitters 108 at a first power for a first time period. When UV lamp 104 is in a different area (such as a cargo area, kitchen, cab, etc.) where the same sterilization level may not be required, control unit 118 may operate UV light emitters 108 at a second power for a second time period, the second power being less than the first power and the second time period being less than the first time period.

[0164] As an example, any number of UV lamps 104 can be installed at various locations within an area, such as inside an aircraft cabin. A position detector 604 detects the position of the UV lamp 104 and outputs a position signal 612 to a control unit 118, allowing the control unit 118 of the corresponding UV lamp 104 to determine the location of the UV lamp 104 within the area. The control unit 118 of each UV lamp 104 can analyze mapping data, such as that stored in memory 608 and / or another memory in communication with the control unit 118, to apply logical or physical mapping to determine the environment of the UV lamp 104 within an area (such as a lavatory, galley, cockpit, crew rest area, passenger rows, etc.). Based on the detected position of the UV lamp, the control unit 118 (e.g., via data stored in memory 608) is programmed to control one or more UV light emitters 108 to emit UV light with specific irradiance and / or time periods. The control parameters (such as power, irradiation level, time period, etc.) for one or more UV light emitters 108 within a location stored in memory 608 can be based on the type of surface material to be treated, the area to be sterilized and / or the amount of air, the usage time interval based on known or predicted occupancy, etc. Therefore, control unit 118 can dynamically control one or more UV light emitters 108 based on the detected location of UV lamp 104.

[0165] In another example, such as when the position detector 604 is an RFID reader, chip, etc., once the UV lamp 104 is coupled to a specific fixed installation within the area, the control unit 118 can determine the position of the UV lamp 104 and thus control the UV lamp 104 accordingly, as described above. Such information can be shared between the UV lamp 104 and an external monitoring system for power management of the UV lamp 104, especially when the UV lamp 104 draws power from the aircraft (and / or when battery power is low).

[0166] In the example, UV lamp 104 may include a UV light emitter 108 configured to emit UV light of different wavelengths (222 nm, 254 nm, etc. in at least one example). Control unit 118 may operate different UV light emitters 108 based on the detected location of UV lamp 104 (e.g., detected by location detector 604) and / or the presence and / or frequency of individuals within the location of UV lamp 104 (e.g., detected by one or more sensors 602). In at least one example, different wavelengths of UV light may be emitted from one or more UV light emitters 108 based on sensed and / or predicted behavior within the location of UV lamp 104. In at least one example, control unit 118 may operate UV light emitters 108 to emit a first wavelength (e.g., 254 nm) of UV light when no individual is present at the location, and to emit a second wavelength (e.g., 222 nm) of UV light when an individual is present at the location. Selective control of different UV light emitters 108 may also be based on a specific location of the UV lamp 104 within an area.

[0167] In at least one example, the UV lamp 104 may have scalable and / or programmable power control to account for future pathogens, different or new light emitters, applications, locations, etc. For example, in a certain mode (which may be reduced to 222nm, 254nm, etc. with a certain waveform), and when individuals are present, the control unit 118 may switch to another mode, such as 222nm, based on sensed and / or known human occupancy parameters. Thus, the power supply can be controlled accordingly, as the control unit 118 can selectively control the power level, such as by reducing the power level at certain times during use with different light emitters 108.

[0168] In one example, a feedback loop can be used to determine the direction and power of irradiation, and the control unit 118 can control the power supply accordingly. This is useful when the UV lamp 104 includes an optional auxiliary power supply (such as a battery or USB power), as the power output of one or more UV light emitters 108 can be varied. In at least one example, where the UV lamp 104 has a 120V input voltage from a battery but is also capable of providing a 170V AC input voltage, the control unit 118 can control the power output by adjusting the sensed duty cycle and frequency of one or more UV light emitters 108. In this case, the output of the light emitters 108 can be sensed (in at least one example, via a photoelectric sensor 614 communicating with the control unit 118), and the control unit 118 can adjust the power supply accordingly. The photoelectric sensor 614 can be on and / or within the UV lamp 104, or mounted elsewhere in that area. Therefore, the control unit 118 can change the dose time and / or the signal to the lamp based on the sensed output voltage.

[0169] In at least one example, the communication device 606 of the UV lamp 104 can be used to communicate data with other UV lamps 104, such as those inside the aircraft cabin, and / or with external systems that receive data for processing for various reasons (such as providing information about health, battery power, sensed passenger behavior, etc., to crew, airlines, maintenance, etc.), determining which unit has a specific battery level for exchange based on location, usage, sensed or known human behavior, power level, etc. The external monitoring system 620 can provide information on how to correct potential problems with the UV lamps 104 and potential problems with total ozone production by the UV lamps 104. The external monitoring system 620 can then control certain UV lamps 104 based on various factors (ozone, behavior, etc., in at least one example). Users may have the option to set specific thresholds for each UV lamp 104 based on data generated and processed in real time from all or some of the UV lamps 104. The use of UV lamps 104 inside the aircraft cabin can be optimized for a given aircraft or fleet and the route requirements of that particular aircraft (and seasonal usage, passenger capacity, etc., in at least one example). Therefore, the control unit 622 of the monitoring system 620 can sense data, collect data, and learn from the data to control the UV lamp 104.

[0170] In at least one example, the UV lamp 104 can be dynamically mounted in areas such as the interior compartments of an aircraft, such as to a movable arm and / or robotic arm, such as within the aircraft's flight apparatus. As another example, a charging and / or data trolley (or other external system) can be used to dock and charge the UV lamp 104 during flight, turn times, etc., to download and / or upload data about the UV lamp 104. This further allows for the scalability or reprogramming of the UV module, which may have been learned by one or more UV lamps 104 during use based on changing behaviors, needs, etc. The UV lamp 104 can also be combined with a camera to identify damage or foreign debris at a location, to monitor conditions over time, and / or to address in-flight cleaning issues (such as low-cost goods, soap, etc.).

[0171] In at least one example, the UV lamp 104 includes an internal power source (such as a battery, one or more capacitors, etc.) that can be replaced or recharged. In at least one example, the UV lamp 104 can be plugged into a USB power source and recharged on a continuous basis. During a disinfection cycle, the UV lamp 104 can be configured to use both battery and USB power when power is required. Alternatively, for a specific duty cycle, the UV lamp 104 can be powered infrequently from a combination of USB / 120V power and battery power.

[0174] UV lamp 104 includes a housing 646, which includes a mounting interface 600. The mounting interface 600 is configured to be removably secured to a complementary mounting interface 648 of a fixed mount 640. In at least one example, the mounting interface 600 may be configured to be snap-fit, latch-lock, or otherwise removably secured to the mounting interface 648.

[0175] In at least one example, housing 646 holds power source 648, such as an input to the main power supply within the vehicle. Housing 646 may also hold auxiliary power source 650, such as one or more batteries, a USB port, etc., separate from and distinct from power source 648. In at least one example, UV light emitter 108 is disposed within a plurality of modules 106.

[0176] The control unit 118 is also held by the housing 646. The sensor 602 and the position detector 604 are also held by the housing 646.

[0177] Figure 39 The illustration shows a perspective view of a UV lamp 104 within a lavatory 670 according to an example of this disclosure. As described above, the UV lamp 104 can communicate with a monitoring system 620 (such as an aircraft management system) located remotely from the UV lamp 104. The UV lamp 104 is configured to output one or more position signals 672 to the monitoring system 620. The monitoring system 620 receives the position signals 672 and determines the position of the UV lamp 104 based on the position signals 672. As described above, the monitoring system 620 can operate the UV lamp 104 based on the detected position of the UV lamp 104.

[0178] Figure 40 The illustration shows a system for controlling a plurality of UV lamps 104a, 104b, 104c, 104d, and 104e within an area 700 according to an example of this disclosure.

[0179] UV lamps 104a-e are capable of communicating with each other, for example, through appropriate communication devices and external systems (such as aircraft computer system 620a, external computer system 620b, local trolley computer system 620c, etc.).

[0180] UV lamps 104a-e are capable of detecting their position within area 700, as described above. As also described above, UV lamps 104a-e are configured to predict sterilization requirements for their respective locations based on their position, movement frequency within the area, etc. UV lamps 104a-e can communicate with each other and with external systems 620a-c to provide information regarding power usage, data transmission, functionality, scalability, etc.

Optionally, the propulsion system 1212 may include more engines 1214 than shown. The engines 1214 may be carried by the wings 1216 of the aircraft 1210. In other examples, the engines 1214 may be carried by the fuselage 1218 and / or the tail 1220. The tail 1220 may also support a horizontal stabilizer 1222 and a vertical stabilizer 1224.

The interior compartment 1230 can be located within the fuselage 1232 of the aircraft (such as...). Figure 42 The interior compartment 1230 is located within the fuselage 1218.
