Patent Description:
Vehicles such as commercial aircraft are used to transport passengers between various locations. Systems are currently being developed to disinfect or otherwise sanitize surfaces within aircraft, for example, that use ultraviolet (UV) light.

A UV light sanitizing system typically includes a UV lamp that includes a plurality of UV light emitters. The UV lamp is formed by integrating the various UV light emitters into a single housing and coupling the UV light emitters to a separate power supply.

When a UV light sanitizing system is installed at a location, such as within a lavatory of an internal cabin of a vehicle, one or more UV lamps of the system need to be aligned to ensure a desired amount of UV illumination at a target surface. However, certain locations include occupancy sensors that preclude an installation technician from being therein when UV light is emitted. For example, certain lavatories within aircraft include sensors that prevent UV lamps from emitting UV light when the lavatories are occupied.

In such a setting, a UV light irradiance meter typically cannot be read directly when during testing. A meter would need to be placed in a targeted location, and then an installation technician would leave the room to illuminate the light and record the reading. However, the system may not be well aligned, thereby requiring the installation technician to make adjustments based upon an estimate of the alignment and retest.

As can be appreciated, such an alignment process may not allow for adequate validation of desired UV illumination, irradiance, and alignment of UV light emitters of a UV lamp.

<CIT>, in accordance with its abstract, states an illuminometer as one example of photometric equipment is equipped with a photodetecting element etc., of a photodetection part which measures light, a RAM of a photodetection-side control part which integrates and stores an illuminance value L as a measured value, and integrates and stores a measurement time T, and a CPU of the photodetection-side control part which divides an integral illumination value Lsum as the integral value of the measured values by an integral measurement time ΣT as the integral value of the measurement time. Consequently, the time average value Lave of the measured values in a certain specific time section can be found. <CIT> also states, in accordance with a machine translation of its description, "a photometric device capable of storing an integrated value of a measurement value and an integrated value of a measurement time by a photometric sensor for measuring. ultraviolet light. suitable for, for example. an ultraviolet intensity meter".

<CIT>, in accordance with its abstract, states an approach for the treatment of surfaces in public places with ultraviolet light. A disinfection illuminator having ultraviolet radiation sources can irradiate a number of contact surfaces. A control unit can control the ultraviolet irradiation of the contact surfaces. The disinfection illuminator is suitable for a wide variety of devices that are used by the general public. Gas station pumps, door knobs, key pads, and bathrooms are illustrative of examples of some devices and places having commonly-used surfaces that can be treated by the disinfection illuminator. <CIT> also states, in accordance with its description, "Other sensors that are suitable for use with the set of sensors. in the mounting station enclosure. can include, but are not limited to. a radiation sensor (e.g., an ultraviolet dose counter or meter)". <CIT> also states, in accordance with its description, "the analysis program. can enable the computer system. to operate the ultraviolet radiation source(s). to generate and direct ultraviolet radiation towards a user contact surface and process data corresponding to one or more attributes, which can be acquired by the sensor(s)". <CIT> also states, in accordance with its description, "during an initial period of operation, the computer system. can acquire data from at least one of the sensor(s). regarding one or more attributes of a surface and surface environment, and generate data. for further processing. can include information regarding. an amount of radiation (e.g., ultraviolet, infrared, visible, and/or microwave) detected, and/or the like. The computer system. can use the data. to control one or more aspects of the ultraviolet radiation generated by the ultraviolet radiation source(s). during a disinfection treatment".

<CIT>, in accordance with its abstract, states a sterilization system consisting of a mobile emitter, a sensing subsystem and a data logging subsystem is described. The emitter has one or more UV emitting lamps or devices. The sensing system comprises at least one remote UV sensor and at least one door sensor. The door sensor comprises a safety shut off door detector and may contain an emergency stop detector and arming detector to protect people from being exposed to UV energy. The system has a remote control for starting, stopping and setting system parameters which include but are not limited to: treatment time, dosage, room size, room number, unit number, floor, facility name, operator name, operator identification number, password, default dosage values, dosage, and patient identification number. The number of treatments per unit of time can be maximized because of the use of incident light measurement. <CIT> also states, in accordance with its description, "Central computer. may receive the UV sensors' transmissions at the programmed transmission times and then calculate the time difference between receptions of information from each individual sensor in order to integrate the total incident light energy from each sensor and ensure that at least the prescribed dosage has been delivered to each particular sensor location". <CIT> also states, in accordance with its description, "An integral part of the sterilization system is the data logging and reporting performed by central computer. Data logging provides various capabilities to this system, such as. how effectively rooms are disinfected".

In the paper Sterilization of sea lice eggs with ultraviolet C light: towards a new preventative technique for aquaculture by <NPL>, there is described a study of exposing salmon lice eggstrings to a range of UVC intensities and durations to identify effective doses. The paper states "three <NUM> W mercury UVC lamps (<NUM>) were located at one end of the raceway, housed within an open box lined with reflective material to direct light toward the raceway". The paper also states "To quantify UVC light attenuation, and thus estimate UVC intensity at a given distance from the light source. a germicidal UVC sensor (PMA2122-WP, Solar Light, PA; sensitivity: <NUM>, <NUM> bandwidth; range: <NUM>-<NUM>µW cm-<NUM>). and datalogging radiometer (PMA2100, Solar Light, PA, USA) to measure the maximum UVC intensity at <NUM> intervals from the light source from <NUM> to <NUM> in a raceway filled with seawater (<NUM> temperature, <NUM>‰ salinity, <NUM>/L oxygen)".

A need exists for a system and a method of aligning a UV lamp within a setting that may not allow for an individual to be present.

With that need in mind, certain examples of the present disclosure provide a system for verifying a desired alignment of an UV lamp with respect to a target component. The system includes a housing. A UV sensor is coupled to the housing. The UV sensor is configured to detect UV light emitted from one or more UV light emitters of the UV lamp and output one or more signals indicative of the UV light. A UV recorder is coupled to the housing. The UV recorder is in communication with the UV sensor. The UV recorder is configured to receive the one or more signals from the UV sensor and store data regarding the one or more signals. A pointer extends from the housing. The pointer is configured to assist in aligning the UV sensor with the one or more UV light emitters.

In some examples, the pointer is moveable between a retracted position and an extended position. In further examples, the pointer is configured to linearly move between the retracted position and the extended position. In further examples, the pointer is a telescoping arm having a plurality of telescoping segments.

In at least one example, the system also includes a battery or is otherwise connectable to a power source.

In at least one example, the system also includes a stand connected to the housing. For example, the stand includes a base, and a connection joint that connects to the housing. The connection joint allows the housing to move relative to the stand.

In at least one example, the UV recorder comprises a control unit that receives the one or more signals.

Certain examples of the present disclosure provide a method for verifying a desired alignment of an UV lamp with respect to a target component. The method includes detecting, by a UV sensor coupled to a housing, UV light emitted from one or more UV light emitters of the UV lamp; outputting, by the UV sensor, one or more signals indicative of the UV light; receiving, by a UV recorder coupled to the housing and in communication with the UV sensor, the one or more signals from the UV sensor; storing, by the UV record, data regarding the one or more signals; and using a pointer extending from the housing to assist in aligning the UV sensor with the one or more UV light emitters.

Certain examples of the present disclosure provide an enclosed space including a target component, an UV lamp including one or more UV light emitters, and a system for verifying a desired alignment of the UV lamp with respect to the target component, as described herein.

Certain examples of the present disclosure provide a system for disinfecting (for example, sanitizing, decontaminating, cleaning, or the like) one or more components. The system includes a plurality of modules coupled together to form a UV lamp. Each of the plurality of modules includes one or more UV light emitters that are configured to emit UV light onto a component to disinfect the component. In at least one example, each of the modules also includes a power supply coupled to the UV light emitters. The modules can also include a band pass filter that is configured to filter the generated UV light from the UV light emitters to a desired wavelength, such as within the far UV spectrum, the UVC spectrum, or the like. In at least one example, different modules can emit UV light at different wavelengths. For example, a first module can emit UV light within the far UV spectrum, while a second module coupled to the first module can emit UV light within the UVC spectrum.

Multiple modules may be coupled together (for example, stacked, ganged, or otherwise connected together) as desired for a greater area of UV coverage. Such configuration can be determined based on the size of the surface to be sanitized. The modules can be coupled together through bonding, one or more mechanical connectors or fasteners, and/or the like.

The UV lamp formed by multiple modules can be customized to fit into desired areas. As such, the UV lamp can be compact and configured to fit into small, confined spaces.

Optionally, the system may not include a plurality of modules. Instead, a single UV lamp having a plurality of UV light emitters can be used with examples of the present disclosure.

In at least one example, the UV lamp is part of a wand assembly that is 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 lavatory. The UV lamp can be fixed in position within the space. Optionally, the UV lamp can be configured to be moved between a stowed position and a deployed position within the space. As another option, the UV lamp can be removably secured to a securing mount.

In at least one example, the system includes an infrared (IR) sensor in communication with a control unit. The IR sensor is configured to detect IR light, such as a beam of IR light emitted from an IR source, which can be reflected to the IR sensor. In operation, the control unit is also in communication with the one or more UV light emitters. The control unit is configured to selectively activate and deactivate the UV light emitters in response to a signal received from the IR sensor. For example, 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 the IR light.

For example, an IR source and/or an IR reflector can be positioned within a location, such as proximate to (for example, on or within a foot or less) a lavatory door. The IR sensor is configured to monitor the IR beam and to detect a change when an occupant crosses a threshold. Additionally the system can include a door sensor (such as a door hall effect sensor) installed on and/or proximate to the door to detect when the door is open or closed. The control unit can also be in communication with the door sensor and is configured to selectively activate and deactivate the UV light emitters in response to one or more IR signals received from the IR sensor and/or the door sensor.

In at least one example, the control unit is configured to deactivate the UV light emitters when an area (such as a lavatory) is occupied, and to activate the UV light emitters when the area is unoccupied. Integrating the IR sensor into the UV lamp reduces cost and installation time.

Certain examples of the present disclosure provide a sanitizing system and method that includes an ultraviolet (UV) lamp (such as an excimer lamp having one or more UV light emitters, such as light emitting diodes, bulbs, and/or the like) that emits UV light in a far UV light spectrum, such as at a wavelength of <NUM>, which neutralizes (such as kills) microbes (for example, viruses and bacteria), while posing no risk to humans. Optionally, the UV lamp emits the UV light in the UVC spectrum, such as at a wavelength of <NUM>. The UV lamp may be used within an internal cabin to decontaminate and kill pathogens. The UV lamp may be used in a portable sanitizing system or a fixed sanitizing system. For example, operating the UV lamp to emit sanitizing UV light having a wavelength within the far UV spectrum or UVC spectrum may be used with a portable system or a fixed system.

Certain examples of the present disclosure provide an alignment test system that ensures proper alignment of UV lamps, such as in spaces that are to be unoccupied during testing. The alignment is used to ensure a proper UV illumination with respect to a target. The alignment systems and methods allow an individual (such as an installation technician testing a UV system) to leave a room having a UV lamp while the alignment system validates that the UV light emitters of the UV lamp are in a desired alignment to provide a desired UV radiance in relation to a target component.

In at least one example, the system includes a UV sensor, an attachable base, and an extendable element to ensure proper alignment prior to activating the UV lamp. The alignment system allows for the UV lamp to be aligned as desired after a first test, in contrast to a trial and error approach. As such, the alignment systems and methods reduce installation and testing times, and improve disinfecting UV irradiance in relation to a component.

Certain examples of the present disclosure provide an alignment test system to verify a UV lamp is providing a correct UV illumination to a targeted surface. The alignment system includes a housing that contains a UV sensor, a UV recorder, a rechargeable battery, and an extendable pointer. The alignment system can also include a stand attached to the housing, and a weighted base. In at least one example, the stand includes a ball joint or other rotational joint to allow rotation of the housing. The base may also include a suction cup or non-permanent sticky tape to facilitate stability of the base. The alignment systems and methods are particularly well-suited for spaces that have an occupancy sensor that prevents UV illumination when occupied.

In at least one example, the alignment system is placed on an object or surface to record the UV irradiance emitted from a UV lamp. The pointer is extended to ensure alignment of the UV sensor with the UV lamp. The operator may then turn on the UV recorder and exit the area. The UV light turns on once the room/area is not occupied. The UV sensor detects the intensity of UV radiation and connects to the recorder to output the electrical signal which varies with the UV intensity. In at least one example, the sensor is powered by a microprocessor driven data recorder. The recorder documents the data which can be downloaded onto a laptop or other device. Optionally, the sensor could have a low pass filter to filter out all optical light and only allow detection of UV light. The operator reads the UV irradiance stored in the recorder to validate the installation irradiance.

<FIG> illustrates a schematic block diagram of a system <NUM> for disinfecting a component <NUM>, according to an example of the present disclosure. The component <NUM> can be any structure that is to be disinfected with UV light. For example, the component <NUM> can be a structure within a vehicle, a fixed building, or the like. In some examples, the component <NUM> can be a passenger seat within a vehicle, a portion of a lavatory (such as a toilet, sink, door handle, and/or the like), a counter or other such surface within a kitchen or galley, and/or the like.

The system <NUM> includes a UV lamp <NUM> that includes a plurality of modules <NUM> coupled together. For example, the UV lamp <NUM> includes a first module <NUM> coupled to a second module <NUM>. Optionally, the UV lamp <NUM> can include more than two modules <NUM>.

Each module <NUM> includes one or more UV light emitters <NUM> that are configured to emit UV light through an aperture <NUM>. The UV light emitters <NUM> can emit UV light within the far UV spectrum, such as between <NUM> nanometers (nm) - <NUM>. For example, the UV light emitters can emit UV light at <NUM>. In other examples, the UV light emitters <NUM> can emit UV light within the UVC spectrum, such as between <NUM> and <NUM>. For example, the UV light emitters can emit UV light at <NUM>. In at least one example, the UV light emitters <NUM> of the modules <NUM> emit UV light at the same wavelength. In at least one other example, the UV light emitters <NUM> of the modules <NUM> emit UV light at different wavelengths. For example, the UV light emitters <NUM> of a first module <NUM> emit UV light within the far UV spectrum, and the UV light emitters <NUM> of a second module <NUM> emit UV light within the UVC spectrum, or vice versa.

The modules <NUM> are coupled together to form the light emitting portion of the UV lamp <NUM>. The modules <NUM> can be removably coupled together. As such, the UV lamp <NUM> provides a modular assembly that can be customized to a desired size, shape, and lighting capability. Further, if a module <NUM> is in need of repair, the module <NUM> can be removed from the UV lamp <NUM> and replaced within another module <NUM>. Accordingly, the modules <NUM> allow for efficient production and maintenance of the UV lamp <NUM>.

In at least one example, portions of the modules <NUM> are covered with one or more electromagnetic interference (EMI) shields <NUM>. For example, in at least one example, the one or more UV light emitters <NUM> are surrounded on one or more surfaces with an EMI shield <NUM>, with the aperture <NUM> being uncovered by the EMI shield <NUM>. In at least one example, the EMI shield <NUM> is a metal cover, such as a foil formed of aluminum, steel, or the like that covers a housing of the module <NUM> with the aperture <NUM> remaining uncovered. Optionally, the modules <NUM> do not include the EMI shield <NUM>.

The UV lamp <NUM> can be part of a wand assembly, which is configured to be held by an individual. The wand assembly can be coupled to a backpack assembly, a case assembly, a cart, and/or the like. In other examples, the wand assembly can be a standalone assembly that is not coupled to a backpack assembly, a case assembly, a cart, or the like.

In other examples, the UV lamp <NUM> can be a fixture within an area. For example, the UV lamp <NUM> can be secured within a lavatory, galley, kitchen, or various other areas. The UV lamp <NUM> can be fixed in position within the area. Optionally, the UV lamp <NUM> can be moveable between a stowed position and a deployed position within the area. In at least one other example, the UV lamp <NUM> can be removably securable to various structures, such as securing mounts located within an area, such as within a vehicle.

In at least one example, the system <NUM> also includes an infrared (IR) sensor <NUM> in communication with a control unit <NUM>, such as through one or more wired or wireless connections. The control unit <NUM> is also in communication with the UV light emitters <NUM> of the modules <NUM>, such as through one or more wired or wireless connections. In at least one example, the UV lamp <NUM> includes the IR sensor <NUM> and/or the control unit <NUM>. Optionally, the IR sensor <NUM> and/or the control unit <NUM> can be remotely located from the UV lamp <NUM>.

In operation, the control unit <NUM> selectively activates and deactivates the UV light emitters <NUM> based on an IR signal emitted by and received from the IR sensor <NUM>. For example, the IR sensor <NUM> is configured to receive an IR light signal <NUM> emitted by an IR source <NUM>, either directly from the IR source <NUM>, or indirectly from a reflector that receives and reflects the IR light signal <NUM> from the IR source <NUM>. When the IR sensor <NUM> receives the IR light signal <NUM>, the IR sensor <NUM> outputs a sensed IR signal <NUM> to the control unit <NUM>. Based on the received sensed IR signal <NUM>, the control unit <NUM> activates the one or more UV light emitters <NUM> to emit the UV light. If, however, the IR sensors <NUM> does not receive the IR light signal <NUM> (such as if the IR light signal <NUM> is blocked by an individual), the IR sensor does not output the sensed IR signal <NUM> to the control unit <NUM>. In response to not receiving the sensed IR signal <NUM>, the control unit <NUM> deactivates the UV light emitters <NUM> so that they do not emit the UV light.

In at least one example, an activation switch <NUM> is in communication with the control unit <NUM>, such as through one or more wired or wireless connections. The activation switch <NUM> can be secured to the UV lamp <NUM>. That is, the UV lamp <NUM> can include the activation switch <NUM>. Optionally, the activation switch <NUM> can be remotely located from the UV lamp <NUM>. When the activation switch <NUM> is engaged to activate the UV light emitters <NUM>, the control unit <NUM> operates as explained above (that is, the control unit <NUM> selectively activates and deactivates the UV light emitters based on the signal received from the IR sensor <NUM>). When the activation switch <NUM> is disengaged so that the UV light emitters <NUM> are not to emit the UV light, the control unit <NUM> maintains the UV light emitters <NUM> in a deactivated state even if the sensed IR signal <NUM> is received from the IR sensor <NUM>. Optionally, the system <NUM> may not include the activation switch.

In at least one example, the system <NUM> includes the UV lamp <NUM> having UV light emitters <NUM> whether or not within the modules <NUM>. For example, the UV lamp <NUM> can be a single, non-modular assembly that is in communication with the control unit <NUM>, which selectively activates and deactivates the UV light emitters <NUM> as described herein. In at least one other example, the system <NUM> does not include the IR sensor <NUM> or the IR source <NUM>.

As such, the first module 106a and the second module 106b can be efficiently coupled together. Further, the first module 106a and the second module 106b can be disconnected, such as if one of the first module <NUM> or the second module 106b is in need of repair or is to be replaced.

<FIG> illustrates a perspective end view of a module <NUM>, according to example of the present disclosure. <FIG> illustrates a perspective top view of the module <NUM> of <FIG> illustrates a perspective bottom view of the module <NUM> of <FIG>. Referring to <FIG>, for the sake of clarity, certain outer wall portions of the module <NUM> are not shown in order show internal components.

In at least one example, the housing <NUM> includes a bracket <NUM> having a platform <NUM> extending between opposite side walls <NUM> and <NUM>. The platform <NUM> includes an upper surface <NUM> opposite from a lower surface <NUM>. A dividing wall <NUM> upwardly extends from the upper surface <NUM>. A first power chamber <NUM> is defined between the upper surface <NUM>, an interior surface <NUM> of the side wall <NUM>, and a first side surface <NUM> of the dividing wall <NUM>. A second power chamber <NUM> is defined between the upper surface <NUM>, an interior surface <NUM> of the side wall <NUM>, and a second side surface <NUM> (opposite from the first side surface <NUM>) of the dividing wall <NUM>.

Referring to <FIG>, the first power supply <NUM> and the second power supply <NUM> may be batteries and/or electrical power interfaces, connections, and/or the like that are configured to provide power to the UV light emitters <NUM>.

In at least one example, a frame <NUM> is secured within the emitter chamber <NUM>, such as via one or more fasteners, bonding, and/or the like. The frame <NUM> retains the first sub-housing <NUM> and the second sub-housing <NUM>. The UV light emitters <NUM> of the first sub-housing <NUM> and the second sub-housing <NUM> are electrically coupled to the first power supply <NUM> and the second power supply <NUM>, respectively, such as through wires that pass through slots, channels, or other such openings formed in the platform <NUM>.

The platform <NUM> separates and isolates the frame <NUM> (including the UV light emitters <NUM>) from the first power supply <NUM> and the second power supply <NUM>. Further, the dividing wall <NUM> separates and isolates first power supply <NUM> from the second power supply <NUM>. In at least one example, the first power supply <NUM> and the second power supply <NUM> can be high voltage power supplies (such as <NUM> kV), and therefore the separation and isolation therebetween and in relation to the frame <NUM> ensures reliable and efficient operation.

As shown, the first power supply <NUM> and the second power supply <NUM> are stacked above the frame <NUM>, which retains the first sub-housing <NUM> and the second sub-housing <NUM>. Optionally, a single power supply can be used to provide power to the UV light emitters <NUM> of the first sub-housing <NUM> and the second sub-housing <NUM>. In at least one example, the bracket <NUM> may not include the dividing wall <NUM>. In at least one other example, the power supply (supplies) can be remote from the module <NUM>.

<FIG> illustrates a perspective bottom view of the bracket <NUM>, according to an example of the present disclosure. <FIG> illustrates a perspective top view of the bracket <NUM> of <FIG>. Referring to <FIG>, the bracket <NUM> can include one or more passages <NUM> (such as slots) formed through the platform <NUM>. Referring to <FIG>, the passages <NUM> allow for wiring to be routed between the UV light emitters <NUM> and the power supplies <NUM> and/or <NUM>, for example. Optionally, the bracket <NUM> may not include the passages <NUM>. Instead, wiring can be routed around end edges of the platform <NUM>, for example.

As shown, the side walls <NUM> and <NUM> can includes inwardly-canted segments <NUM> and <NUM>, respectively, bounding the first power chamber <NUM> and the second power chamber <NUM>, respectively. Free ends of the inwardly-canted segments angle toward the dividing wall <NUM>. The inwardly-canted segments <NUM> and <NUM> provide a more compact bracket <NUM>, which takes up less space. Optionally, the side walls <NUM> and <NUM> can also, or alternatively, include inwardly-canted segments. Alternatively, the bracket <NUM> may not include inwardly-canted segments.

<FIG> illustrates a bottom view of a plurality of modules 106a, 106b, and 106c coupled together, according to an example of the present disclosure. A first end 140a of the module 106a is secured to a second end 142b of the module 106b. A first end 140b of the module 106b is secured to a second end 142c of the module 106c.

In at least one example, the battery <NUM> is configured to mate with a power cord <NUM> to be recharged.

<FIG> illustrates a bottom view of the UV lamp <NUM> having a plurality of modules <NUM>, according to an example of the present disclosure. In this example, the UV lamp <NUM> may not include a battery. Instead, the UV lamp receives power from the power cord <NUM>.

<FIG> illustrates a perspective lateral view of a wand assembly <NUM> including the UV lamp <NUM>, according to an example of the present disclosure. <FIG> illustrates a bottom view of the wand assembly of <FIG>. Referring to <FIG>, the wand assembly <NUM> includes a sanitizing head <NUM> coupled to a handle <NUM>. The sanitizing head <NUM> includes a shroud <NUM> that retains the UV lamp <NUM>. The battery <NUM> can be retained within the shroud <NUM>.

In at least one example, the sanitizing head <NUM> is configured to move relative to the handle <NUM>. For example, the sanitizing head <NUM> can be extended and/or rotated relative to the handle <NUM>. In at least one other example, the sanitizing head <NUM> is fixed in relation to the handle <NUM>. The wand assembly <NUM> can include the UV lamp <NUM> having a plurality of modules <NUM>, as described with respect to any of <FIG>.

<FIG> illustrates a perspective internal view of a lavatory <NUM>, according to an example of the present disclosure. The lavatory <NUM> may be within an internal cabin of a vehicle, such as a commercial aircraft. The lavatory <NUM> includes a toilet <NUM> and a counter <NUM> having a sink <NUM> and faucet <NUM>. One or more UV lamps <NUM> are disposed within the lavatory <NUM>. The UV lamps <NUM> are configured as described with respect to any of <FIG>.

The UV lamps <NUM> are configured to emit UV light to disinfect one or more components within the lavatory <NUM>, such as the toilet <NUM>, the counter <NUM>, the sink <NUM>, the faucet <NUM>, the floor <NUM>, one or more walls <NUM>, and/or the like. In at least one example, the UV lamps <NUM> can be fixed in position. In at least one other example, the UV lamps <NUM> can be configured to move. For example, the UV lamps <NUM> can be moved between stowed positions and deployed positions.

<FIG> illustrates a perspective internal view of the lavatory <NUM>, according to an example of the present disclosure. Referring to <FIG> and <FIG>, in this example, the UV lamp <NUM> includes the IR sensor <NUM> that receives the IR light signal <NUM> from the IR source <NUM>. The IR source <NUM> is configured to emit the IR light signal <NUM> through an area in which an individual would be if occupying the lavatory <NUM>.

The IR sensor <NUM> may be aligned with the IR source <NUM> to directly receive the IR light signal <NUM> from the IR source <NUM>. Optionally, the IR source <NUM> may be configured to emit the IR light signal <NUM> at a reflector, such as a mirror, that reflect the IR light signal <NUM> to the IR source <NUM>.

The IR sensor <NUM> can be mounted directly to the UV lamp <NUM>, such as on a housing. In at least one example, the IR sensor <NUM> can be secured to a module <NUM>. In at least one example, multiple modules <NUM> include an IR sensor <NUM>. In at least one other example, the IR sensor <NUM> is remote from the UV lamp <NUM>.

As shown, the IR sensor <NUM> can be secured to an end or corner of the UV lamp <NUM>. The IR sensor <NUM> is configured to receive the IR light signal <NUM> either directly from the IR source <NUM> or indirectly from the IR source <NUM> as reflected from one or more reflectors <NUM>. The IR light signal <NUM> can be a laser or narrow non-laser optical signal, for example.

As shown, the IR light signal <NUM> is configured to extend through a portion of the lavatory <NUM> such that a person entering or exiting the room crosses the path of and interrupts the IR light signal <NUM>. As the path between the IR source <NUM> and the IR sensor <NUM> is interrupted, the IR sensor <NUM> does not receive the IR light signal <NUM>. When the IR sensor <NUM> does not receive the IR light signal <NUM>, the control unit <NUM> does not receive the sensed IR signal <NUM> from the IR sensor <NUM>. Further, the IR light signal <NUM> is directed such that an individual within the lavatory <NUM> would interrupt the IR light signal <NUM>.

The control unit <NUM> operates to ensure that the UV light emitters <NUM> are deactivated when an individual is within the lavatory <NUM> (or other such room in which the UV lamp <NUM> is used). By communicating with the IR sensor <NUM> (and optionally, the door sensor <NUM> as shown in <FIG> and <FIG>), the control unit <NUM> determines whether the room is occupied or unoccupied. If occupied, the control unit <NUM> deactivates the UV light emitters <NUM>. If unoccupied, the control unit <NUM> can activate the UV light emitters <NUM> to disinfect one or more components within the room.

<FIG> illustrates a perspective bottom view of the UV lamp <NUM>, according to an example of the present disclosure. Referring to <FIG> and <FIG>, the UV lamp <NUM><NUM> includes a housing <NUM> having a plurality of UV light emitters <NUM>, whether within modules <NUM> or not. The IR sensor <NUM> is secured to the housing <NUM> and is oriented in a direction to receive the IR light signal <NUM>.

The control unit <NUM> is in communication with the IR sensor <NUM> and the UV light emitters <NUM>. In at least one example, a door sensor <NUM> is also in communication with the control unit <NUM>, such as through one or more wired or wireless connections. For example, the door sensor <NUM> is a Hall-effect sensor. The door sensor <NUM> is configured to detect opening and closing of a door of a room, such as the lavatory <NUM> shown in <FIG> and <FIG>. The control unit <NUM> selectively activates and deactivates the UV light emitters <NUM> based on IR signals (for example reception of such IR signal(s) and lack of reception of such IR signal(s) received from the IR sensor <NUM> and door signals (for example, signals indicating that the door is open or closed) received from the door sensor <NUM>. Optionally, the control unit <NUM> is not in communication with a door sensor.

<FIG> illustrates a perspective bottom view of the UV lamp <NUM>, according to an example of the present disclosure. In this example, the IR sensor <NUM> is remotely located from the UV lamp <NUM>, and is in communication with the control unit <NUM> through one or more wired or wireless connections.

<FIG> illustrates a perspective bottom view of the UV lamp <NUM>, according to an example of the present disclosure. As shown, the housing <NUM> can include an extension <NUM>. The IR sensor <NUM> can be mounted on the extension <NUM>.

<FIG> illustrates a top plan view of the lavatory <NUM>, according to an example of the present disclosure. <FIG> illustrates a perspective internal view of the lavatory <NUM> of <FIG>. Referring to <FIG> and <FIG>, the door sensor <NUM>, such as a Hall effect sensor, is configured to cooperate with a magnet <NUM> positioned on the door <NUM> of the lavatory <NUM> to determine when the door <NUM> is opened or closed. For example, when the magnet <NUM> touches or is in close proximity (such as within <NUM> inches (<NUM>) or less) of the door sensor <NUM>, the door sensor <NUM> outputs a signal to the control unit <NUM> that the door <NUM> is closed. In at least one example, the door sensor <NUM> can be secured to the housing <NUM> of the UV lamp <NUM>.

In at least one example, the control unit <NUM> deactivates the UV light emitters <NUM> of the UV lamp <NUM> in response to the IR sensor <NUM> not receiving the sensed IR signal <NUM> from the IR sensor <NUM>. Conversely, the control unit <NUM> activates the UV light emitters <NUM> to disinfect one or more components within the lavatory <NUM> in response to receiving the sensed IR signal <NUM> from the IR sensor <NUM> and receiving a signal from the door sensor <NUM> indicating that the door <NUM> is closed. In at least one example, in response to receiving a signal from the door sensor <NUM> indicating that the door <NUM> is opened, the control unit <NUM> deactivates the UV light emitters <NUM>, even if the control unit <NUM> receives the sensed IR signal <NUM> from the IR sensor <NUM>.

<FIG> illustrates a perspective view of the IR sensor <NUM>, according to an example of the present disclosure. In at least one example, the IR sensor <NUM> includes a socket <NUM> that moveably retains a ball <NUM>. The ball <NUM> retains a sensing element <NUM> that is configured to receive and detect an IR light signal. The ball and socket configuration shown in <FIG> allows the sensing element <NUM> to be moved to a desired orientation and alignment so as to receive the IR light signal. Optionally, the IR sensor <NUM> may not include a moveable element, such as the ball <NUM> moveably retained within the socket <NUM>.

Referring to <FIG> and <FIG>, in at least one example, the control unit <NUM> activates the UV light emitters <NUM> in response to determining that the lavatory <NUM> (or other such room) is vacated and unoccupied. For example, in response to reception of a signal from the door sensor <NUM> that the door <NUM> is opened and the sensed IR light signal <NUM> for at least one second, followed by reception of a signal from the door sensor <NUM> that the door <NUM> is closed and the sensed IR light signal <NUM> for at least one additional second, the control unit <NUM> activates the UV light emitters <NUM> for a predetermined sanitizing period (such as <NUM> seconds). If the control unit <NUM> detects that the door <NUM> is opened during the sanitizing period, the control unit <NUM> immediately deactivates the UV light emitters <NUM>.

Further, if the control unit <NUM> detects that IR sensor <NUM> is not receiving the IR light signal <NUM> (such as by not receiving the sensed IR light signal <NUM> from the IR sensor), the control unit <NUM> deactivates the UV light emitters <NUM>. Such an interruption of the IR light signal <NUM> triggers a reset event, in which the control unit <NUM> may then reactivate the UV light emitters <NUM> after determining that the door <NUM> has been opened, reception of the sensed IR light signal <NUM> from the IR sensor <NUM>, the door <NUM> is subsequently closed, and further reception of the sensed IR light signal <NUM> from the IR sensor <NUM>.

<FIG> illustrates a flow chart of a method of operating a UV lamp, according to an example of the present disclosure. Referring to <FIG> and <FIG>, at <NUM>, the control unit <NUM> determines an opening of the door <NUM>, such as via a signal received from the door sensor <NUM>. At <NUM>, the control unit <NUM> determines if the sensed IR light signal <NUM> is received from the IR sensor <NUM>. If not, the method proceed to <NUM>, at which the control unit <NUM> deactivates the UV light emitters <NUM>, and the method then returns to <NUM>.

If, however, the sensed IR light signal <NUM> is received from the IR sensor <NUM> at <NUM>, the control unit <NUM> determines if the door <NUM> is closed, such as via a signal received from the door sensor <NUM>. If the door is not closed, the method returns to <NUM>.

If, however, the door <NUM> is closed, the control unit <NUM> determines if the sensed IR light signal <NUM> is received at <NUM>. If not, the method returns to <NUM>.

If, however, the control unit <NUM> determines that the sensed IR light signal <NUM> is received at <NUM>, the control unit <NUM> operates the UV lamp <NUM> at <NUM> to emit the UV light from the UV light emitters <NUM> for a predetermined sanitizing time (such as <NUM>-<NUM> seconds). If, at <NUM>, the control unit <NUM> determines that the door <NUM> is opened during the predetermined sanitizing time, the method returns to <NUM>, at which the control unit <NUM> immediately deactivates the UV light emitters <NUM>.

If, however, the door is not opened during the predetermined sanitizing time at <NUM>, the method proceeds from <NUM> to <NUM>, at which the control unit <NUM> operates the UV light emitters <NUM> to continue to emit the UV light until an expiration of the predetermined time, at which point the UV light emitters <NUM> are deactivated. The process then returns to <NUM>.

<FIG> illustrates a perspective view of a module <NUM>, according to an example of the present disclosure. The module <NUM> includes a sub-housing <NUM> retaining one or more UV light emitters <NUM>. The sub-housing <NUM> is coupled to a power supply <NUM> through a cable <NUM>. In contrast to the example shown in <FIG>, the sub-housing <NUM> and the power supply <NUM> may not be secured within a common bracket. Optionally, the sub-housing <NUM> and the power supply <NUM> may be secured to a bracket, such as the bracket <NUM> shown and described with respect to <FIG>, for example.

An EMI shield <NUM> (for example, a first EMI shield) is disposed around portions of the sub-housing <NUM>. In at least one example, the EMI shield <NUM> is disposed around all portions of the sub-housing <NUM>, except the aperture <NUM>. In some examples, the EMI shield <NUM> is a metal foil (for example, a stainless steel, aluminum, or the like foil) that extends around portions of the sub-housing <NUM>. The EMI shield <NUM> blocks, attenuates, or otherwise hinders EMI that may be generated by operation of the UV light emitters <NUM> from passing therethrough (and/or blocks EMI from passing into the sub-housing <NUM>).

The EMI shield <NUM> (for example, a second EMI shield) may also extend around portions of the power supply <NUM> and/or the cable <NUM>. For example, the EMI shield <NUM> may wrap around all portions of the power supply <NUM> and/or the cable <NUM>. In at least one example, the EMI shield <NUM> covers an entirety of the module <NUM> including the sub-housing <NUM>, the power supply <NUM>, and the cable <NUM>, except for the aperture <NUM>. The EMI shield <NUM> blocks, attenuates, or otherwise hinders EMI from passing between the sub-housing <NUM> and the power supply <NUM>.

Further, by separating the sub-housing <NUM> from the power supply <NUM> (and connecting via the cable <NUM>), the module <NUM> may be more readily integrated and used in certain confined areas in which a common housing retaining both may be too large. The sub-housing <NUM> as shown in <FIG> has a low profile and may fit into smaller spaces.

The EMI shield <NUM> may be used with any of the examples described herein. Further, a module including the sub-housing <NUM> separated from the power supply <NUM> (as shown in <FIG>) may be used with any of the examples described herein, whether with the EMI shield <NUM> or without the EMI shield <NUM>.

<FIG> illustrates a perspective bottom view of the sub-housing <NUM> of the module <NUM> of <FIG>. In at least one example, an EMI grid <NUM> is disposed within the aperture <NUM>. The EMI grid <NUM> includes a plurality of longitudinal beams <NUM> that intersect a plurality of lateral beams <NUM>, defining passages <NUM> therebetween. The beams <NUM> and <NUM> may have a thickness between <NUM>" - <NUM>" (<NUM> - <NUM>), for example. In this manner, the EMI grid <NUM> can be a mesh screen or cage, for example. The EMI grid <NUM> also hinders passage of EMI into or out of the module <NUM>. In at least one example, the EMI grid <NUM> can be formed of stainless steel. Alternatively, the module <NUM> does not include the EMI grid <NUM>.

<FIG> illustrates a lateral view of the module <NUM> of <FIG> secured to a wall <NUM>, according to an example of the present disclosure. The sub-housing <NUM> can be mounted on a first surface <NUM> (such as an outer or inner surface) of the wall <NUM>, and the power supply <NUM> can be disposed behind the wall <NUM>. For example, the power supply <NUM> can be secured behind a second surface <NUM> (opposite from the first surface) of the wall <NUM>. An opening <NUM> formed through the wall <NUM> is configured to allow the cable <NUM> to pass therethrough. In this manner, the wall <NUM> also isolates the sub-housing <NUM> from the power supply <NUM>.

The wall <NUM> may be a portion of a room. For example, the wall <NUM> may be a wall of a lavatory, such as the lavatory <NUM> shown in <FIG>, <FIG>, <FIG>, and <FIG>.

<FIG> illustrates a perspective front, lateral view of the module <NUM> secured to the wall <NUM>, according to an example of the present disclosure.

<FIG> illustrates a perspective front, lateral view of the module <NUM> secured to the wall <NUM>, according to an example of the present disclosure. In this example, the sub-housing <NUM> can be secured within a surrounding collar <NUM> that mounts the sub-housing <NUM> to the wall <NUM>.

<FIG> illustrates a perspective front, lateral view of the module <NUM> secured to the wall <NUM>, according to an example of the present disclosure. This example is similar to that shown in <FIG>, except that the apertures <NUM> may be angled (that is, not parallel) to the front surface <NUM> of the wall <NUM>.

<FIG> illustrates a perspective front view of the module <NUM> secured to the wall <NUM>, according to an example of the present disclosure. In this example, a shielding shroud <NUM>, such as a metal cylinder, is secured to and/or behind the wall <NUM>. The power supply <NUM> (shown in <FIG>, for example) is retained within the shielding shroud <NUM>. In this example, the shielding shroud <NUM> provides the EMI shielding for the power supply <NUM>. Additional EMI shielding, such as in the form of a metal foil, may nor may not extend around the power supply <NUM> within the shielding shroud <NUM>.

In at least one example, the shielding shroud <NUM> is configured to fit into and be retained within an opening formed in the wall <NUM>. As such, the shielding shroud <NUM> can be easily installed into the wall <NUM>.

<FIG> illustrates a perspective rear view of the sub-housing <NUM> of the module <NUM>, according to an example of the present disclosure. As shown, the sub-housing <NUM> may include a cooling fan <NUM> and a plurality of ventilation openings <NUM>. The cooling fan <NUM> operates to cool the UV light emitters <NUM> during operation, and the ventilation openings <NUM> draw in cooling air and/or allow air within the sub-housing <NUM> to pass therethrough. The cooling fan <NUM> and the ventilation openings <NUM> may be used with any of the examples described herein. In examples in which an EMI shield covers portions of the sub-housing <NUM>, the EMI shield does not cover the cooling fan <NUM> and the ventilation openings <NUM>.

The ventilation openings <NUM> can be sized and shaped depending on EMI wavelength requirements. For example, in at least one example, the ventilation openings <NUM> can be between <NUM>" - <NUM>" (<NUM> - <NUM>).

<FIG> illustrates a perspective internal view of the lavatory <NUM>, according to an example of the present disclosure. The lavatory <NUM> can include a plurality of UV lamps, according to any of the examples described herein. For example, a first UV lamp 104a is configured to emit UV light onto a flush handle of the toilet <NUM>. A second UV lamp 104b is configured to emit UV light onto the counter <NUM>, including the sink <NUM> and the faucet <NUM>. A third UV lamp 104c is configured to emit UV light onto a door handle, for example. The lavatory <NUM> can include more or less UV lamps than shown.

<FIG> illustrates a schematic block diagram of an alignment system <NUM> for verifying a desired alignment of an ultraviolet (UV) lamp with respect to a target component, according to an example of the present disclosure.

In at least one example, the UV recorder <NUM> includes a control unit <NUM> that receives signals indicative of sensed UV light from the UV sensor <NUM>, and records information regarding the UV light in a memory, for example.

The battery <NUM> provides power to the UV sensor <NUM> and the UV recorder <NUM>. In at least one example, the battery <NUM> is rechargeable. Optionally, the alignment system <NUM> can include an electrical plug, in addition to or in place of the battery <NUM>. The electrical plug allows the alignment system to be coupled to another source of power, such as a source of alternating current (AC) power.

The pointer <NUM> is moveable in relation to the housing <NUM>. The pointer <NUM> is configured to be linearly moved between a retracted position and an extended position. In at least one example, the pointer <NUM> is a telescoping arm including telescoping segments. In other examples, the pointer <NUM> includes slidable members that linearly slide in relation to one another. In other examples, the pointer <NUM> includes an articulating arm that is configured to extend into a fully linear position.

The connection joint <NUM> allows the housing <NUM> to be moved relative to the stand <NUM>. In at least one example, the connection joint <NUM> is or includes a ball joint. In other examples, the connection joint <NUM> can include one or more articulating or pivoting arms.

The alignment system <NUM> ensures proper alignment of a UV lamp, such as in a space that is to be unoccupied during testing. The UV lamp is aligned to ensure a proper UV illumination with respect to a target component (that is, a component that is to be disinfected by UV light emitted by the UV lamp). The alignment system <NUM> allows an individual to leave a room having the UV lamp while the alignment system <NUM> validates that the UV light emitter(s) of the UV lamp are in a desired alignment to provide a desired UV radiance in relation to the target component.

The alignment system <NUM> allows for the UV lamp to be aligned as desired after a first test, in contrast to a trial and error approach. As such, the alignment system <NUM> reduces installation and testing times, and improves disinfecting UV irradiance in relation to the target component.

As described herein, the alignment system <NUM> is configured to verify a desired alignment of an ultraviolet (UV) lamp with respect to a target component. The alignment system <NUM> includes the housing <NUM>. The UV sensor <NUM> is coupled to the housing <NUM>. The UV sensor <NUM> is configured to detect UV light emitted from one or more UV light sensors of the UV lamp and output one or more signals indicative of the UV light.

At <NUM>, the pointer <NUM> is extended to ensure alignment of the UV sensor <NUM> with the UV light emitter(s) of the UV lamp. At <NUM>, the UV recorder <NUM> is activated. The operator may then leave the space.

At <NUM>, the UV lamp is activated to emit UV light from the UV light emitter(s). At <NUM>, the UV sensor <NUM> detects the UV light, such as the intensity of the UV radiation. At <NUM>, the UV recorder <NUM> records signals (received from the UV sensor) indicative of the detected UV light. In at least one example, the UV sensor <NUM> detects the intensity of UV radiation and connects to the UV recorder <NUM> to output the electrical signal which varies with UV intensity. The UV recorder <NUM> stores data related to the detected UV light. The data can then be downloaded to a computing device, such as a laptop computer, a handheld smart device, a computer workstation, and/or the like. The operator may then analyze the data regarding the UV light stored in the recorder to validate the installation irradiance.

<FIG> illustrates a perspective front view of the alignment system <NUM> having a pointer <NUM> in an extended position, according to an example of the present disclosure. <FIG> illustrates a perspective front view of the alignment system <NUM> of <FIG> having the pointer <NUM> in a retracted position. As shown in <FIG>, in at least one example, the pointer <NUM> is a telescoping arm having a plurality of telescoping segments <NUM>.
