Abstract: A method for quantifying an exposure dose for a surface is disclosed. The method may include emitting one or more beams of 222 nm light onto a portion of the surface using one or more far ultraviolet (UV) light sources capable of emitting 222 nm light, the portion of the surface being coated with one or more fluorescent coatings. The method may include capturing images of the portion of the surface. The method may include adjusting one or more image characteristics for the captured images using one or more filtering methods. The method may include generating a histogram of the adjusted images based on the one or more filtering methods. The method may include determining a pixel surface area for the generated histogram. The method may include calculating the exposure dose for the surface based on the generated pixel surface area and a predetermined calibration curve.

Abstract: A self-disinfecting passenger control unit (PCU) includes a transparent or translucent molded or injected polycarbonate layer fused between inner and outer films, the outer film divided into contact surfaces (e.g., for passenger control of lights, call buttons, seats, and other functions) and the inner film including embedded traces. Within the molded polycarbonate layer are embedded LED units configured for continuous near-ultraviolet (near-UV) emission (e.g., at or near 405 nm), providing a uniform luminous output directed at the outer film and capable of antiviral/antibacterial irradiation of the high-touch contact surfaces of the outer film. As the continuous near-UV output is both visible by, and safe for, passengers, the LED units may double as backlighting for guiding passengers to the correct contact surface for adjusting a desired cabin function.

Abstract: A method of determining occupancy of an area is disclosed herein. The method includes receiving a first signal from an occupancy sensor, the first signal indicating a distance to a surface and an infrared signature of the area, determining a first infrared signature of the area based on the first signal from the occupancy sensor, receiving a second signal from the occupancy sensor, the second signal indicating the distance to a surface and the infrared signature of the area, determining a second infrared signature of the area based on the second signal, the second infrared signature being different than the first infrared signature, determining that the area is occupied based at least on part on the second infrared signature being different than the first infrared signature, and setting a status of the area to occupied in response to the second infrared signature being different than the first infrared signature.

Abstract: A of using an ultraviolet (UV) light emitter is disclosed herein. The method includes measuring, by a processor, a first distance from the UV light emitter to a target surface, activating, by the processor, the UV light emitter, and recording, by the processor, a second distance from the UV light emitter to the target surface. The method further includes calculating, by the processor, an accumulated dose of UV light on the target surface based at least in part on the second distance and deactivating, by the processor, the UV light emitter in response to the accumulated dose reaching a target dose.
