Abstract: A concealed air sanitization device is disclosed. The concealed air sanitization device comprises a housing having an interior chamber, and an air inlet and outlet communicating between the interior chamber and an exterior environment. The concealed air sanitization device further comprises an air circulation unit configured to draw air into the interior chamber through the air inlet, one or more ultraviolet light sources disposed within the interior chamber, and one or more sensors configured to detect human presence proximate the air sanitization device. The concealed air sanitization device further comprises a processor configured to receive signals from the sensors in response to detection of human presence, and activate the air circulation unit and ultraviolet light sources in response to the detection to draw air from the exterior environment into the interior chamber and emit ultraviolet light to the air.

Abstract: A portable ultraviolet sanitization device is disclosed that includes a gripping portion, an ultraviolet electromagnetic radiation emitter portion, and a power source. The ultraviolet electromagnetic radiation emitter portion is disposed at a distal end of the gripping portion. The ultraviolet electromagnetic radiation emitter portion includes one or more ultraviolet light sources, such as light emitting diodes or excimer lamps. The power source is in electrical connection with the one or more ultraviolet light sources. The sanitization device is used to sanitize surfaces by eliminating viruses and other microorganisms. The sanitization device is particularly well-equipped to sanitize surfaces that are used intermittently, such as airplane cabins, restaurant seating areas, or similarly occupied spaces.

Abstract: A wavelength converting bandage including a substrate with an external surface and an internal surface. The wavelength converting bandage includes a plurality of quantum dots, each quantum dot individually sized to emit light within a wavelength range of 613 nm to 846 nm, defined as converted light. The wavelength converting bandage includes at least a portion of the substrate constructed to adhere to skin. The substrate may receive ambient light from the environment on the external surface and may emit converted light toward the skin.

Abstract: A method is for dynamically adjusting a circadian rhythm of an observer via a user device that includes control circuitry and an associated memory. The method includes determining a preconditioning schedule for at least one future event. Determining the schedule includes determining a preconditioning schedule for the at least one future events, including identifying a circadian shift needed, to the circadian rhythm of the observer, for the at least one future event, determining a timeframe for preconditioning, determining a per-day shift needed based upon the identified circadian shift needed and the determined timeframe, and determining if the needed per-day shift exceeds a threshold. Upon a determination that the per-day shift exceeds the threshold, the method includes setting the preconditioning schedule responsive to the determination to operate a light source to emit light based upon the preconditioning schedule.
