Abstract: A handheld disinfection device includes a housing, an electromagnetic radiation source, a sensor, and a controller. The housing is configured to be grasped by an operator and the electromagnetic radiation source is affixed to the housing and is configured to operably emit disinfecting electromagnetic radiation. The sensor and the controller are coupled to the housing, and the controller includes a processor and a memory having instructions stored thereon that cause the processor to perform various operations. The various operations may include receiving, by the processor, operational data from the sensor pertaining to an operator's manipulation of the handheld disinfection device during a disinfecting treatment.

Abstract: A light assembly includes a base, an annular reflector, and a retainer. The base includes one or more light sources mounted thereto. The annular reflector comprises a first radially outward surface and a first radially inward surface. The annular reflector also defines a central longitudinal axis, with the first radially outward surface including a reflective surface. The retainer is coupled to the base and comprises a second radially outward surface. The second radially outward surface of the retainer seats against the first radially inward surface of the annular reflector to retain the annular reflector in a desired position relative to the light source mounted to the base, according to various embodiments.

Abstract: An end of life detection system for an anti-collision light may comprise a reflector and a plurality of LEDs located around an exterior of the reflector. A trend LED and reference LED may be located in an interior of the reflector. The trend LED may be powered on with plurality of LEDs. The reference LED may be powered on during an initial power-on self-check and turned off after completion of the initial power-on self-check.
