Claim Text:
1. An apparatus comprising: an ultraviolet transparent screen, wherein an external surface of the ultraviolet transparent screen is accessible to a user of the apparatus; a cover configured to cover the ultraviolet transparent screen, wherein an internal surface of the cover facing the external surface of the ultraviolet transparent screen is reflective, wherein the cover includes a plurality of fins extending therefrom, with each fin separated from an adjacent fin by a predetermined spacing, wherein each of the fins contacts a separate portion of the external surface of the ultraviolet transparent screen in response to the cover being in a closed position, such that a layer of air is located between the cover and the ultraviolet transparent screen in each spacing formed between adjacent fins; a set of ultraviolet radiation sources having a location that includes at least one of: within an internal portion of the ultraviolet transparent screen near a side edge thereof or in a vertical orientation contacting one of an internal surface of the ultraviolet transparent screen or the external surface thereof, the set of ultraviolet radiation sources configured to generate ultraviolet radiation directed towards the external surface of the ultraviolet transparent screen; a diffusively reflective layer disposed between the ultraviolet transparent screen and the cover, wherein each of the fins contacts a separate portion of the diffusively reflective layer in response to the cover being in a closed position, such that a layer of air is located between the cover and the diffusively reflective layer in each spacing formed between adjacent fins, wherein the diffusively reflective layer is configured to diffusively reflect radiation emitted from the set of ultraviolet radiation sources back throughout the ultraviolet transparent screen and to partially transmit the emitted radiation towards the cover, wherein the partially transmitted radiation is directed towards at least one of the spacings, the partially transmitted radiation being reflected from an interface with the at least one of the spacings through the diffusively reflective layer to the ultraviolet transparent screen for disinfection thereof; and a monitoring and control system located in an internal portion of the apparatus for managing the ultraviolet radiation by performing a method comprising:
