Abstract: Systems are disclosed which include processor-executable program instructions for receiving data regarding characteristics of a room in which one or more disinfection sources are arranged and determining, based on the received data, individual operating parameter/s for the one or more disinfection sources. Other systems are provided which include processor-executable program instructions for discerning, for each of a plurality of disinfection sources, a target location, region, object or surface within a room in which the disinfection sources are arranged. The systems further include program instructions for comparing the target locations/regions/objects/surfaces and executing corrective actions upon detecting two or more locations/objects/surfaces are within a predetermined distance of each other and/or upon detecting two or more regions overlap.

Abstract: The attenuator includes an externally threaded sleeve for receiving standard ferrules within its bore at opposite ends, an internally threaded adjuster for threaded engagement about the sleeve and a ferrule locking nut threadedly engageable about the adjuster for clamping a ferrule at one end of the sleeve between the adjuster and ferrule locking nut. By relatively threading the sleeve and adjuster, the ferrule may be displaced relative to the sleeve whereby the end face of the optical fiber carried thereby is adjustably spaced from the end face of an optical fiber carried by a ferrule fixed on the sleeve at the opposite end thereof.
