Abstract
Systems, methods, and apparatus for a detector and reflector for automation cell safety and identification are disclosed. In one or more embodiments, a method for machinery safety comprises transmitting, by an active transponder, at least one interrogation signal. The method further comprises receiving, by at least one passive transponder located on a user or on an item, the interrogation signal(s). Also, the method comprises generating, by a non-linear device of the passive transponder(s) in response to the interrogation signal(s), at least one response signal. In addition, the method comprises receiving, by the active transponder, the response signal(s). Additionally, the method comprises determining, by at least one processor, a location of the passive transponder(s) based on the response signal(s). Further, the method comprises determining, by the processor(s), whether the passive transponder(s) is located within a threshold distance away from machinery by using the location of the passive transponder(s).
