Abstract:
1. A sanitizing system for use with an elevator, the system comprising: a first sensor to detect the absence of humans within the elevator and to transmit a first input signal when humans are absent; a second sensor to detect the position of at least one door of the elevator and to transmit a second input signal when the door is closed; a germicidal ultraviolet light source to provide electromagnetic radiation in the ultraviolet range and to receive a first output signal to activate the ultraviolet light source; a motor to move the ultraviolet light source and to receive a second output signal to move the ultraviolet light source from an inactive position to an active position; and a controller to receive the first input signal and the second input signal, and to transmit the first output signal and the second output signal, wherein the controller transmits the first output signal and the second output signal when the controller receives the first input signal and the second input signal.
