Fiber optic safety system
11079066 · 2021-08-03 ·

Safety systems for operating equipment have a source of visible light, a first signal light transmitter, a first signal light receiver, preferably a second signal light transmitter and second signal light receiver. A fiber optic bundle with at least one section of illuminated cable emits the visible light and carries the signal light. The signal light follows an optical circuit through the fiber optic bundle from the signal light transmitters to the signal light receivers. The signal light receivers are connected to suitable controls of the system such that if a predetermined light signal is not received by the signal light receiver(s), the operating equipment will stop and/or alarms will be generated. The fiber optic bundle is connected to optical pull switches which interrupt the light circuit if a person applies a predetermined pull force to the optical fiber bundle.
