    Abstract: An optical output shutoff detecting circuit of the present invention includes a flip-flop. The flip-flop has a D terminal to which a signal representative of a result of comparison between the output level of an optical signal output from a laser diode and a reference signal is input, and a C terminal to which a signal produced by delaying a data signal is input. The output signal of the flip-flop is used to detect the output level of the optical signal.

    Abstract: A system (300) for gating a sensor (118) includes a detector (120) that detects light and outputs a signal (102) corresponding to the light. A control unit (334) receives the signal (106), and enables and disables a power supply (314) in response to the signal (106) to generate a gated power signal (316). The power supply (314) outputs the gated power signal (316) to a sensor (118) sensing the light.
