Abstract: A method of adjusting the sensitivity of stabilizing an optronic fuse system, which includes a controller, and, as a receiver, an avalanche photodiode (APD). In order to avoid adjustment of an analog electronic system with potentiometers, laser trimming or individual resistor fitment, the controller ascertains the temperature of the APD in such a way that the sensitivity of the APD corresponds to its reference sensitivity at any temperature.

Abstract: During a robot is taking workpieces out of a workpiece container 2, a safety fence 2 and a photoelectric sensor 1 are valid and the robot is stopped when the safety fence 2 is opened or a beam from the photoelectric sensor 1 is cut off. A safety fence 1 and a photoelectric sensor 2 are invalid and do not hinder operation of the robot. Operation feasible state indicating lamps of workpiece feeding lamp/switch boxes 1 and 2 are turned on and off, respectively. If an operator replaces a workpiece container 1, he/she actuates an operating area entrance switch or the box 1 into an ON state to make OFF state an operation feasible signal for the robot RB on a side of the workpiece container 1. When the robot is operating on the side of the workpiece container 1, the robot can continue to operate while similarly ensuring safety of the operator.

Abstract: A DC offset cancellation circuit that is capable of canceling a DC offset voltage occurring between a pair of differential output signals of a differential amplification circuit, while preventing a signal waveform from being distorted due to accumulation of AC components and a photo-electric pulse conversion circuit that is capable of generating an electrical pulse signal that accurately reproduces a rise timing and a fall timing of an optical pulse signal by canceling the DC offset voltage are provided.

Abstract: The present invention is directed to a photoconductive switch module. The photoconductive switch module comprises a first substrate having light-emitting elements, and a second substrate having photoconductive switch elements, whose number is equal to that of the light-emitting elements. The light-emitting elements face the photoconductive switch elements, so that the photoconductive switch elements are turned on/off in accordance with lighting/extinction of the light-emitting elements. The photoconductive switch module further comprises a third substrate arranged between the first substrate and the second substrate. The third substrate has through holes, whose number is equal to that of the light-emitting elements. Each through hole is positioned between a light-emitting element and a photoconductive switch element facing each other. Drive light emitted from each light-emitting element travels to the photoconductive switch element via the through hole.

Abstract: An optical signal detection apparatus and method for a computer mouse compares two output signals of a first photo-transistor and a second photo-transistor to obtain a reference signal. Then a pulse signal generating unit utilizes the reference signal to generate a series of pulse signals each occurring when the voltage level of the reference signal is changed. Thereafter a sample and hold circuit samples and holds the voltage value of the output signals of the photo-transistors at the moments that pulse signals are generated. A dynamic reference voltage generating unit uses the sampled voltage values to calculate a dynamic reference voltage. The voltage level of the dynamic reference voltage is varied with the output signals of the photo-transistors. By using the dynamic reference voltage to compare with the output signals of the photo-transistors, the on/off statuses of the photo-transistors can be precisely detected.
