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.

Abstract: An object detection system for use in detecting the presence of an object within a space, such as in an aisle of a mobile storage system bounded by at least one mobile storage unit, includes a pair of pivotable light emitter/receiver unit located outwardly of each side of the space and a series of reflectors located outwardly of each side of the space. Each emitter/receiver unit includes a pivotable emitter which emits a beam of light which passes across and through the space and impinges upon the reflectors located outwardly of the opposite side of the space. A receiver associated with each emitter/receiver unit receives reflected light from the reflectors. The presence of an object within the space prevents the light beam from reaching one or more of the reflectors, and the absence of one or more reflected light beams is detected such that operation of the mobile storage unit is prevented until the object exits or is removed from the space.

Abstract: A variable resistance circuit comprises a resistance circuit including a plurality of resistors serially connected, and a bypass circuit connected in parallel with the resistance circuit for bypassing one or more resistors selected from the plurality of resistors. The bypass circuit includes a plurality of transistors selectively turned on or off. The variable resistance value is determined by a combined resistance value of a parasitic resistance of one or more transistors being turned on and one or more resistors being bypassed as well as a combined resistance value of one or more resistors being not bypassed. The gate widths of the plurality of transistors are so set that the variable resistance value varies approximately in steps of a predetermined value. Various resistance values can be set in high precision by selectively turning on or off the plurality of transistors.

Abstract: An object detection system employs a photo-emitter and photo-detector for synchronously detecting and processing an optical signal reflected from an object in a pinch zone of a window or door opening. A photo-emitter light signal is modulated by a modulation signal having an active phase and an inactive phase. The optical detector provides an optical detector signal that is a function of the intensity of the received light. The detected light signal is synchronously detected using a switching amplifier that multiplies the reflected modulated light signal by a first gain during the active phase and by a second gain during the inactive phase. The duration of the active and inactive phases and the first and second gains are selected such that the system gain will average to zero for ambient light when integrated over a predetermined measurement period. The synchronously detected signal is subtracted from a predetermined offset voltage, and this difference is then integrated over the measurement period. The output of the integrator is then compared to a predetermined threshold value.
