Abstract
Abstract The disclosure includes a radio-controlled garage door operator, operated from a pulsed latch relay connected to be energized by a pushbutton switch or contacts of a pulsed relay of a radio control receiver unit. The latter includes a superregenerative, self-quenching oscillator receiver connected to a channel selection and demodulating circuit. The selection circuit includes a paralleled resistor and capacitor in series with a diode to pass the desired door-operating frequency signal and actuate an electronic switch. A bypass circuit includes a parallel capacitor and adjustable inductor in series with an attenuating circuit including a paralleled resistor and capacitor. The inductor-capacitor resonates at the door-operating frequency. The output circuit includes a pair of complementing normally off transistors interconnected by a timing and disconnect capacitor. The first transistor is driven on and provides a turn on bias path for the second transistor including the capacitor to momentarily actuate the latch relay. The capacitor is maintained charged through an alternate path which when the first transistor turns off provides a rapid discharge capacitor path. The receiver circuit is connected to the power supply through the same contacts connected to actuate the relay and thereby provides a two-wire control connection.
