  • Proximity sensor apparatus
    Patent number: 4871997
    Abstract: A radio frequency proximity sensing apparatus includes a transmitter having an oscillator circuit for propagating a pulsed RF signal and a receiver having a sensor circuit for the detection of the propagated pulsed RF signal. The receiver includes a logic circuit for processing the propagated pulsed RF signal and a plurality of 14-bit oscillator/resistor timers. An alarm in the receiver is controlled by first and second oscillating circuits such that the transmitter and receiver act in unison to actuate the alarm as the receiver and the transmitter are separated by a distance exceeding the effective RF signal range of the transmitter.
