Abstract:

The present invention discloses an automatic range containment system for e in an electric/optical or electromagnetic active "radar" type sensor to discriminate against background obstructions within a sensor field of view. The system comprises an intrusion timer initiated by a signal received from a target sensor; a containment interval timer initiated by a turn-on pulse; a transmitter oscillator in combination with a clock generating pulses; a range containment timer initiated by the pulses; a range set-back timer in combination with a range gate and a gate; a range counter for counting and totalling a signal passed through the gate; and a digital-to-analog converter converting the signal from the range counter to the range containment timer providing a range control causing the system to reduce operational range if the background obstructions appear within the sensor's field of view.

Abstract:

AC-DC voltage regulation is achieved utilizing, among other components, a series pass control element which is serially connected to a detector and filter output stage and between circuit input terminals and an output load. A rectified input voltage is applied to the series pass control element which controls the required amount of current flowing into a load every 1/2 cycle of the input signal. This current is, in turn, detected and filtered to provide the regulated DC output voltage. A voltage sensor is connected to the output of the series pass control element and in parallel with the detector and filter stage; this sensor breaks down at a predetermined level of series pass voltage to, in turn, generate a feedback control voltage. This control voltage is fed back to a current controlled switch which is connected in shunt with the series pass control element. This current controlled switch responds to the feedback voltage to accordingly limit the current conduction in the series pass control element to precisely the amount required by a varying load connected to the circuit output terminal.
