DEVICE OF WARNING SIGNAL SYSTEM FOR DETECTION OF INTRUSION INTO GUARDED ROOM Russian patent published in 1996 - IPC

Abstract RU 2069013 C1

FIELD: signalization devices. SUBSTANCE: device of warning signal system is related to equipment warning about burglary. Device incorporates superregenerator used in the capacity of transceiver, digital frequency-phase detector, controlled low-frequency generator and digital phase integrator. Signal from output of digital phase integrator controls operations of alarm signal former. EFFECT: design of device of warning signal system capable of high sensitivity for detection of slowly moving objects with low-level inherent radiation. 1 dwg
