DEVICE TO DETECT PEOPLE UNDER RUBBLE, EXPLOSIVES AND DRUGS Russian patent published in 2011 - IPC G01S1/02 

FIELD: physics.

SUBSTANCE: proposed device comprises dog collar, mobile primary transducer and secondary transducer. Primary transducer comprises piezo element tactile sensors (4.1, 4.2), switch (5), amplifier (6), modulator (7), radio transmitter (8), power supply (9), light and audio beacons (10, 11). Modulator (7) comprises trigger (17), master oscillator (18), phase manipulator (19), unipolar gate (20), integrator (21), first threshold unit (22), and first key (23). Radio transmitter (8) comprises power amplifier (24) and antenna (25). Secondary transducer comprises radio signal receiver, demodulator, second key, registrator, vibration and frame antennas, HF amplifiers, amplitude detectors, division unit, second threshold unit, multipliers, narrow-band filter and low-frequency filter. Tactile detectors are secured on animal body at maximum pulse points. Switch, amplifier, modulator, radio transmitter, power supply, light and audio beacons are arranged on dog collar. Secondary transducer is located at control post.

EFFECT: higher validity of results.
