VEHICLE ANTITHEFT DEVICE Russian patent published in 2005 - IPC

Abstract RU 2254245 C1

FIELD: transport engineering.

SUBSTANCE: invention relates to facilities designed for preventing unauthorized use and hi-jacking of vehicles. Transmitter is installed on check station, and receiver, actuating unit and passive receiver-responder are mounted on vehicle. Transmitter contains master oscillator, modulating code generator, phase keyer, power amplifier, receive-transmit antenna, high-frequency amplifier, duplexer, phase detector and computer. Receiver contains receiving antenna, high-frequency amplified, two spectrum width meters, frequency doubler, comparator unit, two threshold units, key, ratio-of-two frequency divider, narrow-band filter, phase detector, single-pole valve and store. Actuating unit contains key, ignition coil, two relays, switch, ignition switch, storage battery, side lamps, sound alarm, control switch, three capacitors, thyristor, two resistors, voltage stabilizing diode. Receiver-responder contains piezocrystal, microstrip antenna, electrodes, buses and reflecting plates.

EFFECT: enlarged functional capabilities, possibility of finding hi-jacked vehicle in static deenergized state at parking place, in garage or street.
