ELECTRONIC LOCK Russian patent published in 2004 - IPC

Abstract RU 2236527 C1

FIELD: protection of different objects against unauthorized access.

SUBSTANCE: electronic lock includes turning-on members, for example in the form of mechanical lock with electric contact; actuating mechanism; first radio transmitter, radio receiver; unit for coding; inductance members and unit for frequency conversion. Lock is provided with second radio transmitter connected with power switch-off. Unit for frequency conversion is in the form of non-linear member. Radio receivers are tuned for frequencies W1 - ΔW and W1 + ΔW. Receiving oscillation circuit is tuned for frequency W₁. Outlet oscillation circuit and radio receiver are tuned for frequency 2W₁. Passing band ΔW_p of radio receiver is less than 4ΔW.

EFFECT: enhanced operational reliability of lock due to elimination of false operation caused by parasitic harmonic components of spectrum of signal irradiated by radio transmitter and received by radio receiver when there is no coding unit near lock.
