Locking apparatus

Abstract

An electronic control actuating system having signal transmitting or injector means and signal receiving means. The signal transmitting means includes a plurality of self-contained oscillator circuits, each oscillator circuit capable of producing an independent radio frequency output signal and wherein the oscillating circuits are adapted to be selectively positioned relative to an actuator means capable of sequentially supplying energy to each of the oscillator circuits for effecting an output of a plurality of sequentially transmitted coded signals. The signal receiving means includes a plurality of self-contained filter circuits, each filter circuit designed for receiving one of the coded radio frequency signals produced by the signal transmitting means, with the signal receiving means including a plurality of sequentially operable switching means, and wherein the filter circuits are adapted to be selectively positioned relative to the sequentially operable switching means for effecting a sequential operation of the switching means to produce an output actuator signal in response to a complete reception of the coded signals produced by the signal transmitting means. Should any signal be received out of sequence, there will be no output signal to the actuator (unlocking-locking unit). .Iadd.
