Remote control receiver
First Claim
1. Apparatus for receiving remote control signals having an alternating sequence of two chronologically successive frequency pulses, the first said pulse having a first predetermined frequency and the second said pulse having a second frequency manually selected from a predetermined number of frequencies, each of said predetermined number of frequencies representing a respective command to be carried out, the apparatus comprising:
- means for detecting said remote control signal;
means coupled to the output of said detecting means for selectively amplifying said remote control signal;
means coupled to the output of said amplifying means for decoding said remote control signal into a group signal dependent on said first frequency and a command signal dependent on said second frequency;
controllable means for gating said command signal from said decoding means to command-signal registering means;
means for registering the command signal from said decoding means, said registering means having a command-signal input and a command-signal output for each of the predetermined number of commands and a blocking input for each command-signal output;
means coupled to each said command-signal output for implementing the corresponding command;
circuit means responsive to said group signal and coupled for controlling said gate means to allow passage of said command signal to said command-signal registering means; and
circuit means responsive to receipt of a command signal at one of said command-signal inputs for locking the remaining command-signal inputs by supplying a signal to the corresponding blocking inputs.

Abstract
Apparatus for receiving remote control signals which comprise an alternat sequence of two chronologically successive pulses, the first pulse having a first predetermined frequency and the second pulse having a second frequency manually selected from a predetermined number of frequencies, each of the predetermined number of frequencies representing a command to be carried out. The receiver comprises a signal detector, a signal amplifier and a circuit for decoding the remote control signal into a group signal dependent on the first frequency and a command signal dependent on the second frequency. A controllable gate is provided for gating the command signal from the decoding circuit to a command signal register having a command signal input for each of the commands, and an input for blocking each command signal output. Means coupled to the command signal outputs implement the commands. A circuit responsive to the group signal controls the gate, while a circuit responsive to receipt of a command signal in the register causes the remaining command signal inputs to be locked.
