Remote control apparatus
First Claim
1. Apparatus for remotely controlling automatic apparatus by means of a user operated transmitter comprising:
- (a) means for controlling the frequency of the transmitter;
(b) a receiver for receiving signals from the transmitter within a predetermined frequency range;
(c) means at the receiver for detecting receipt of a signal within the predetermined range and for transmitting back to the transmitter a signal indicating such receipt;
(d) means at the receiver for detecting the duration of a signal received within the predetermined frequency range and for indicating when such a signal has been continuously so received for a predetermined period, and(e) means at the receiver responsive to signals detected as defined in (c) and (d) for energizing controls,whereby the user adjusts the frequency to come within the receiver'"'"'s range, the receiver informs the user when the frequency is correct, thereafter the user holds the signal for the predetermined duration and the receiver informs him when he has succeeded in so doing.

Abstract
A remote control device adapted to operate on a single remotely transmitted standardized command signal of a specific duration having a frequency within a predetermined frequency band, to actuate one or more control functions at the receiver, the receiver being equipped separately to indicate (a) when a signal within the correct frequency band is being received, and (b) when such a signal has been received for the specific duration. Means are provided at the receiver for changing the available command options automatically and so indicating to the transmitter, and for temporarily halting the command option changer upon the reception of a signal within the predetermined frequency range. Additional means are provided at the receiver for a series of command signals to be accepted by the receiver in such a way that the command option changer does not sequence to the next command option until the series of command signals is completed. Further means are provided to minimize interference from ambient sounds whereby the receiver will reject a predetermined number of standardized command signals, and provide an indication of that number.
