US 4,052,700 A · Remote control receiver

Abstract

A remote control receiver for producing different control signals in response to operating signals of respectively different frequencies. The receiver includes operating signal frequency counter which counts operating frequency oscillations in repeated counting cycles and produces an output signal when a predetermined count has been reached. The output signal controls a reference frequency counter which counts the number of reference frequency oscillations in each counting cycle. The count of the reference frequency counter reached during each counting cycle is stored and at the end of each counting cycle, a comparator compares the current count of the reference frequency counter with the stored count. The comparator produces a signal indicating agreement or non-agreement of the compared counts. An error register accepts every comparison result and passes a control signal to the receiver output associated with the particular operating signal being received, only when a predetermined number of agreements has been reached.

Dependent claims

A remote control receiver for the reception of command signals of different operating frequencies in individual channels, said receiver having a plurality of control outputs, each output assigned to an individual one of said channels, comprising operating frequency counter means for counting in each cycle of a repetitive sequence of counting cycles, received operating frequency command signals for production of an output signal upon the attainment of a predetermined count;

reference frequency counter means controllable by the output signal of said operating frequency counter means for counting reference frequency signals in each said counting cycle of the operating frequency counter means;
storage means for storing a reference frequency counter count reached in a said counting cycle;
comparator circuit means for comparing after each counting cycle the reference frequency counter count with the count stored by said storage means and for producing, as a result of said comparison, a signal indicating agreement or non-agreement of said compared counts;
and error register means for receiving and storing said signals produced by said comparator means to produce, upon the attainment of a predetermined number of consecutive agreements, an enabling signal for the generation of a control signal at the said control output assigned to the received operating frequency.
