Abstract
Abstract A control receiver for selective evaluation of pulse images characterizing remote control commands. The receiver embodies a bistable switching element shifted no later than at the beginning of a received pulse image into a predetermined second condition of two possible conditions thereof, a switching mechanism associated with the aforementioned bistable switching element compares the received pulse image with at least one pulse image associated with the receiver. The bistable switching element returns to its first condition upon non-coincidence of the received and associated pulse image, whereas upon coincidence thereof and until the end of the pulse image this switching element retains its second condition, and upon interrogation causes the performance of a command. Now, according to important aspects of the present invention the aforementioned switching mechanism embodies a stepping switch, each respective switching position thereof being associated with a respective time interval of the pulse image associated with the central control receiver. Furthermore, the switching mechanism additionally possesses a command coding mechanism coupled with the outputs of the aforementioned stepping switch and with at least one current supply network of the bistable switching element. The conductor arrangement at the command coding mechanism for each of the switching positions, depending upon whether the time interval associated with each such switching position of the pulse image associated with the central control receiver exhibits a pulse interval or a pulse, connects the corresponding output of the stepping switch with a first or second current supply network, whereas on the other hand, no such connection is established if the interval associated with the respective switching position is an interval which is not to be monitored. Additionally, the inventive equipment is manifested by the further features that, by means of the aforementioned switching mechanism and the aforementioned connections only upon non-coincidence of the pulse images which are compared with one another is there present a shunt to the bistable switching element, by means of which there can be removed from the bistable switching element the energy supply required for maintaining its second switching condition or state.
