Energy self-sufficient radiofrequency transmitter

Abstract

The energy self-sufficient radiofrequency transmitter has at least one electromechanical transducer with a rectifier circuit connected downstream and with a voltage converter circuit. A logic circuit configuration is connected to the voltage converter circuit. The logic circuit configuration has a sequence controller a memory in which an identification code is stored. The energy self-sufficient radiofrequency transmitter also has a radiofrequency transmission stage that is connected to the logic circuit configuration and a transmission antenna.

       29 . A switching system, comprising:
 a power source for providing a voltage across first and second electrical terminals;   a regulator having an input side and an output side, said input side of said regulator being electrically connected to said first and second electrical terminals;   a radio frequency transmitter electrically connected to said output side of said regulator, said radio frequency transmitter comprising a programmable encoder circuit-programmed to generate one or more unique codes, said first radio frequency transmitter adapted to transmit the one or more unique codes;   a radio frequency receiver for receiving the one or more unique codes transmitted by the radio frequency transmitter, said radio frequency receiver being adapted to generate a switching signal in response to receipt of the one or more unique codes; and   a switch having a first position and a second position, said switch being in communication with said radio frequency receiver, said switch being adapted to change between said first position and said second position in response to said switching signal.
