摘要: A device for the bi-directional transmission of data between a master system and slave uses single antenna reception each tuned to same frequency; comprises first circuits transmitting by modulating an electromagnetic signal at detection detecting, during signal, variations in electrical characteristics induced modulation impedance as function second be transmitted from system; restoring on basis detected variations; connected data; rectifier circuit across rectifying signal; power supply powering loads with DC voltage energy rectified switching series modulate real part high value low when is driven its opened closed position control representative data.
