A communication system comprising a transmitter for radiating a carrier frequency signal, which may be modulated, to a data station. The station includes a rectifier for rectifying the received carrier signal to provide energy to the station elements. A data source at the station produces a data signal representative of the information to be transmitted. A harmonic generator produces harmonics of the carrier signal and the harmonic signal is modulated with the data or information signal. An antenna radiates the modulated harmonic signal to a receiver which demodulates the received signal to extract the information therefrom. Thus, a completely self-contained and economic system is provided, since the carrier signal per se supplies the energy to operate the data station. Additionally, the communication system may include a carrier signal having an address encoded therein and the station may comprise an address decoder so that only a selected addressed station will transmit the desired data at any one time.
A communication system comprising transmitting means for transmitting a signal having a preselected frequency;
A method for transmitting information to a remote station having no source of energy therein comprising transmitting a signal having a preselected frequency to the remote station, detecting said preselected frequency signal at said remote station and producing a power signal from the detected signal by applying the preselected frequency signal to only a first two-terminal diode network comprising only semiconductor diode means polarized in only one direction, energizing an information signal generator with said power signal to generate an information signal, producing a harmonic signal from said transmitted signal by applying said transmitted signal to only a second two-terminal diode network comprising only semiconductor diode means polarized in only one direction, and modulating said harmonic signal with said information signal by applying said information signal to said second diode network.
A communication system comprising a transmitter having carrier signal generating means for generating a carrier signal having a preselected frequency, transmitter modulating means for modulating said carrier signal with a modulation signal, said modulation signal comprising reference and clock signal portions, and radiating means for radiating said modulated carrier signal;
