Abstract: A system for remote powering at least one sensor or actuator from a RF power source including a flexible waveguide having a flexible dielectric layer and at least one flexible conductive layer connected to the flexible dielectric layer. The at least one sensor or actuator is arranged to be coupled to the flexible waveguide and the RF power source is arranged to be wirelessly coupled to the flexible waveguide and to generate RF power. The flexible waveguide guides the propagation of the RF power from the RF power source to the sensor or actuator in order to wirelessly power the sensor or actuator.

Abstract: Useful information taking the form of an analog or digital voltage is communicated between a transmitter and a receiver using UWB signals. The transmitter includes a subcarrier modulator, a high frequency oscillator and a transmission antenna and the receiver includes a reception antenna and an amplifier and a demodulator for discriminating the useful information in a signal received at the reception antenna. On transmission, the method generates a narrow frequency band high frequency carrier, modulates the high frequency carrier using a subcarrier with a modulation index at least equal to 10, and modulates the subcarrier using the useful information. On reception, the method demodulates the carrier to extract therefrom the subcarrier and demodulates the subcarrier to extract therefrom the useful information.

Abstract: Useful information is transmitted by means of a UWB signal from a sender comprising a UWB signal modulator and a send antenna to a receiver comprising a receive antenna and detection and demodulation means for discriminating the useful information in the signal received at the receive antenna. In the receiver, the signal received at the receive antenna is compared to a first power threshold value and transmission of the received signal to the detection/demodulation means is blocked if the power level of the received signal exceeds the first threshold value.
