APPARATUS FOR POWER WIRELESS TRANSFER BETWEEN TWO DEVICES AND SIMULTANEOUS DATA TRANSFER
First Claim
1. A system for wirelessly transferring power, comprising:
- a first device configured to be coupled to a power supply source and including a first resonant circuit configured to resonate at a first frequency corresponding to a wavelength; and
a second device that includes a battery and a second resonant circuit configured to resonate at said first frequency, the first and second resonant circuits being spaced apart by a distance smaller than the wavelength corresponding to said first frequency, said first device being configured to wirelessly transfer to said second device a first signal having a power configured to charge said battery, wherein;
said first device comprises;
a first modulator configured to modulate the frequency of said first signal for transferring data from said first device to said second device simultaneously with the power transfer; and
a first demodulator configured to demodulate a second signal from said second device; and
said second device is configured to transmit the second signal to the first device and comprises;
a second modulator configured to modulate a frequency of the second signal; and
a second demodulator configured to demodulate the first signal sent from said first device, to obtain the transmitted data, wherein the first and second devices are configured to provide full-duplex communication using the first and second modulators and first and second demodulators.

Abstract
A system for the wireless transfer of power includes a first device connected to a power supply source and provided with a first resonant circuit at a first frequency, a second device comprising at least one battery, provided with a second resonant circuit at said first frequency, arranged at a distance smaller than the wavelength associated with said first frequency and not provided with wires for the electrical connection with said first device. The first device is adapted to transfer a first signal representing the power to be sent to the second device for charging said at least one battery and comprises means adapted to modulate the frequency of said first signal for transferring data from the first device to the second device simultaneously with the power transfer. The second device comprises means adapted to demodulate the received signal, corresponding to the first signal sent from the first device, to obtain the transmitted data.
