Apparatus for power wireless transfer between two devices and simultaneous data transfer

摘要

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.

主权项

1. An apparatus, comprising:
a battery; a first resonant circuit configured to resonate at a first frequency, the first resonant circuit including a first coil and being configured to wirelessly receive a first signal having a power configured to charge said battery and including data; a second resonant circuit configured to resonate at a second frequency, the second resonant circuit including a second coil and being configured to wireless transmit a second signal; a demodulator configured to demodulate the first signal to obtain the data of the first signal and charge the battery with the power of the first signal; and a modulator configured to modulate the second frequency of said second signal for transferring data externally, wherein the first and second resonant circuits, the demodulator, and the modulator are configured to provide full-duplex communication with external devices.
