Abstract:

A system for transmitting power and data through a solid medium includes a power signal transmitter configured to acoustically transmit power through the solid medium to a power signal receiver using a first frequency and a data signal transmitter configured to acoustically transmit data through the solid medium to a data signal receiver using a second frequency. The second frequency may be offset from the first frequency and from at least a first overtone of the first frequency. Furthermore, the data signal transmitter and data signal receiver may be positioned at a null of a pattern of acoustic waves produced by operation of the power signal transmitter. The system may further include a notch filter coupled to receive an electrical output of the data signal receiver, the notch filter being tuned to attenuate the first frequency.
