Ultrasound transdermal communication system and method

A method of providing a communication system, comprising the steps of:

• providing a first communication device configured to be implanted in an enclosure with a medium capable of transmitting communication signals;
• providing a second communication device configured to be located outside the enclosure;
• providing a second transmitter, coupled to the second communication device, and configured to transmit a first carrier signal into the enclosure during communication from the first communication device to the second communication device;
• providing a first receiver, coupled to the first communication device, and configured to receive the first carrier signal;
• providing a first power generator, coupled to the first receiver, and configured to generate a power supply derived from the first carrier signal;
• providing a first transmitter, coupled to the power supply, and configured to generate a second carrier signal from the power supply;
• providing a first modulator, coupled to the first transmitter, and configured to modulate the second carrier signal with information to be transmitted from the first communication device to the second communication device;
• providing a second receiver, coupled to the second communication device, and configured to receive the modulated second carrier signal;
• and
• providing a second demodulator, coupled to the second communication device, and configured to demodulate the second carrier signal,
• the first receiver and the second transmitter configured to form a mechanically tuned circuit having a value of Q during transmission of information signals of a first logical state and a second Q value during transmission of second information signals of a second logical state during communication from the second communication device to the first communication device,
• the second receiver and the first transmitter further configured to form the mechanically tuned circuit having the first value of Q during transmission of information signals of the first logical state and the second Q value during transmission of second information signals of the second logical state during communication from the first communication device to the second communication device,
• whereby the information signals are communicated from the first communication device to the second communication device, or vice versa, by way of mechanical vibrations through the enclosure.
