Claim Text:
1. A method of acoustical transmission of at least one of power, instructions, and data through an acoustic-electric channel using piezoelectric transducer arrays, the method comprising: providing a channel medium for passing acoustical transmissions, the channel medium comprising a first surface and a second surface, the channel medium being capable of transmitting acoustical energy there through; providing a send arrangement coupled to the first surface and a receive arrangement coupled to the second surface, and wherein the send and receive arrangements are positioned at least partially on opposite sides of the same region of the channel medium; wherein the send arrangement comprises a send array which is coupled to the first surface; wherein the send array comprises a plurality of send elements, and wherein each send element comprises a transducer and can be controlled independently of other send elements in the same array; wherein the receive arrangement comprises at least one receive transducer which may optionally be an element within a receive array; optimizing at least the send array, wherein the optimization process comprises: sending a plurality of transmissions using different combinations of send elements while maintaining the same transmission power, detecting the plurality of transmissions sent by the different combinations of send elements using the at least one receive transducer of the receive arrangement, determining which of the tested combinations of send elements resulted in the strongest received transmission being received at the receive arrangement, activating the send elements in the combination which resulted in the strongest received transmission, and deactivating the remaining elements of the send array; after the array has been optimized, sending transmissions from the send arrangement using the activated elements of the send array, and receiving said transmissions using the at least on receive transducer.
