Abstract:
1. A system, comprising; a sender having a first value of a configuration parameter and comprising; a signal generator; an amplifier coupled to the signal generator, said amplifier configured to receive power from a power source and to generate an electrical transmission signal adapted to be used to generate ultrasonic waves; a sender transducer coupled to the amplifier, the sender transducer adapted and configured to generate ultrasonic waves having a first phase based on the electrical transmission signal received from the amplifier, the first phase based on the first value of the configuration parameter; a sender communications device adapted to receive input from a receiver communication device, the input including a second value of the configuration parameter; a sender controller coupled to at least one of the signal generator, the amplifier and the sender transducer, the sender controller adapted to change the first phase to a second phase based on the received second value for the configuration parameter, the sender controller causing the sender to send ultrasonic energy having a first phase to a receiver based on the first value of the configuration parameter, the ultrasonic energy having, the first phase being converted into electrical energy at a first efficiency, and to send ultrasonic energy having the second phase to a receiver based on the second value of the configuration parameter, the ultrasonic energy having the second phase being converted into electrical energy at a second efficiency, wherein the second efficiency is different than the first efficiency; and the receiver comprising:
