1. A system, comprising:

  • a sender 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; and

    a sender controller coupled to at least one of the signal generator, the amplifier and the sender transducer and adapted to change the first phase to a second phase based on at least one received configuration parameter; and

    a receiver comprising;

    a receiver transducer adapted and configured to receive ultrasonic waves generated by the sender transducer and to generate a receiver electrical signal based on the received ultrasonic waves and to connect to a receiver electrical storage device adapted and configured to store electrical energy based on the receiver electrical signal generated by the receiver transducer;

    a receiver communications device adapted and configured to send input to the sender, the input comprising the at least one configuration parameter; and

    a receiver controller coupled to at least one of the receiver transducer and the receiver electrical storage device.
