1. A receiver device embedded in an electronic device comprising:

  • a processor;

    an antenna element configured to;

    receive one or more power transmission waves from a transmitter device that converge to form a pocket of energy, andgenerate an electrical current by receiving energy from the one or more power transmission waves, wherein the electrical current is in an alternating current form of electricity;

    a rectifier coupled to the antenna element and configured to rectify the alternating current form of electricity into a direct current form of electricity;

    a power converter coupled to the rectifier and configured to generate a constant voltage output of electrical current in the form of direct current, wherein;

    the power converter is communicatively coupled to the electronic device and is configured to provide the constant voltage output of electrical current in the form of direct current to the electronic device, andthe receiver device provides the direct current to the electronic device; and

    the processor of the receiver device is configured to control a built-in wireless communications component of the electronic device to transmit a communication signal to the transmitter device,wherein the communication signal contains data used to identify a location of the receiver device relative to the transmitter device, and the receiver device does not include a wireless transmitter.
