1. A processor-based system for managing a wireless power transmission system comprising a plurality of power transmitters and a power receiver, the processor-based system comprising:

  • a transmitter manager that includes a processor;

    a database operatively coupled to the processor; and

    a communication apparatus, operatively coupled to the processor, wherein the communication apparatus is operable to communicate with the plurality of power transmitters and the power receiver in the wireless power transmission system,wherein the processor is configured to;

    assign the power receiver to a first power transmitter of the plurality of power transmitters, wherein the first power transmitter wirelessly transmits controlled radio frequency (RF) waves that converge and constructively interfere near the power receiver;

    receive and store system operation data associated with the power receiver in the database, wherein the stored system operation data is received from the first transmitter and is controlled by the transmitter manager, and the system operation data includes information used to determine a location of the power receiver;

    receive updated system operation data from the first power transmitter, wherein the updated system operation data comprises a change in the location of the power receiver;

    in accordance with a determination that the changed location of the power receiver is closest to the first power transmitter, instruct the first power transmitter to adjust the wireless transmission of the controlled RF waves based on the changed location; and

    in accordance with a determination that the changed location of the power receiver is closest to a second power transmitter of the plurality of power transmitters distinct from the first power transmitter, (i) assign control of the system operation data associated with the power receiver to the second power transmitter and (ii) instruct the second power transmitter to begin wirelessly transmitting additional controlled RF waves to the power receiver.
