1. A method for wireless power transmission to an electronic device from a computer system, comprising the steps of:

  • transmitting power sound waves from a first pocket-forming transmitter having a radio frequency integrated circuit, transducer elements, a microprocessor and communication circuitry thereby generating pockets of energy having sound waves that converge in three-dimensional space at predetermined locations, wherein the first pocket-forming transmitter is embedded in a screen display of the computer system;

    converting the pockets of energy from the first pocket-forming transmitter to by a first receiver to power the electronic device, wherein the first receiver has sensor elements and communication circuitry integrated within the electronic device,wherein the computer system includes a second receiver whereby a second pocket-forming transmitter in proximity to the computer system powers the computer system while the first pocket-forming transmitter of the computer system wirelessly charges the electronic device;

    upon a communication between the computer system and the second transmitter that is within a predetermined charging range of the computer system, verifying a battery charge level of the computer system;

    charging, by the second receiver, the computer system; and

    identifying peripheral devices within a predetermined range of the first pocket-forming transmitter for wirelessly charging the peripheral devices.
