1. A method for wireless power transmission comprising:

  • generating, by an imaging sensor in communication with a transmitter, visual imaging data for a living being or sensitive object within at least a portion of a transmission field of the transmitter;

    generating, by at least two ultrasound transducers in communication with the transmitter, ultrasound detection data identifying one or more objects;

    determining, by the transmitter, a location of the living being or the sensitive object in the transmission field based upon the visual imaging data and the ultrasound detection data; and

    transmitting, by the transmitter, power waves that converge at a location of a receiver based upon the location of the living being or sensitive object.
