SYSTEMS AND METHODS FOR IDENTIFYING SENSITIVE OBJECTS IN A WIRELESS CHARGING TRANSMISSION FIELD
First Claim
1. A system comprising:
- a transmitter configured to receive sensor data from a sensor device coupled to the transmitter, determine whether the sensor data identifies an object to avoid, and transmit one more power waves that avoid the object and converge to form a pocket of energy capable of being harnessed by a receiver to provide power to an electronic device coupled to the receiver.

Abstract
Embodiments disclosed herein may generate and transmit power waves that, as result of their physical waveform characteristics (e.g., frequency, amplitude, phase, gain, direction), converge at a predetermined location in a transmission field to generate a pocket of energy. Receivers associated with an electronic device being powered by the wireless charging system, may extract energy from these pockets of energy and then convert that energy into usable electric power for the electronic device associated with a receiver. The pockets of energy may manifest as a three-dimensional field (e.g., transmission field) where energy may be harvested by a receiver positioned within or nearby the pocket of energy.

2. A method for wireless power transmission comprising:
-
transmitting, by a transmitter, power waves that converge in a three dimensional space to form one or more first pockets of energy at a predetermined location for receiving by an antenna element of a receiver, wherein the receiver is configured to harvest power from the one or more first pockets of energy at the predetermined location; acquiring, by at least one sensor in communication with the transmitter, data indicating presence of a living being or a sensitive object; obtaining, by the transmitter, information relating to a location of the living being or the sensitive object based upon the data indicating the presence of the living being or the sensitive object; and determining, by the transmitter, whether to adjust a power level of the power waves that converge in the three dimensional space to form the one or more first pockets of energy at the predetermined location in response to the information relating to the location of the living being or the sensitive object. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 25)

17. A transmitter for wireless power transmission comprising:
-
at least two antennas; a controller that controls power waves broadcast by the transmitter through the at least two antennas that converge in a three dimensional space to form one or more pockets of energy at a predetermined location for receiving by an antenna element of a receiver; a transmitter housing containing the at least two antennas; and at least one sensor located on the transmitter housing to sense presence of a living being or a sensitive object, and to communicate to the controller data relating to the presence of the living being or the sensitive object;
wherein the controller determines whether to adjust a power level of the power waves that converge in the three dimensional space to form the one or more pockets of energy at the predetermined location in response to the data relating to the presence of the living being or the sensitive object. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

26. A method for wireless power transmission, comprising:
-
transmitting, by a transmitter, power waves that converge in a three dimensional space to form a one or more pockets of energy at a predetermined location for receiving by antenna elements of a receiver, wherein the receiver harvests power from the one or more pockets of energy at the predetermined location; acquiring, by a plurality of sensors in communication with the transmitter, data indicating presence of a living being or a sensitive object; obtaining, by the transmitter, information relating to a location of the living being or the sensitive object based upon the data indicating the presence of the living being or the sensitive object; and at least reducing, by the transmitter, the power level of the power waves that converge in the three dimensional space to form the one or more pockets of energy at the predetermined location, when the data relating to the presence of the living being or the sensitive object indicates that the living being or the sensitive object is proximate to the three dimensional space at the predetermined location.
