Embodiments disclosed herein may generate and transmit power waves that, as result of their physical waveform characteristics (eg, 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 (eg, transmission field) where energy may be harvested by a receiver positioned within or nearby the pocket of energy

Systems and methods for identifying sensitive objects in a wireless charging transmission field

Disclosed herein are systems and methods addressing the shortcomings in the art, and may also provide additional or alternative advantages as well. The embodiments described herein provide a wireless charging proximity transmitter configured to intelligently generate waveforms of various types, such as radio-frequency waves and ultrasound waves, among others. The wireless charging transmitter may be used for providing energy to a receiver that is proximately located to the transmitter. The receiver may be coupled to, or may be a component of, an electrical device that is intended to receive the power from the wave-based energy produced by the wireless proximity transmitter.

Identifying receivers in a wireless charging transmission field

Embodiments disclosed herein discloses a wireless charging system configured to generate and transmit power waves that, due to physical waveform characteristics 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 pocket of energy and then convert that energy into usable electric power for the electronic device associated with a receiver. The pocket 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. Video sensors capture actual video images of fields of view within the transmission field, and a processor identifies selected objects, selected events, and/or selected locations within the captured video images.

Systems and methods of object detection in wireless power charging systems

According to various embodiments, an electronic device for charging a battery of an external device may include a coil and a first circuit configured to wirelessly transmit power to the external device through the coil. A second circuit may be configured to wirelessly receive information from the external device. A fan may be disposed adjacent to the coil to discharge heat to the exterior of the electronic device. A control circuit may adjust the driving speed of the fan based at least in part on the received information.
