The processor detects the presence of a foreign object (FO) during a power-transfer session using Quality Factor (QF) values. Estimated QF parameters are determined via exponential curve fitting using peak values of a damped sinusoidal waveform generated by a resonant circuit. Then the estimated parameters in the exponential curve are used to calculate the QF, which provides a robust measurement result even in a noisy environment. | 2020-06-11 |
20200185975 | ELECTRONIC APPARATUS AND METHOD - According to one embodiment, transmission circuitry transmits power with a first electromagnetic wave in a first frequency band. A processor circuitry executes a carrier sense during a first period, in at least a second frequency band different from the first frequency band. The transmission circuitry transmits power with a second electromagnetic wave in the first frequency band in a second period following the first period, if a wireless signal is not detected by the carrier sense during the first period. The processor circuitry executes the carrier sense during a third period following the first period in the at least the second frequency band, if the wireless signal is detected by the carrier sense during the first period. | 2020-06-11 |
20200185976 | WIRELESS POWER TRANSMITTER FOR EXCLUDING CROSS-CONNECTED WIRELESS POWER RECEIVER AND METHOD FOR CONTROLLING THE SAME - A method and apparatus for controlling a wireless power transmitter configured to transmit power to a wireless power receiver is provided. The method includes receiving a first signal from the wireless power receiver, wherein the first signal comprises load detection indication bits, detecting a change in load of the wireless power transmitter caused by placement of the wireless power receiver in a charging area of the wireless power transmitter, based on the load detection indication bits, and determining whether to transmit a second signal to the wireless power receiver based on detecting the change in load of the wireless power transmitter. | 2020-06-11 |
