摘要： Methods and apparatus for wireless charging are provided. Transmission power transmitted from a wireless power transmitter is received at a power receiver of a wireless power receiver. A battery of the wireless power receiver is charged with the received transmission power. It is determined whether the battery is fully charged. A packet from a communication unit of the wireless power receiver is transmitted to the wireless power transmitter when the battery is fully charged. An auxiliary charge of the battery is performed by receiving strength-reduced transmission power from the wireless power transmitter.

摘要： Disclosed is an apparatus and method for wirelessly transmitting power to power receivers from a power transmitter. The present disclosure provides a rational search procedure for locations of the power receivers, and provides a function of simultaneously charging multiple receivers using microwave multi-focusing. The wireless power transmission method performed by a power transmitter includes determining angular coordinates of the power transmitter in relation to a position of at least one power receiver; determining a distance between the at least one power receiver and the power transmitter based on the determined angular coordinates by using a focused microwave field; determining a location of the at least one power receiver based on the determined angular coordinates and the distance; and wirelessly transmitting power by focusing the microwave field to the determined location of the at least one power receiver.

摘要： A wireless power transmitting device is provided. The wireless power transmitting device may comprise an antenna, a memory, and a processor configured to control to store, as reference information, information of a first reflected signal of a pilot signal sent out through the antenna at a first time in the memory and control to compare the reference information with information about second reflected signals of a pilot signal sent out through the antenna at a second time, and determine a position of a target for detection based on a result of the comparison.

摘要： Disclosed is an electronic device including a resonator that generates an induced current by electromagnetic coupling. The resonator includes a first conductor, a plurality of second conductors, a one end of each of the second conductors being electrically coupled to a first point of the first conductor, and an other end of each of the second conductors being electrically coupled to a second point of the first conductor, and at least one impedance load connected with the second conductors in series or in parallel. Thus, the resonator may generate current through the first and second conductors.
