A wireless power transmission apparatus includes patch antennas which form an RF wave; a memory storing electromagnetic wave distribution maps corresponding to transmission conditions for transmitting the RF wave; and a processor configured to determine a position of an electronic device and a position of a living body, determine a transmission condition which transmits the RF wave which causes an electromagnetic wave having a size not exceeding a first threshold value to be applied to a position of the living body while being beam-formed at a position of the electronic device, using at least a portion of the electromagnetic wave distribution maps, and generate the RF wave with the determined transmission condition using the patch antennas, each electromagnetic wave distribution map indicating the size of electromagnetic waves at one or more points around the wireless power transmission apparatus when the RF wave is formed by each of the transmission conditions.

Wireless power transmission apparatus and control method thereof

Provided is a device for transmitting wireless power. The wireless power transmitting device includes a communication unit, a power receiving unit, and a processor. The processor is configured to obtain, through the communication unit, communication establishment information and location information associated with a wireless charging area from a tag device, establish, through the communication unit, communication with a wireless power transmitting device based on the communication establishment information, and control to transmit the location information to the wireless power transmitting device. The power receiving unit wirelessly receives the power from the wireless power transmitting device after the communication unit transmits the location information.

Method and device for wirelessly transmitting power

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.

Wireless power transmitting device and method for controlling the same

According to an embodiment a wireless power transmitting device, includes a power transmission antenna including patch antennas to wirelessly transmit power, and communication antennas configured to receive a communication signal from an electronic device. The wireless power transmitting device also includes a processor configured to detect a direction in which the electronic device is positioned based on the communication signal received through the communication antennas and control the power transmission antenna to transmit the power in the detected direction.

A method of controlling a terminal is provided. The method includes determining a current status of at least one of the terminal and a peripheral environment of the terminal based on information obtained by using at least one sensor from a predetermined list of a plurality of statuses regarding the terminal or the peripheral environment of the terminal, determining an operation schedule of the at least one sensor based on the determined current status and the information obtained by using the at least one sensor, and controlling the at least one sensor to operate based on the determined operation schedule.

Terminal controlling method and terminal therefor

A method of recommending a friend in a first terminal is provided. The method includes generating first interest keyword information by analyzing event information of the first terminal, receiving second interest keyword information of a second terminal, comparing the first interest keyword information and the second interest keyword information, and displaying information recommending a user of the second terminal as a friend based on a result of the comparing.

Method of recommending friends, and server and terminal therefor
