摘要： In a power supply system for wirelessly supplying power between a power transmission device and a power reception device, the power transmission device includes a power transmission unit for generating supply power and transmitting the generated supply power to the power reception device; a power transmission side magnet for alignment with the power reception device; a magnetic sensor for detecting a magnetic force from a power reception side magnet provided in the power reception device; and a control unit for controlling the power transmission device. The power reception device includes: a power reception unit for receiving the supply power supplied from the power transmission device; the power reception side magnet for alignment with the power transmission device; and a control unit for controlling the power reception device. When the power transmission device and the power reception device are in close contact with each other, power is wirelessly transmitted from the power transmission unit to the power reception unit in a state in which the power transmission unit and the power reception unit are aligned by an attractive magnetic force between the power transmission side magnet and the power reception side magnet. When the power transmission device and the power reception device are apart from each other, the control unit of the power transmission device starts or stops power transmission from the power transmission unit according to a magnetic force detection signal from the power reception side magnet detected by the magnetic sensor.

摘要： A wireless connection system executes wireless connection between an information terminal of a user and a display device installed in environment. In a case where an information terminal existing in the vicinity thereof is detected, the display device displays device ID information related to authentication for wireless connection with the detected information terminal (or an image obtained by coding it) on a display screen. The information terminal confirms whether the device ID information read from the display screen match device ID information of an own device or not, and establishes wireless connection using an authentication ID for wireless connection with the display device after matching is confirmed. The display device establishes wireless connection with the information terminal using an authentication ID.

摘要： A wireless power receiving device (WPRD) comprises an RFID responder and a beacon signal oscillator to transmit an RFID response in a case where there is no electric power which is necessary for transmission of a beacon signal. A wireless power transmitting device (WPTD) operates in a wide area power transmission mode for transmitting the electric power at a wide angle toward a direction that it receives the RFID response. When the WPRD receives the electric power in a wide area power transmission mode and transmission of the beacon signal becomes possible, it transmits the beacon signal. The WPTD operates in a centralized power transmission mode for transmitting the electric power at a narrower angle toward a direction receiving the beacon signal. Also, during the centralized power transmission mode, it cyclically performs transmission and reception of the beacon signal to detect positions of the WPRD and the WPTD.
