Abstract: The present disclosure relates to a device and method for wireless power transfer to multiple devices using a multi-coil. The device disclosed in the specification comprises: a power pickup unit configured to receive wireless power from a wireless power transfer device having a plurality of primary coils at an operation frequency by magnetic coupling to the wireless power transfer device and convert an alternating current signal generated by the wireless power into a direct current signal; a communication/control unit including an in-band communication module configured to be supplied with the direct current signal from the power pickup unit and perform communication with the wireless power transfer device by using the operating frequency, and an out-band communication module configured to perform communication with the wireless power transfer device by using a frequency other than the operating frequency; and a load configured to be supplied with the direct current signal from the power pickup unit. In a one-to-multiple wireless power transfer system using a multi-coil, various applications of wireless power can be efficiently supported by defining configuration information, control information, management information, and procedures for the exchanges thereof as an out-band communication protocol.

Abstract: The present disclosure relates to a method and apparatus for controlling a power by using the Bluetooth Low Energy technology performed by a control device. According to the present disclosure, the method and apparatus includes establishing a connection with a first device and a second device through Bluetooth Low Energy (BLE) and receiving, from the first device, a first request message for requesting a transmission power change of the first device.
In addition, the method and apparatus includes receiving, from the second device, a second request message for requesting a transmission power change of the second device and changing a transmission power of the control device to a specific transmission power value based on the first change value and the second change value.

Abstract: The present invention relates to a method and an apparatus for calling a voice recognition service by using Bluetooth low energy (LE). In particular, a method performed by a first device may comprise the steps of: receiving a first request message requesting start of a voice recognition service, from a second device connected to the first device through Bluetooth communication, wherein the first request message is generated by generation of a first wake word pre-configured in the second device; executing a voice gateway connected to multiple voice managers in response to the first request message; and executing a voice recognition service between the second device and a first voice manager determined by the voice gateway among the multiple voice managers.
