1. A power-supplying device comprising:
- a communicating unit configured to wirelessly communicate with a first external device;
a power supply unit configured to supply power to a power-supplied external device different from the first external device;
a detecting unit configured to detect an error rate occurred between the communicating unit and the first external device; and
a control unit configured to perform, based on whether a change of the error rate between the communicating unit and the first external device is more than a predetermined value, a process for controlling power supply to the power-supplied external device from the power supply unit if the power supply unit supplies power to the power-supplied external device wirelessly, wherein the communicating unit uses a communication path which is different from a path used for power supplying by the power supply unit.

Abstract
A power-supplying device supplies the power to a power-supplied device in a non-contact manner, without interfering with communication between the power-supplying device and power-supplied device. More specifically, the power-supplying device supplies the power to the power-supplied device in a non-contact manner, such that the error rate of wireless communication does not increase.

6. A method comprising:
-
causing the power supplying device to communicate with a first external device wirelessly; causing a power supplying device to supply power to a power-supplied external device different from the first external device; detecting an error rate occurred between the power supplying device and the first external device; and performing, based on whether a change of the error rate between the power supplying device and the first external device is more than a predetermined value, a process for controlling power supply to the power-supplied external device from the power supplying device if the power supplying device supplies power to the power-supplied external device wirelessly, wherein a wireless communication performed by the power supplying device uses a communication path which is different from a path used for power supplying by the power supplying device. - View Dependent Claims (7, 8, 9, 10)

11. A power transmission device comprising:
-
a wireless communication unit that communicates with a first external device via a wireless communication path; a wireless power transmission unit configured to transmit power to a power-supplied external device, different from the first external device, via a wireless power transmission path different from the wireless communication path; and a control unit that (a) determines a state of communication between the wireless communication unit and the first external device when power is transmitted from the wireless power transmission unit to the power-supplied external device via the wireless power transmission path, and (b) controls power to be transmitted from the wireless power transmission unit to the power-supplied external device according to the determined state of communication between the wireless communication unit and the first external device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
