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.
Claims31
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.
2 more elements
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.
2 more elements
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.
1 more element
A method comprising:
- causing a wireless communication unit to communicate with a first external device via a wireless communication path;
- causing a wireless power transmission unit 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;
- determining 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
- controlling 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.
2 more elements
A non-transitory storage medium that stores a program for causing a computer to execute a method, the method comprising:
- causing a wireless communication unit to communicate with a first external device via a wireless communication path;
- causing a wireless power transmission unit 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;
- determining 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
- controlling 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.
