Abstract

In the first state in which the position of an external device is included in the first area where a power supply unit executes wireless power supply and is included in the second area wider than the first area where a communication portion performs communication, the power supply unit is controlled to execute wireless power supply. It is determined whether the state of the external device has transited from the first state to the second state in which the position of the external device is included in the second area and is outside the first area. If it is determined that the state has transited from the first state to the second state, information based on the power supply executed in the first state is communicated with the external device via the communication portion.

Claims19

Dependent claims

A system comprising:

a power supply apparatus configured to:
wirelessly supply power to a power receiving device only when the power receiving device is in a position within a first area of the power supply apparatus, and
wirelessly communicate, via near-field communication (NFC), with the power receiving device when the power receiving device is in a position within a second area of the apparatus, wherein the second area is wider than the first area;
and
the power receiving device configured to:
wirelessly receive power supplied from the power supplying apparatus;
and
via NFC, wirelessly communicate with the power supplying apparatus,
wherein the power supplying apparatus is further configured to:
wirelessly supply power to the power receiving device when the power receiving device is in a first state in which the position of the device is within the first area and the second area,
determine whether the state has transited from the first state to a second state in which the position of the power receiving device is within the second area but outside of the first area, based on wireless communication with the power receiving device via the NFC, and
communicate information to the power receiving device after the power receiving device has transited from the first state to the second state, wherein the information is based on the amount of power supplied by the power supplying apparatus in the first state, and
wherein the power receiving device is further configured to:
serve as an initiator of NFC to commence wireless communication with the power supplying apparatus via the NFC, and
serve as a target in a passive mode of NFC to receive the information communicated by the power receiving device.

12 more elements

A method of supplying power in a system including an power supplying apparatus and a power receiving device, the method comprising the steps of:

the power supplying apparatus:
wirelessly supplying power to the power receiving device only when the power receiving device has entered a position within a first area of the power supply apparatus, and
enabling, via NFC, wireless communication with the power receiving device when the power receiving device is in a position within a second area of the apparatus, where the second area is wider than the first area;
executing wireless power supply to the power receiving device when the power receiving device is in a first state in which the position of the power receiving device is within the first area and the second area;
determining whether the state has transited form the first state to a second state in which the position of the power receiving device is within the second area but outside of the first area, based on wireless communication with the power receiving device via the NFC, and
communicating information to the power receiving device after the power receiving device has transited from the first state to a second state, wherein the information is based on the amount of power supplied by the power supplying apparatus in the first state
the power receiving device:
serving as an initiator in the NFC, initiating NFC to commence wireless communication with the power supplying apparatus via the NFC,
wirelessly receiving power supplied from the power supplying apparatus,
enabling, via NFC, the wireless communication with the power supplying apparatus,
serving as a target in a passive mode, receiving the information communicated by the power receiving device.

8 more elements

A non-transitory computer-readable storage medium storing a program for controlling a power supplying apparatus to supply power to a power receiving device, the program comprising instructions for:

the power supplying apparatus to:
wirelessly supply power to the power receiving device only when the power receiving device has entered a position within a first area of the power supply apparatus, and
enable, via NFC, wireless communication with the power receiving device when the power receiving device is in a position within a second area of the apparatus, where the second area is wider than the first area;
execute wireless power supply to the power receiving device when the power receiving device is in a first state in which the position of the power receiving device is within the first area and the second area;
determine whether the state has transited form the first state to a second state in which the position of the power receiving device is within the second area but outside of the first area, based on wireless communication with the power receiving device via the NFC, and
communicate information to the power receiving device after the power receiving device has transited from the first state to a second state, wherein the information is based on the amount of power supplied by the power supplying apparatus in the first state;
and instructions for enabling the power receiving device to:
serve as an initiator in the NFC to commence wireless communication with the power supplying apparatus via the NFC,
wirelessly receive power supplied from the power supplying apparatus,
via NFC, wirelessly communicate with the power supplying apparatus, and
serve as a target in a passive mode to receive the information communicated by the power receiving device.
