Abstract

A power charging system is provided. The power charging system may have an information processing apparatus having a first communication unit and a power receiving unit, and an external apparatus having a second communication unit and a power transmission unit. The second communication unit may be configured to wirelessly communicate with the first communication unit using a first carrier wave having a first frequency and the power transmission unit may be configured to wirelessly transmit power to the power receiving unit using a second carrier wave having a second frequency, the second frequency being different from the first frequency.

Claims

1. An information processing apparatus, comprising:

a resonance circuit configured to;

communicate with an external apparatus by a first carrier wave of a first frequency;

receive, via the communication of the first frequency, frequency information from the external apparatus; and

wirelessly receive power from the external apparatus based on the received frequency information, and

a setting unit configured to change a resonance frequency of the resonance circuit from the first frequency to a second frequency for the wireless reception of the power, wherein

the resonance frequency is changed to the second frequency based on frequency information communicated from the external apparatus by the first carrier wave of the first frequency, and

the frequency information indicates the second frequency.

2. The information processing apparatus of claim 1, wherein the setting unit is further configured to change the resonance frequency to the second frequency based on a request for wireless charging operation communicated from the external apparatus.

3. The information processing apparatus of claim 2, wherein the request comprises the frequency information.

4. The information processing apparatus of claim 1, wherein the first frequency is different from the second frequency.

5. The information processing apparatus of claim 1, wherein the first frequency is approximately 13.56 MHz.

6. The information processing apparatus of claim 1, further comprising a filter configured to suppress application of a second carrier wave having the second frequency to the resonance circuit.

7. A method, comprising:

communicating, by a resonance circuit, with an external apparatus by a carrier wave of a first frequency;

receiving, by the resonance circuit and via the communication of the first frequency, frequency information from the external apparatus;

wirelessly receiving, by the resonance circuit, power from the external apparatus based on the received frequency information; and

changing, by a setting unit, a resonance frequency of the resonance circuit from the first frequency to a second frequency for the wireless reception of the power, wherein

the resonance frequency is changed to the second frequency based on frequency information communicated from the external apparatus by the carrier wave of the first frequency, and

the frequency information indicates the second frequency.

8. A non-transitory computer-readable medium having stored thereon computer-executable instructions that, when executed by an information processing apparatus, cause the information processing apparatus to execute operations, the operations comprising:

communicating, by a resonance circuit of the information processing apparatus, with an external apparatus by a carrier wave of a first frequency;

receiving, by the resonance circuit and via the communication of the first frequency, frequency information from the external apparatus;

wirelessly receiving, by the resonance circuit, power from the external apparatus based on the received frequency information; and

changing, by a setting unit of the information processing apparatus, a resonance frequency of the resonance circuit from the first frequency to a second frequency for the wireless reception of the power, wherein

the resonance frequency is changed to the second frequency based on frequency information communicated from the external apparatus by the carrier wave of the first frequency, and

the frequency information indicates the second frequency.
