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 to communicate with an external apparatus and to wirelessly transmit power to the external apparatus using a first carrier wave of a first frequency; and

a setting unit to set a resonance frequency of the resonance circuit for wirelessly power transmitting to a second frequency.

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

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

4. The information processing apparatus of claim 1, wherein the setting unit is further configured to set the resonance frequency to the second frequency based on frequency information communicated to or from the external apparatus using the first carrier wave.

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

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

7. The information processing apparatus of claim 1, further comprising further comprising, a filter to suppress a second carrier wave having the second frequency from being applied to the resonance circuit.

8. A method, comprising:

communicating with an external apparatus and to wirelessly transmit power to the external apparatus using a first carrier wave of a first frequency; and

setting a resonance frequency of the resonance circuit for wirelessly power transmitting to a second frequency.

9. A non-transitory computer-readable storage medium having stored thereon, computer-executable instructions for causing an information processing apparatus to execute operations, the operations comprising:

communicating with an external apparatus and to wirelessly transmit power to the external apparatus using a first carrier wave of a first frequency; and

setting a resonance frequency of the resonance circuit for wirelessly power transmitting to a second frequency.
