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 communication unit configured to wirelessly communicate with an external apparatus by use of a first carrier wave that has a first frequency received from the external apparatus;

a power transmission unit configured to wirelessly transmit power to the external apparatus by use of a second carrier wave of a second frequency, wherein the second frequency is different from the first frequency; and

a setting unit configured to set a resonance frequency of a resonance circuit to the second frequency based on frequency information communicated to or from the external apparatus.

2. The information processing apparatus of claim 1, wherein the second frequency is a harmonic or a sub-harmonic of the first frequency.

3. The information processing apparatus of claim 2, wherein the first frequency is approximately 13.56 MHz.

4. The information processing apparatus of claim 3, wherein the second frequency is approximately 3.39 MHz or approximately 6.78 MHz.

5. The information processing apparatus of claim 1, wherein the second frequency is a sub-harmonic of a third frequency, and the third frequency is approximately 27.12 MHz.

6. The information processing apparatus of claim 1, wherein the second frequency is a sub-harmonic of a third frequency, and the second frequency is 4.8 MHz and the third frequency is 19.2 MHz.

7. The information processing apparatus of claim 1, further comprising an integrated circuit chip and a filter arranged and configured so as to suppress the second carrier wave from being applied to the integrated circuit chip.

8. The information processing apparatus of claim 1, wherein the frequency information is associated with a request signal.

9. The information processing apparatus of claim 1, wherein the setting unit is further configured to set the resonance frequency of the resonance circuit to the first frequency based on a communication request communicated to or from the external apparatus.

10. An information processing apparatus, comprising:

a communication unit configured to wirelessly communicate with an external apparatus by use of a first carrier wave that has a first frequency received from the external apparatus;

a power transmission unit configured to wirelessly transmit power to the external apparatus by use of a second carrier wave of a second frequency, wherein the second frequency is different from the first frequency; and

a setting unit configured to set a resonance frequency of a resonance circuit to the second frequency based on a charging request communicated to or from the external apparatus.

11. The information processing apparatus of claim 10, wherein the charging request includes frequency information to set the second frequency.

12. The information processing apparatus of claim 10, wherein the setting unit is further configured to set the resonance frequency of the resonance circuit to the first frequency based on a communication request communicated to or from the external apparatus.

13. The information processing apparatus of claim 10, further comprising an integrated circuit chip and a filter arranged and configured so as to suppress the second carrier wave from being applied to the integrated circuit chip.

14. A method for use in a first apparatus which is operable with an external apparatus, the method comprising:
