Abstract

An information processing apparatus is provided. The information processing apparatus includes a communication circuitry with an external apparatus in a noncontact manner by using a carrier of a predetermined frequency and charging an external battery in a noncontact manner; and a control circuitry configured to control a characteristic of at least one of communication and charging.

Claims

1. An information processing apparatus comprising:

a communication circuitry with an external apparatus in a noncontact manner by using a carrier of a predetermined frequency and charging an external battery in a noncontact manner; and

a control circuitry configured to control a characteristic of at least one of communication and charging,

wherein the communication circuitry includes

a resonance circuit having a coil that has a predetermined inductance and a capacitor that has a predetermined electrostatic capacity, and

a Q value changing circuit configured to selectively enable a load for changing a Q value or change a resistance value of the load.

2. An information processing apparatus comprising:

a communication circuitry with an external apparatus in a noncontact manner by using a carrier of a predetermined frequency and charging an external battery in a noncontact manner;

and a control circuitry configured to control a characteristic of at least one of communication and charging,

wherein the communication circuitry includes

a resonance circuit having a first coil that has a predetermined inductance and a capacitor that has a predetermined electrostatic capacity, and

a circuit that is placed near the resonance circuit, that is selectively enabled to change a Q value, that is electrically insulated from the resonance circuit, and that has a second coil.

3. An information processing apparatus comprising:

a communication circuitry with an external apparatus in a noncontact manner by using a carrier of a predetermined frequency and charging an external battery in a noncontact manner;

and a control circuitry configured to control a characteristic of at least one of communication and charging,

wherein the control circuitry is configured to;

obtain a response signal that is transmitted from the external apparatus, that is a response to charging authentication information transmitted to the external apparatus, and that serves as information about charging of the battery, and

obtain charging continuation information that is intermittently transmitted from the external apparatus during charging of the battery and that serves as information about charging of the battery,

wherein the control circuitry determines whether charging of the battery is to be performed or not on the basis of the response signal or the charging continuation information, and

wherein the setting circuitry sets a Q value of the communication circuitry to a first value when the determining unit determines that charging of the battery is to be performed and sets the Q value of the communication circuitry to a second value when the control circuitry determines that charging of the battery is not to be performed.

4. The information processing apparatus according to claim 3,

further comprising:

a power transmitting circuitry configured to transmit power for charging the battery to the external apparatus; and

a power transmission stop circuitry configured to stop transmission of the power by the power transmitting circuitry when the charging continuation information obtaining circuitry stops obtaining the charging continuation information that is intermittently obtained.
