Abstract

An electronic apparatus includes a power receiving unit that receives electric power supplied from the power supply apparatus in a non-contact manner; and a control unit that controls the electronic apparatus to be set in a second state until a predetermined time elapses since identification information is assigned from the power supply apparatus and controls the electronic apparatus to be set in a first state if the predetermined time has elapsed, wherein, if the power supply apparatus detects an electronic apparatus that is set in the first state, the power supply apparatus assigns identification information to the detected electronic apparatus.

Claims

1. An electronic apparatus comprising:

a power receiving unit that receives power from a power supply apparatus wirelessly;

a receiving unit that receives data from the power supply apparatus; and

a control unit that (a) obtains first identification information from data which is received by the receiving unit, (b) performs a predetermined process to cause the power supply apparatus to transmit data, including identification information, to the electronic apparatus again after the first identification information is obtained, and (c) obtains second identification information from data, received by the receiving unit, after the first identification is obtained, and (d) stores the second identification information in a recording unit, wherein the predetermined process includes a process for changing a state of the electronic apparatus.

2. The electronic apparatus according to claim 1, wherein the control unit deletes the first identification information from the recording unit if the state of the electronic apparatus is changed after the first identification is obtained.

3. The electronic apparatus according to claim 1, further comprising:

a count unit that detects a number of times that identification information is obtained from the power supply apparatus

wherein the control unit performs the predetermined process until the number of times is equal to or more than a predetermined value.

4. The electronic apparatus according to claim 1, wherein the predetermined process includes a process for changing the state of the electronic apparatus from a second state to a first state, wherein the first state is a state where power to be received via the power receiving unit is supplied to a predetermined unit, and the second state is a state where power to be received via the power receiving unit is not supplied to the predetermined unit.

5. The electronic apparatus according to claim 4, wherein the predetermined process includes a process for changing the state of the electronic apparatus to the second state after the first identification information is obtained.

6. The electronic apparatus according to claim 1, wherein the predetermined process includes a process for changing the state of the electronic apparatus from a second state to a first state, wherein the first state is a state where power to be received via the power receiving unit is supplied to a battery connected to the electronic apparatus, and the second state is a state where power to be received via the power receiving unit is not supplied to the battery.

7. The electronic apparatus according to claim 6, wherein the predetermined process includes a process for changing the state of the electronic apparatus to the second state after the first identification information is obtained.

8. The electronic apparatus according to claim 1, wherein the control unit causes the power supply apparatus to detect the electronic apparatus as a new apparatus by performing the predetermined process.

9. The electronic apparatus according to claim 1, wherein the control unit causes the power supply apparatus to detect that charging of the electronic apparatus is finished by performing the predetermined process.

10. The electronic apparatus according to claim 1, wherein the control unit controls the electronic apparatus based on control data, including the second identification information, if the receiving unit receives the control data after the second identification information is stored in the recording unit.

11. The electronic apparatus according to claim 1, wherein the electronic apparatus includes at least one of a mobile phone, a player, and a camera.

12. The electronic apparatus according to claim 1, wherein the second identification information is used for controlling the electronic apparatus.

13. A control method for controlling an electronic apparatus, the control method comprising:

receiving power from a power supply apparatus wirelessly;

receiving data from the power supply apparatus;

obtaining first identification information from data which is received from the power supply apparatus;

performing a predetermined process to cause the power supply apparatus to transmit data, including identification information, to the electronic apparatus again after the first identification information is obtained, wherein the predetermined process includes a process for changing a state of the electronic apparatus;

obtaining second identification information from data which received from the power supply apparatus after the first identification information is obtained, and

storing the second identification information in a recording unit.

14. The control method according to claim 13, further comprising:

deleting the first identification information from the recording unit if the state of the electronic apparatus is changed after the first identification information is obtained.

15. The control method according to claim 13, further comprising:

detecting a number of times that identification information is obtained from the power supply apparatus, and

performing the predetermined process until the number of times is equal to or more than a predetermined value.

16. The control method according to claim 13, wherein the predetermined process includes a process for changing the state of the electronic apparatus from a second state to a first state, wherein the first state is a state where power to be received via the power receiving unit is supplied to a predetermined unit, and the second state is a state where power to be received via the power receiving unit is not supplied to the predetermined unit.

17. The control method according to claim 16, wherein the predetermined process includes a process for changing the state of the electronic apparatus to the second state after the first identification information is obtained.

18. The control method according to claim 13, wherein the predetermined process includes a process for changing the state of the electronic apparatus from a second state to a first state, wherein the first state is a state where power to be received via the power receiving unit is supplied to a battery connected to the electronic apparatus, and the second state is a state where power to be received via the power receiving unit is not supplied to the battery.

19. The control method according to claim 18, wherein the predetermined process includes a process for changing the state of the electronic apparatus to the second state after the first identification information is obtained.

20. A non transitory storage medium storing a program, wherein the program causes a computer to perform a controlling method for controlling an electronic apparatus, the method comprising:

receiving power from a power supply apparatus wirelessly;

receiving data from the power supply apparatus;

obtaining first identification information from data which is received from the power supply apparatus;

performing a predetermined process to cause the power supply apparatus to transmit data, including identification information, to the electronic apparatus again after the first identification information is obtained, wherein the predetermined process includes a process for changing a state of the electronic apparatus;

obtaining second identification information from data which received from the power supply apparatus after the first identification information is obtained, and

storing the second identification information in a recording unit.
