Abstract

A power receiver capable of receiving power from a power transmitter and configured to communicate with the power transmitter, the power receiver has a communication module and a power receiver. The communication module is configured to transmit first device information, which is device information of the power receiver, to the power transmitter, receive second device information, which is device information of the power transmitter, transmitted from the power transmitter which has authenticated, based on the first device information, the power receiver as a target of power transfer, and then, transmit, to the power transmitter, an identification code corresponding to the second device information used to determine whether to establish a communication with the power transmitter. The power receiver is configured to receive power from the power transmitter which has authenticated the power receiver.

Claims

1. A power receiver capable of receiving power from a power transmitter and configured to communicate with the power transmitter, the power receiver comprising:

a communication module configured to

transmit first device information, which is device information of the power receiver, to the power transmitter,

receive second device information, which is device information of the power transmitter, transmitted from the power transmitter which has authenticated, based on the first device information, the power receiver as a target of power transfer, and then,

transmit, to the power transmitter, an identification code corresponding to the second device information used to determine whether to establish a communication with the power transmitter; and

a power receiver configured to receive power from the power transmitter which has authenticated the power receiver.

2. The device of claim 1, wherein the communication module is configured to transmit the identification code corresponding to the second device information without user'"'"'s instruction.

3. The device of claim 1, wherein the communication module is configured to

transmit a pairing request to the power transmitter,

receive a pairing mode transition notification from the power transmitter whose mode has shifted to a pairing mode according to the paring request, and then,

transmit the identification code corresponding to the second device information to the power transmitter.

4. The device of claim 1, further comprising a storage in which the identification code is stored associated with the second device information.

5. The device of claim 1, wherein the communication module is configured to transmit data to be played by the power transmitter after the communication with the power transmitter has established.

6. The device of claim 1, further comprising a rechargeable battery charged by the power the power receiver receives.

7. The device of claim 6, wherein the communication module is configured to transmit data to be played by the power transmitter after the communication with the transmitter has established, and

when the rechargeable battery is charged with a first level, the communication module stops transmitting the data.

8. A power receiver configured to communicate with a power transmitter, the power receiver comprising:

a communication module configured to transmit first device information, which is device information of the power receiver, to the power transmitter; and

a power receiver configured to receive power from the power transmitter which has authenticated the power receiver based on the first device information,

wherein the communication module is configured to transmit, to the power transmitter, a first identification code used to determinate whether to establish a communication with the power transmitter while the power receiver is receiving the power from the power transmitter.

9. The device of claim 8, wherein the communication module is configured to transmit the first identification code without user'"'"'s instruction.

10. The device of claim 8, wherein the communication module is configured to

transmit a paring request to the power transmitter, and then,

transmit the first identification code to the power transmitter.

11. The device of claim 8, further comprising a storage in which the first identification code is stored.

12. The device of claim 8, wherein the communication module is configured to transmit data to be played by the power transmitter after the communication with the transmitter has established.

13. The device of claim 8, further comprising a rechargeable battery charged by the power the power receiver receives.

14. The device of claim 13, wherein the communication module is configured to transmit data to be played by the power transmitter after the communication with the transmitter has established, and

when the rechargeable battery is charged with a first level, the communication module stops transmitting the data.

15. A power transfer and receiving system comprising:

a power transmitter configured to transmit power; and

a power receiver capable of receiving power from the power transmitter and configured to communicate with the power transmitter,

wherein the power receiver comprises;

a first communication module configured to

transmit first device information, which is device information of the power receiver, to the power transmitter,

receive second device information, which is device information of the power transmitter, transmitted from the power transmitter which has authenticated, based on the first device information, the power receiver as a target of power transfer, and then,

transmit, to the power transmitter, an identification code corresponding to the second device information used to determine whether to establish a communication with the power transmitter; and

a power receiver configured to receive power from the power transmitter which has authenticated the power receiver,

wherein the power transmitter comprises;

an authenticator configured to authenticate the power receiver as a target of power transfer based on the first, device information;

a second communication module configured to transmit the second device information to the authenticated power receiver, and to establish the communication with the power receiving module based on the identification code; and

a power transmitter configured to transmit the power to the authenticated power receiver.

16. The system of claim 15, wherein the first communication module is configured to transmit the identification code corresponding to the second device information without user'"'"'s instruction.

17. The system of claim 15, wherein the first communication module is configured to

transmit a pairing request to the power transmitter,

receive a pairing mode transition notification from the power transmitter whose mode has shifted to a pairing mode according to the paring request, and then,

transmit the identification code corresponding to the second device information to the power transmitter.

18. The system of claim 15, wherein the power receiver further comprises a storage in which the identification code is stored associated with the second device information.

19. The system of claim 15, wherein the first communication module is configured to transmit data to be played by the power transmitter after the communication with the power transmitter has established.

20. The system of claim 19, wherein the power transmitter further comprises a player configured to play the data.
