Abstract

A feed system has a first electronic unit, a second electronic unit, and a feed unit. The first electronic unit and the feed unit are separated. The feed unit transmits power to a power reception section of the second electronic unit based upon result information of a first authentication between the first electronic unit and the second electronic unit. The feed unit performs a second authentication on the second electronic unit in conjunction with power transmission.

Claims (38)

1. A feed system comprising:

a first electronic unit configured to perform a first authentication between the first electronic unit and a second electronic unit, the first electronic unit is configured to perform a second authentication between the first electronic unit and the second electronic unit during a first wireless transmission of power to the second electronic unit; and

a feed unit configured to initiate the first wireless transmission after the first electronic unit has performed the first authentication, the feed unit is configured to initiate a second wireless transmission of the power to the second electronic unit after the first electronic unit has performed the second authentication.

2. The feed system according to claim 1 , wherein the first electronic unit is configured to supply the power to the feed unit.

3. The feed system according to claim 1 , wherein the second electronic unit is configured to communicate with the first electronic unit by either a wireless communication or a wired communication.

4. The feed system according to claim 1 , wherein the first electronic unit is separate from the feed unit.

5. The feed system according to claim 1 , wherein the feed unit includes a detection section.

6. The feed system according to claim 5 , wherein the detection section is configured to detect a foreign metal on the feed unit.

7. The feed system according to claim 5 , wherein the detection section is configured to detect a characteristic from the group consisting of a temperature around the feed unit and a pressure around the feed unit.

8. The feed system according to claim 1 , wherein the feed unit includes an external power source input section configured to receive the power from a source external to the feed system.

9. The feed system according to claim 1 , wherein the first electronic unit comprises a control section configured to manage a number of objects to be charged.

10. The feed system according to claim 1 , wherein the first electronic unit comprises a control section configured to carry out a control function of charging.

11. The feed system according to claim 1 , wherein the first electronic unit comprises a control section configured to carry out a proper power distribution function.

12. The feed system according to claim 1 , wherein the first electronic unit comprises one of a television receiver, an image read/write apparatus, and a game machine.

13. The feed system according to claim 1 , wherein the feed unit is configured to use of at least one of a magnetic field and an electric field coupling to transmit the power to the second electronic unit.

14. A method of performing a charging operation in a feed system, the method comprising:

performing, by a first electronic unit, a first authentication between the first electronic unit and a second electronic unit;

performing, by the first electronic unit, a second authentication between the first electronic unit and the second electronic unit during a first wireless transmission of power to the second electronic unit;

initiating, by a feed unit, the first wireless transmission after the first electronic unit has performed the first authentication; and

initiating, by the feed unit, a second wireless transmission of the power to the second electronic unit after the first electronic unit has performed the second authentication.

15. The method according to claim 14 , further comprising:

supplying, by the first electronic unit, the power to the feed unit.

16. The method according to claim 14 , further comprising:

communicating with the first electronic unit, by the second electronic unit, by either a wireless communication or a wired communication.

17. The method according to claim 14 , further comprising:

detecting, by the feed unit, a foreign metal on the feed unit.

18. The method according to claim 14 , further comprising:

detecting, by the feed unit, a characteristic from the group consisting of a temperature around the feed unit and a pressure around the feed unit.

19. The method according to claim 14 , further comprising:

receiving, by the feed unit, the power from a source external to the feed system.

20. The method according to claim 14 , further comprising:

managing, by the first electronic unit, a number of objects to be charged.

21. The method according to claim 14 , further comprising:

carrying out, by the first electronic unit, a control function of charging.

22. The method according to claim 14 , further comprising:

carrying out, by the first electronic unit, a proper power distribution function.

23. The method according to claim 14 , further comprising:

transmitting, by the feed unit, the power to the second electronic unit using at least one of a magnetic field and an electric field coupling to transmit the power.
