Mouse pad comprising wireless power transmission apparatus and mouse

1. A mouse pad comprising:

a wireless power transmission apparatus comprising at least a first transmission coil and a second transmission coil and configured to wirelessly transmit power to a mouse placed on the mouse pad; and

a controller configured to:

directly receive determination information from a power supply connected to the mouse pad for selecting one transmission coil among the first transmission coil and the second transmission coil according to a movement of the mouse on the mouse pad, and

enable the second transmission coil and disable the first transmission coil when the movement of the mouse indicates the mouse is moving on the mouse pad from the first transmission coil to the second transmission coil.

2. The mouse pad according to claim 1 , further comprising:

a first communication unit configured to perform communication with the mouse in a first wireless communication scheme; and

a second communication unit configured to perform communication with the mouse in a second wireless communication scheme.

3. The mouse pad according to claim 2 , wherein the first communication unit is configured to receive motion information corresponding to the movement of the mouse from the mouse and transmit the motion information to the power supply to generate the determination information based on the motion information.

4. The mouse pad according to claim 2 , wherein the mouse transmits motion information indicating the movement of the mouse to the mouse pad using only the first wireless communication scheme.

5. The mouse pad according to claim 2 , wherein the mouse transmits motion information indicating the movement of the mouse to the first communication unit of the mouse pad and the first communication unit of the mouse pad transmits the motion information to the power supply.

6. The mouse pad according to claim 1 , wherein the wireless power transmission apparatus further comprises a coil selector configured to selectively enable and disable the first and second transmission coil.

7. The mouse pad according to claim 1 , wherein the controller comprises a communication unit for direct communication with the power supply.

8. The mouse pad according to claim 1 , further comprising:

a first communication unit configured to receive motion information corresponding to the movement of the mouse on the mouse pad from the mouse and transmit the motion information to the power supply to generate the determination information based on the motion information.

9. The mouse pad according to claim 8 , wherein the wireless power transmission apparatus further comprises a coil selector configured to selectively enable and disable the first and second transmission coils.

10. The mouse pad according to claim 1 , wherein the mouse directly transmits motion information indicating the movement of the mouse to the power supply without directly transmitting the motion information to the mouse pad.

11. The mouse pad according to claim 10 , wherein the power supply predicts the movement of the mouse on the mouse pad based on the motion information by mapping vector information of the mouse to an entire area of the mouse pad.

12. The mouse pad according to claim 1 , wherein the power supply communicates directly with the controller of the mouse pad, and the controller of the mouse pad controls a coil selector to disable the first transmission coil and enable the second transmission coil.

13. A wireless power transmission system comprising:

a mouse comprising:

a wireless power reception apparatus configured to wirelessly receive power;

a first controller configured to control an operation of the wireless power reception apparatus;

a motion sensor unit configured to obtain motion information generated according to a movement of the first mouse; and

a first communication unit configured to perform communication in one or more schemes; and

a mouse pad comprising:

a wireless power transmission apparatus comprising at least a first transmission coil and a second transmission coil and configured to wirelessly transmit power to the mouse; and

a controller configured to:

directly receive determination information from a power supply connected to the mouse pad for selecting one transmission coil among the first transmission coil and the second transmission coil according to a movement of the mouse on the mouse pad, and

enable the second transmission coil and disable the first transmission coil when the motion information indicates the mouse is moving on the mouse pad from the first transmission coil to the second transmission coil.

14. The wireless power transmission system according to claim 13 , wherein the power supply supplies a voltage to the wireless power transmission apparatus of the mouse pad, and

wherein the wireless power transmission apparatus generates the wireless power using the voltage supplied from the power supply.

15. The wireless power transmission system according to claim 13 , wherein the wireless power transmission apparatus further comprises a coil selector configured to selectively enable and disable the first and second transmission coils.

16. The wireless power transmission system according to claim 15 , wherein the mouse pad further comprises a communication unit configured to receive motion information corresponding to the movement of the mouse from the mouse and transmit the motion information to the power supply to generate the determination information based on the motion information.
