Abstract

A wireless power transfer system is disclosed. A mouse system includes a mouse pad for wirelessly transmitting power and a wireless mouse for wirelessly receiving power. The mouse pad receives control information related to control of the position of a mouse pointer from the wireless mouse through wireless communication and transmits the received control information to a computer to control the position of the mouse pointer.

Claims

1. A wireless mouse for wirelessly receiving power from a mouse pad that wirelessly transmits power, the wireless mouse comprising:

a wireless power receiving module for receiving power wirelessly transmitted from the mouse pad;

a first wireless communication module for exchanging first control information with the mouse pad to control wireless reception of power from the mouse pad;

a second wireless communication module for transmitting second control information related to control of a position of a mouse pointer to the mouse pad; and

a sensor for sensing a moving operation or command input of the wireless mouse,

wherein the wireless mouse transmits a predetermined signal for interrupting wireless transmission of the power to the mouse pad through the first wireless communication module when the moving operation or command input of the wireless mouse is sensed by the sensor.

2. The wireless mouse according to claim 1, wherein the first wireless communication module communicates with the mouse pad through Bluetooth communication.

3. The wireless mouse according to claim 2, wherein the first wireless communication module exchanges the first control information with the mouse pad according to an Alliance for Wireless Power (A4WP) scheme, which is a standard related to a resonance type wireless charging scheme.

4. The wireless mouse according to claim 1, further comprising a timer, wherein the wireless mouse transmits a predetermined signal for requesting wireless transmission of the power to the mouse pad through the first wireless communication module when a predetermined time elapses after the moving operation or command input of the wireless mouse is sensed.

5. The wireless mouse according to claim 1, further comprising a rechargeable battery charged with the wirelessly received power, wherein the rechargeable battery is charged when the wireless mouse is placed on the mouse pad, and the wireless mouse is operated using the power charged in the rechargeable battery when the wireless mouse is not placed on the mouse pad.

6. The wireless mouse according to claim 5, further comprising an indicator for indicating a charged state of the rechargeable battery.

7. A mouse pad for wirelessly transmitting power to a wireless mouse capable of wirelessly receiving power, the mouse pad comprising:

a wireless power transmitting module for wirelessly transmitting power received from a power source to the wireless mouse;

a first wireless communication module for exchanging first control information with the wireless mouse to control wireless transmission of power to the wireless mouse;

a second wireless communication module for receiving second control information related to control of a position of a mouse pointer from the wireless mouse; and

a third communication module for transmitting the received second control information to a computer to control the position of the mouse pointer,

wherein the mouse pad interrupts wireless transmission of the power if a predetermined signal indicating that a moving operation or command input of the wireless mouse has been sensed is received from the wireless mouse through the second wireless communication module.

8. The mouse pad according to claim 7, wherein the first wireless communication module and the second wireless communication module communicate with the wireless mouse through Bluetooth communication.

9. The mouse pad according to claim 8, wherein the first wireless communication module exchanges the first control information with the wireless mouse according to an Alliance for Wireless Power (A4WP) scheme, which is a standard related to a resonance type wireless charging scheme.

10. The mouse pad according to claim 7, wherein the mouse pad receives a predetermined signal for requesting wireless transmission of the power through the first wireless communication module when a predetermined time elapses after the moving operation or command input of the wireless mouse is sensed and resumes wireless transmission of the power according to the request of wireless transmission of the power.

11. The mouse pad according to claim 7, further comprising an indicator for indicating a charged state of a rechargeable battery provided in the wireless mouse.

12. The mouse pad according to claim 7, wherein the mouse pad is interlocked with an external device through the first wireless communication module or the second wireless communication module and intermediates between the external device and the computer through the first wireless communication module or the second wireless communication module and the third communication module for information exchange therebetween.

13. The mouse pad according to claim 7, wherein the power source is the computer.

14. A mouse system comprising a mouse pad for wirelessly transmitting power and a wireless mouse for wirelessly receiving the power, wherein

upon receiving second control information related to control of a position of a mouse pointer from the wireless mouse through short distance wireless communication, the mouse pad transmits the received second control information to a computer through USB communication,

the wireless mouse wirelessly receives power from the mouse pad and exchanges first control information for controlling the wireless power with the mouse pad through the short distance wireless communication, and

the mouse pad interrupts wireless transmission of the power if a predetermined signal indicating that a moving operation or command input of the wireless mouse has been sensed is received from the wireless mouse through the second wireless communication module.
