Power saving wake-up device for wireless mouse
A power saving wakeup device for wireless mouse is disclosed. The wireless mouse has a microprocessor with a wake-up pin, and is waked up from the power saving mode when the wake-up pin is triggered. The wakeup device includes a contact conductor and a flexible conductor. The contact conductor is connected to the wake-up pin of the microprocessor. The flexible conductor is connected to a predetermined voltage level and separated by a predetermined distance from the contact conductor, such that the flexible conductor can contact with the contact conductor when the flexible conductor is vibrated. Thus, when the wireless mouse is moved to cause the flexible conductor to contact with the contact conductor, the wake-up pin is triggered by the predetermined potential.
1. A power saving wake-up device for wireless mouse, the wireless mouse having a microprocessor with two wake-up pins, such that when the wireless mouse enters in a power saving mode to save power consumption and subsequently at least one wake-up pin used as a trigger source by the microprocessor is triggered, the wireless mouse in the power saving mode is waked up, the device comprising:
first to fourth conductive plates, which form a quadrilateral with separated adjacent laterals, wherein the first and the third conductive plates are opposite to each other and both connected to a predetermined voltage level, and the second and the fourth conductive plates are opposite to each other and connected to the respective wake-up pins of the microprocessor; and
a movable conductor, which is movably implemented in the quadrilateral and concurrently contacts with at most two adjacent conductive plates to thereby conduct the two conductive plates, such that when the wireless mouse is moved to cause the movable conductor to contact with the two conductive plates, the wake-up pin used as the trigger source by the microprocessor is triggered by the predetermined voltage level.
2. The power saving wake-up device as claimed in claim 1 , wherein the movable conductor is a metal ball.
3. The power saving wake-up device as claimed in claim 1 , wherein the quadrilateral is a square or rectangle.
4. The power saving wake-up device as claimed in claim 1 , wherein when the wireless mouse desires to enter in the power saving mode, the microprocessor sets the other two wake-up pins as trigger sources if one of the two wake-up pins is connected to the predetermined voltage level, and sets the two wake-up pins as trigger sources if the two wake-up pins are not connected to the predetermined potential.
5. The power saving wake-up device as claimed in claim 1 , wherein the wake-up pins of the microprocessor are preset to a high voltage level and the predetermined voltage level is a ground voltage level.
6. The power saving wake-up device as claimed in claim 1 , wherein the wake-up pins of the microprocessor are preset to a low voltage level and the predetermined voltage level is a positive high voltage level.
