Computer pointing device with motion-driven electromagnetic induction module

Abstract

In one embodiment, a computer pointing device is provided with a navigation module, an electronic control system, and a motion-driven electromagnetic induction module. The electronic control system serves to activate and deactivate the navigation module. At times, the control system enters a sleep mode and deactivates the navigation module. In response to movement of the computer pointing device, the motion-driven electromagnetic induction module generates an output signal that wakes the control system and activates the navigation module. In another embodiment, a computer pointing device is provided with a housing, a battery, and a motion-driven electromagnetic induction module. The electromagnetic induction module is coupled to the battery, is enclosed within the housing, and is unconnected to any externally manipulable portion of the computer pointing device. Movement of the computer pointing device causes the electromagnetic induction module to charge the battery.
