Abstract: A multipurpose wireless touchpad mouse includes a mouse body, a first button set and a second button set respectively mounted in the top and bottom sides of the mouse body, and a control module mounted in an accommodation chamber inside the mouse body and electrically connected with the first button set and the second button set for sensing the upside-up position or upside-down position of the mouse body by means of a direction sensor and for enabling a changeover switch controller thereof to switch between the first button set and the second button set subject to the upside-up or upside-down position of the mouse body sensed by the direction sensor so that the mouse body can be used with the first button set as a mouse, or used with the second button set as a remote controller, laser pointer, A/V controller, presentation remote controller, direction controller or game controller.

Abstract: A cursor control device having a low profile characteristic is disclosed to include a module holder defining an accommodation space and a slot, an operation module having a carrier frame mounted in the accommodation space and inserted through the slot, a rolling roll rotatably and axially movably set in a rotation groove on the carrier frame outside the module holder, and a circuit module having a microprocessor and a sensor module mounted in carrier frame outside the rotation groove and electrically connected with the microprocessor for detecting the direction and amount of movement of the rolling roll. The rolling roll can be directly removed from the carrier frame by the user for cleaning or for a replacement.

Abstract: A touchpad mouse wakeup circuit arrangement is disclosed to include a control circuit installed in a touchpad mouse and consisting of a microprocessor, a touch panel, a vibration sensor and a power supply module. The vibration sensor detects a micro vibration and provides a voltage signal to the microprocessor when a user touches the housing of the touchpad mouse, causing the microprocessor to output a triggering signal to wakeup the touchpad mouse and to start the power supply module.
