Abstract: A touchpad module for a computing device is provided. A fixing frame is concavely formed in a casing of the computing device. The fixing frame includes a supporting part. The touchpad module is installed within the fixing frame. The touchpad module includes a touch member and a pressure sensing element. The touch member includes a covering plate and a circuit board. An edge part of covering plate is supported on the supporting part. The pressure sensing element is installed on the touch member and electrically connected with the circuit board. While the touch member is pressed, the touch member is bent downwardly. Consequently, the touch member has a deformation amount. According to the deformation amount, a magnitude of a pressing force exerted on the touch member is sensed, and a pressure sensing signal is generated.

Abstract: A touchpad module includes a base plate, a touch member, a supporting structure and a pressure sensing unit. The touch member is movable toward the base plate. The supporting structure is arranged between the base plate and the touch member. The pressure sensing unit is installed on the touch member. The pressure sensing unit is arranged between the touch member and the base plate. While the touch member is pressed in response to an external pressing force, the touch member is moved downwardly toward the base plate to compress the supporting structure. Consequently, the supporting structure is subjected to deformation, and the touch member has a displacement amount. According to the displacement amount, a magnitude of the pressing force is sensed by the pressure sensing unit, and a pressure sensing signal is outputted from the pressure sensing unit.

Abstract: A cooling fan includes a fan base, an impeller part, a driving part, an illumination circuit board and plural light-emitting elements. The driving part includes a shaft seat, a driving circuit board and plural coils. The driving circuit board is disposed on the fan base. The plural coils are arranged between the driving circuit board and the illumination circuit board and arranged around the shaft seat. The rotating shaft of the impeller part is inserted into the shaft seat. When an electric current flows through the plural coils, the rotating shaft is rotated. The plural light-emitting elements are disposed on the illumination circuit board. When the electric current flows through the plural light-emitting elements, the plural light-emitting elements emit light beams.
