  • Pointing stick with a rectangular-shaped hollow structure
    Patent number: 6697049
    Abstract: A pointing stick device has a substrate, a rectangular-shaped hollow structure installed on the substrate having a central axis substantially vertical to the substrate, at least one strain gauge installed on the rectangular-shaped hollow structure, and a claw structure. The claw structure has at least one claw, and is used to impart a pressure onto the rectangular-shaped hollow structure and curve the rectangular-shaped hollow structure. When the claw of the claw structure imparts pressure on the rectangular-shaped hollow structure, the strain gauge distorts, following the curve of the rectangular-shaped hollow structure, to produce corresponding pointing signals.

  • Control device and a notebook PC comprising the same
    Publication number: 20020067594
    Abstract: A control device, which is comprised of a sensor board that comprises a first through hole; at least one first sensor situated on the sensor board, provided to generate an inductive signal according to a distortion of the sensor board; a control post that passes through the first through hole; and a stopper, connected to one end of the post, and further connected to the sensor board, thus connecting the post to the sensor board. In this manner, the length of the control post can be increased without adding to the thickness of the notebook PC. Corresponding to applied force, the control post may produce larger torque, increasing the sensitivity of the control device.
