  • Publication number: 20070139379
    Abstract: A solid-state roller on a pointing device with enhanced features. The solid-state design described herein allows the sensor to be placed on any shape of surface, such as one that has curvature in two directions. In one embodiment, a trench or downward curve contains sensors for detecting finger movement. The user's finger can thus bend about a knuckle in a curved motion to activate the sensor, requiring little or no movement of the finger up and down. The solid-state sensors can be of one of a number of designs. In one embodiment, multiple electrodes are contacted by a finger as it moves. Each electrode is coupled to a capacitive detection circuit, for detecting the change in capacitance as the electrode is contacted by the finger.

  • Patent number: 7180220
    Abstract: A motor carbon brush assembly is composed of an insulated holder, a first electrically conductive member, a resilient member, a second electrically conductive member, a carbon brush, a spring, and a rear cover. The resilient member includes a contact portion elastically deformable under pressure. The first conductive member and the resilient member are mounted respectively to the insulated holder. The second conductive member is held between the contact portion of the resilient member and the first conductive member to enable the first conductive member to be electrically connected with the second conductive member. The spring is connected with the carbon brush and the second conductive member. The second conductive member is held tight between the first conductive member and the resilient member to avoid disengagement from and imperfect contact with the first conductive member.
