  • Publication number: 20120206359
    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.

  • Publication number: 20110219923
    Abstract: A gathering method for a keypad fabrication process, in which a key-top tree is placed into a punching die, the punching die is aligned, a receiving device is disposed under the punching die, an assembly jig is disposed on the receiving device and aligned using an x-y table for gathering a punched-out key-top, a punch disposed above the punching die using another x-y table for allowing the punching die to perform both punching the key-top tree and gathering the punched-out part onto the assembly jig. Each key-top on the key-top tree is punched out and gathered on the assembly jig by repeating the aforementioned steps. Accordingly, the key-tops can be punched out and arranged on the assembly jig with a different pitch from the key-top tree automatically, fast and correctly. A gathering apparatus for a keypad fabrication process is also provided.

  • Patent number: 7732971
    Abstract: A carbon brush holder includes an insulated housing having a through hole with a first section, a second section and a stepped portion between the first and second sections. A carbon brush-holding member is inserted into the first section of the insulated housing and has a first end face, a second end face opposite to the first end face, and an insertion portion adjoined with the second end face. The insertion portion of the carbon brush-holding member extends into the second section of the insulated housing, thereby enabling the second end face of the carbon brush-holding member to be located in the second section of the insulated housing. Thus, the second end face of the carbon brush-holding member can firmly contact a conductive member that is disposed inside the second section of the insulated housing and electrically connected with a carbon brush inserted into the carbon brush-holding member.
