  • Publication number: 20230418341
    Abstract: A touchpad apparatus including a holder bracket; a holder body; a plurality of elastic articles; and a touchpad printed circuit board (PCB) coupled to the first side of the holder body, the touchpad PCB including a switch member positioned at a first end of the touchpad PCB, wherein, when the holder body is in a first positional state, the plurality of elastic articles are in a first elastic state such that the switch member is disengaged, wherein, when the holder body is in a second positional state, the plurality of elastic articles are in a second elastic state such that the switch member is engaged to provide a signal indicating the second positional state of the holder body.

  • Patent number: 11733743
    Abstract: An innovative palmrest assembly for a computer has fewer components and reduces costs. The palmrest assembly has a cover that holds a tactile pointing device (such as a touch/click pad). The cover, though, is integrally molded with a holder for the tactile pointing device. The cover thus includes a molded pocket or recess into which the tactile pointing device is inserted, perhaps in a snap-fit arrangement. Because the tactile pointing device snuggly fits into the cover, the palmrest assembly has fewer components and fastening screws may be eliminated. Moreover, the cover may further include one or more elastomeric springs that are integrally molded with the holder for the tactile pointing device. The integrally-molded elastomeric springs further reduce componentry and eliminate complicated assembly operations. When a user taps or clicks the tactile pointing device, the elastomeric springs slightly compress and then rebound, thus providing a return motion to the tactile pointing device.

  • Patent number: 8223487
    Abstract: An electronic device including a main body, a display, and a light emitting module is provided. The main body has a restrictive opening. A pivoting side of the display is pivoted to the main body. A side of the display away form the pivoting side has a latch structure protruding from a first surface of the display. The light emitting module is disposed at the latch structure. When the display is opened relative to the main body, the light emitting module emits light toward a second surface of the main body to illuminate the second surface of the main body. When the display is closed relative to the main body, the latch structure is accommodated in the restrictive opening.
