  • Patent number: 5313318
    Abstract: This invention provides a thin, light assembly for a LCD, light guide and circuitry by using an internal frame with a central opening, above which is mounted a LCD and below which is mounted a light guide for directing light through the opening into the display. To one side of the light guide is mounted a light bulb for introducing light into the light guide. The internal frame also supports mounting of circuitry adjacent and coupled to the LCD.

  • Patent number: 5011198
    Abstract: An improved handle and latch assembly for a portable personal computer. The computer includes a cover. To open the cover, the user grasps the handle and pushes it a slight distance toward the computer. The handle is slideably coupled to the cover of the personal computer. A locking member is moveably disposed within the cover. A pair of locking hooks extend out of the cover and engage with slots in the keyboard section of the computer. When the handle is moved inward, it contacts the locking member and moves it, thereby releasing the hooks, and allowing the cover to be opened.

  • Patent number: 4959887
    Abstract: An improved hinge assembly for a personal computer system. The hinge is comprised of a tubular portion which is rigidly connected to the cover unit of the computer. A part of the tubular hinge is left open to form a passageway into the cover unit. The tubular portion rotates relative to the main body section of the computer. The tubular portion has a longitudinal section removed from near its mid-point, forming a gap. This gap is closed by a curved cover element. The cover element is held stationary with respect to the main body section of the computer. Thus, when the cover unit is opened, the tubular portion rotates relative to the cover element. A cable connecting the electrical components in the cover unit to the main body section passes through an opening in the curved cover element, is bent, travels through the tubular section, parallel to its central axis, is bent again and passes into the cover unit.
