Abstract: A flexible multimedia presentation system is configured to be releasably secured to a portable personal computer to provide additional features, such as a PCMCIA interface, a port replicator and other options. The system is configured to enable the unit to be rather easily transported as a unit. A retractable handle is provided which further facilitates transport of the unit. In order to provide enhanced flexibility of the flexible multimedia presentation system, the system includes a PCMCIA interface, as well as replicates the various I/O ports on the rear of the portable personal computer. By replicating the I/O ports on the portable personal computer, external I/O devices, such as an external monitor, keyboard, mouse and printer can be used when the portable personal computer is docked to the flexible multimedia presentation system.

Abstract: A portable presentation system includes a portable personal computer with a removable LCD and a stand assembly for carrying the LCD in a detached position to enable the LCD to be viewed when detached from the portable personal computer. In accordance with an important aspect of the invention, the LCD display is formed with a hinge which enables the viewing angle of the display to be fully adjustable in both a detached and attached position. The LCD display system also includes a latching mechanism which enables the display to be latched to the computer housing in all positions, thus preventing inadvertent removal and perhaps damage to the display. The stand assembly includes a base for carrying the LCD in a detached position and enabling the LCD display to be latched thereto in all viewing angle positions while enabling the viewing angle to be varied. The stand also includes a connector that is adapted to mate with a connector on the LCD display.

Abstract: A locking hinge for a printed circuit board includes a pair of molded end pieces defining guide tracks cooperating with tabs on one edge of the printed circuit board for permitting confined pivotal movement thereof between two positions. Slots are formed in the guide tracks for engagement with the tabs by lateral movement of the board. When the tabs are engaged with the slots, the board is restricted from pivotal movement. Stops are formed in the end pieces adjacent to the slots to positively define the two positions. Ports are provided to permit entry and removal of the printed circuit board when in an intermediate position.
