Abstract: A portable or stationary electronic device equipped with a typing keyboard, such as a notebook or desktop personal computer or screen-phone, with a retractable palmrest in accordance with the present invention includes a platform, circuitry, a display, a keyboard, and the retractable palmrest. The palmrest provides ergonomic benefit for typing and a suitable location for a full-size track pad (mouse pad) pointing device, mouse buttons and other low-profile peripheral devices. By retracting, and optionally folding, it reduces the size of the electronic device during storage or transport. The platform includes a front surface, opposing side surfaces, a back surface, and a top surface. The circuitry is connected to the platform. Keys forming a keyboard are connected to the top surface of the platform and are coupled to the circuitry along with the display.

Abstract: An expandable keyboard in accordance with the present invention provides a full-size or expanded keyboard for typing which folds to minimize size during transport or storage, and can be converted to substantially twice its folded length for use. Its use of sliding segments permits a straight hinge line for folding. Its operating mechanism supports a large number of electrical interconnections between the hinged wing section or sections and the central platform, and provides for straight-line engagement as well as environmental and ESD protection of the mating electrical connectors. It permits the operation of removable modules such as PCMCIA cards or fixed circuitry such as speakers or keypads in the wing section or sections in both their open and closed positions. It includes a central keyboard assembly and a first assembly comprising a first segment and a first wing. The central keyboard assembly includes one or more keys and a platform.

Abstract: An electronic product, such as a personal computer or electronic organizer with an open-surfaced receptacle or slot is described. An electronic product incorporating such a receptacle is able to accommodate an insertable electronic module, such as a PCMCIA card, that is thicker than could be incorporated in the receptacle if a portion of the inserted module were not permitted to protrude through the receptacle along the open surface. One embodiment of the invention includes a display, a platform, circuitry, a keyboard, the receptacle, an electrical connector in the receptacle, protective sliding shutters and a door. The platform includes at least two opposing surfaces and at least one side. The inserted card is connected to the circuitry in the platform via the electrical connector located in the receptacle. The keyboard is connected to one of the opposing surfaces and is also coupled to the circuitry.
