Abstract: A computer system has a power-down mode to conserve energy. The computer system includes a speech transducer for capturing speech; a low-energy consuming power-up indicator coupled to said speech transducer, said power-up indicator detecting speech directed at said speech transducer and asserting a wake-up signal to a powered-down processor; and a voice recognizer coupled to said speech transducer and said wake-up signal, said voice recognizer waking up from the power-down mode when said wake-up signal is asserted.

Abstract: The present invention provides a graphical data entry system for accepting and processing hand sketches and writings such that the user can quickly specify graphical objects in a drawing on a hand-held, mobile computer with a relatively compact screen. A viewing glass is provided by the graphical data entry system which enables the user to pan and zoom into a specific display region of the drawing. An object classification and recognition capability is provided to allow the present invention to recognize objects being sketched by the user and to convert the hand sketches into computer aided design (CAD)-like drawings. Further, the present invention integrates speech recognition and keyboard data entry to provide a user friendly computer system. Additionally, the graphical data entry system of the present invention can be used in conjunction with a camera to annotate pictures taken with the camera.

Abstract: A portable computer system manages data conveniently for a user. The system has a processor, a program storage device coupled to the processor, an input recognizer adapted to receive data from the user, and a computer readable code embodied in the program storage device for storing and processing the data.

Abstract: An adjustable height and position retainer for releasable retaining a printed circuit card in a circuit card edge connector. The retainer includes an elongated base member for attachment to the side of a circuit card edge connector, an elongated retaining post, and a clamp assembly slideably attached to the retaining post and positionable at any selected position along the length of the retaining post. The retaining post is slideably attached to the base member such that the post is secured in an orthogonal relationship with the circuit card edge connector and parallel with a circuit card installed into the edge connector, yet the retaining post is positionable at any selected position along the length of the base member. The clamp assembly includes an extrusion which holds the top edge of a printed circuit card installed into the circuit card edge connector.
