Abstract: A display and scanning assembly is disclosed wherein light reflected from or transmitted through an image being scanned is transmitted to an optical sensor through an optical shutter assembly via a light guide assembly. The optical shutter assembly is made substantially opaque except for one or more selected optical shutter elements that are made substantially transparent or opened. Light is then reflected from or transmitted through the medium containing the image to be scanned through substantially transparent shutter element or elements and transmitted to the optical sensor via a light guide assembly. The image may then be scanned by advancing selection of shutter element or elements that are opened across the medium.

Abstract: An orientation sensor includes variable resistance elements within the sensor, the variable resistance elements forming an electric circuit with a conductive ball or drop of conductive material. The resistance of the electric circuit uniquely identifies the orientation of the apparatus. A method of determining the orientation of an apparatus includes measuring the resistance of a circuit completed between two conductive members in the apparatus, and determining the position of a freely movable conductive member in the apparatus from the measured resistance.

The image may then be scanned by advancing selection of shutter element or elements that are opened across the medium. The optical scanning assembly may further be capable of functioning as a display assembly wherein color components for each display element or pixel of the display assembly are premixed so that the display elements provide a true color instead of separate red, green and blue components of that color.

Abstract: A display assembly is provided with individually actuateable shutter row elements. Selected ones of the shutter row elements are actuated in a predetermined sequence, blocking and allowing pulsed of light transmitted via a light guide assembly. The shutter row elements sequentially illuminate selected groups of display elements so that the display elements provide a true color instead of separate red, green and blue components of that color. In this manner, the display assembly of the present invention is capable of providing a higher fidelity image than is possible using existing display technologies.

Abstract: A media scanner scans information disposed on a media such as a business card or envelope. The media scanner requires no moving parts and may be incorporated in a portable, hand held, battery powered information handling system such as an electronic address book or personal digital assistant. The scanner includes a scanning element such as a linear CCD element for scanning the information stored on the medium, which is converted into a graphical image or text file. As the medium is fed past the scanning element, a detector detects the movement of the medium as the medium is fed through the scanner. Any variation of the movement of the medium, for example due to inconsistent movement or pausing caused by hand scanning, etc., is detected by detector, and scanning is executed according to the detected movement so that optimal scanning is maintained.

Abstract: A display system, display device and add-on for a display device are disclosed to provide for viewing a three-dimensional image using polarization. The image is separated into first eye and second eye components. In one embodiment, a system comprises a computer-driven display device and a pair of viewing glasses. The display device is adapted to display the first eye and second eye components in alternating refreshes of the display device, the alternating refreshes polarized substantially perpendicular to one another. The pair of viewing glasses has two lenses. Each lens is polarized substantially particular on one another, in accordance with the alternating refreshes.

Abstract: Triple-buffering video memory in a computer graphics controller improves the quality of full-motion video converted for display on a computer monitor. Buffer size, organization, and access cycles prevent converted data representing a new video frame from overwriting a buffer in memory that contains converted data representing a video frame currently being displayed. The access cycles also ensure all data representing a video frame is displayed. The video memory is partitioned into three logical buffers to hold the converted data, the buffers are arranged in a logical ring sequence for read and write access, and the data in a buffer is repeatedly read until the next buffer in the sequence is full of data and ready to be read. In addition, the buffering is adaptable to different resolutions as the size of the buffers is determined by the value of the resolution each time the video conversion is initiated.
