摘要： Method and apparatus for determining the distance a sheet of paper, or other reflective or transmissive substrate material with a suitable, approximately planar surface, has moved in a given direction. The substrate is illuminated by reflection or transmission of light at non-normal incidence, and a linear array of N uniformly spaced light sensors is provide to receive and sense light issuing from the illuminated substrate. This produces a first or reference array of light signal strengths s.sub.1 (k) (k=1,2, . . . , N). The substrate is then moved in the given direction, and a second array of signal strengths s.sub.2 (k) (k=1, 2, . . . , N) is produced. A cross-correlation function C(K), formed from consecutive portions of the first and second light signal strength arrays, is then examined to determine the distance the substrate has moved in the given direction. A maximum in the cross-correlation function C(K) at K=K.sub.0 corresponds to displacement of the substrate in the given direction by a distance approximately equal to (MF)(K.sub.0 -i)d, where i is selected positive integer determined by the initial position of the substrate, the distance d is determined from the known spacing of the light sensors, and MF is the system optical magnification factor. The cross-correlation function can be computed with uniform or non-uniform weights in the sum. This one-dimensional approach is extended to determining the vector of two-dimensional movement of the substrate, including translation, rotation and scaling, in a two-dimensional plane.

摘要： A desktop printing system for use with microprocessor-based computers includes the modular combination of a color printer and a monochrome text printer. Preferably, the color printer is of the type which prints color graphics incrementally and the text printer is of the type which prints monochrome text continuously. In operation, printing information is segregated into color and text components, and the color printer is controlled to print only color components while the text printer is controlled to print only monochrome text components.

摘要： Molecular systems are provided for electric field activated switches, such as a crossed-wire device or a pair of electrodes to which the molecular system is linked by linking moieties. The crossed-wire device comprises a pair of crossed wires that form a junction where one wire crosses another at an angle other than zero degrees and at least one connector species connecting the pair of crossed wires in the junction. The connector species comprises the molecular system, which has an electric field induced band gap change, and thus a change in its electrical conductivity, that occurs via one of the following mechanisms: (1) molecular conformation change; (2) change of extended conjugation via chemical bonding change to change the band gap; or (3) molecular folding or stretching. Nanometer-scale reversible electronic switches are thus provided that can be assembled easily to make cross-bar circuits, which provide memory, logic, and communication functions.

摘要： The present invention provides a printer and media solution that is conducive to briefcase-compatible compactness, battery operation, and media reuse. The printer consists of a low power, electrode array that images the surface of a paper-like, rewritable sheet. The sheet is responsive to pixel-sized electric fields produced by each electrode, resulting in a pixel array that is imaged in response to field polarity. The sheet is coated with a rewritable colorant that is a highly energy efficient, bistable, bi-modal molecular layer, requiring energy only to change an image, not to hold or illuminate it.
