    摘要： A printer includes an inkjet pen to eject ink drops for printing on the surface of a sheet, a carriage mounted to carry the pen back and forth on the sheet, and a skid-like spacer to ride upon the printed surface. The spacer maintains a preselected spacing between the pen and the printed surface and, also, maintains paper flatness at the localized area of printing.

    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.

The method includes providing an emulsion including water and a discontinuous coating phase having a copolymer dissolved in a monomer mix; providing a pigment dispersion including water, surfactant, and pigments dispersed therein; mixing the emulsion with the pigment dispersion under high shear conditions such that the coating phase is deposited on the pigments, thereby forming polymer and monomer coated pigments; and polymerizing the monomers at the surface of the polymer and monomer coated pigments to form polymer-encapsulated pigments dispersed in a fluid medium.

    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.
