Abstract: A scanning backlight for a stereoscopic 3D liquid crystal display apparatus includes a light guide having a first side and a second side opposite the first side, and having a first surface extending between the first and second sides and a second surface opposite the first surface. The first surface substantially re-directs light and the second surface substantially transmits light. A plurality of first light sources are arranged along the first side of the light guide for transmitting light into the light guide from the first side and a plurality of second light sources are arranged along the second side of the light guide for transmitting light into the light guide from the second side.

Abstract: Various methods and fluid delivery systems are described for printing digitally imaged signs. One method of applying pigmented material to a print medium involves using a fluid delivery system to coat at least a portion of an exterior surface of a cable with a pigmented material and then placing the coated portion of the cable in close proximity to the print medium. An air stream is then directed at the portion of the cable coated with the pigmented material such that a the pigmented material is removed from the exterior surface of the cable and is deposited onto the print medium.

Abstract: A printer for digital printing in which ink is deposited in metered amounts on a substrate. The printer includes a wheel rotatable by a shaft of a motor, an idler disposed in a paint reservoir, and a segment of wire disposed around the wheel and the idler. A computer controls movement of the wire by controlling the rotation of the wheel. As the motor rotates the wheel, ink contained within the paint reservoir coats the wire and is drawn by the wire in front of an air stream, which pulls the ink from the wire and carries it toward the substrate. The wire has alternatively hydrophilic and hydrophobic areas, causing the ink to form droplets on the wire for printing them as discrete pixels onto the substrate.

Abstract: The present invention provides a digitizer that includes a transparent overlay that incorporates a transparent material pattern that is coded to be indicative of position and detection device configured to read the pattern for determining position information. The transparent material of the coded pattern can include infrared sensitive materials, for example. Transparent digitizers of the present invention may be useful in applications such as Tablet PC mobile computers.
