    摘要： An object tracking and motion control system includes a thermal marking unit such as a laser for inducing localized thermal indicia on objects. A thermal tracking unit, typically a micro electro mechanical system (MEMS) such as a two dimensional thermal sensing array, is positioned to measure movement of objects marked with localized thermal indicia. A motion control unit is connected to the thermal tracking unit to permit adjustment of motion of objects marked with induced localized thermal indicia based on their measured movement.

    摘要： A projective display system includes a light source (250), a display surface (282), and a two dimensional light modulator array (242) in an optical path between the light source (250) and the display surface (282). The two dimensional light modulator array (242) has a plurality of light modulators (244) arranged in rows to modulate light from the light source (250), with at least one row being susceptible to failure. To compensate for any failed rows, an optical element (270) redirects modulated light from presenting a first row (284) of virtual pixels on the display surface (282) to substantially occupy a second row (286) of virtual pixels on the display surface (282). In conjunction with various image processing techniques for deblurring, this permits partial or complete correction for faulty rows of light modulators.

    摘要： A valve array for supporting objects such as paper with controlled fluid flow is disclosed. Optional valve arrays can be used to controllably eject marking agents for marking or coating a paper or other suitable substrate. Each valve in the valve array has one or more flap elements (24) positioned in a valve chamber (16). These flap elements (24) are movable to alternatively block the fluid flow through valve chamber outlets with the aid of various catch mechanisms (34,36) for controllably latching the flap elements. The catch mechanisms (34,36) have a disabled state and an activated state for holding and allowing release of the flap elements. Once the catch mechanismS (34,36) are disabled, the flap elements are free to move to another position, provided they can overcome the mechanical fluid flow forces that tend to hold it in position. To counter and utilize such forces for moving the flap elements, an impulse mechanism kicks the flap element into the valve chamber, away from the catch mechanisms. Since the position of the flap elements is unstable, oscillations of the flap elements in the fluid flow will eventually bring the flap element into catchment range of another catch mechanism in an activated state.

    摘要： A valve array system including microelectromechanical valves (27,37,43) embedded in a dielectric substrate (51-56) is disclosed. These microelectromechanical valves (27,37,43) can be batch fabricated using resin impregnated dielectric laminates having photolithographically formed circuitry for electrical connections. Movable components of valves, including electromagnetic or electrostatically actuated membranes, flaps, or beams, can be formed from laminate material using sacrifice layers and etching.
