    Abstract: A fluid transport system for moving flexible objects includes a conveyor configured to direct fluid flow against opposite sides of flexible objects. A sensor unit senses motion state of flexible objects, and a motion analysis unit is connected to the sensor unit to calculate relative or absolute movement of flexible objects based on the motion state. Overall movement, position, velocity, and orientation of flexible objects can be determined, as well as internal movement of the object attributable to flexure or edge curling. A motion control unit is connected to the motion analysis unit to modify fluid flow directed against opposite sides of flexible objects, accurately adjusting motion of flexible objects.

    Abstract: A paper handling system (110) for air mediated transport of sheets or pages of paper (112) is disclosed. Microelectromechanical valves and sensors are embedded in a dielectric substrate (Fig.1) for tracking and controlling paper transport. These microelectromechanical systems can be batch fabricated using resin impregnated dielectric laminates having photolithographically formed circuitry for electrical connections. Use of high speed sensor (140) and valve control systems (152) permit dynamic adjustments to paper trajectory during paper transport.

    Abstract: 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 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.

    Abstract: A sensor system (100a) for measuring physical properties of a sheet (116). In one embodiment, the sensor system measures paper curl and thickness using two sensors, each of which includes a member (112), a base (114), and measurement circuit. The two members (112) are positioned in opposition to each other and both contact the sheet (116) as it passes between them. Each member is coupled to a base (114), which includes a measurement circuit. Each measurement circuit measures the displacement of its associated member (112). In another embodiment (Fig. 4), the sensor system measures stiffness and curl using two pairs of opposed sensors. In yet another embodiment, the sensor system measures thermal diffusivity of a sheet using three sensors, one of which includes a heater for heating the sheet of paper and the other two sensors include thermocouples in contact with the sheet of paper for sensing the heat of the paper.

    Abstract: The display system includes a light source (350) and a display surface. A two dimensional light modulator array (342) is arranged in the optical path between the light source and the display surface. The light modulator array includes several light modulators arranged in rows to modulate light from the light source. A redundant light modulator array (385) having several light modulators arranged in rows modulates the light from the light source. A mirror (370) is positioned to selectively direct light incident on the redundant array towards the display surface to substitute for a failed row of light modulators in the two dimensional array.

    Abstract: PROBLEM TO BE SOLVED: To facilitate the manufacture by forming first and second laminate layers of the dielectric base material impregnated in the resin, and arranging a second opening to be partially overlapped with a first opening in forming each opening to demarcate a tapered conduit. SOLUTION: A micro device support system 10 comprises a plurality of micro devices including an array 26, a valve 27, and a sensor 28 of air conduits. A conveyor includes laminates 51-56 consisting of resin-impregnated fiber glasses which are adhered to each other, and the air conduits 26 are provided with a plurality of air conduits 31-34, and in the conduits 31-34, an opening is formed in each laminate, and forming the whole tapering by partially overlapping the opening with the adjacent opening. The valve 27 controls the fluid flow from a fluid pressure source 121 and applies the force to an object to be carried, and includes a flap valve 37 and a solenoid valve embedded in a channel 42.

    Abstract: PROBLEM TO BE SOLVED: To provide a system for monitoring and controlling the action of a structural element. SOLUTION: A system 10 which detects vibration in a printer composing element, a mechanical device, and structural members of a building or a large structure and damps the vibration as occasion demands has a plurality of optical beam detectors 22 to generate a signal corresponding to the position of a reference optical beam 32. The optical beam detector 22 is partially transparent so that an optical beam may pass through the detector, and a plurality of detectors can thereby use the same reference optical beam. The detector is attached to a structural member 12 sensitive to the vibration, and the detected motion of the optical beam detector to the partially transparent optical beam detector corresponds to the motion of the structural member sensitive to the vibration. The detected vibration can be controlled or clamped at real time using a motion control unit 38 connected to the detector.
