    摘要： 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.

    摘要： A bistable valve useful for paper handling applications is disclosed. The valve can be batch fabricated in two dimensional valve arrays, with each valve in the array being controlled by passive matrix addressing. Typically, each valve includes a valve housing having an aperture plate defining an aperture therethrough, and an opposing plate positioned in spaced apart relationship to the aperture plate. A flexible film or strip is attached at its first end to the aperture plate and at its second end to the opposing plate. Valve action is provided by use of at least two switching electrodes for moving the flexible film between an aperture blocking position and an aperture open position, with at least one of the switching electrodes positioned adjacent to the aperture plate and at least one of the switching electrodes positioned adjacent to the opposing plate. To reduce unswitched movement when the switching electrode bias is reduced or not present, at least two electrostatic or mechanical catches are used.

    摘要： A sensor system for measuring physical properties of a sheet. In one embodiment, the sensor system measures paper curl and thickness using two sensors, each of which includes a member, a base, and measurement circuit. The two members are positioned in opposition to each other and both contact the sheet as it passes between them. Each member is coupled to a base, which includes a measurement circuit. Each measurement circuit measures the displacement of its associated member. In another embodiment, 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 of paper 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.

    摘要： Apparatus and method for sensing the position, size, shape and location orientation of one or more objects in two dimensions. The position sensor uses arrays of light sensors mounted on a substrate. When an object passes in proximity to the light sensors light energy from a plurality of light sources is either reflected from the object to the light sensors, or is emitted directly to the light sensors. The light energy is then converted to individual signals and transmitted through circuit traces in a printed circuit board to a local controller. The information may then be processed to determine the size, position, shape and location orientation of an object.

    摘要： A roller assembly is provided with openings in its outer surface for selective communication with a source of vacuum or a positive pressure. The openings may be angled along the roller rotational axis to impart a component of velocity to the paper perpendicular to the tangential roller surface velocity. Additionally, by selectively connecting the openings with sources of pressure and vacuum, enhanced paper alignment is achieved, multiple paper feeds eliminated, transitions between different velocities of rollers completed, or paper reverted so that printing can be achieved on first and second sides thereof.
