    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.
