    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 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 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 positioned in a valve chamber. These flap elements are movable to alternatively block the fluid flow through valve chamber outlets with the aid of various catch mechanisms for controllably latching the flap elements. The catch mechanisms have a disabled state and an activated state for holding and allowing release of the flap elements. Once the catch mechanism 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 for redirecting fluid flow has a valve chamber supporting fluid flow, with the valve chamber having an inlet, a first outlet, and a second outlet. The valve chamber can be closed or partially open. The flap element is movable to alternatively block the first outlet and the second outlet. In or immediately adjacent to the valve chamber are opposing first and a second catch mechanisms for controllably latching the flap element to block respectively the first outlet and the second outlet. The first and second catch mechanisms have a disabled state and an activated state for holding and allowing release of the flap element. Once the first or second catch mechanism is disabled, the flap element is free to move to another position, provided it can overcome the mechanical fluid flow forces that tend to hold it in position. To counter and utilize such forces for moving the flap element, an impulse mechanism kicks the flap element into the valve chamber, away from one of the first and second catch mechanisms, after one of the first and second catch mechanisms is controllably brought into the disabled state. Since the flap element is unstable, oscillations of the flap element in the fluid flow will eventually bring the flap element into catchment range of one of the first and second catch mechanisms in an activated state.
