Abstract: A system (140) for measuring the mass of a sheet (150) of material including an actuator (141), a position sensing system (42), and a tactile sensor system (200). The actuator (141) imparts a known force to the sheet (150), moving it through to the position sensing system (142), which measures the sheet velocity at various points. Afterward, the sheet (150) moves through the tactile sensor system (200), which determines the coefficient of friction of the sheet. Given these quantities, a controller can determine the mass of the sheet (150), which can be used alter the performance of paper handling devices in a reproductive machine. A second embodiment (Fig. 6) of the mass measuring system includes an actuator, a position sensing system, and a subsystem for eliminating friction. The actuator applies a force to a sheet to move it into and through the subsystem. The position sensing system incorporated in the subsystem senses the acceleration of the sheet. Given this quantity, a controller can determine the mass of the sheet.

Abstract: A PC board actuator (10) that emulates a muscle fiber includes a first pressure source (16), a second pressure source (15) lower than the first source, at least one expansion chamber (24) alternately communicating with the first and second pressure sources, first (18) and second (20) valves mounted with the PC board (13) that open and close the chamber with respect to the first and second pressure sources, and an actuator member (28) interacting with the expansion chamber to apply a force to the object (35). The actuator is preferably formed using planar batch technology and the valves preferably comprise electrically controllable flap valves mounted on the PC board. Alternatively, the actuator includes antagonistically arranged expansion chambers (24,25) that operatively apply reciprocating forces to the object. In other embodiments, the actuator includes plural expansion chambers arranged in series or in parallel in order to increase the overall extent of attainable displacement or to amplify the force generated by the actuator.

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: Es werden Verfahren zum Höhenausgleich von Tinte auf Substraten und Vorrichtungen, die für das Drucken geeignet sind, bereitgestellt. Eine anschauliche Ausführungsform der Verfahren umfasst: Beaufschlagen von Tinte, die auf einer Oberfläche eines por von mindestens einer Strahlungsenergiequelle abgegeben wird. Die Strahlung erwärmt die Tinte auf zumindest eine Viskositätsschwellwerttemperatur der Tinte, so dass die Tinte lateral auf der Oberfläche fließen kann, um einen Höhenausgleich der Tinte zu erzeugen. Die Tinte wird ausreichend schnell erwärmt, so dass eine Wärmeübertragung von der Tinte auf das Substrat klein ist während des Höhenausgleichs, so dass Tinte an der Substratgrenzfläche auf eine Temperatur unterhalb der Viskositätsschwellwerttemperatur gekühlt wird, wodurch ein ausgeprägtes Eindringen der Tinte in das Substrat verhindert wird.
