Patent ID: 6839957

Claim:
A displacement unit for a manipulation system, which comprises (a) components which are adjustable relative to each other, (b) a drive actuated by pressure fluid for adjusting the components, the drive having (1) an outer surface, (c) a guiding device for one of the components, (d) a control unit mounted on the outer surface of the drive, the control unit having (1) at least one pressure fluid control valve connected to the drive for actuating the drive by the pressure fluid, (2) a control module cooperating with the at least one pressure fluid control valve and comprising a logic unit which processes logic and bus information in order to determine and monitor the position of a respective one of the adjustable components and displacement parameters of the displacement unit, the control module being connectable to a central control unit by an interface, and the at least one pressure fluid control valve and the control module being mounted directly on the outer surface of the drive, (3) a display element, (e) at least one first signaling and monitoring element for detecting the position of the adjustable component during the operation of the displacement unit, the at least one first signaling and monitoring element being disposed in the component; and (f) at least one second signaling and monitoring element for detecting and monitoring displacement parameters during the operation of the displacement unit, and both first and second signaling and monitoring elements being connected to the control unit or central control unit for transmitting actual values of position and displacement parameter to the control unit or central control unit.
