The hydraulic tensioner has a pot-shaped housing in which a piston is elastically suspended against a traction element and guided for longitudinal displacement. A damping device forms a leak gap which serves to damp adjusting movements of the piston. The leak gap is defined by a bushing which is inserted into the housing and, at the same time, guides the piston. During an adjusting movement of the piston towards a pressure chamber filled with a hydraulic fluid, a fractional quantity of the hydraulic fluid is displaced via the leak gap. An adjusting movement of the piston in the opposite direction causes a re-flow of the hydraulic fluid via a one-way valve arranged in the housing.02-25-2010

The control circuit receives from the power management unit at least a first control signal for switching OFF the electrical energy in said primary power path, said power supply unit entering a very low power mode (“Power-down” mode) when said first control signal is set to OFF so that the converter is not supplied anymore. The power management unit is arranged such that, in said very low power mode, it can receive or generate at least a wake-up signal and set to ON said first control signal in response to said wake-up signal for supplying again said primary and secondary parts of the converter.01-14-2010

20080307711Vehicle Door with a Variable Latching Function - A vehicle door with a variable latching function which holds the vehicle door in a desired latched position by applying a latching torque using a controllable damper is described. An evaluation and control unit detects the desired latched positions by evaluating an instantaneous door movement sensed by a sensor system and actuates the damper using an actuator element. The evaluation and control unit releases the latched position after a corresponding activation is detected. The variable latching function acts on the vehicle door within a functional region which extends to a predefined opening region between a first opening angle and a maximum opening angle when the vehicle door drops below a predefined speed or comes to a standstill within the functional region.12-18-2008

20100024574Force Sensor and Method for Detecting At Least One Force Component - A force sensor for detecting at least a force acting in a longitudinal direction of a catheter or guide wire, the force sensor comprising a force pick-up for detecting the force, wherein the force pick-up comprises: a base body with an end face, wherein the base body includes at least one cutout, wherein the cutout causes an asymmetry of the base body relative to the longitudinal direction of the catheter or guide wire upon flexing of the base body upon force F02-04-2010
20100307265Force Sensor for the Detection of a Force Vector - The invention makes it possible to determine a force vector that is applied to a tip of a minimally invasive surgical instrument. The force acts upon the housing, is directed to the base, and causes a deformation there in special beam structures. Said deformation is detected by means of tension-sensitive/extension-sensitive resistors whose changes are a measure for the applied force vector. The inventive measuring element comprises special mounting elements so as to be integrated into tube-type instruments such as guiding wires, fastening zones for additional components, an overload protection, and a head shape that is adapted to the treatment process.12-09-2010
