Abstract: A clutch actuator and to a method for the control thereof. The actuator actuates a multi-disk clutch, and to do so has actuator modules. The number of which corresponds to the number of the friction clutches. The modules have separate control units and electric motors, which are controlled by the control units and act on the friction clutches by a disengaging mechanism. In order to counter block the partial drive trains disposed downstream of the friction clutches, particularly automatically closed friction clutches during a malfunction of an actuator module, the actuator modules are connected among each other to a data line, which allows monitoring of the actuator modules and counter-measures.

Abstract: A method of providing a linear drive with an axially play-free entrainment connection between at least one linearly travelling rod (5) and a guide unit able to be moved parallel thereto. Between a coupling member (26), projecting to the fore of the rod (5), of the guide unit and the terminal face (27) of the rod (5) adhesive (34) is applied and then the components are so screwed together that athwart the direction of displacement relative motion is still possible. Then the entire unit is shifted between its two terminal positions even prior to curing of the adhesive (34), the components then aligning themselves. After the adhesive is cured the screw connection is finally drawn tight.

Disclosed are systems and processes for combining electrically conductive and absorptive materials to improve EMI shielding effectiveness. In one embodiment, an absorptive material is combined with the conducting material forming a composite. In another embodiment, absorptive material is combined with electrically conductive material and selectively applied to a substrate, such as a plastic enclosure, to suppress EMI incident upon the substrate, thereby reducing the susceptibility of electronics contained within across a broad frequency range.
