Patent number: 10449965Abstract: A driver assistance device for a motor vehicle with a drive assembly, which can be connected to a drivetrain via a clutch that can be activated by an actuator. The clutch being a component of an electronically controlled clutch system, in which a clutch pedal sensor detects an actuation of a clutch pedal on the driver's side and in which an analysis unit determines, in a first control mode on the basis of the detected clutch pedal actuation, a clutch torque and actuates the clutch with a corresponding clutch signal. For an adjustment of the clutch response on the driver's side, the analysis unit is associated with an input unit, for the actuation of which, on the driver's side, it is possible to shift between the first control mode and at least one second control mode.Type: GrantFiled: November 8, 2016Date of Patent: October 22, 2019Assignee: AUDI AGInventors: Herbert Meyer, Andreas Schiergl, Clemens Burow

Patent number: 4178859Abstract: A door-like closure for passageways in high-risk high-security installations includes a multilayer protective plate which has a rather high resistance to mechanical, thermal and chemical damaging influences, but which can be rather easily damaged by the action of explosives. To reinforce the protective plate, a reinforcing grid is juxtaposed therewith at the major surface thereof which faces the interior of the installation so that, when an attempt is made to destroy the protective plate by explosives, the reinforcing grid not only will increase the resistance of the protective plate to damage but also will permit the explosive shockwave and the possible debris of the protective plate propelled thereby to penetrate through the apertures of the grid without causing any considerable damage to the grid. The apertures of the grid have such dimensions that an intruder will not be able to reach through the aperture into the interior of the installation to, for instance, manipulate the lock of the closure.Type: GrantFiled: August 30, 1977Date of Patent: December 18, 1979Assignee: Bochumer Eisenhutte Heintzmann GmbH & Co.Inventors: Rudolf Seiz, Heinz Eickhoff, Herbert Meyer, Dieter Steppke
