Patent number: 11619489Abstract: A method for visualizing an inclination of a motor vehicle in the motor vehicle, in which the inclination of the motor vehicle is measured and made visible in the interior of the motor vehicle. The inclination is made visible by interior lighting of the motor vehicle. At least one virtual plane is formed, which intersects the motor vehicle horizontally when the latter is in a horizontal position and serves as a reference plane for displaying the inclination. Changes in the inclination of the motor vehicle are modeled dynamically by the interior lighting by the sequential and/or parallel activation of illuminants of the interior lighting.Type: GrantFiled: April 16, 2021Date of Patent: April 4, 2023Assignee: Volkswagen AktiengesellschaftInventors: Sascha Ziebart, André Heinrichs

Publication number: 20220402430Abstract: Technologies and techniques for controlling the interior lighting of a vehicle. Multiple lighting units are distributed in the interior of the vehicle, and each of the lighting units is assigned at least two color zones. Arrangement profiles for arranging the at least two color zones in the interior of the vehicle are displayed on a display and operating device, and a user selection of one of the arrangement profiles is detected. A color selection by the user is detected for each of the at least two color zones via a respective operating element displayed on the display and operating device, and a color is set for each lighting unit by a controller according to the selected arrangement profile and the colors selected for the at least two color zones. The invention also relates to a device for controlling the interior lighting of a vehicle.Type: ApplicationFiled: October 13, 2020Publication date: December 22, 2022Inventors: Richard Knipp, André Heinrichs, Janine Bretz, Margret Siegmund

Patent number: 7757714Abstract: A two-stage servo-valve has a first stage in which four flow resistances are arranged in a bridge circuit. At least one of the flow resistances is variable, and two opposite switching points of the bridge circuit are connected to an air inlet and to an air outlet respectively. A differential pressure of variable size and sign is provided between the two other switching points. The servo-valve also has a second stage in which a control piston which can be actuated by the differential pressure is arranged and controls a three-way valve. In order to enable the current position of a process valve driven by the servo-valve to be maintained by the most simple means in the event of a power failure, the switching points which provide the differential pressure are interconnected by a magnetic valve which is closed in the driven state and open in the unconnected state, thus pneumatically interconnecting the switching points.Type: GrantFiled: October 5, 2005Date of Patent: July 20, 2010Assignee: Siemens AktiengesellschaftInventor: Andre-Heinrich Meinhof

Publication number: 20090260700Abstract: There is described a 3-port directional control valve having a first valve chamber, a second valve chamber and a third valve chamber, wherein a first fluid passage, which can be closed off by means of a first adjustable valve body, is provided between the first valve chamber and the second valve chamber, and a second fluid passage, which can be closed off by means of a second adjustable valve body, is provided between the second valve chamber and the third valve chamber. The first valve body and the second valve body are arranged on an actuating element which is mounted so as to be rotatable about at least one rotational axis, so that the adjusting movements of the valve bodies take place in opposition to one another. A diaphragm is arranged between the valve bodies, and the actuating element, herein the effective area of the diaphragm is matched to the effective cross section of the respective valve body for the purpose of force equalization.Type: ApplicationFiled: July 25, 2006Publication date: October 22, 2009Inventor: Andre-Heinrich Meinhof

Patent number: 7024924Abstract: A method and arrangement for determination of the sharpness of chopping blades of a field chopper during chopping includes the steps of measuring, at least at two points in time, a characteristic parameter of the operating oscillation of a component of the chopping unit. Each such measurement obtains the oscillation fractions of at least two frequency bands of the measured signal or its peak, with the ratio between the two measurements being evaluated to generate a signal, when a certain deviation is determined between the initial measurement and the current measurement, which is indicative of the need to sharpen the chopping blades and the counterblade. The sharpening process can then be automatically initiated.Type: GrantFiled: July 24, 2003Date of Patent: April 11, 2006Assignee: Deere & CompanyInventors: André Heinrich, Matthias Grimsel, Gerd Bernhardt

Patent number: 6695282Abstract: A positioner for a valve that is actuated by means of a drive. The positioner includes a locator (9) and a control unit (13). The locator (9) detects the actual position of an actuator (7). The control unit (13) compares the actual position with a predefined desired position, and generates an actuating signal. A magnet (18) having a magnetoresistive sensor, preferably a GMR sensor, is provided as the locator. The locator (9) is less susceptible to dirt and less prone to wear and tear than a conventional slide potentiometer. The positioner is thus less fault-prone.Type: GrantFiled: October 4, 2002Date of Patent: February 24, 2004Assignee: Siemens AktiengesellschaftInventors: Wolfgang Clemens, Klaus-Dieter Fiebelkorn, Gerhard Klebert, Klaus Ludwig, Andre-Heinrich Meinhof, Holger Schmaedicke

Patent number: 6688971Abstract: A chopper arrangement for a harvesting machine comprises a body that is rotated in a predominantly vertical axis of rotation. The body is provided with a plurality of radially extending knives that are axially distributed along the body. The knives have radially outer ends that are arranged in a conical shape. In this way the knives at the first end having a smallest radial extension are rotated at a slower circumferential speed than knives having a larger radial extension.Type: GrantFiled: December 6, 2001Date of Patent: February 10, 2004Assignee: Deere & CompanyInventors: Martin Büermann, Walter Hirsch, Adolf Belter, Gerd Bernhardt, Siegfried Firus, André Heinrich
