Patent number: 9863781Abstract: A yaw rate sensor (10) includes a movable mass structure (12) and a drive component (13) which is suitable for setting the movable mass structure (12) in motion (14), and an analysis component (15) which is suitable for detecting a response (40) of the movable mass structure (12) to a yaw rate (?). A method for functional testing of a yaw rate sensor (10) includes the following steps: driving a movable mass structure (12), feeding a test signal (42) into a quadrature control loop (44) at a feed point (48) of the quadrature control loop (44), feeding back a deflection (40) of the movable mass structure (12), detecting a measure of the feedback of the movable mass structure (12), and reading out the response signal (47) from the quadrature control loop (44).Type: GrantFiled: November 13, 2014Date of Patent: January 9, 2018Assignee: ROBERT BOSCH GMBHInventors: Wolfram Bauer, Johannes Classen, Rainer Willig, Matthias Meier, Burkhard Kuhlmann, Mathias Reimann, Ermin Esch, Hans-Dieter Schwarz, Michael Veith, Christoph Lang, Udo-Martin Gomez

Patent number: 7839227Abstract: An oscillating circuit includes an analog oscillation element. The oscillating circuit includes at least one analog-to-digital conversion device. A method is for operating an oscillating circuit, in which a mechanical oscillator oscillates at a natural frequency. The oscillation amplitude is measured and digitized. A digital control signal is generated from this with the aid of a digital amplitude controller. A driving signal is generated, in turn, from the digital control signal, the driving signal driving the mechanical oscillator with the aid of a drive unit. This control loop stabilizes the oscillation amplitude.Type: GrantFiled: December 9, 2005Date of Patent: November 23, 2010Assignee: Robert Bosch GmbHInventors: Hans-Dieter Schwarz, Arnd Gangei, Wolfram Bauer, Gerhard Wucher, Christoph Lang, Ermin Esch, Michael Veith, Thomas Mayer, Markus Brockmann

Patent number: 6340054Abstract: A plate heat exchanger, in particular an oil cooler for internal combustion engines, in a stacking mode of construction, provides conduits projecting toward one side for formation of feeding and drainage channels. Each conduit typically is provided with an edge bent inwards and running parallel to the base of the neighboring plate. The collar forming the conduit projects sufficiently far from the base of the plate that the edge projecting inwards can abut the base of the neighboring plate. This configuration reduces the heat exchange surface. To eliminate this problem, instead of collars with an encircling edge projecting only toward one side, collars projecting toward both sides are provided. Each of the collars is formed conically and engages, on stacking, into another of the collars. The collars are formed identically, but on plates which, when set on one another, are turned 180° with respect to the other, thus making simple soldering and simple handling possible.Type: GrantFiled: August 21, 2000Date of Patent: January 22, 2002Assignee: Behr GmbH & Co.Inventors: Gebhard Schwarz, Hans-Dieter Schwarz, Martin Wührl

Patent number: 4681157Abstract: A gas-tight crossflow heat exchanger consisting of a metal casing with two gas inlet nozzles and two gas outlet nozzles, at least one installation cover on the top of the casing, a block consisting of a number of ceramic heat-exchange elements mounted completely accurately in cuboid form with gas ducts arranged in layers one above the other and running at right angles to each other, four side surfaces having gas-duct openings, and the bottom and top surfaces being free of openings, the heat exchanger further consisting of thermal insulation between the metal casing and the block of ceramic heat-exchange elements.Type: GrantFiled: September 27, 1985Date of Patent: July 21, 1987Assignee: Uhde GmbHInventors: Hans-Dieter Schwarz, Friedrich W.

Patent number: 4129086Abstract: A torpedo has an acoustical system for detecting targets and directing the torpedo toward the target. An electric motor drives a cam that operates a switching arrangement that alternately changes the torpedo motor speed between fast and slow speeds. Upon sensing a target, the voltage applied to the motor driving the cam is increased to speed up the switching cycle and thereby shorten the duration of the slow and high speed intervals.Type: GrantFiled: December 4, 1967Date of Patent: December 12, 1978Inventor: Hans-Dieter Schwarz
