Patent number: 6752017Abstract: A yaw-rate sensor is proposed having a first and a second Coriolis element (100, 200) which are arranged side-by-side above a surface (1) of a substrate. The Coriolis elements (100, 200) are induced to oscillate parallel to a first axis. Due to a Coriolis force, the Coriolis elements (100, 200) are deflected in a second axis which is perpendicular to the first axis. The first and second Coriolis elements (100, 200) are coupled by a spring (52) which is designed to be yielding in the first and in the second axis. Thus, the frequencies of the oscillations in the two axes are developed differently for the in-phase and antiphase oscillation.Type: GrantFiled: March 19, 2003Date of Patent: June 22, 2004Assignee: Robert Bosch GmbHInventors: Rainer Willig, Andreas Thomae, Burkhard Kuhlmann, Joerg Hauer, Udo Martin Gomez, Siegbert Goetz, Christian Doering, Michael Fehrenbach, Wolfram Bauer, Udo Bischof, Reinhard Neul, Karsten Funk, Markus Lutz, Gerhard Wucher, Jochen Franz

Patent number: 6705164Abstract: A yaw-rate sensor including a first and a second Coriolis element that are arranged side-by-side above a surface of a substrate. The Coriolis elements are induced to oscillate parallel to a first axis Y. Due to a Coriolis force, the Coriolis elements are deflected in a second axis X which is perpendicular to the first axis Y. The oscillations of the first and second Coriolis elements occur in phase opposition to each other on paths which, without the effect of a Coriolis force, are two straight lines parallel to each other.Type: GrantFiled: March 19, 2003Date of Patent: March 16, 2004Assignee: Robert Bosch GmbHInventors: Rainer Willig, Andreas Thomae, Burkhard Kuhlmann, Joerg Hauer, Udo-Martin Gomez, Siegbert Goetz, Christian Doering, Michael Fehrenbach, Wolfram Bauer, Udo Bischof, Reinhard Neul, Karsten Funk, Markus Lutz, Gerhard Wucher, Jochen Franz

Patent number: 6691571Abstract: An rate-of-rotation sensor having a Coriolis element, which is arranged over a surface of a substrate, is described. The Coriolis element is induced to oscillate in parallel to a first axis. In response to a Coriolis force, the Coriolis element is deflected in a second axis, which is perpendicular to the first axis. A proof element is provided to prove the deflection.Type: GrantFiled: May 29, 2003Date of Patent: February 17, 2004Assignee: Robert Bosch GmbHInventors: Rainer Willig, Andreas Thomae, Burkhard Kuhlmann, Joerg Hauer, Udo-Martin Gomez, Siegbert Goetz, Christian Doering, Michael Fehrenbach, Wolfram Bauer, Udo Bischof, Reinhard Neul, Karsten Funk, Markus Lutz, Gerhard Wucher, Jochen Franz

Patent number: 5866822Abstract: A device for measuring various fluid pressures, the device includes a sensor plate which has fastening holes, which are distributed in matrixlike fashion over the sensor plate. Measuring diaphragms, which form end walls of blind bores in the sensor plate, are located between the fastening holes. Through fluid conduits of a hydraulic block to which the sensor plate can be secured, the measuring diaphragms can be acted upon by pressure. The evaluation is done with four strain gauges applied to each measuring diaphragm, the strain gauges being interconnected to form a Wheatstone bridge. Because it is possible to mount the sensor plate in a way that optimizes strain, it is possible to measure various pressures with minimal measurement error using one sensor plate.Type: GrantFiled: December 16, 1997Date of Patent: February 2, 1999Assignee: Robert Bosch GmbHInventor: Rainer Willig

Patent number: 5767404Abstract: A measuring element (26) for detecting the movement of a vehicle to be monitored and an electrical circuit (35) for evaluating the measuring signals of the measuring sensor (26) are disposed in a housing (10) of a rotation rate sensor. The circuit (35) is connected with the measuring element (26) with the aid of a flexible printed circuit board (36). The printed circuit board (36) is bent 90 degrees in the area of the measuring element (26) in order to make possible a compact and space-saving construction in the housing (10, 11, 12). The printed circuit board (36) has a cutout (39) and two strips (40, 41) extending parallel with the cutout (39) in the bending area in order to make simple bending possible. It is furthermore possible in a simple way to insert a temperature sensor (45) into the one end (38) of the printed circuit board (36) in order to make possible a simple compensation of the deviation of the temperature.Type: GrantFiled: June 3, 1996Date of Patent: June 16, 1998Assignee: Robert Bosch GmbHInventors: Harry Kaiser, Rainer Willig
