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
