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: 7134337Abstract: An exemplary embodiment of the present invention creates a micromechanical rotational rate sensor having a first Coriolis mass element and a second Coriolis mass element which may be situated over a surface of a substrate. An exemplary embodiment of a micromechanical rotational rate sensor may have an activating device by which the first Coriolis mass element and the second Coriolis mass element are able to have vibrations activated along a first axis. An exemplary embodiment of a micromechanical rotational rate sensor may have a detection device by which deflections of the first Coriolis mass elements and of the second Coriolis element are able to be detected along a second axis, which is perpendicular to the first axis, on the basis of a correspondingly acting Coriolis force. The first axis and second axis may run parallel to the surface of the substrate. The detecting device may have a first detection mass device and a second detection mass device.Type: GrantFiled: January 9, 2006Date of Patent: November 14, 2006Assignee: 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: 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.
