A sensor structure includes a substrate having a main extension plane, a first seismic mass and a second seismic mass, the first and the second seismic masses being deflectable relative to the substrate along a direction of deflection essentially perpendicular to the main extension plane. The first and second seismic masses are coupled together via a rigid coupling rocker pivotable around a rocker axis parallel to the main extension plane. The first seismic mass is suspended from the substrate with the aid of a first suspension spring, and an essentially rigid first coupling bar is situated between the first suspension spring and the first seismic mass.

Sensor structure and yaw rate sensor

A method for operating and/or measuring a micromechanical device. The device has a first and second seismic mass which are movable by oscillation relative to a substrate; a first drive device for deflecting the first seismic mass and a second drive device for deflecting the second seismic mass, parallel to a drive direction in a first orientation; a third drive device for deflecting the first seismic mass, and a fourth drive device for deflecting the second seismic mass in parallel to the drive direction and according to a second orientation opposite from the first orientation; a first detection device for detecting drive motion of the first seismic mass; and a second detection device for detecting drive motion of the second seismic mass. A first and a second detection signal are generated by the first and second detection devices, the first detection signal being evaluated separately from the second detection signal.

Method for operating and/or for measuring a micromechanical device, and micromechanical device

A micromechanical component including a mass structure which may be deflected with respect to a substrate with the aid of at least one spiral spring in a direction of deflection. The spiral spring includes at least one folding section, which is formed by two spring legs which are situated essentially in parallel to each other and are connected to each other with the aid of a connecting bar. A damping device for oscillating movements of the folding section in the direction of deflection is provided in the area of the connecting bar.

Micromechanical component having a damping device

A micromechanical structure including a substrate having a main plane of extension, and including a first seismic mass, the first seismic mass including a grid structure made of intersecting first mass lines and the first seismic mass being flexibly secured with the aid of first bending-spring elements, and moreover, a first line width of the first mass lines parallel to the main plane of extension being between 20 and 50 percent of a further first line width of the first bending-spring elements parallel to the main plane of extension.

Micromechanical structures

A rotation-rate sensor includes a substrate having a surface, a movable element situated above the surface, which is deflectable based on a Coriolis force along a first axis that runs perpendicular to the surface, a driving device which is prepared to activate the movable element along a second axis that runs parallel to the surface, a compensation device, in order to generate an electrostatic force along the first axis, including electrodes corresponding to one another, developed on the substrate and on the movable element; a relative degree of covering of the electrodes in the direction of the first axis being a function of the deflection of the movable element along the second axis; and the electrode developed on the movable element runs around an insulating region of the movable element.

Quadrature compensation for a rotation-rate sensor

A method for compensating for the quadrature of a micromechanical structure, the micromechanical structure having a substrate having a main extension plane, a seismic mass that is attached by spring elements to the substrate, and first and second compensation electrodes anchored to the substrate; in response to application of a first quadrature voltage between the first compensation electrode and the seismic mass, a first compensation force being produced on the seismic mass and, in response to application of a second quadrature voltage between the second compensation electrode and the seismic mass, a second compensation force being produced on the seismic mass and, in addition, the second quadrature voltage being adjusted as a function of the first quadrature voltage.

Method for compensating for quadrature

A parking aid for a vehicle used for detecting parking spaces as the vehicle travels past the parking spaces. Properties of the parking spaces are stored in a memory and information on the parking spaces is output in an output unit.
