    摘要： An integrated adjustable capacitor device and method for making such a device are provided. The adjustable capacitor includes an underlying electrode, a dielectric cavity, an upper electrode, and an etch cavity for removing sacrificial material from the dielectric cavity. The surface of the device is relatively flat due to epitaxal deposition of epi polysilicon and single crystal silicon. The adjustable capacitor system is capable of undergoing CMOS processes without requiring additional steps of covering the capacitor device to protect it and then removing the covering following the CMOS processes.

    摘要： A gyroscope system including multiple rotating or oscillating disks filters out disturbance acceleration inputs such as vibrations or jarring while detecting and measuring external angular velocity. The gyroscope disks are decoupled from a substrate to decrease the impact of external vibrations on the gyroscope operation. The gyroscope disks are rotated in opposite directions or oscillated out of phase to decrease the impact of disturbance vibrations and jarring while more accurately measuring external angular velocities applied to the system.

    摘要： 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. The centers of gravity of the first Coriolis mass element, the second Coriolis mass element, the first detection mass device and the second detection mass device may coincide at a common mass center of gravity when they are at rest.

    摘要： In the method and device for tuning a first oscillator with a second oscillator respective response signals of the first oscillator are produced from corresponding frequency-shifted and/or phase-shifted signals of the second oscillator. The first oscillator is tuned to the second oscillator according to the difference of the respective response signals. For amplitude correction a quotient is formed by dividing an output signal by the sum of the response signals. The method and device according to the invention are especially useful in a rotation rate sensor. The invention also includes a rotation rate sensor, which includes a device for determining rotation rate from the oscillations of a first and second oscillator and the device for tuning the first oscillator with the second oscillator.
