A method for ascertaining output data of a global navigation satellite system (GNSS) locating device based on GNSS satellite signals in a vehicle, includes a) receiving surroundings data from the surroundings of the vehicle, b) generating a surroundings model to describe the surroundings of the vehicle using the surroundings data received in step a), c) receiving GNSS satellite signals from GNSS satellites using a GNSS receiver, and d) ascertaining output data of the GNSS locating device from the GNSS satellite signals received in step a). The surroundings model generated in step b) is used to compensate for anomalies caused by the surroundings of the propagation of the GNSS satellite signals from the GNSS satellites to the GNSS receiver.

A rotational acceleration sensor having a substrate, a mass movable with respect to the substrate, a suspension means suspending the mass movably relative to the substrate, a detection means for detecting a state of the mass deflected with respect to an idle position, and a detection means encompassing a first detection unit for detecting a deflected state of the mass i.e., a pivoting of the mass around a first axis substantially perpendicular to a principal extension plane of the substrate as a result of a rotational acceleration of the rotational acceleration sensor around the first axis. The detection means also encompassing a second detection unit for detecting a deflected state of the mass, i.e., a pivoting of the mass around a second axis substantially parallel to the principal extension plane of the substrate as a result of a rotational acceleration of the rotational acceleration sensor around the second axis.

The disclosure relates to an arrangement for detecting connection loss at a circuit part which has a capacitive behavior and is electrically connected to a useful signal source. The disclosure provides an evaluation circuit which is electrically connected to an input node of the circuit part having a capacitive behavior and detects the pulsed useful signal (UNUTZ), output by the useful signal source, at the input node of the circuit part having a capacitive behavior and evaluates the signal characteristics in order to detect connection loss.

A yaw rate sensor () includes a movable mass structure () and a drive component () which is suitable for setting the movable mass structure () in motion (), and an analysis component () which is suitable for detecting a response () of the movable mass structure () to a yaw rate (&#x3a9;). A method for functional testing of a yaw rate sensor () includes the following steps: driving a movable mass structure (), feeding a test signal () into a quadrature control loop () at a feed point () of the quadrature control loop (), feeding back a deflection () of the movable mass structure (), detecting a measure of the feedback of the movable mass structure (), and reading out the response signal () from the quadrature control loop (). In the yaw rate sensor () and also in the method, the readout of the response signal () in relation to a processing direction () of the test signal () is provided between a feed point () for a test signal () and an actuator () for feeding back a deflection () of the movable mass structure ().

A circuit assembly for plausibility checking of sensor signals, which can be generated by at least two separate sensor elements, includes at least one evaluation and control unit which receives the sensor signals via at least one interface unit and evaluates the received sensor signals for generating sensor data. A first evaluation and control unit is configured to receive the sensor signals of a first sensor element and to generate first sensor data from the first sensor signals. The first evaluation and control unit is configured to provide the generated first sensor data via at least one interface unit to a second evaluation and control unit, which receives and evaluates the sensor signals of a second sensor element to generate second sensor data. The second evaluation and control unit compares the generated second sensor data and the generated first sensor data to each other and inspects them for plausibility.

A device for controlling a device by using a rotation-rate sensor. In order to provide a device for determining a triggering signal for a safety device which allows a particularly compact implementation of the device, the device is set up to ascertain an acceleration variable on the basis of a first sensor signal for a first seismic mass of the rotation-rate sensor and the second sensor signal for a second seismic mass of the rotation-rate sensor and to control the device as a function of the acceleration variable.

A component is provided for an impedance change in a coplanar waveguide which includes two grounding conductors and a signal line lying between the grounding conductors, as well as a conducting connecting element, which has a covering surface for the two grounding conductors and the signal line, and is electrically insulated, so that in each case a capacitor is formed. The connecting element and the lines are situated and arranged so that the respective capacitor between the grounding conductors and the connecting element has an invariable capacitance, but the capacitor between the connecting element and the signal line has a variable capacitance. A structure is also provided in which in an exactly opposite way, the respective capacitor between the grounding conductors and the connecting element has a variable capacitance, but the capacitor between the connecting element and the signal line has an invariable capacitance. Furthermore, a method for producing such a component is also provided.
