An apparatus for detecting a rollover event, which includes at least one acceleration sensor in the vertical direction of the vehicle and one acceleration sensor in the horizontal direction of the vehicle. A processor of the apparatus according to the invention will start a rollover algorithm in response to an inertial event, in order, as a function of the signal of the acceleration sensor in the vertical direction to detect the rollover event and as a function of it to trip restraint devices.

In method and a control device for triggering person protection device, a signal of a planarly measuring environment sensor system and a second signal of a contact sensor system are evaluated separately in order to produce a respective trigger signal. These two trigger signals are then gated in order to produce a third trigger signal. A trigger circuit triggers the person protection device as a function of this third trigger signal.

A device for stabilizing a vehicle after a collision, including a control device having a regulation algorithm, a sensor system for recording various quantities that describe the vehicle state, and an actuator for carrying out a stabilization intervention. The driving state of the vehicle is monitored for the occurrence of a collision, a setpoint value is calculated for a vehicle movement quantity, the setpoint value being at least partly independent of the steering instruction of the driver, and the vehicle movement quantity of the vehicle is regulated to this setpoint value in the case of a collision.

A method for plausibilizing sensor signals of a vehicle system, the sensor signals being monitored with regard to compliance with one plausibility criterion or a plurality of plausibility criteria with the aid of a plausibilization algorithm. The function of the vehicle system is able to be maintained even in critical driving situations, in particular following a collision, if the driving status of the vehicle is monitored with regard to a collision and the plausibilization algorithm is modified if a collision was detected.

A method for activating additional functions in response to a rollover procedure of a vehicle, using at least one sensor and one control unit, the sensor supplying at least one unidirectional acceleration signal, having the following method steps: analyzing at least one acceleration signal in its characteristics as a function of time; processing analyzed values of the at least one acceleration signal; establishing the plausibility of the processed values using a second signal value; and activating at least one additional function in response to a rollover procedure of the vehicle in the light of the values whose plausibility has been established; as well as a control device using this method.

A deployment decision for a vehicle restraint system is reached as a function of vehicle dynamics data, at least one vehicle transverse acceleration and one yaw rate about the longitudinal axis of the vehicle being linked to one another as the vehicle dynamics data to reach the deployment decision. The vehicle transverse acceleration is then additionally subjected to a threshold value decision for reaching the deployment decision, the threshold value being set as a function of the integrated vehicle transverse acceleration and the integrated yaw rate.

An apparatus for detecting a vehicle rollover includes a sensor suite for sensing vehicle dynamics data, the sensor suite being connected to a processor which is configured in such a way that the processor detects a vehicle rollover as a function of the vehicle dynamics data and the rollover sensor suite. The processor has means for dividing an operating state of the vehicle into chronologically successive phases. In particular, the processor has means for determining, for each phase, a float angle and a transverse vehicle velocity from the vehicle dynamics data; the float angle and the transverse vehicle velocity being used, together with the data from the rollover sensor suite, for detection of the vehicle rollover.

Identification of a fingermark is performed by obtaining for a fingermark a fingermark image, storing reference fingermarks in a databank, comparing the obtained fingermark image with the reference fingermarks for identification, before the identification determining for each reference fingermark in comparison with the obtained fingermark image a similarity degree, sorting the reference fingermarks in the databank in accordance with the similarity degree, and performing the identification of the fingermark beginning with the reference fingermark which leads to the greatest similarity degree.

Method of and device for identification of fingermarks

A method for determining reference points in a fingerprint image is used for determining similarity values using a determination of orientation patterns and a comparison with reference orientation patterns, in which the similarity values are compared with a first threshold value to determine whether a reference point is identified or not. Whorl, delta or core points are identified as core points. Both a linear and a nonlinear reference orientation pattern are used for core points. The orientation pattern for an image area is converted into a vector field for comparison with the reference orientation patterns. A scattering is computed from the spectral power density, which is determined for computation of orientation patterns, and severely distorted image areas are thereby eliminated from the determination of reference points.

A device (,) for operating a windshield wiper (,) is proposed, with a moisture sensor (,) for detecting the wetness of a window that in addition to detecting rain and droplets also detects fog and drizzle. The measured values (Us) of the moisture sensor (,) are allocated incremental values (Ink) by the control unit (,). The difference between two successive incremental values (Ink) is to be added, with a sign (&plus; or &minus;), in the memory (,) to a sum (&Sgr;) of differences formed previously in the same way, and when a threshold (S) is reached by the sum (&Sgr;) stored in the memory (,), the control unit (,) trips a wiper operating mode.
