Abstract: An object collision warning system for a motor vehicle comprises a sensing means (11) adapted to sense a surrounding of the motor vehicle and a processing means (14) adapted to detect objects in a surrounding of the motor vehicle by processing a signal provided by the sensing means (11), to perform an estimation of a collision probability between the vehicle and the detected object, and to output a corresponding signal in case the collision probability is non-negligible. The processing means (14) is adapted to determine, after having passed a curve, information describing the passed curve, to store the curve describing information, and to use the curve describing information of at least one previously passed curve for determining the vehicle path in a current curve in the estimation of the collision probability.

Abstract: A device estimates time errors in a time interleaved A/D converter system. To this end an output signal (y1, y2, . . . , yM) is fed to a correction device (5), that is provided to correct the signals with an estimated time error and to produce M signals (z1, z2, . . . , zM). These signals are used in an estimation algorithm device to estimate the time error and the time estimated time errors are then fed to the correction device (5).

Abstract: A parallel analog-to-digital converter device has parallel converter cells signal (u) appearing at an input line. The cells are clocked by a common clock signal delayed by delay elements for the respective cell. Timing errors of the sampling times are determined in a calculation unit receiving the output signals of the cells. The output signal of the total converter is compensated by a compensation device for the determined timing errors to provide corrected sampled values on the output line of the converter. In the calculation unit sums of squared differences of the sampled values for successive cells are calculated which by simple operations provide estimates of the timing errors. In the calculation unit also a variance of noise superposed on the sampled values can be estimated and then used to correct the calculated sums for the variance. The input signal is basically unknown and the determination of the timing errors works without using any calibration signal.
