Abstract: A system (1) for calibrating an image capture device (2) mounted on a motor vehicle for offset from an ideal position and an ideal angular orientation while the vehicle is moving comprises selecting an image (12) in a captured image frame (10) of a stationary object relative to the motor vehicle, which is capable of being tracked through a plurality of successively captured image frames (14a,14d), predicting the locations at which the target image (12b) should appear in the respective successively captured image frames (14a,14d), comparing the actual location of the target image (12a) in the respective successively captured image frames (14a,14d) with the respective predicted locations (12b) and determining calibration values for the camera (2) from the results of the comparison, in the event that the actual (12a) and predicted locations (12b) of the target image in the respective image frames (14a,14d) do not coincide.

Abstract: The invention relates to an inductively operating sensor (1) for measuring the electrical conductivity of a fluid medium (2), having an excitation coil (3) to which an input signal is fed and a receiver coil (4) coupled to the excitation coil (3) via the fluid medium (2), the receiver coil (4) providing an output signal (IInd) which is a measurement of the conductivity of the fluid medium (2). The sensor (1) has means (5) for measuring a variable signal at the input of the excitation coil (3) for timely detection of damage to the windings of the excitation coil (3), the receiver coil (4), and/or to a power cable network for the sensor (1). The excitation coil (3) of the sensor is preferably fed by an input voltage (UErr) and the means (5) for measuring the variable signal preferably measure the input current (IErr) at the input of the excitation coil (3).

Abstract: The invention relates to an inductively operating sensor (1) for measuring the electrical conductivity of a fluid medium (2), having an excitation coil (3), to which an input signal is fed, and a receiver coil (4) coupled with the former via the fluid medium (2), which provides an output signal (IInd), which is a measurement for the conductivity of the fluid medium (2). To make possible the timely detection of damage to the windings of the excitation coil (3) or the receiver coil (4), or respectively a service cable for the sensor (1), which leads to leak currents or short circuits, it is proposed by the invention that the sensor (1) has means (5) for measuring a variable signal at the input of the excitation coil (3). The excitation coil (3) of the sensor is preferably fed by an input voltage (UErr), and the means (5) for measuring the variable signal preferably measure the input current (IErr) at the input of the excitation coil (3).
