Abstract: An example control unit may include: a processor; an output device; a valve element; an actuator; and a sensor for the position of the valve element. The valve cycles and the processor records a first signal to measure a position of the valve element. The valve cycles and the processor records a second signal to measure a position of the valve element. The processor calculates a degree of wear based on the first value and the second value and the second number of valve cycles. The processor compares the degree of wear to a predefined threshold value and generates an output signal if the degree of wear exceeds the predefined threshold value.

Abstract: In a method to determine an inversion time value for contrast improvement between different tissue in a contrast agent-supported magnetic resonance imaging, a series of magnetic resonance images of an imaging area is acquired using an inversion recovery sequence with different inversion times. A structure in the magnetic resonance images is segmented and a time response of the signal intensity of image elements corresponding to one another in the magnetic resonance images of the segmented structure is automatically determined. Minima of the signal intensity in the segmented structure are determined automatically and associated with the associated inversion time values. The optimal inversion time value for contrast improvement is automatically determined from the inversion time values that have been associated with the minima of the signal intensity in the segmented structure.

Abstract: In a night vision goggle compatible color liquid crystal display, liquid crystal cells (10, 11, and 12) are arranged in a matrix in which three adjacent liquid crystal cells are respectively provided with a red, green, and blue filter. The liquid crystal cells are driven by drive circuit (17). The drive circuit (17) is controlled by a control device (15) with red, green, and blue pixel information. The brightness of a backlight source of the color display can be switched from a high value in a daytime operation to a low value for a nighttime operation. To optimize the night vision goggle compatible color liquid crystal display, the control device (15) switches off the driver of the liquid crystal cells with the red filters during the nighttime operation.

Abstract: An improved surveillance of subscribers of a mobile radio network by a monitoring center is made possible by a method for monitoring a subscriber of a mobile radio network.

Abstract: The invention relates to a method for generating an error signal which characterizes a fault current in an electrical conductor provided with two conductor ends and having charge measuring devices which are connected to each other by data lines. At least one device is attached to each end of the conductor. In the invention, charge measuring values are determined using charge measuring devices. The measured charge values take into account the direction of the charge flow and a total measured charge value is formed by addition. The error signal is generated when the total measured charge value exceeds a certain threshold value. In order to be able to detect errors in a more sensitive manner than had previously been possible, the threshold value is formed by taking into account the individual measuring tolerance of the individual charge measuring devices.
