Abstract: A method and arrangement are configured for determination of the energy consumption of a transportation device per section of the route, in urban traffic, for example. In an embodiment, current energy consumption data is compared to reference data from a fleet of transportation devices. The result is visually conveyed to the driver to allow them an interpretation of the energy consumption and to provide motivation for energy-saving driving behavior. An evaluation of the energy consumption data relative to the route allows specific feedback, for example, that the driver has achieved an energy-saving best value for a section of the route. The gathered data can also be used to pay bonuses or to initiate training measures.

Abstract: A method and an arrangement are provided to determine the speed of the wind, which acts on a wind-blade of a wind-turbine. An optical-signal with a known frequency is sent from an optical-transmit-unit to a joint measurement volume. The optical-signal is scattered and reflected by atmospheric particles of the joint measurement volume. The optical signal is shifted in its frequency due to the Doppler-principle, too. The frequency-shifted optical signal is received by a receive-unit. The frequency-shifted optical signal is compared with the sent optical-signal to determine the wind-speed based on the shifted frequency, which is caused by the atmospheric particles.

A polyphase power converter with distributed energy stores (9) is therefore operated with redundancy.

Abstract: A method is disclosed for noise reduction in images with locally different and directional noise, in particular for noise reduction in image data records of computed tomography. In at least one embodiment of the method, two image data records of an identical object region that have mutually independent noise are provided. The two image data records are decomposed by a discrete wavelet transformation into a number of frequency bands, detailed images having high frequency structures being obtained in at least two different directions. Noise images in the respective frequency bands and directions are obtained by subtracting a wavelet coefficient of the two input images. These noise images are used to estimate noise locally and as a function of direction, and on the basis of this estimate local threshold values are calculated and applied to the averaged wavelet coefficients of the input images. A result image with reduced noise is obtained after an inverse wavelet transformation.

The method and system are capable of automatic alignment of leg-volumes in whole-body MR scans that is insensitive to leg movement. In order to align upper and lower MR volumes, an automatic determination may be made that a junction between the upper and lower MR volumes is in a leg region. The lower MR volume is then divided into left and right regions, and each of the left and right regions are independently aligned with the upper MR volume. One of the left and right regions is then adjusted with respect to the other one to compensate for shifting of the legs with respect to each other.

Abstract: A sensor has a detection device and an evaluation device to detect an analog signal, to determine a digital signal and to transmit the digital signal to a control device outside the sensor. The analog signal and/or the digital signal is supplied to a monitoring device of the sensor. An enable signal is transmitted to the control device only if the device being monitored is operating correctly. In a normal mode, the control device processes the digital signal further. Otherwise, it deems the transmitted digital signal to be defective and outputs a message using a malfunction of the sensor. On account of the transmission of the test signal, the sensor assumes a test mode in which it manipulates the signals which are supplied to the monitoring device in such that the monitoring device detects that the device being monitored is not operating correctly. In the test mode, the control device outputs a message using a malfunction of the sensor if the enable signal is transmitted to it in addition to each.
