Abstract: The invention relates to a hydraulic transmission valve with a magnetizable housing which is integrally configured in one piece with a pole core cone. The transmission valve according to the invention facilitates comfortably coupling in particular startup clutches, shifting clutches or synchronization clutches in a friction locking manner. Still using a transmission valve of this type is facilitated for fewer to no transmission oil changes. Furthermore a transmission valve of this type can also be used in countries with inferior transmission oil quality. The housing includes a connection. The connection defines an anchor stroke and a concentric arrangement between the pole core cone and a pole tube. Thus, the pole tube is fixated the magnetizable pole flange. An anchor that is exclusively supported in the pole tube is magnetically separated from the pole tube through a separation layer with a thickness of 0.01 mm to 0.06 mm.

Abstract: In a graphical user interface a display is animated by activation with an input device with a first concentric menu comprising a first grouping of menu items having a subset of one or more items from a set of menu items. Then, after selecting one menu item out of the first grouping of menu items, the display is animated with at least one additional grouping of menu items that are each concentrically in a pie sliced shape. The graphical user interface can be activated by a user at any position on the display area via the input device.

Abstract: The optical DPSK demodulator converts phase into amplitude variations by delaying one path of an interferometer by one bit period. This operation includes a differentiation of the transmitted signal, which must be counteracted by applying a precoder at the TX side. By variation of the delay within the interferometer the differentiation will be changed. A reduction of the delay results in an emphasis of higher frequencies. This can be used to counteract the low pass behaviour (after detection) produced by narrowband optical filters. A penalty reduction from >2 dB to ˜1 dB is expected.

Abstract: The pipeline analog-to-digital converter has a number of subsequent comparator stages (2) where the thresholds of the comparator stages are adjusted in accordance with the digital conversion results from previous stages (18, 28, 38) so as to implement a non-linear conversion scale. In particular, the pipeline analog-to-digital converter consists of a number of comparator stages (2), which operate in accordance with a common clock signal. The comparator stages are connected in series in such a way that a residue signal from a previous stage is used as input signal of a subsequent stage for comparison during the next clock period of the clock signal. At least some of said comparator stages have, according to the invention, a threshold generator (25, 35, 45) for adjusting the threshold value of the respective comparator (22, 32, 42) in accordance with comparison results of previous comparator stages (18, 28, 38).
