Abstract: The invention relates to a method for detecting a harmful cell voltage (U) of a cell region of a fuel cell stack, wherein the noise (201, 202) of a signal (200) of the cell voltage (U) is determined by means of a cell monitoring process corresponding individually to the fuel cell stack in order to detect harmful cell voltage (U), and a change, in particular a reduction, of the noise (201, 202) with respect to a characteristic noise (201, 202) of the cell voltage (U) is detected as a used signal for a harmful cell voltage (U).

Abstract: A guide vane wheel of a turbomachine, has a plurality of guide vanes, forming a blade row extending radially inward in a flow path of the turbomachine, and two borescope accesses. The guide vanes form two segments each with a plurality of guide vanes circumferentially spaced apart, with the two segments having the same, constant cascade pitch and the two segments spaced such that the respective outermost guide vane adjacent to the respective other segment has an enlarged spacing in the circumferential direction from the adjacent guide vane of the other segment equal to 1.3 to 1.7 times the cascade pitch, the sum of the increased spacings being equal to 3 times the cascade pitch. The increased distance between the respective two adjacent outermost guide vanes of the two segments creates an enlarged vane passage between these guide vanes where the borescope accesses are formed.

Abstract: A computer system includes at least one processor, a first mass memory and a second mass memory. The computer system implements a master operating system core, a first operating system core and at least one second operating system core on the processor under control of the master operating system core. The memory controller provides the master operating system core with defined areas of a mass storage medium as a first mass memory and at least one second mass memory, each independent of one another, and controls mapping of the first mass memory and of the at least one second mass memory to the defined areas of the mass storage medium. The master operating system core allows the first operating system core and the at least one second operating system core to have exclusive access to at least one of the mass memories.

Abstract: A method for operating a common-rail system of a motor vehicle that includes a common-rail-pressure sensor configuration having at least two signal paths, and that can be operated at a maximally permissible common-rail pressure and at a minimally permissible common-rail pressure. Sensor signals are read out in each case in response to a pressure measurement in a common rail of the common-rail system via the at least two signal paths, and a signal deviation value is ascertained that characterizes a deviation between the pressure values that are each determined on the basis of the sensor signals. The method includes reducing the maximally permissible common-rail pressure by a correction value to a maximally permissible emergency common-rail pressure and/or increasing the minimally permissible common-rail pressure by a correction value to a minimally permissible emergency common-rail pressure in response to the signal deviation value exceeding a predefined value.

Abstract: A method for systematically handling errors, and an assemblage for carrying out the method, are presented. The method serves for systematically handing errors for a goniometer in the context of the transfer of position data with a position transducer, the position transducer possessing markings that are sensed with at least one sensor; a profile being deposited in a memory region in connection with said markings; the position transducer generating as a function of its position, by way of the markings, position signals that carry, as data, parameters that are deposited into a further memory region beginning with an address pointer value of 0; said address pointer being incremented with each position signal; and a synchronization between the position signals and the profile being created, and the values stored in the profile being used to modify the number of pulses outputted to the goniometer.
