Abstract: A roller cutter arrangement for a cutting wheel of a tunnel boring machine, including an interchangeable cup, a bearing block which is supported in the interchangeable cup in such a way that it is displaceable along a displacement axis, and a cutting roller unit having at least one cutting roller, which is rotatably supported in the bearing block and which acts along a working axis. The working axis is angled with respect to the displacement axis, so that cutting rollers of the cutting roller units may be situated in close proximity to one another, in particular in the central area of the cutting wheel.

Abstract: A method for controlling an electric machine or electric unit by actuating a component of the electric machine or unit using a predicate and by automatically examining the component in regard to the performance of the predicate to permit examination of an automated system for possible errors in a simply manner, wherein the predicate contains an expected value of a (physical) quantity of the component, and wherein in the examination of the component, a check is performed to determine whether the expected value actually arises when the predicate is performed such that erroneous situations can be detected by a runtime system without explicit programming being necessary therefor.

Abstract: A method for operating a motor vehicle having an internal combustion engine. In the method, the operation of the motor vehicle is influenced as a function of at least one operating parameter determined during an operating time of the motor vehicle. In order to take wear and tear of the motor vehicle and the internal combustion engine into consideration, an operating parameter suitable for determining wear and tear of the motor vehicle is detected, a value corresponding to the wear and tear is determined, and the operation of the motor vehicle is adjusted according to the determined value.

Abstract: A method for error detection and error correction in the monitoring of measurement values is disclosed, in which the value to be tested is checked for plausibility in an evaluation device, for example a computer, and in the event that an implausibility is identified, the existence of an error is determined. If a further check finds that the error no longer exists, then an error correction takes place. A prerequisite for the error correction, however, is that the range of the value to be monitored in which the error has occurred is also the range in which a current error is no longer occurring. In an expanded method, a differentiation is also made between different errors and an error correction is only possible if it involves the same type of error.

Abstract: A fuel injecting method and a corresponding arrangement for an internal combustion (10), especially of a motor vehicle, wherein a first injection takes place during an induction stroke. Proceeding from operating characteristic variables of the engine (10), a tendency-to-knock signal is determined which characterizes the tendency to knock of the engine (10). At least one second injection takes place when the tendency-to-knock signal exceeds a threshold value. (FIG.

Abstract: A method for controlling ignition in a multi-cylinder internal combustion engine, such that the control variables are determined on the basis of the parameters sensed by sensors, and such that after output of the control variables, a misfire monitoring operation is performed. After output of an ignition signal, the torque of the combustion event initiated by the ignition event is sensed and compared with an average of the torques of previous combustion events. If, in this context, a deviation of the currently sensed torque from the average of the torques of a definable number of previous combustion events which is greater than a definable threshold occurs, the misfire detection system is switched to inactive status.

Abstract: An on-board diagnostic arrangement is disclosed for checking component systems of a motor vehicle by test functions which are triggered during operation of the motor vehicle under predetermined start conditions. The test functions are characterized in that at least one signal can be coupled into the arrangement via which the triggering of the test functions by the arrangement is inhibited and in that at least one test function, which is carried out by the arrangement, is triggered independently of the predetermined start conditions and/or can be modified in its sequence. The arrangement makes possible a shortening of the check of component systems at the end of an assembly line or after customer service because satisfying time-consuming start conditions for the normal operation of the test functions can be omitted.

Abstract: A structural element for thermal insulation between two structural elements to be covered with concrete, especially a building and a projecting external part, has an insulating body to be inserted in between the structual elements and has at least integral compression elements which run transverse to the longitudinal extension of the insulating body and through them and are respectively connected to both structural elements, wherein the compression elements can have of a profile body with several especially vertically running compression bars, and wherein the length of the compression elements in the direction of the longitudinal extension of the insulating body amounts to a multiple of their vertical height.

Abstract: A method for detecting knocking provides for weighting or limitation of the knocking threshold. For this purpose, on the one hand a normal range of the reference level is defined and in the case of a deviation from this normal range the knocking threshold is multiplied by a weighting factor less than 1 and, alternatively, the knocking threshold is limited when a prescribable limit value is reached.
