Abstract: A method for diagnosing the dynamics of a sensor in the fresh air or exhaust gas tract of internal combustion engines, as well as a computer program, a computer program product and a corresponding vehicle. It is provided that a corresponding sensor for measuring a pressure signal in the fresh air or exhaust gas tract of an internal combustion engine of a vehicle, which is coupled with a control and computing unit, is checked with respect to its dynamic characteristics. Measured values of differing frequency ranges are measured, these being used as the basis for a calculation of a characteristic. After the calculation, the characteristic is compared with a threshold value stored in a user-defined manner in the control and computing unit. If the calculated characteristic deviates from the threshold value, at least one triggering signal is triggered, so that an impaired sensor dynamic of the sensor is displayed.

Abstract: A method is provided for operating an internal combustion engine, which comprises at least one combustion unit, a fresh gas tract for supplying fresh gas to the combustion unit, and a fuel tank system. A fresh gas compressor as well as a differential pressure valve are integrated into the fresh gas tract. The first purge gas line opens into a first section of the fresh gas tract, which is situated downstream from the differential pressure valve as well as upstream from the fresh gas compressor, while the second purge gas line opens into a second section of the fresh gas tract situated downstream from the fresh gas compressor. The differential pressure valve is at least partially closed at least temporarily during an intake mode of the internal combustion engine with fuel vapor filter purging, and purge gas is introduced into the fresh gas tract via the first purge gas line.

Abstract: A method for adaptation of a detected camshaft position of a camshaft in an internal combustion engine with: Detection of an ACTUAL gas signal in a gas space that is associated with the camshaft and is associated with a detected camshaft position; Processing of the gas signal to produce an ACTUAL gas criterion; Modeling of multiple simulated gas criteria, each of which is associated with a target camshaft position; Determination of a simulated gas criterion with the least deviation from the ACTUAL gas criterion; Determination of an ACTUAL camshaft position that corresponds to the simulated gas criterion with the least deviation from the ACTUAL gas criterion; Determination of a camshaft position correction value from the difference between the ACTUAL camshaft position determined and the detected camshaft position; Determination of corrected camshaft positions by correcting the detected camshaft positions with the camshaft position correction value.

Abstract: A control configuration for a combustion engine includes a control unit which has a function that determines a reference variable by taking into account an operating state information, an upper limit and a cumulative actual variable. The reference variable influences an operating state of the combustion engine such that a plurality of actual variables are adjusted so that, in an operating time period with a combination of arbitrary different operating states of the combustion engine that are set in a random order, cumulative actual variables do not exceed upper limits in this operating time period, wherein a target function is minimized by selecting the reference variable from Pareto-optimal alternatives through use of an indifference curve. A combustion engine and a vehicle are also provided.

Abstract: A conductor transportation device for cables has a pivoting conductor conveyor. A first drive moves the conductor conveyor about a pivotal axis. The conductor conveyor has a conveyance (30a) such as, a conveyor belt running around a drive roller and a roller, together with a pressure application. A second drive is present for the. The axes of rotation of rollers (30b, c, e, f) for the conveyance and pressure application are parallel to one another and also to the pivotal axis of the conductor conveyor. A drive axis of the drive is coincident with one of the axes of rotation of the rollers. One of the axes of rotation of the rollers is coincident with the pivotal axis for the conductor conveyor. The actuation paths of the pivotal axis and the conveyor roller or the driven roller are spaced apart.

The controller (11) can transmit at least one control signal to at least one modulator (M1, M2, . . . , Mn) using at least one first transmission path (3). Each power semiconductor switch (S1, S2, . . . , Sn) is connected to a respective control electrode driver stage (G1, G2, . . . , Gn) and the at least one modulator (M1, M2, . . . , Mn) can transmit at least one drive signal to each of the control electrode driver stages (G1, G2, . . . , Gn) using a respective second transmission path (4). At least one control signal and/or a drive signal can be transmitted using electromagnetic radiation and the associated transmission path (3, 4) is wireless.

Abstract: A helmet sock for protecting a helmet wearer from cold weather conditions while snowmobiling, motorcycling, skiing and other like activies. The helmet sock attaches to the outside lower perimeter of a helmet by a strip of hook and loop material such as Velcro-type material. A strip of Velcro-type material is secured to the outside lower perimeter of the helmet by pressure sensitive adhesive and a corresponding strip is attached to the upper inside circumference of the sock. The sock comprises an adjustable flap at the rear of the helmet for making a secure airtight fit on the helmet. The sock prevents outside air from penetrating and retains the body heat of the wearer in addition to stopping snow and wind from entering the bottom of the helmet. When the weather temperature rises, the sock may be rolled up and stretched around the bottom of the helmet or simply pulled off the perimeter of the helmet.
