    摘要： A control apparatus for protected switching of a load encompasses at least two switch units in series with a load, to permit delivery of energy to a load when each switch unit is switched on and to block it when at least one of the switch units is shut off; an electronic control system for triggering each switch unit via a first switching path and second switching paths, and for monitoring its state; a delay element on the first switching path, such that each switch unit can be shut off both by way of a shutoff signal conveyed via the first switching path and by way of a shutoff signal conveyed via the second switching path; and in a state in which one of the switch units is shut off and the other is switched on, the electronic control system ascertains a malfunction of the first switching path if, after output of a shutoff signal on the first switching path, the other switch unit does not shut off within a predefined time window.

    摘要： A sensor is provided, in particular a gas sensor for determining the concentration of a gas component in a measuring gas, which has a sensor element that projects from a housing by a measuring-gas-side end section exposed to the measuring gas, and a sheath tube having gas passageways, which is placed over the measuring-gas-side end section and affixed on the housing. To prevent condensation of water vapor contained in the measuring gas in the measuring space enclosed by the housing and the sheath tube, and thus the production of water droplets that reach the hot sensor element, sheath tube and/or sensor element are/is thermally decoupled from the housing. The thermal decoupling is produced using, for instance, a flange sleeve made of a material having poor thermal conductivity, which separates the sheath tube from the housing by a flange and, via a sleeve section, is inserted in the space between the housing and the measuring-gas-side end section of the sensor element.

    摘要： The invention is directed to a method for detecting and documenting damage to a catalytic converter in a motor vehicle having a fuel tank and an internal combustion engine wherein combustion misfires can occur when the level of fuel in the tank drops below a critical level. The method includes: detecting the level of fuel in the tank utilizing a fill-level sensor device; utilizing a circuit arrangement to determine when the level in the tank reaches the critical level and switching on a warning lamp to indicate that the critical level has been reached; storing a value corresponding to the critical level and the operating state of the warning lamp in a memory as a first set of data; detecting misfires of the engine and storing information as to the misfires in the memory as a second set of data; and, logically combining the first and second sets of data when the misfires are present at the same time as the critical fill level so that a determination can be made in the context of a later read out of the logically coupled data as to whether the misfires are associated with a level of the fuel corresponding to the critical level.

    摘要： The invention relates to a method for diagnosing the function of an adjusting device and includes the steps of: driving the adjusting device, detecting the effect of driving the adjusting device on a predetermined variable operatively coupled to the adjusting device; determining the adjusting device to be operable when the effect lies in a first range of possible values; and, determining the adjusting device to be inoperable when the effect lies in a second range of possible values. A third range is defined which separates the first and second ranges from each other. The method is interrupted or repeated when the effect lies in the third range.
