Abstract: A device for recognizing an impairment of a lever sensor, wherein the lever sensor detects measured values with respect to a filling level of a liquid container of a motor vehicle. The device determines a maximum measured value and a minimum measured value of the lever sensor in a time and/or distance interval of a first phase. The device further determines, in a second phase following the first phase, proportion information relating to a proportion of a time and/or distance interval of the second phase, for which the measured values of the lever sensor lie within a minimum value range for the minimum measured value of the first phase and/or within a maximum value range for the maximum measured value of the first phase, and recognizes an impairment of the lever sensor on the basis of the proportion information.

Abstract: Please substitute the new Abstract submitted herewith for the original Abstract: A device for determining a value of fuel volume in a fuel container for a current point in time is configured to determine an estimated value of the fuel volume for the current point in time based on a previous value of the fuel volume for a previous point in time and based on extraction data relating to fuel extraction from the fuel container, determine a minimum value and/or a maximum value of the fuel volume for the current point in time based on a measurement value from a fill level sensor of the fuel container for the current point in time, and determine the value of the fuel volume for the current point in time based on the estimated value of the fuel volume and based on the minimum value and/or the maximum value of the fuel volume for the current point in time.

Abstract: A container for storing a fluid may have one or more of the following features: container walls which define a cavity for storing the fluid, and a positioning system via which at least one component inside the cavity can be positioned in a guided manner.

Abstract: An industrial truck is shown with a lifting frame, on which a load-receiving section is arranged so as to be movable vertically. The load-receiving section has at least one degree of movement freedom with respect to the lifting frame, which lies in a plane perpendicular to the main direction of travel of the industrial truck and has at least one horizontal component. In addition, a vibration control system is provided for damping or preventing vibrations in the relative position of load-receiving section and lifting frame.

Abstract: The present invention is directed toward a filter head that is adapted to mount a filter between an upstream fluid supply and a downstream fluid pump such as might be used for an oil burner system that includes a combination of the filter head and the safety valve in a single unit that may be interposed at a location along an oil conduit. The filter head comprises a filter head housing having an inlet port and an outlet port and a filter mounting stub that is adapted to mount the filter thereto. The filter mounting stub provides a filter head entrance port and a filter head exit port fluidically between the inlet and the outlet ports for communication with the filter when mounted thereto. A safety valve is mounted in the filter head housing and is arranged fluidically between the inlet and outlet port of the filter head housing. The safety valve has open and closed positions and opens in response to vacuum pressure at the outlet port.
