  • Patent number: 8481975
    Abstract: The invention relates to a method for optically detecting surfaces wherein strip patterns are projected onto the surface, images are captured, and the three-dimensional contour thereof is determined from the reproduction of the strip pattern on the surface of the object. The aim of the invention is to prevent reflections that interfere with the images and as a result, the surface of the object is covered with a layer of a fluorescent material, is then radiated with ultraviolet radiation, and the radiation emitted by the fluorescent material in the visible light is detected.

  • Patent number: 8443766
    Abstract: A method for automatically controlling an internal combustion engine, where, during normal operation in a first controller mode, a charge air temperature controller is set as dominant for a map-controlled thermostatic valve for automatically controlling the charge air temperature (TLL), or, during normal operation in a second controller mode, a coolant temperature limit controller is set as dominant for the map-controlled thermostatic valve for automatically controlling the coolant temperature (TKM). If a charge air temperature sensor fails, the second controller mode is set with the coolant temperature limit controller dominant, and if a coolant temperature sensor fails, the first controller mode is set with the charge air temperature controller dominant.

    Abstract: A pre-chamber sparkplug is suggested with a central electrode, with at least one ground electrode, which is distanced from the central electrode forming a spark gap, and with at least one transfer bore in a pre-chamber cap. The ground electrode comprises an internal circumferential area, which faces the central electrode, and an external circumferential area, which faces away from the central electrode. The internal circumferential area of the ground electrode shows a concave progression in the longitudinal direction of the pre-chamber sparkplug, subjected to a tensile force, and the external circumferential area shows a convex progression in the longitudinal direction of the pre-chamber sparkplug, subjected to a pressure.
