A hollow-bodied component, which includes at least two die-cast shell elements, is suitable in particular for use as a steering component in motor vehicle running-gear assemblies. In some cases, occluding objects are identified by processing the image dataset to determine the relative positions of visual objects. Such electrical glow discharges and coronas are the result of friction electricity found at the surface of blades and vanes, and are also due to the high pressure, temperature and velocity conditions within the turbine.
