Abstract: An operating assistance method for a working device or for a vehicle. Object boxes for an object in a field of view of the working device are obtained at consecutive times. From object boxes of a given object, for images recorded in succession or direct succession, an instantaneous change of scale of an object box for the specific object, and an instantaneous lateral change of position of the object box for the specific object, are determined. An object box predicted in the future is determined from the current change of scale, and from the instantaneous lateral change in position for an object box for a specific object. The position of the predicted object box and/or the ratio of a lateral extension of the predicted object box to a lateral extension of a covered field of view and/or of the recorded images are determined and evaluated.

Abstract: A method and a device for fusion welding one or more steel sheets made of press-hardenable steel, preferably manganese-boron steel; are disclosed. In the method, the fusion welding is performed by supplying filler wire into a molten bath generated a laser beam. In order to improve the hardenability of the weld seam, regardless of whether the steel sheets to be welded to one another are steel sheets of identical or different material quality, the filler wire is coated with graphite particles prior to fusion welding and the filler wire coated in this manner is introduced directly into the molten bath in such a way that the tip of the filler wire melts in the molten bath, the graphite particles are mixed with a waxy or liquid carrier medium to be applied to the filler wire, and the mixture is applied in the form of a coating to the filler wire. The method and the corresponding device are distinguished by a high productivity and a relatively low energy consumption.
