  • Publication number: 20180134606
    Abstract: A method for separating a portion from a sheet glass element having a thickness of at least 2 millimeters along an intended separation line that divides the sheet glass element into the portion and a remaining main part is provided. The method includes producing filamentary damages comprising sub-micrometer hollow channels in a volume of the glass sheet element adjacently aligned along the separation line; and heating and/or cooling the glass sheet element to cause expansion and/or contraction so that the portion detaches from the main part along the separation line. The portion and the remaining main part each remain intact as a whole. The step of producing the filamentary damages includes generating a plasma within the volume with laser pulses of an ultrashort pulse laser; and displacing points of incidence of the laser pulses over a surface of the glass sheet element along the separation line.

  • Publication number: 20180134604
    Abstract: A method is provided that includes producing filamentary damages in a volume of a glass or glass ceramic element adjacently aligned along a separation line and extend obliquely relative to a surface of the glass or glass ceramic element; and separating a portion from the glass or glass ceramic element along the separation line. The step of producing the filamentary damages includes directing laser pulses of an ultrashort pulse laser obliquely on the surface so that the laser pulses have a light propagation direction that extends obliquely relative to the surface and so that the filamentary damages resulting from the laser pulses have the longitudinal extension that extends obliquely relative to the surface; generating a plasma within the volume with the laser pulses; and displacing the laser pulses at points of incidence over the surface along the separation line.

    Abstract: A method for a high-voltage energy system of a vehicle wherein a pre-accident error state is determined which shows the current existing error of the high-voltage energy system prior to the time of an accident. Then an accident event is determined. A post-accident error state is determined which shows the current existing error of the high-voltage energy system according to the time of the accident. The high-voltage energy system is deactivated in accordance with the accident, the pre-accident error state, and the post-accident error state.

  • Publication number: 20180037490
    Abstract: A method for cutting a thin glass including the steps of guiding, by a transport device, the thin glass ribbon over a levitation support, and directing, within a range of the levitation support, a laser beam onto the thin glass ribbon, which heats up the thin glass ribbon at an impingement point of the laser beam. The method also includes the step of blowing, by a cooling jet generator, a cooling fluid onto the track heated by the laser beam so that a region heated by the laser beam is cooled down and a mechanical stress is created. The cooling fluid contains vapor of a liquid at a saturation ratio of at least 0.5 or a plurality of liquid droplets. The liquid droplets form a contact angle on a surface of the thin glass ribbon which is smaller than that of water on the same surface.
