  • Patent number: 11911715
    Abstract: The present invention relates to a method for the break-up of at least one emulsion and separation of the light and heavy phase with at least an de-emulsification rate of more than 95% in only one apparatus (module) within less than 5 min by applying at least one time dependent or temporal changeable electrical field wherein the at least one electrical field is a high frequency (HF) singular alternating current (AC) field with an electrical field strength between 2,000 and 100,000 V/m and a frequency (HF) between 12,000 Hz and 200,000 Hz. The present invention relates furthermore to a method for the treatment of at least one emulsion by applying at least one direct current (DC) field and at least one high frequency alternating current-HF/AC field wherein the at least one DC field, in particular a pulsed DC-field, and the at least one HF/AC field are applied in series to the emulsion to be treated. The present invention refers further to a device for conducting said methods.

  • Publication number: 20220048536
    Abstract: The invention relates to a method and to a device for testing a driver assistance system for a vehicle in a test environment. Traffic scenario descriptions are determined, which each characterize a certain traffic scenario and comprise at least one parameter, by means of which the traffic scenario in question can be adapted to constraints. The traffic scenario descriptions are stored in a traffic scenario file, in which the at least one parameter is stored in a predefined format. At least one traffic scenario description is selected on the basis of an input of a user and/or specified criteria. Furthermore, a test case is produced on the basis of the at least one selected traffic scenario description and at least one specified value for the at least one parameter.

  • Publication number: 20190032161
    Abstract: The invention provides a reliably manufacturable flat steel product based on a Fe3Al alloy and a method that allows the production of such flat steel products. For this purpose, the flat steel product is made of a steel which comprises (in % by weight) Al: 12-20%, Ti: 0.2-2%, B: 0.1-0.6%, in each case at least one element from the group “Cr, C, Mn, Si, Nb, Ta, W, Zr, V, Mo, Ni, Cu, Ca, rare earth metals, and Co” unavoidable impurities. The method according to the invention specifies that a molten steel with the stated composition is cast as a precursor in the form of a slab, thin slab or a cast strip, the precursor is then hot rolled into a hot strip.
