Patent number: 9371031Abstract: In a method for controlling a headlamp system for a vehicle, the headlamp system having two headlamps, set apart from each other, road users are detected in front of the vehicle in the driving direction, and a first total light pattern is able to be produced, in which the illumination range on a first side of a center axis is greater than on the other, second side of this center axis, and a second total light pattern is able to be produced, in which the total light pattern is controllable such that it has an illumination range in the direction of at least one detected road user that is less than the distance to the detected road user, and which has an illumination range in another direction that is greater than the distance to the detected road user.Type: GrantFiled: September 22, 2015Date of Patent: June 21, 2016Assignee: VOLKSWAGEN AGInventors: Karsten Dierks, Martin Freese, Bernd Jahrsau

Patent number: 9284659Abstract: A method for crystallizing a substance dissolved in a solvent, including the following steps: introducing a solvent volume containing the substance into a chamber having a preset temperature, humidity, and gas composition, adding a predetermined volume of a precipitant to the solvent volume containing the substance, allowing the solvent to evaporate while simultaneously observing structural changes in the solvent volume containing the substance and the precipitant by means of dynamic light scattering, detecting weight changes and determining the molarities, making an association with the location in the phase diagram on the basis of the DLS measurement and the results of the molarity determination, allowing a predetermined number of crystal nuclei to form by adding solvent or adding precipitant, putting the solvent volume containing the substance and the precipitant into a metastable state by adding solvent and/or protein solution or by allowing the concentration of the dissolved substance to decrease by alloType: GrantFiled: June 30, 2011Date of Patent: March 15, 2016Assignee: Xtal Concepts GmbHInventors: Christian Betzel, Rolf Hilgenfeld, Dierk Hilterhaus, Thomas Klupsch, Peter Muehlig, Karsten Dierks, Arne Meyer

Patent number: 8862336Abstract: In a method for controlling a headlamp system of a vehicle, road users are detected in front of the vehicle in the driving direction, and a total light pattern produced by the headlamp system is controlled such that it provides an illumination range in the direction of at least one detected road user that is less than the distance to the detected road user, and which provides an illumination range in another direction that is greater than the distance to the detected road user. The illumination range in the other direction is controlled as a function of the horizontal angle between the driving direction of the vehicle and the connecting line from the vehicle to the detected road user or to another detected road user.Type: GrantFiled: October 18, 2010Date of Patent: October 14, 2014Assignee: Volkswagen AGInventors: Karsten Dierks, Martin Freese, Bernd Jahrsau
