Publication number: 20150204502Abstract: An adjusting device for headlights which has adjustment means for adjusting a light distribution having a cut-off line to a predetermined position. The headlight has a matrix of semi-conductor-based light sources and an optical unit arranged in the main direction of the beam in front of the light sources for reproducing the light sources as a number of adjacent light spots which form the light distribution. First adjustment means are provided for aligning a vertical cut-off line of the light distribution in a vertical reference line on a screen arranged at a distance from the headlight. Second adjustment means are provided so that the vertical cut-off line of the light distribution can be displaced by a horizontal adjustment path, which is smaller than a horizontal width of a light spot limiting the vertical cut-off line.Type: ApplicationFiled: January 21, 2015Publication date: July 23, 2015Inventors: Michael Kleinkes, Ulrich Knaack, Christian Schmidt

Patent number: 7368217Abstract: The invention relates to a process for the production of a multi-layer image, preferably a multi-color image. A transfer film which is applied to a paper ubstrate and which is treated with laser irradiation is used. The transfer film has a laser-sensitive layer and a background layer arranged therebeneath. The laser-sensitive layer comprises laser-sensitive material, for example laser-sensitive pigments or other laser-sensitive coloring agents. The laser-sensitive material in the layer is region-wise bleached by laser irradiation. That results in a so-called laser-induced image component. As it is transparent or partly transparent, the background layer which is arranged therebeneath and which can have a printed image then becomes visible from above in that region. That therefore gives a multi-layer image which is formed by the laser-induced image component and by the background layer jointly.Type: GrantFiled: May 8, 2002Date of Patent: May 6, 2008Assignee: ORGA Systems GmbHInventors: Norbert Lutz, Gerhard Zinner, Matthias Schumacher, Ulrich Knaack, Dirk Fischer

Patent number: 7300694Abstract: Described is a multi-layer body having two laser-sensitive layers 4, 32. The multi-layer body is a body laminated from the overlay films 30, 32, the inlets 90, 90 and the further overlay films 30, 30. At its underside the upper overlay film 30 has a layer structure applied there, by the application of a hot stamping film. The layer structure comprises a lacquer layer 50, a reflection layer 5r, a laser-sensitive layer 4, a background layer 5 and an adhesive layer 6. A diffraction and/or hologram structure 5b is provided in the lacquer layer 5c, the reflection layer 5r and the laser-sensitive layer 4. The second laser-sensitive layer is formed by the carbon-doped overlay film 32. By means of laser treatment, it is possible to produce a laser-induced, preferably colored image component in the upper laser-sensitive layer 4 and a further laser-sensitive image component, preferably in the form of a gray scale image, in the subjacent carbon-doped laser-sensitive layer 32.Type: GrantFiled: May 8, 2002Date of Patent: November 27, 2007Assignees: Leonard Kurz GmbH & Co. KG, ORGA Systems GmbHInventors: Norbert Lutz, Gerhard Zinner, Matthias Schumacher, Ulrich Knaack, Dirk Fischer

Patent number: 7223512Abstract: The present invention relates to a process for increasing the level of safeguard in respect of forgery of paper documents. For that purpose, applied to the paper document is a transfer film or laminating film having a laser-sensitive layer. This multi-layer body is then treated with laser radiation. In that case, a laser-induced marking is produced in the laser-sensitive layer, for example, by laser-induced bleaching, laser-induced color change or laser-induced blackening. Respective individualization of the document can be effected by way of that laser-induced marking.Type: GrantFiled: May 8, 2002Date of Patent: May 29, 2007Assignee: ORGA Systems GmbHInventors: Norbert Lutz, Gerhard Zinner, Matthias Schumacher, Ulrich Knaack, Dirk Fischer

Patent number: 7220479Abstract: The present invention relates to a multi-layer body which is a paper document with a hot stamping film embossed thereon. The hot stamping film has a laser-sensitive layer in which a laser-induced color image is produced by laser treatment. Arranged on the document are further security identifications such as a security print, which is in the form of guilloche patterns, fluorescent threads, and a security strip. Water marks are also provided in the paper document.Type: GrantFiled: May 8, 2002Date of Patent: May 22, 2007Assignees: Leonard Kurz GmbH & Co., KG, Orga Systems GmbHInventors: Norbert Lutz, Gerhard Zinner, Matthias Schumacher, Ulrich Knaack, Dirk Fischer

Patent number: 6880945Abstract: A lamp for a vehicle includes a light-conducting element. The light-conducting element has at least one in-coupling element arranged between two adjacent light out-coupling elements. A light source is associated with a light in-coupling surface of the light in-coupling element. At least two light-diverting surfaces of the light in-coupling element are associated with respective ones of the light out-coupling elements. The light-diverting surfaces serve to divert light beams radiated from the light source into the respective light out-coupling elements. The light-diverting surfaces of the light in-coupling elements are convexed, or curved, outwardly and have a common focus position for the light source.Type: GrantFiled: September 19, 2001Date of Patent: April 19, 2005Assignee: Hella KG Huech & Co.Inventors: Ulrich Knaack, Lukas Schwenkschuster
