Patent number: 11937622Abstract: The present invention relates primarily to a method for obtaining a volatile fraction from a juice and/or an alcohol-containing beverage, comprising or consisting of the following steps: (a) distilling a mixture of substances from the juice and/or the alcohol-containing beverage, wherein the distillation is performed by a spinning cone column; (b) contacting the mixture of substances from step (a) with a sorbent to obtain a loaded sorbent; and (c) contacting the loaded sorbent from step (b) with a liquid desorbent to obtain the volatile fraction, wherein desired ingredients of the volatile fraction are concentrated as compared to the juice and/or alcohol-containing beverage such that an addition of 0.1% by mass or less of the volatile fraction to any food preparation produces a perceptible odor impression and/or taste impression in a test subject.Type: GrantFiled: August 17, 2018Date of Patent: March 26, 2024Assignee: SYMRISE AGInventors: Johannes Kiefl, Dominik Winkler, Stefan Brennecke, Jens Michael Hilmer, Alexander Kindel

Publication number: 20230282028Abstract: In a computer-implemented method of augmenting a dataset used in facial expression analysis, a first facial image and a second facial image are added to a training/testing dataset and mapped to two respective points in a continuous dimensional emotion space. The position of a third point in the continuous dimensional emotion space between the first two points is determined. Augmentation is achieved when a labelled facial image is derived from the third point based on its position relative to the first and second facial expression.Type: ApplicationFiled: March 4, 2022Publication date: September 7, 2023Inventor: Stefan Winkler

Patent number: 8456531Abstract: Video alignment and calibration, which is needed for video quality measurement in full-reference mode, is performed continuously on the videos being measured to account for alignment parameters that may change over time. With this technique, the quality of video files and/or live video streams can be measured in full-reference mode in real-time. During video alignment, the temporal and spatial offsets, as well as any spatial, luminance or color transformations between the two videos are measured; during video calibration, the video frames are adjusted for these offsets and transformations so that the video quality can be measured correctly.Type: GrantFiled: January 14, 2010Date of Patent: June 4, 2013Assignee: Cheetah Technologies, L.P.Inventor: Stefan Winkler

Publication number: 20100110199Abstract: The quality of video that is broadcast as a packet-based video stream is measured using decoded pictures in combination with information extracted from the transport stream and elementary stream layers of the packet-based video stream. The decoded pictures include selected frames and/or slices decoded from the packet-based video stream and are used to generate video content metrics. A composite score for the video quality can be generated from the video content metrics in combination with quality metrics of the transport stream and/or the elementary stream. If the composite score falls below a minimum score, a snapshot of the video is captured for later analysis.Type: ApplicationFiled: November 3, 2008Publication date: May 6, 2010Inventors: Stefan Winkler, Praveen Mohandas, Yves Cognet

Patent number: 7275484Abstract: A data carrier printed by line intaglio having a halftone image represented by irregular line structures in the manner of an engraving. The line structures are superimposed at least partly by fine structures rendered in positive or negative representation. Methods are provided for generating and processing irregular line structures as digital image data on a computer following individual specifications by an operator. The line structures are transferred to a line intaglio printing plate. The digital image data is used for controlling an engraving apparatus. In the alternative, other printing processes may be involved wherein the digital image data is superimposed at least partly with fine structures rendered in positive or negative representation.Type: GrantFiled: February 25, 2005Date of Patent: October 2, 2007Assignee: Giesecke & Devrient GmbHInventors: Peter Franz, Rüdiger Schmidt, Stefan Winkler

Patent number: 7094002Abstract: Holding apparatus for supporting a dam unit, wherein the apparatus includes a frame structure including at least one support member. The at least one support member is arranged to support the dam unit when the dam unit is raised from a lowered position to a holding position. The at least one support member is at least one of detachably connected to the dam unit and removably engagable with the dam unit. The at least one support member essentially experiences compression forces when the dam unit is supported in a holding position. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.Type: GrantFiled: April 23, 2003Date of Patent: August 22, 2006Assignee: VA Tech Hydro GmbH & Co.Inventor: Stefan Winkler

Patent number: 6675631Abstract: A method of conducting crash tests uses a crash-test carriage. The crash-test carriage is accelerated in accordance with a real deceleration curve to thereby simulate deceleration forces associated with a real collision, the crash-test carriage having a carriage drive apparatus associated therewith. The method includes the step of exerting an accelerating force on the crash-test carriage in an acceleration direction, the accelerating force exceeding a respective force required for acceleration in accordance with the real deceleration curve. The method also includes a step of exerting a braking force on the crash-test carriage in a direction opposite the acceleration direction in order to achieve a desired acceleration curve. The braking force is applied on one of the crash-test carriage and the carriage drive apparatus, the braking force being so large so as to accelerate the crash-test carriage in accordance with the desired acceleration curve.Type: GrantFiled: July 30, 2002Date of Patent: January 13, 2004Assignee: DSD Dr. Steffan Datentechnik Ges. m.b.H.Inventors: Hermann Steffan, Andreas Moser, Manfred Hofinger, Bertram Christian Geigl, Erich Mayrhofer, Heinz Hoschopf, Stefan Winkler, Kurt Steiner
