Publication number: 20240127470Abstract: In a method of predicting a position of an object at a future time point for a vehicle, video image information at a current time point and at a plurality of time points before the current time point acquired through a camera of the vehicle may be extracted as semantic segmentation image. A mask image imaging an attribute and position information of an object present in each of the video images may be extracted. A position distribution of the object may be predicted by deriving a plurality of hypotheses for a position of the object at a future time point through deep learning by receiving video images at the current time point and the time points before the current time point, a plurality of semantic segmentation images, a plurality of mask images, and ego-motion information of the vehicle, and calculating the plurality of hypotheses as a Gaussian mixture probability distribution.Type: ApplicationFiled: March 23, 2023Publication date: April 18, 2024Applicants: HYUNDAI MOTOR COMPANY, KIA CORPORATION, Ewha University - Industry Collaboration FoundationInventors: Hyung-Wook Park, Jang-Ho Shin, Seo-Young Jo, Je-Won Kang, Jung-Kyung Lee

Patent number: 8107865Abstract: An image forming apparatus including a fixing device having first and second rollers to press against each other with a sheet of paper to be transferred therebetween. The apparatus includes a roller frame to support the first roller; a separation claw, which, when disposed in an operational position on an outer circumferential surface of the first roller, separates the sheet of paper from the first roller; a claw frame to support the separation claw, which is movably attached to the roller frame to allow the separation claw to move between the operational position and a withdrawal position, at which the separation claw is withdrawn from the operational position; and an elastic member coupled between the claw frame and the roller frame, to bias the claw frame such that biasing force applied to the claw frame causes the separation claw to move from the withdrawal position to the operational position.Type: GrantFiled: June 16, 2010Date of Patent: January 31, 2012Assignee: Samsung Electronics Co., Ltd.Inventor: Seo-won Park

Patent number: 6739051Abstract: A pressure roller for a fixing device is manufactured by extruding silicone rubber on a shaft, foaming the extruded silicone rubber, subjecting the foamed silicone rubber to primary and secondary heat treatments, polishing the heat-treated silicone rubber, and then disposing the polished silicone rubber in a resin tube. In accordance with one embodiment, the pressure roller includes a shaft, a first silicone rubber layer formed on the shaft so as to surround the shaft, a resin tube formed on the first silicone rubber layer so as to surround the shaft, the resin tube having extensions at opposite ends thereof, each extension extending beyond the opposite ends of the first silicone rubber layer, and second silicone rubber layers formed at respective opposite ends of the first silicone rubber layer between the extensions of the resin tube and the shaft. The second silicone rubber layers serve to couple the first silicone rubber layer to the resin tube.Type: GrantFiled: October 22, 2001Date of Patent: May 25, 2004Assignee: Samsung Electronics Co., Ltd.Inventor: Seo-Won Park
