Patent number: 11948722Abstract: A planar winding transformer includes a magnetic core set and a multilayer circuit board. The magnetic core set includes two magnetic cores and two magnetic columns. The two magnetic cores are parallel to each other. The multilayer circuit board is disposed between two magnetic cores, and two magnetic columns penetrate through the multilayer circuit board. The multilayer circuit board includes two low voltage winding layers and one high voltage winding layer. Two low voltage winding layers are connected to each other in parallel, and the high voltage winding layer is disposed between two low voltage winding layers. When the high voltage winding layer receives a polarity current, at least one of the low voltage winding layers generates a corresponding induced current. Two magnetic cores and two magnetic columns form a closed path for magnetic flux.Type: GrantFiled: January 8, 2021Date of Patent: April 2, 2024Assignees: CHICONY POWER TECHNOLOGY CO., LTD., NATIONAL TAIPEI UNIVERSITY OF TECHNOLOGYInventors: Yen-Shin Lai, Yong-Yi Huang, Chun-Hung Lee, Hao-Chieh Chang

Patent number: 8629901Abstract: A method of revising depth of a three-dimensional (3D) image is disclosed. The method comprises the following steps: firstly, at least one initial depth map associated with one image of the 3D image pair based on stereo matching technique is received, wherein the one image comprises a plurality of pixels, and the initial depth map carries an initial depth value of each pixel. Then, the inconsistence among the pixels of the one image of the 3D image pair is detected to estimate a reliable map. Finally, the initial depth value is interpolated according to the reliable map and the proximate pixels, so as to generate a revised depth map by revising the initial depth value.Type: GrantFiled: May 19, 2011Date of Patent: January 14, 2014Assignee: National Taiwan UniversityInventors: Liang-Gee Chen, Chien Wu, Chung-Te Li, Yen-Chieh Lai, Chao-Chung Cheng, Ling-Hsiu Huang
