Patent number: 11974367Abstract: A lighting device includes a light board and a light dimmer circuit. The light board includes multiple first light emitting elements and second light emitting elements. The first light emitting elements are disposed in a first area of the light board. The second light emitting elements are disposed in a second area of the light board. The light dimmer circuit is configured to drive the second light emitting elements to generate flickering lights from the second area of the light board, and is configured to drive the first light emitting elements to generate non-flickering lights from the first area of the light board.Type: GrantFiled: October 4, 2022Date of Patent: April 30, 2024Assignee: DELTA ELECTRONICS, INC.Inventors: Chih-Hsien Wang, Ming-Chieh Cheng, Po-Yen Chen, Shih-Chieh Chang, Kuan-Hsien Tu, Xiu-Yi Lin, Ling-Chun Wang

Patent number: 8599449Abstract: Disclosed is a system and method for capturing technical documents and reading and commentating captured documents thereof. The system may comprise a capturing system and a reading with commentating system. The capturing system selects related drawings from a group of technical documents. It then provides important information and the related drawings onto an image for the readers' review. The reading with commentating system allows the readers to process technical classification, management and export/import for the group of technical documents. Readers may make comments on an information sharing platform after reviewing the technical documents. Besides, other materials collected or generated from the technical analysis on the technical documents may be attached to the information sharing platform.Type: GrantFiled: January 6, 2013Date of Patent: December 3, 2013Assignees: Industrial Technology Research Institute, Chao-Chin ChangInventors: Chen-Kun Chen, Yu-Chen Yu, Mu-Tao Chu, Kuan-Chieh Tu, Chao-Chin Chang, Hsiao-Wen Chang, Chen-Peng Hsu

Patent number: 7988339Abstract: An illumination system includes at least one illumination module and a mechanism. The illumination module includes a light source generating a light beam, a first reflector, in which the light source is positioned, including a first reflective surface to reflect the light beam to form a first beam, and a second reflector including a second reflective surface reflecting the light beam and the first beam to form a second beam and a third beam, wherein the second and third beams combine to generate a projection pattern. The mechanism adjusts the position of the second reflector relative to the light source to change the projection pattern.Type: GrantFiled: April 24, 2009Date of Patent: August 2, 2011Assignee: Industrial Technology Research InstituteInventors: Ya-Hui Chiang, Cheng-Da Shaw, Hung-Lieh Hu, Kuan-Chieh Tu
