Patent number: 8178892Abstract: A light-emitting diode (LED) chip having a micro-lens structure includes a light-emitting structure and a light guide lens. The light-emitting structure emits a light from a light-emitting surface upon being applied with a current, and the light guide lens is stacked on the light-emitting surface and used for emitting the light from a light guide surface of the light guide lens. The light guide surface has an annular ridge portion and a scatter region, such that the lights close to the central optical axis of the light-emitting surface (the region having the maximum light-emitting intensity) are deflected in a direction away from the central optical axis, and the lights far away from the central optical axis are deflected towards the central optical axis, so as to obtain a light with a uniform overall optical intensity.Type: GrantFiled: July 16, 2007Date of Patent: May 15, 2012Assignee: Industrial Technology Research InstituteInventors: Tien-Fu Huang, Shih-Hao Hua, Kuo-Chang Hu, Che-wei Su

Publication number: 20100322594Abstract: A method in a video playback system for playing a video with a specific playback speed in accordance with a video feature and a playback record is described. The system allows the playback record records a preceding playback speed corresponding to the video previously played to learn user preferences for a user. This makes the specific playback speed more suitable for the user without any adjustment. In addition, the system also allows the user input a resetting playback speed to actively adjust the specific playback speed if the original specific playback speed is not suitable for the user.Type: ApplicationFiled: March 19, 2010Publication date: December 23, 2010Applicant: National Taiwan UniversityInventors: Kai-Yin Cheng, Sheng-Jie Luo, Bing-Yu Chen, Hao-Hua Chu
