Publication number: 20120242827Abstract: An automated optical inspection system for the runout tolerance of circular saw blades comprises a rotating device, a first and a second optical inspection module, and a computing device. The rotating device is used to rotate a circular saw blade. The circular saw blade includes multiple teeth, and each tooth has a side and a back. The first/second optical inspection module is used to capture a side/back image of the tooth. The computing device activates the rotating device to rotate the circular saw blade, and activates the first and the second optical inspection module to capture the side image and the back image of each tooth upon rotation of the circular saw blade. The computing device performs a radial-position-calculating procedure according to the side images, to obtain an amount of radial runout, and performs an axial-position-calculating procedure according to the back images, to obtain an amount of axial runout.Type: ApplicationFiled: March 21, 2011Publication date: September 27, 2012Inventors: Wen-Tung Chang, Chih-Hsien Su, Dong-Xie Guo, Geo-Ry Tang, Fang-Jung Shiou

Patent number: 7858047Abstract: A fluidic device is provided for sealing a proper amount of fluid with a brittle material. By moving an adsorbate through an external adsorption force, the brittle material for pre-sealing is broken, and the fluid flows out to interact with the external environment to generate a pump reaction. In addition, the invention may also be used for storing a liquid reagent in a device for a long time. Thereby, the fluidic device can be made small and portable.Type: GrantFiled: September 1, 2008Date of Patent: December 28, 2010Assignee: Industrial Technology Research InstituteInventors: Kuo-Yao Weng, Chien-An Chen, Cheng-Yu Ko, Chih-Hsien Su, Nien-Jen Chou, Chih-Wen Yang

Publication number: 20080020471Abstract: A blood sugar detecting system using emission quantum dots is provided. A non-cyclodextran carbohydrate-containing molecule and a glucose-recognizing molecule respectively bind to an emission quantum dot and a light-absorbing molecule to form the blood sugar measuring system. When the non-cyclodextran carbohydrate-containing molecule and the glucose-recognizing molecule bind together to bring the emission quantum dot very close to the light-absorbing molecule, a fluorescence resonance energy transfer effect is happened between them. Glucose can compete with the non-cyclodextran carbohydrate-containing molecule for the binding site of the glucose-recognizing molecule to detect glucose concentration variation.Type: ApplicationFiled: February 7, 2007Publication date: January 24, 2008Inventors: Chi-Min Chau, Chih-Hsien Su, Hsiang-Yuan Huang, Yuh-Jiuan Lin
