Patent number: 8377503Abstract: A method for real-timely monitoring thickness change of a coating film is disclosed. In the method, a coating module having a chamber and a film thickness-monitoring module containing an SPR optical fiber sensor, a light source, a light-receiving detector, and optical fibers are first provided. The optical fibers are used to connect the SPR optical fiber sensor with the light source and the light-receiving detector. The SPR optical fiber sensor has a sensing area and is arranged in the chamber. The light source provides the SPR optical fiber sensor with light. Then, a substrate is put into the chamber. While coating process is performed on the substrate, a film is also formed on the sensing area of the SPR optical fiber sensor. The light-receiving detector receives signals output from the sensing area of the SPR optical fiber sensor and then outputs signals of light-intensity change.Type: GrantFiled: April 22, 2010Date of Patent: February 19, 2013Assignee: Forward Electronics Co., Ltd.Inventors: Yu-Chia Tsao, Chung-Pei Lee, Ko-Shao Chen, Jia-Huey Tsao, Chun-Chih Lin, Ren-Kun Liang

Patent number: 6022330Abstract: A novel method of preparation of easily stripped off temporary wound dressing material is disclosed. In this process, the-N-isopropyl acrylamide (NIPAAm) monomer is successfully grafted on the non-woven cloths by copolymerization. It is initiated by .gamma.-ray irradiation to activate the surface of the non-woven cloth. NIPAAm is then grafted onto the surface of the non-woven cloth. The free radical or peroxide is produced by Co-60 .gamma.-ray, then grafted on the non-woven cloths. The lower critical solution temperature (LCST) in thermoresponsive poly-N-isopropylacrylamide (NIPAAm) is still retained after the grafting. This will make the dressing cloth stripped off easily and without hurting the tissue. The material process is very simple and has medically applicable value.Type: GrantFiled: June 23, 1997Date of Patent: February 8, 2000Assignee: Institute of Nuclear Energy Research, Taiwan, R.O.C.Inventors: Chia-Chieh Chen, Ko-Shao Chen, Te-Hsing Wu, Ching-Hohn Len, Zei-Tsan Tsai, Bin Lin
