Patent number: 7892632Abstract: This invention pertains to a product and a method for preparing same. The product is an electrically conducting metallized fibers and a non-conducting composite containing the metallized fibers. In a preferred embodiment, the product is a composite of metallized cellulose fibers disposed in an electrically non-conducting matrix. The method includes the steps of hydrating cellulose fibers to prevent absorption of chemical reagents; activating the cellulose surface of the fibers for metal deposition; removing from the fibers excess activator and reagents used in the activation; drying the fibers to a free-flowing condition whereby the fibers acquire the color of the activator by virtue of its deposition on the fibers; metallizing the fibers to deposit thereon a metal capable of absorbing electromagnetic radiation; drying the metallized fibers whereby they are free-flowing; and forming a composite composed of an electrically non-conductive matrix having dispersed therein the matallized fibers.Type: GrantFiled: September 30, 2004Date of Patent: February 22, 2011Assignee: The United States of America as represented by the Secretary of the NavyInventors: Daniel Zabetakis, Paul E Schoen, Michael A.

Patent number: 7883668Abstract: An optical gas concentration sensor and method for measuring blood gas based on the light adsorption sensing technique are disclosed. The optical gas concentration sensor comprises a light source, a photo detector, and a gas filtering membrane for separating the indicator and a liquid. A gas in the liquid diffuses to the indicator through the gas filtering membrane so as to change the color of the indicator due to the chemical reaction occurred between the indicator and the gas. Then, the photo detector receives the light passing though the reacted indicator from the light source. The gas concentration is determined based on pH-sensitive absorbance spectrum of the indicator.Type: GrantFiled: December 3, 2007Date of Patent: February 8, 2011Assignee: Chung Yuan Christian UniversityInventors: Shen-Kan Hsiung, Jung-Chuan Chou, Tai-Ping Sun, Nien-Hsuan Chou, Chih-Wei Lai
