    • An optical fiber system that includes an in-fiber optic component powered by in-fiber light includes an optical fiber having a core, wherein the optical fiber propagates a sensing/signal light and a power light, with the sensing/signal light being propagated in the core. An optical transducing element, such as a layer of light absorbing material, is located in proximity to the in-fiber optic component. An optical tap region is provided in the optical fiber in proximity to the optical transducing element, and enables the power light to leak from the optical fiber and be absorbed by the optical transducing element. The optical transducing element converts the absorbed power light into a second energy form, such as heat, which is used to tune the in-fiber optic component.

    • This invention provides a flexible polymer modified waterproofing cement material which can be used on a substrate or in concealed areas of construction engineering, water conservancy projects, municipal works, and its making process. The waterproofing material is made by kneading a hydraulic cement, a polymer dispersion, a water-soluble polymer or re-dispersible resin and water at a weight ratio of cement/polymer of about 100:15 to about 100:150 under conditions of about 25° C. to about 120° C., about 20 rpm to about 80 rpm until the water content of the kneaded materials reaches about 5% to about 20%. The kneaded material is mixed with a toughening polymer at a weight ratio of about 100:10 to about 100:50, then is calendered into sheets. These materials can adhere to dry or wet substrates firmly. They can be used in cold or hot and wet climate areas. After application, the waterproofing structure formed can bear retractive stress and deformation of the base or can resist outer impact.
    • 本发明提供一种柔性聚合物改性防​​水水泥材料,可用于建筑工程,水利工程,市政工程及其制造过程的基材或隐蔽区域。 该防水材料是通过在大约25的条件下捏合水硬性水泥,聚合物分散体,水溶性聚合物或再分散树脂和水,其重量比为约100:15至约100:50的水泥/聚合物 约20℃,约20rpm至约80rpm,直到捏合材料的水含量达到约5%至约20%。 捏合的材料以约100:10至约100:50的重量比与增韧聚合物混合,然后压延成片。 这些材料可以牢固地粘附在干燥或湿的基材上。 它们可用于寒冷或潮湿和潮湿的气候区域。 应用后,形成的防水结构可承受基座的回缩应力和变形,或可抵抗外部冲击。
