Webkit, as an open-source browser engineer, has higher speed, less memory and other notable features. In the paper, introduced the framework of Webkit and the Linux browser-related techniques, studied the core models and improved the function of Web kit by object WebKitWebView and locale setting, made it support Multi-window display and Chinese pages, realized the basic uses of browser. When it runs, it costs less resource, having the higher speed of image rendering. This Linux browser will have a good application prospects.

We propose a novel optical bistable device (OBD) in frequency-domain with which we can perform optical bistable operations in a number of fibre Bragg gratings (FBGs) which are included in the same OBD. Such an OBD may bring more opportunities in applications and, as an example, we show the possibility of using it in an FBG sensor demodulating system. By use of a tunable light source, consisting of a broad band source and a scanning fibre F–P (FFP), we demonstrate the above-mentioned operations experimentally.
