    Abstract: A method for measuring fundamental mode cutoff wavelength of single polarization fiber comprising: (i) launching pulsed light of at least one wavelength λi into one end of the single polarization fiber; (ii) measuring backscattered light intensity corresponding to said wavelength to obtain the backscattered light intensity as a function of fiber position, wherein the backscattered light propagates through the same end of the fiber; and (iii) determining at least one cutoff wavelength and the corresponding position within said fiber for the cutoff wavelength, based on a specified threshold light intensity level.

    Abstract: This invention provides a method that when the disturbance of the bandwidth or the signal quality occurs during the digital program broadcasting, so that the broadcasting quality of the currently broadcast normal program is below a predetermined value, a prearranged program having a specific broadcasting quality, such as advertisements, will be inserted. The prearranged program may have an regular relation to the currently broadcast normal program, thereby the user would rather appreciate some program than suffer bad screen showing or wait until the program returns back to a good condition to be watched normally. This invention further provides a method for making statistics of the inserted prearranged program, said statistical information could be used for charging.

    Abstract: The present invention provides a method for creating an electronic bookmark during browsing on a web. According to a predetermined sequence the method records the process of browsing the specific program content by an user and stores the process in a storing means. The stored content is a browsing command for requiring a specific server to send the program content from an random position in a specific program specified by an user. When a user clicks the bookmark, a series of requests contained in the bookmark are handled one by one in the batch-handling manner, so that the user can directly and accurately find the specific position in the specific program in a on-line manner in the web, as conveniently as using conventional bookmarks in the conventional books.
