  • Publication number: 20120260298
    Abstract: The present invention provides method and system for sharing video among mobile terminals. The method comprises: a calling terminal uploads a video file to a media server; a called terminal establishes a video link with the media server through a mobile network; the media server sends a video stream to the called terminal through the video link; the called terminal receives the video stream from the media server and plays the video file. The method and system provided by the present invention enable simultaneous sharing of the same video among multiple called terminals and enable a called terminal to watch the same shared video multiple times, therefore not only time and labour are saved, but also user experience is enhanced. By playing shared video through a mobile network, stream media is played directly and more smoothly, and problems of video buffering and video stagnating in video sharing are solved.

  • Patent number: 7195901
    Abstract: The gene for the diacylglycerol acyltransferase (DGAT) from Ricinus communis L., the castor plant, has been isolated, cloned, and used to transform other plants and micro-organisms. When the gene is expressed in a heterologous system, the corresponding DGAT protein is active and shows unusual and selective action for hydroxylated fatty acyl glycerides. DGAT carries out the final step in castor oil biosynthesis, and is believed to be largely responsible for many of the attributes of castor oil, making it an excellent candidate for industrial uses. This invention makes it possible to enhance the oil-producing capacity of other plants and micro-organisms.
