  • Publication number: 20150223955
    Abstract: An implant delivery system is disclosed which includes an inner tube assembly, an outer tube assembly and a functional handle. The functional handle includes a threaded rod, a push-pull control member, a casing tube, a displacement tube, an inner tube fixing member, an outer tube fixing member and a stability tube fixing member. The threaded rod extends through a bore of the displacement tube. A fastener of the push-pull control member is able to engage a thread provided on a leading portion of the threaded rod. A trailing portion of the threaded rod is provided with a knob. The push-pull control member includes a fastener, springs and a button. The fastener is able to extend through a slot to engage a thread of the threaded rod in the displacement tube.

  • Patent number: 8270469
    Abstract: A method and related system of encoding or re-encoding video is disclosed. In the method, video data comprising a sequence of frames is received. For a respective frame in the sequence of frames, a multi-level frame is generated comprising the respective frame and a plurality of copies of the respective frame. Each copy has an associated video resolution level that is a member of a predefined range of video resolution levels, ranging from a highest video resolution level to a lowest video resolution level. The multi-level frame is encoded.

  • Patent number: 8238419
    Abstract: A method of displaying video includes receiving a video bitstream corresponding to a video. The video comprises a sequence of frames having an associated video resolution level. At least a portion of the video bitstream is decoded. A background region of the video is displayed at a first video resolution level and a window region of the video is displayed at a second video resolution level. The second video resolution level is higher than the first video resolution level.

  • Publication number: 20090320081
    Abstract: A method provides video from a video data source comprising a sequence of multi-level frames. Each multi-level frame comprises multiple copies of a respective frame. Each copy has an associated video resolution or quality level that is a member of a predefined range of levels that range from a highest level to a lowest level. First video data corresponding to a first portion of a first copy of a respective frame and second video data corresponding to a second portion of a second copy of the respective frame are extracted from the video data source. The video resolution or quality level of the second copy is distinct from that of the first copy. The first and second video data are transmitted to a client device for display. The extracting and transmitting are repeated with respect to successive multi-level frames of the video data source.
