Abstract: A method is proposed for producing a tampon (T) packaged in a protective sleeve made from a preform (V) which is preferably formed by winding a strip of fibrous non-woven material. The preform (V) is shaped to form the tampon in separate pressing stages by pressure forces acting on it from outside, and is individually packaged by providing it with a film sleeve (10) tightly enclosing the tampon (T) serving as a protective sleeve. In order to reduce the complexity involved in producing a tampon, and in particular a non-round tampon, to the point at which its is individually packaged in the protective sleeve, the substantially cylindrical preform (V) is already paced in the film sleeve (10) surrounding at least the external surface of the preform (V) before the final forming stage (15). The preform (V) including the film sleeve (10) surrounding it is then fed to the final stage (15), where it is formed between at least two pressing jaws (20a, 20b) which can be displaced relative to on another until it has assumed its final non-cylindrical shape.

Title: Self energized packer
Inventor: MURRAY DOUGLAS J
IPC: E21B33/12
Filed: 2007-01-18
Granted: 2011-01-11
Abstract: A packer or plug features a main sealing element (12) that swells after a delay long enough to get it into proper position. A sleeve (14) eventually goes away to let the well fluids at the main sealing element to start the swelling process until contact with the surrounding tubular or the wellbore is established. Other sleeves (18,20) that are disposed above and below the main sealing element preferably swell, but mainly in a longitudinal direction against the main sealing element to increase its contact pressure against the surrounding tubular or the wellbore. The longitudinally swelling members may also be covered to initiate their growth after the main sealing element has started or even completed its swelling action. The longitudinally swelling members can be constrained against radial growth to direct most or all of their swelling action longitudinally. Extrusion barriers above and below the main sealing element can optionally be used.

Title: System and method for thinning of scalable video coding bit-streams
Inventor: HONG DANNY
IPC: H04N19/89
Filed: 2007-02-16
Granted: 2014-12-02
Abstract: A system for videoconferencing that offers, among other features, extremely low end-to-end delay as well as very high scalability. The system accommodates heterogeneous receivers and networks, as well as the best-effort nature of networks such as those based on the Internet Protocol. The system relies on scalable video coding to provide a coded representation of a source video signal at multiple temporal, quality, and spatial resolutions. These resolutions are represented by distinct bitstream components that are created at each end-user encoder. System architecture and processes called SVC  Thinning allow the separation of data into data used for prediction in other pictures and data not used for prediction in other pictures SVC Thinning processes, which can be performed at video conferencing endpoints or at MCUs, can selectively remove or replace with fewer bits the data not used for prediction in other pictures from transmitted bit streams.

Abstract: The present invention relates to non-replicative recombinant retrovirus packaging cells able to grow in suspension in a serum-free medium. In particular, the present invention relates to a human embryonic 293SF-based cell line stably expressing gag and pol gene products from the murine Moloney leukemia virus (MLV) and either the feline RD114 env gene, the gibbon ape leukemia virus (GLV) env gene, or the amphotropic 4070Aenv gene. This particular combination allows the production of high titer of non-replicative retrovirus pseudotyped and prevents the recombination of plasmids. The recombinant retroviruses produced from these cells are safer and easier to produce for clinical use in gene therapy.
