Title: Method and apparatus for transmitting mpeg video over the internet
Inventor: BOYCE JILL MACDONALD
IPC: H04N7/24
Filed: 1999-09-02
Abstract: In order to transmit an inter-frame coded video signal, such as an MPEG-coded video signal, over a packet-based network such as the Internet, the video signal associated with at least one video frame, is split into a high priority partition and a low priority partition. A systematic forward error/erasure correction (FEC) code, such as a Reed Solomon (n,k) code, is then applied to bytes in the high priority partition. The forward error/erasure corrected high priority partition information bytes and the low priority partition information bytes are then combined into n packets for transmission over the packet network to a receiver/decoder. Each of the n transmitted packets contains a combination of both high priority partition data bytes and low priority partition information bytes. In k of those packets the high priority partition data bytes are all high priority partition information bytes and in n-k of those packets all the high priority partition data bytes are parity bytes produced by the FEC coding. More specifically, for each high priority partition information byte position within the n packets, the forward error/erasure correction code is applied using one high priority partition information byte from the same byte position in each of those k packets to determine n-k parity bytes, which are arranged, one byte per packet, in the n-k packets containing high priority partition parity bytes. If up to n-k packets are lost in transmission over the packet network to the receiver, then the high priority partition information bytes in such lost packets can be recovered to applying FEC decoding to the high partition bytes in the received packets. The most visually significant information is thus protected against packet loss over the network.

Title: Immobilized activity stabilized lhrh antagonist complexes, method for the production thereof
Inventor: LOSSE GUENTER
IPC: A61K38/09
Filed: 1998-03-11
Abstract: The invention relates to a retard system for LHRH  antagonists, specially cetrorelix, based on complexation with suitable biophile carriers enabling targeted release of the active substance over a period of several weeks.  Acidic polyamino acids, polyasparaginic acids and polyglutaminic acids are selected for complexation with cetrorelix. The cetrorelix polyamino acid complexes are produced from aqueous solutions by combining the solutions and precipitating the complexes which are subsequently centrifuged off and vacuum dried by P2O5, lyophilization proving to be a suitable method. The acidic polyamino, polyglutaminic and polyasparaginic acids display good retarding properties in a static liberation system depending on the hydrophobicity and the molar mass of the polyamino acids. Animal testing demonstrates the principal efficacy of the cetrorelix polyamino acid complexes as a depot system. By complexation of cetrorelix with polyamino acids, testosterone suppression can be achieved in male rats over a period of 600 hours. Active substance release can thus be controlled according to polymer type and molar mass.

Title: Radially expandable nickel-titanium surgical stent
Inventor: FRANTZEN JOHN J
IPC: A61F2/915
Filed: 1998-09-29
Abstract: A radially expandable surgical stent is provided formed from a shape memory and/or superelastic material such as a nickel-titanium alloy. The stent includes a series of wave-like struts spaced apart by gaps. Each gap is spanned by tie bars at a maximum width portion of the gap or by an angled link or a straight link at a minimum width portion of a gap. Hence, axial expansion or contraction of the stent is avoided when the stent is radially expanded or contracted. Each strut is formed from a series of substantially linear legs joined together by free bends or attachment bends. The legs and bends can be provided with an enhanced thickness to augment resistance of the stent to fracture when radially expanded or contracted. The stent can be radially contracted to a diameter less than one-fourth of its radially expanded configuration when in a martensite phase. The stent returns to a shape memory austenite phase when the stent is unloaded or loaded below its yield strength and has a temperature above its transition temperature. The stent can thus be easily collapsed and implanted within a body lumen for later radial expansion to support the body lumen.
