Patent CA-2366814-A1 (CA)
Title: Stent delivery system using shape memory retraction
Inventor: VRBA ANTHONY C
IPC: A61F2/06
Filed: 2000-03-24
Abstract: The inventive stent delivery system includes a catheter having a retractable outer sheath near its distal end. A shape memory contraction member having a memorized contracted shape is connected to the retractable outer sheath. A heat generating device connected to the shape memory contraction member causes the shape memory contraction member to heat up to its transition temperature and assume its contracted position, retracting the retractable outer sheath. Another embodiment utilizes 2 springs, a"normal" spring and a shape memory alloy (SMA) spring, the two springs selected and designed so that the "normal"  has an expansion force which is less than SMA spring when the SMA spring is austenitic, but greater than the SMA spring when the SMA spring is martensitic. Yet another embodiment utilizes a shape memory latch which in its martensitic state abuts a stop to prevent a spring from moving the sheath proximally, but in its austenitic state releases the stop, allowing the spring to retract the sheath to release the stent for deployment.

Title: High-stiffness propylene polymers and a process for the preparation thereof
Inventor: VESTBERG TORVALD
IPC: B65D65/02
Filed: 2000-05-08
Abstract: The present invention concerns high-stiffness polymer composition and a process for producing a polymer composition nucleated with a polymeric nucleating agent containing vinyl compound units. The method comprises modifying a catalyst by polymerizing a vinyl compound in the presence of sai d catalyst and a strongly coordinating donor in a medium, which does not essentially dissolve the polymerized vinyl compound, and by continuing the polymerization of the vinyl compound until the concentration of unreacted vinyl compounds is less than about 0.5 wt-%. The thus obtained modified catalyst composition is used for polymerizing propylene optionally together with comonomers in the presence of said modified catalyst composition. Modification of the catalyst according to the present invention will reduce production costs and provide highly reliable catalyst activity and polymers of high stiffness.

Title: Vibration damping system for esp motor
Inventor: PARMETER LARRY JAMES
IPC: H02K7/08
Filed: 2002-03-06
Abstract: Arrangements are described wherein fluid is supplied under pressure to lubricate and replenish the fluid film located between the rotating, inner bearing sleeve and the outer, stationary sleeve insert of the bearing assemblies of a motor. The sleeve insert is provided with fluid metering passages that permit lubricating fluid to pass through the body of the sleeve insert. The sleeve insert is disposed radially within a sleeve insert holder, and a fluid gap is defined between the two components. During operation, vibration of the rotor shaft within the stator bore is damped by the fluid spring created by the metering of fluid through the sleeve insert. As a result, friction is reduced and the lifespan of the motor increased.

Title: System and method for achieving robust ip/udp/rtp header compression in the presence of unreliable networks
Inventor: KOODLI RAJEEV
IPC: H04L29/06
Filed: 2000-12-22
Abstract: A robust IP/UDP/RTP header compression mechanism is provided to correctly reconstruct IP/UDP/RTP headers in the presence of packet losses and errors of unreliable networks. The header compression mechanism may include a compressor/decompressor implemented for operation similarly to RFC 2508 but designed specifically to address robustness when employed in lossy and error-prone networks. The robust header compression scheme requires that, when a second-order difference of a field is non-zero, not only a particular RTP packet whose second-order difference is non-zero is sent with the new first-order difference, but also those following packets are also sent with the new first-order difference as long as: (a) a pediod pre-determined by factors such as channel characteristics (e.g., link round-trip time RTT/inter-packet separation); or (b) a positive confirmation is received by the compressor that the new first-order difference has been correctly received. In addition, during a period of communicating with the new first-order difference, if the corresponding RTP field changes again with non-zero second-order difference, the "new" first-order difference is combined with the original first-order difference such that the two first-order differences may be appended together as a simple means of communicating the two-order differences reliably.

Filed: 2001-03-13
Abstract: A method for protecting the surface of a semiconductor material (30, 50) from damage and dopant passivation is described. A barrier layer (32, 52) of dense or reactive material is deposited on the semiconductor material shortly after growth in a growth reactor (10) such as a MOCVD reactor, using the MOCVD  source gasses. The barrier layer (32, 52) blocks the diffusion of hydrogen into the material. The reactor (10) can then be cooled in a reactive or non-reactive gas ambience. The semiconductor material can then be removed from the reactor (10) with little or no passivation of the dopant species. The barrier layer (32, 52) can be removed using a variety of etching processes, including wet chemical etching or can be left at the semiconductor material for surface protection. The barrier layer (32, 52) can also be a gettering layer that chemically binds hydrogen trapped in the semiconductor material and/or blocks hydrogen diffusion into the material.
