Title: Distinguishing between link and node failure to facilitate fast reroute
Inventor: CHARNY ANNA
IPC: H04L12/56
Filed: 2003-06-06
Granted: 2010-04-27
Abstract: System and methods for distinguishing a node failure from a link failure are provided. By strengthening the assumption of independent failures, bandwidth sharing among backup tunnels protecting links and nodes of a network is facilitated as well as distributed computation of backup tunnel placement.  Thus a backup tunnel overlay network can provide guaranteed bandwidth in the event of a failure.

Title: Apparatus and method for transcervical sterilization by application of ultrasound
Inventor: RYAN THOMAS P
IPC: A61B18/12
Filed: 2003-06-18
Granted: 2012-08-07
Abstract: An apparatus for sterilizing a female patient in a transsevical procedure comprises an elongated catheter with a piezoelectric ultrasound transducer at its distal end. The catheter is inserted transcervically into the uterus and guided to the intramural region of a fallopian tube. The transducer is inserted into the intramural region in direct contact with the surrounding tissue. The transducer produces a radially dispersing acoustical wave front, heating the adjacent tissue and forming a thermal lesion therein. A fibrous tissue forms during the healing process, sealing the fallopian tube. An embodiment of the apparatus includes a movable thermal sensor for monitoring the tissue temperature at multiple locations along the lesion. Another embodiment of the apparatus includes a spring that centers the distal end of the catheter at the opening of the fallopian tube and provides a tactile means to determine that the catheter and transducer have been correctly positioned.

Abstract: Cette invention concerne des anticorps désimmunisés qui sont utilisés comme médicaments immunothérapeutiques contre le virus de l'immunodéficience humaine (VIH) et les troubles autoimmuns induits par CD4. De manière plus spécifique, des anticorps exprimés par des clones, à savoir le clone 7 contenant les gènes recombinants B4DIVHv1/VK1CHO#7, le clone 16 contenant les gènes recombinants B4DIVHv1/VK1#16 et le clone 21 contenant les gènes recombinants B4DIVHv1/VK1#21, sont dérivés de l'anticorps B4 monoclonal de souris (mAb B4). Ces anticorps sont produits par la suppression de certains déterminants murins considérés comme étrangers par le système immunitaire humain. Ces anticorps recombinants sont générés par la chimérisation et la désimmunisation de la région Fv de l'anticorps monoclonal de souris (mAb) B4. Pour plus de sécurité, la séquence codante peut également être mutée de façon qu'elle exprime un anticorps IgG¿1? non glycosylé qui est incapable de fixer le complément. Les anticorps désimmunisés conservent la spécificité de l'anticorps mAb B4 murin pour un complexe récepteur impliquant CD4 sur la surface des lymphocytes T hôtes et conservent la capacité caractéristique de l'anticorps mAb B4 à neutraliser les isolats primaires du VIH.
