Title: Improved abdominal postoperative binder and method of use
Inventor: MOTT GEORGE E
IPC: A61F5/24
Filed: 2001-06-11
Abstract: The invention is a postoperative binder and method of use. The binder is made of relatively inelastic material that is cut to fit the patient and held in place by a plurality of tails fastened with binders. The present invention uses mechanical, rather than elastic, compression. Mechanical loads are carried over the iliac crest, by hooking the tails of the binder over the iliac crest and then bifurcating the tails for attachment to the abdominal portion of the binder. The present invention provides support of lower abdominal tissue, especially near the genitals and in the area of the peritoneum. Cut out (117) defines an anal opening in the binder. Cut outs (128, 129) define leg openings, together with tails (105, 107). End (135) of the binder is shown under and attached to the ends of tails (105, 107).

Title: Compositions and methods for modulating rsv infection and immunity
Inventor: JONES LES
IPC: A61K38/00
Filed: 2001-10-18
Abstract: Compositions and methods are provided for the treatment or prevention of RSV  disease by modulating RSV infection and immunity. In particular, amino acid sequences in the RSV G glycoprotein, containing the chemokine motif defined as C-X-X-X-C (or CX3C), are identified that are essential in causing RSV  infection and disease. The chemokine motif is biologically active and participates in virus binding to and infection of susceptible cells. The prevention or treatment of RSV infection is achieved by interfering with the motif, such as by administering a vaccine in which the motif is altered or by administration or induction of blocking molecules that inhibit the biological activity of the motif.

Abstract: A method of handlebar stem adjustability on a threadless steering tube bicycle steering assembly and a threadless steering tube bicycle steering assembly. A first step involves providing a cylindrical bushing having a first end, a second end, and a longitudinal slit which extends between the first end and the second end. A second step involves positioning the cylindrical bushing overlying a steering tube in close fitting relation and extending for length equal to a length by which the steering tube extends past an upper bearing. A third step involves tightening a top cap onto the steering tube to clamp down upon the cylindrical bushing to produce compression on the upper bearing. A fourth step involves clamping a stem clamp of a handle bar stem onto the cylindrical bushing, thereby causing the cylindrical bushing to frictionally engage the steering tube.

Title: Gravity gradiometry
Inventor: VAN KANN FRANK J
IPC: G01V7/16
Filed: 2001-11-27
Abstract: A gravity gradiometer is combined with a two-stage actively controlled isolation system. The gravity gradiometer and two stage isolation system may then be mounted within (or on) a mobile vehicle such as, for example, an aircraft. It has been recognised by the inventors herein that the accelerations imparted to an aircraft during normal operations can be separated through system design into two relatively distinct regimes within the frequency domain. The invention provides a first isolation mount, which forms part of the isolation system, to isolate accelerations (and resulting translations) falling within a first of the two frequency regimes. The second isolation mount, which is mounted to the first isolation mount, isolates accelerations falling within the second of the two frequency regimes. A  gravity gradiometer can then be mounted to the second isolation mount. As a result of housing the gravity gradiometer within the nested isolation system (a combination of the first and second isolation mounts), the gravity gradiometer is substantially isolated from the accelerations experienced by the mobile vehicle. Consequently, gravity gradients measured by the gravity gradiometer are relatively noise free and provide heretofore-unobtainable accuracy.

Abstract: L'invention concerne un procédé de fabrication d'un textile stratifié non tissé, qui consiste à déposer une première couche non tissée sur un support mobile, à déposer une seconde couche non tissée sur la première couche et à acheminer les couches sous un collecteur. Ce dernier comporte plusieurs groupes de jets séparés les uns des autres par une distance. L'eau est dirigée des groupes de jets sur les couches sous-jacentes afin de créer un textile stratifié. Du fait que les groupes de jets sont séparés les uns des autres, le textile stratifié présente un <= enchevêtrement de modèles >=. La formation de faisceaux s'effectue le long de lignes sensiblement linéaires, la formation étant moins dense dans des zones situées entre les zones de formation de faisceaux linéaires. On obtient ainsi un textile doté de zones présentant un enchevêtrement relativement important et d'autres zones présentant un enchevêtrement beaucoup plus faible. Lorsque trois couches sont stratifiées, les couches inférieure et supérieur étant en placage et la couche centrale en pâte, le présent procédé permet d'obtenir un textile stratifié doté d'une utilité particulière comme produit de nettoyage jetable dans les toilettes.

Title: Multi-path dynamic routing algorithm
Inventor: PLOTKIN SERGE
IPC: H04L12/56
Filed: 2001-05-22
Abstract: This invention relates to the field of data network routing. More particularly, this invention is a method for routing data in networks where processing speed is a limiting factor by using a new measure of merit, terme d a node metric. With reference to Fig. 2, the nodes (210) in the network (200 ) are characterized by their limited bandwidths. Each node (210) can communica te with only one other node (210) at a time via communication links (220). The sum of the traffic rates on the links (220) of a node (210) is limited by th e capacity of the node (210). For each node (210) a node metric is computed based on factors such as future traffic to and from the node (210). For any path between any two nodes (210), a path metric, which represents congestion , is computed as the sum of the node metrics of the nodes (210) along the path . Path metrics are then used for routing of the traffic through the network.</ SDOAB>
