Title: Wireless telecommunications system and method for designing same
Inventor: KHANNA SANJEEV
IPC: H04W16/18
Filed: 1999-03-02
Abstract: A method for designing a wireless telecommunications system having a plurality of cells is provided. In one embodiment of such a method, a call demand per cell is estimated, and a channel demand based thereon is determined on a cell-by-cell basis. The cell-by-cell channel demand is used to provide a reasonably tight upper bound on the number of communication channels required to satisfy the system-wide call demand. It is implicit in the procedure for estimating the upper bound that no mutually "interfering" base stations use the same channel (i.e., frequency). "Cliques"  of mutually-interfering base stations or cells are defined. A channel demand is determined for each clique by adding up the channel demand for each cell in the clique.  The greatest channel demand of all cliques determines a "maximum clique demand"  .omega. d. The upper bound on the number of channels required to satisfy the system-wide call demand is given by the expression: X d ~ 17/12 ~ w d when mutually-interfering cells are adjacent cells, and is given by the expression: X d ~ 2 ~ .omega. d min when mutually interfering cells are adjacent cells and next-to-adjacent cells, wherein d min is a minimum channel demand of all cells in the system. Having a reasonably-good estimate of the upper bound on the system-wide channel requirement, a wireless service provider may then seek to obtain or allot a commensurate amount of frequency spectrum to support its system.

Title: Dialysis catheter having rigid and collapsible lumens and related method
Inventor: PALESTRANT AUBREY M
IPC: A61M25/00
Filed: 1997-11-26
Abstract: A multiple-lumen catheter (10) includes a first generally-cylindrical flexible lumen (12) extending between a first distal end (14) and a second proximal end (16); the first lumen is sufficiently rigid to maintain its generally-cylindrical shape when negative pressure is applied thereto for aspirating fluid from the blood vessel. A second flexible lumen (18) also extends between a first distal end (20) and a second proximal end (22) alongside the first lumen. The first distal end of the second lumen is sufficiently pliable to collapse and flatten in the absence of any positive fluid pressure applied to the second lumen; upon the application of a positive fluid pressure to the second lumen, the collapsible first distal end of the second lumen expands and assumes a generally-cylindrical shape for introducing fluid into the blood vessel. The first collapsible end of the second lumen can extend beyond the first non-collapsible end of the first lumen for introducing fluid into the blood vessel through the second lumen at a point spaced apart from the first end of the first lumen. In hemodialysis applications, the first lumen is used to aspirate blood, and the second lumen is used to return cleansed blood.

Abstract: A process for preparing a multilayered foam article such as an automotive seat is disclosed. A mold is arranged so that the bottom surface of the mold is flat or inclined up to 40 degrees to the horizontal plane. The first liquid foam formulation designed to produce a soft foam is poured into the mold from a mixing head outlet strip-wise across the seating zone of the mold along the line parallel to but near the external wall of the seating zone of the mold. Then, the second liquid foam formulation designed to produce a hard foam is poured into the mold from the same or different mixing head outlet strip-wise across the seating zone of the mold along the line parallel to but nearer to the external wall of the mold than the line of pouring of the first liquid foam formulation. The second liquid foam formulation is then allowed to spread on top of the first liquid foam formulation, the mold is closed and the foames are allowed to rise and cure in the mold. The process produces an article having excellent layered-foam seating area.

Inventor: BOSWORTH BRAD T
IPC: C12Q1/6876
Filed: 1998-05-20
Abstract: The present invention provides non-invasive methods and compositions to differentiate, with a high level of sensitivity and specificity, swine that are genetically susceptible to diseases associated with F18 E. coli infection, from resistant swine. DNA polymorphisms in the swine alpha (1,2) fucosyltransferase 1 (FUT1) gene were used to differentiate resistant from susceptible swine. The invention includes a polypeptide with amino acid substitutions, encoded by the nucleotide polymorphisms, a molecular diagnostic assay, and a kit for the differentiation, of E. coli F18-adhesion resistant, heterozygous (carrier) and homozygous susceptible pigs. The molecular test identifies susceptibility to oedema disease and postweaning diarrhea with high sensitivity and specificity, therefore, is useful to swine breeders in their effort to enhance for resistance. Information on the polymorphisms of the present invention provides insight into causation and treatment of E. coli associated intestinal disorders.
