Abstract: A middle expanded, removable disk im-plant (22) with substantially rectangular cross--sectional shape with a minimal height (H) and a width (W) greater than the height which is de-tachably mounted to an applicator (52) for in-sertion into the anatomical region between two adjacent vertebrae (16, 18) from which a por-tion of the intervertebral disk has been removed.  The implant is positioned by anterior-posterior movement in the disk space to the position in which both the expanded middle portion and the smaller diameter end (25, 36) portions of the im-plant engage the bodies (12, 14) of the adjacent vertebrae and then rotated to bring the sides (34) of the implant defining the height of the implant into engagement with the bodies of the adjacent vertebrae. A lock (24) is then secured to the im-plant to prevent further rotation thereof. In the event the adjacent vertebrae need to be aligned before fusion, an elongate implant (112) is pro-vided which is split longitudinally into side-by-side members (113, 114) movable relative to each other and which is inserted into the disk space between two misaligned vertebrae (133, 137). The members are provided with teeth (138) for engaging the adjacent vertebrae and the implant formed by the two side-by-side members is rectangularly-shaped in cross section, the height (H6) of the rectangularly-shaped cross section being less than the width (W6) so that the implant can be inserted between the adjacent vertebrae with the lesser, height dimension oriented in the same direction as the axis of the spinal column and the larger width dimension at approximately a right angle to that axis.  One member is then moved relative to the other from the first side-by-side position along the longitudinal axis of the implant to a second position in which the members are aligned with the respective, adjacent, misaligned vertebrae and the implant is rotated 90° to engage the teeth to the bodies of the adjacent vertebrae. The two members are then brought back into the first side-by-side position to draw the vertebrae into alignment and the implant is rotated approximately 90°  to disengage the teeth from the vertebrae for removal from the disk space.

Title: Asthma associated factors as targets for treating atopic allergies including asthma and related disorders
Inventor: MALOY W LEE
IPC: C12N15/24
Filed: 1996-08-23
Abstract: A C to T DNA variation at position 3365 in exon 5 of the human Asthma Associated Factor 1(AAF1) produces the predicted amino acid substitution of a methionine for a threonine at codon 117 of AAF1. When this substitution occurs in both alleles in one individual, it is associated with less evidence of atopic allergy including asthma, fewer abnormal skin test responses, and a lower serum total IgE. Thus, applicant has identified the existence of a non-asthmatic, non-atopic phenotype characterized by methionine at codon 117 when it occurs in both AAF1 gene products in one individual.

Title: Fibre channel switching system and method
Inventor: RAMSAY PAUL
IPC: H04L12/56
Filed: 1998-03-19
Abstract: A modular Fibre Channel switch includes a data switching path and a message switching path to provide logical point to point connections between switch ports. The data switching path includes a bank of shared SRAM memory devices that are accessed in a time-sliced protocol by each switch port. A receiving switch port writes a data frame to the bank of shared SRAM and the transmitting switch port then reads the data frame from the shared SRAM thereby effecting the logical point to point connection. Because the switch port includes a frame logic circuit that allows for an arbitrary start of frame address, each frame can be written to the first available DRAM device thuseliminating the need to buffer the data frame while waiting for a predetermined DRAM device to cycle in the time sliced protocol. The message switching path includes a message crossbar switch that is barrel shifted in a time sliced fashion to effect message passing among the switch ports. The switch includes a motherboard containing an embedded G_Port ASIC, a message crossbar switch to handle message passing and shared memory that is used to perform data switching. The switch also includes acentral processing unit daughter board and external switch port daughter boards.

Title: Fuel cell
Inventor: TANIGUCHI SHUNSUKE
IPC: H01M8/02
Filed: 1998-04-14
Abstract: A current collector includes a thin porous substrate and a hydrophilic material, where the hydrophilic material is provided to holes of the thin porous substrate or surfaces of skeleton elements of the porous substrate so that hydrophilic areas formed by the hydrophilic material successively pass through the thin porous substrate between both surfaces of the thin porous substrate. In the current collector, water is let out through the hydrophilic areas and does not stay on an interface between an electrode and the current collector so that reaction gas is not hampered and is supplied, unlike a conventional current collector.      When the current collector is applied to a polymer electrolyte fuel cell, water is supplied with reliability through the hydrophilic areas to a polymer electrolyte membrane so that the polymer electrolyte membrane is effectively humidified. Tree current collector applied to a cathode achieves a profound effect because reaction product water tends to stay around a cathode of any types of fuel cells. The current collector also includes gas flow paths which are surrounded by particles of a hydrophobic material and pass through the thin porous substrate between both surfaces of the thin porous substrate. As a result, gas permeability of the current collector is maintained with reliability.

Patent CA-2244127-A1 (CA)
Title: Phrase recognition method and apparatus
Inventor: MILLER DAVID JAMES
IPC: G06F17/30
Filed: 1997-01-21
Abstract: A phrase recognition method breaks streams of text into text "chunks" and selects certain chunks as "phrases" useful for automated full text searching.  The phrase recognition method uses a carefully assembled list of partition elements (10) to partition the text into chunks, and selects phrases from the chunks according to a small number of frequency based definitions (20). The method can also incorporate additional processes such as categorization of proper names (30) to enhance phrase recognition. The method selects phrases quickly and efficiently, referring simply to the phrases themselves and the frequency with which they are encountered, rather than relying on complex, time-consuming, resource-consuming grammatical analysis, or on collocation schemes of limited applicability, or on heuristical text analysis of limited reliability or utility.
