Patent CA-2239957-A1 (CA)
Title: Fluorescence polarization immunoassay diagnostic method
Inventor: EDMONDS DAN M
IPC: G01N33/542
Filed: 1996-12-16
Abstract: A method for fluorescence polarization immunoassay (FPIA) involves adding to a fluid container one or more reagents and a sample whose analyte is to be detected and measured, and then taking a first polarization measurement of the sample. More reagent is then added to the sample in the container, with no further sample addition to the container. A second or final polarization measurement of the sample is then taken, and the concentration of the analyte in the sample is then calculated based on the value of the two polarization measurements.
Patent CA-2241406-A1 (CA)
Inventor: GOODCHILD MARTIN
IPC: B41J2/06
Filed: 1997-01-22
Abstract: The invention concerns an apparatus for generation and ejection into air of discrete agglomerations of a particulate material with a proportion of liquid from a liquid having the particulate material therein. The apparatus defines an ejection location (128) and an electrical potential is applied to the ejection location to form an electric field at the location, and liquid (122) with the particulate material is supplied to the ejection location. An oscillating voltage (A) is applied to the ejection location, the magnitude of the voltage being below that required to cause ejection of particles from the ejection location, and an ejection voltage (B) is superimposed on the oscillating voltage additively with the oscillating voltage in order to cause the sum of the voltages at the ejection location to exceed the threshold required for ejection, when required.

Filed: 1997-03-12
Abstract: Biofilm forming organisms are incubated to form a biofilm on projections by providing a flow of liquid growth medium across projections, the direction of the flow of liquid being repeatedly changed, and an assay made of the resulting biofilm. Biofilm forming organisms are incubated to form a biofilm on projections arranged in rows, with several projections in each row, while providing a flow of liquid growth medium across each row of projections, and an assay made of the resulting biofilm. Sensitivity of the biofilm to antimicrobial reagent may be determined by treating the projections with antimicrobial reagent before carrying out the assay, by treating each row of projections with a different antimicrobial reagent, and each of the projections in a row with a different concentration of antibacterial reagent. A biofilm assay device includes a vessel including at least one channel for flow of liquid growth medium, projections arranged in at least one row and having a support for supporting the projections within the channel, and a tilt table to flow liquid growth medium along each channel in different directions across the projections. A further biofilm assay device includes a vessel including channels for flow of liquid growth medium, projections arranged in rows and having a support for supporting the projections within the channels, and a rocking table to rock the vessel and flow liquid growth medium along each channel across the projections.

Abstract: A method and apparatus to prevent system deadlock in a dispatch system by monitoring link activity is described. The dispatch system is comprised of a set of remote units (10, 20, 22) which communicate with each other by broadcasting one at a time to the group. A  remote unit (10) communicates with the other remote units through at least one base station (44). A communications manager (40) grants a remote unit (10) to be the exclusive system talker upon request through the base station servicing the requesting remote unit (44). The base station (44) monitors a series of data from the remote unit designated as the system talker (10) to detect voice activity. The base station (44) sends a surrogate request to the communications manager (40) to relinquish the system talker privilege if the voice activity falls below a predetermined threshold.

Title: Method for characterising the coherence of an environment characteristic measurements
Inventor: RABILLER PHILIPPE
IPC: G01D21/00
Filed: 1998-06-11
Abstract: A method for evaluating the coherence of environmental measurements of a given geological medium or field using well logging data is disclosed. A  series of N geological parameters are each measured at a series of reference points found in reference wells within this medium. Each reference point is at a different depth and has known lithological characteristics, and the N measurements form a reference observation (X i) corresponding to that point. The same N parameters are measured at application points found in one or more application wells, at depths identical to those of the reference points, forming an application observation (x) for each application point. A neighbouring domain (D i) and acceptance class are defined for each reference observation (X i). Each application observation (x) is then compared with all of reference observations (X i) using a nearest-neighbour algorithm to determine the degree of membership of the application observation in each reference observation's acceptance class. This degree of membership is then used to predict or estimate the lithological characteristics for each application point.

The present invention particularly relates to an isolated p115 Rho-GEF polypeptide or fragments of it, a nucleic acid coding for p115 Rho-GEF or fragments of it, and derivatives of the polypeptide and nucleic acid. The invention also relates to methods of using such polypeptides, nucleic acids, or derivatives thereof, e.g., in therapeutics, diagnostics, and as research tools. Another aspect of the present invention involves antibodies and other ligands which recognize p115 Rho-GEF, regulators of p115 Rho-GEF activity, and methods of treating pathological conditions associated or related to a Rho GTPase.
