Patent CA-2309194-A1 (CA)
Inventor: POMFRET STEPHEN JOHN
IPC: H01B13/00
Filed: 1998-10-30
Abstract: A fluid conductive polymer mixture for use in the preparation of coatings, films and fibres is based on a polyaniline in base form (preferably emeraldine-base form). This is doped with a sulfonic acid having in addition to at least one sulfonic acid group a second hydrogen-bonding functional group and is dispersed in an acid solvent having a pKa less than 4.5 but substantially higher (more positive) than that of the sulfonic acid. The functional sulfonic acid appears to act as a solvating agent, as well as dopant, and allows the formation of high-solids mixtures in the acid solvents (up to around 15 % w/v compared with a maximum of about 10 % in conventional NMP-based mixtures) from which solvent can be extracted with a competing solvent (e.g. in a wet-spinning process); cold- (and hot-) drawable films and fibres can be obtained.  Preferred sulfonic acid is 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPSA) or its oligomer and preferred acid solvent dichloroacetic acid. The competing solvent may be acetone, methyl isobutyl ketone or butyl acetate.

Title: Pricing module for financial advisory system
Inventor: JONES CHRISTOPHER L
IPC: G06Q40/00
Filed: 1998-09-22
Abstract: The pricing module of the present invention provides a single module that models both fixed-income securities and equity securities into the future in an arbitrage-free model. Because the modeling includes both fixed-income securities and equity securities that are modeled based on common input state variables and does not allow arbitrage conditions between the fixed-income securities and the equity securities (as well as no arbitrage within a security class), the present invention provides an improved pricing module as compared to those in the prior art.

Abstract: A silica-based core rod is traversed by a heat source along its longitudinal axis, to provide heated, softened regions. During the traverse, compressive or tensile movements are provided along the rod's longitudinal axis, these movements inducing, respectively, increases or decreases in the core diameter at the softened regions.      By providing selective core diameter increases and/or decreases across the entire length of the core rod, a desired core diameter profile is attained. It is possible to attain a substantially uniform core diameter, or a varying core diameter profile that provides particular properties, such as systematically varying dispersion. In addition, due to the ability to increase core diameter and core rod diameter in a controlled manner, it is possible to make larger core rods, and in turn larger fiber preforms, than presently possible.

Abstract: A method and a system for measuring the energy of a signal are described herein. The method is based on the use of a time-frequency distribution using as kernel a bi-directional filter having compact support properties. The two-dimensional filter is applied to the two-dimensional correlation function of the signal to be analysed. The method allows a better reduction of false energy observances (interference) while providing good resolution in time and in frequency.
