Title: System and method for hierarchical device extraction
Inventor: ROGOYSKI ERIC
IPC: G06F17/50
Filed: 1996-01-11
Abstract: A device extractor (120) for extracting devices from a hierarchical cell design (206). The device extractor (120) selects a cell from the lowest level of the hierarchy and searches the cell for the device components. The device extractor (120) searches each cell in the lowest level and then selects a "parent" cell in the penultimate level. The parent cell, and all of the children cells of the parent cell, are searched. The selection and search process continues until all of the components of the device (208) are identified in a cell or the children cell of the cell and a proper relationship between the components is determined. The components of the identified device (208) are masked so that they are not identified and associated with another device during subsequent searches.
Patent CA-2209623-A1 (CA)
Title: Speech coding method using synthesis analysis
Inventor: NAVARRO WILLIAM
IPC: G10L25/93
Filed: 1996-01-03
Abstract: A speech signal linear prediction analysis is performed for each frame of a speech signal to determine the coefficients of a short-term synthesis filter, and an open-loop analysis is performed to determine a degree of frame voicing. At least one closed-loop analysis is performed for each sub-frame to determine an excitation sequence which, when applied to the short-term synthesis filter, generates a synthetic signal representative of the speech signal. Each closedloop analysis uses the impulse response of a filter consisting of the shortterm synthesis filter and a perceptual weighting filter, by truncating said impulse response to a truncation length that is no greater than the number of samples per sub-frame, and dependent on the energy distribution of said response and the degree of voicing of the frame.

Title: Fluid line with integral conductor
Inventor: KORTE DAVID G
IPC: F16L7/02
Filed: 1998-01-08
Abstract: Conductors are placed in insulator which acts as a spacer/centralizer for the conductors, which are in turn mounted within tubing.

The conductors are protected because they are kept away from the tubing wall and can be further protected by the addition of the sealing material.
Patent CA-2228418-A1 (CA)
Inventor: GRAHAM ROBERT
IPC: C08H8/00
Filed: 1998-01-30
Abstract: This invention is directed to a method of preparing a natural resin by liquefying wood, bark, forest residues, wood industry residues, or other biomass using fast pyrolysis in order to produce product vapours and char. Following removal of the char from the product vapours, a first set of compounds are removed from the product vapours by rapid quenching in order to obtain a remaining selected product vapour from which a natural resin is obtained. The natural resin comprises a total phenolic content from about 30 % to about 80 % (w/w), and is further characterized as having a pleasant smoky odour. The natural resin has surprisingly been found to be suitable for use within adhesive formulations without requiring any further extraction or fractionation procedures. Adhesives comprising up to 60 % natural resin have been prepared and tested in board production and found to exhibit similar properties associated with commercially available resins. The natural resin may substitute for phenol. or for both phenol and formaldehyde within phenol-containing resins. Similarly, the natural resin can replace a substantial part of the components within urea-containing resins.

Patent CA-2228766-A1 (CA)
Title: Method of synchronization of receiver for digital signals
Inventor: BOLLE MICHAEL
IPC: H04L27/26
Filed: 1996-07-24
Abstract: A method and an arrangement for synchronizing a receiver for digital signals are described. The synchronizing information is derived from the center of distribution of the squared channel pulse response, which center of distribution is calculated directly from the sampling values of the channel frequency response. Thus a separate calculation of the channel pulse response via an inverse Fourier transform from the channel frequency response is unnecessary. The channel frequency response can be determined in a simple way by correlation of a received signal with a reference signal stored in memory in the receiver.

Inventor: BLOUIN JEAN
IPC: G06T11/00
Filed: 1998-07-28
Abstract: An image data modifying system has devices for image storage, display, processing and manual control. The storage device is arranged to store many modifying textures in the form of stamps having fewer pixels than a full image frame. The processing device constructs a new texture stamp by scaling a first stamping texture, expanding a second stamping texture without scaling and combining the scaled texture with the expanded texture. In this way, the effect of scaling artefacts is significantly reduced.

Title: Improved isolation system for vibratory equipment
Inventor: PATTERSON HAROLD E
IPC: F16F15/08
Filed: 1998-08-14
Abstract: An isolation component for vibratory equipment such as a vibratory trough or feeder includes an isolation spring for supporting the dynamic load of the equipment, and a damper element, preferably an elastomeric ring, arranged against an end of the isolation spring. The damper element prevents excessive motion of the isolation spring due to the vibratory equipment's operating frequency being close to any of the natural frequencies of the bending mode of the isolation spring by applying an opposing load to any such motion. The damper element is preferably an elastomer ring and is arranged along an axis of the support spring. A connector extends from a first end of the isolation spring, adjacent the damper element, toward and past a second end of the isolation spring and is connected to the vibratory equipment. The second end of the isolation spring is supported by a housing supported by external structure such that the weight and dynamic load of the equipment compresses and expands the isolation spring, and excessive expansion of the support spring acts on damper element which is braced against the housing.
