Patent CA-2393449-A1 (CA)
Title: Transformation method applied to seismic data traces
Inventor: FULLER BRIAN N
IPC: G01V1/28
Filed: 2000-12-06
Abstract: A method for processing of seismic data traces utilizes the fact that a series of linear operations (40) applied to vectors (10) can be approximated by application of the linear operations to a set of basis vectors (20) which are then scaled and summed (40). The method is applied to seismic data traces (5) with a reduction in processing time provided that computation time in creating the basis vectors is small relative to the total computation time in applying the method. Theoretically there is much to be gained in terms of processing speed by implementation of this method on a vector processor (50) that is designed to multiply and accumulate operations quickly.

Abstract: An air diffuser (2) comprises a diffuser tube (5) immersed sidewardly in a tank (1), a flushing pipe (9) opening at its tip an outlet (11) at an upper position of the diffuser tube, and a flushing valve (12) disposed in the flushing pipe (9). The diffuser tube (5) is made up of a main pipe (6) communicated at its basal end to an air supply source (8) and communicated at its tip to the flushing pipe (9), and a plurality of branch pipes (7) being communicated to the main pipe (6) and opening at their tip as a blowhole (10) at a lower position of the main pipe (6). During air diffusion, air is supplied from the air supply source (8) with the flushing valve (12) closed, and the air is diffused from the blowholes (10). During flushing, air is supplied from the air supply source (8) with the flushing valve (12) opened and an intra-tank mixed liquor is sucked from the openings of the diffuser tube (5), thereby flushing the inside of the diffuser tube (5) with the sucked intra-tank mixed liquor. The intra-tank mixed liquor is then joined with air to come off together from the outlet (11) of the flushing pipe (9). Air diffusion from the blowholes (10) and the flushing of the diffuser tube (5) are alternately repeated by utilizing pulsation to be caused by pressure variations in the diffuser tube (5).

Patent CA-2412449-A1 (CA)
Inventor: HARDWICK JOHN C
IPC: G10L25/90
Filed: 2002-11-20
Abstract: An improved speech model and methods for estimating the model parameters, synthesizing speech from the parameters, and quantizing the parameters are disclosed. The improved speech model allows a time and frequency dependent mixture of quasi-periodic, noise-like, and pulse-like signals. For pulsed parameter estimation, an error criterion with reduced sensitivity to time shifts is used to reduce computation and improve performance. Pulsed parameter estimation performance is further improved using the estimated voiced strength parameter to reduce the weighting of frequency bands which are strongly voiced when estimating the pulsed parameters. The voiced, unvoiced, and pulsed strength parameters are quantized using a weighted vector quantization method using a novel error criterion for obtaining high quality quantization. The fundamental frequency and pulse position parameters are efficiently quantized based on the quantized strength parameters.  These methods are useful for high quality speech coding and reproduction at various bit rates for applications such as satellite voice communication.

Title: Accessibility correction factors for electronic models of cytochrome p450 metabolism
Inventor: TIEU HUNG
IPC: G16B15/30
Filed: 2001-07-09
Abstract: Accessibility correction factors may be used to modify values predicted by models of electronic component substrate reactivity. Most of the correction factors described herein pertain to either steric or orientation effects on substrate accessibility. The correction factors may be derived from one or more "descriptors" of the substrate structure. Each group of descriptors and associated correction factor pertain to a particular site on the substrate. Examples of such descriptors include site polarity, protrusion, partial surface area, partial charge, etc. Often the correction factor is a function of multiple descriptors. The function may be an expression comprising multiple terms, each representing the weighted contribution of a particular descriptor. In other embodiments, the correction factor is simply a descriptor or a descriptor multiplied by a coefficient or other function.

Abstract: An improved method and apparatus is provided as a system to enhance skin appearance and health, in which skin is cleaned (or exfoliated) and conditioned by use of microelements affixed to a base element or hand-held patch. The dimensions of the microelements are controlled so as to remove a certain number of layers of skin cells and to accumulate those skin cells, along with other foreign substances, into areas between the microelements. In addition, a conditioning compound or therapeutic active can be applied to the exfoliated skin to enhance the skin. Moreover, the amount of accumulated skin cells represents a self-limiting maximum quantity that cannot be substantially exceeded regardless of the number of attempts by a user to re-use the microstructure apparatus.

Patent CA-2444208-A1 (CA)
Inventor: YI YEN-LING
IPC: A61K31/407
Filed: 2003-10-02
Abstract: The present invention provides pharmaceutically acceptable salts having local anesthetic and anti-inflammatory activities. The preferred pharmaceutically acceptable salt is a diclofenac salt of lidocaine. Diclofenac is a non-steroidal anti- inflammatory drug ("NSAID"). Lidocaine is a local anesthetic. Other NSAID (excluding the salicylic acid derivatives) can be used to replace diclofenac and/or other local anesthetics can be used to replace lidocaine. The pharmaceutically acceptable salts are crystalline compounds, which are distinctively different from either the NSAID alone or the local anesthetic alone, as indicated by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), High Performance Liquid Chromatography (HPLC) and Fourier-Transformed Infrared Spectroscopy (FTIR) analyses. These pharmaceutically acceptable salts are suitable for use in topical treatment or parenteral injection to treat patients with localized pain, including muscle pain, joint pain, pain associated with herpes infection, and wound pain (such as surgical wound, burn wound etc.).

Patent CA-2444881-A1 (CA)
Inventor: MCGRATH ROGER W
IPC: H04L12/56
Filed: 2002-04-26
Abstract: The invention is a system and method to allow precise control of the transmit packet rate between two different networks (120) and to optionally introduce a priority servicing scheme across several related output ports of a switch engine (110). The invention employs flow control circuitry (101) to regulate data packet flow across a local interface (100) within a single device by asserting back-pressure. Specifically, flow control is used to prevent a switch port (102) from transmitting a data packet until a subsequent processing stage is ready to accept a packet via that port (102). The downstream node only permits transmission of packets from the switch when its buffer is available.
