Patent CA-2417358-A1 (CA)
Inventor: SANTI DANIEL V
IPC: C12P17/18
Filed: 2001-08-09
Abstract: The present invention relates to compounds made by a subset of modules from one or more polyketide synthase ("PKS") genes that are used as starting material in the chemical synthesis of novel molecules, particularly naturally occurring polyketides or derivatives thereof. The biologically derived intermediates ("bio-intermediates") generally represent particularly difficult compounds to synthesize using traditional chemical approaches due to one or more stereocenters. In one aspect of the invention, an intermediate in the synthesis of epothilone is provided that feeds into the synthetic protocol of Danishefsky and co-workers. In another aspect of the invention, intermediates in the synthesis of discodermolide are provided that feed into the synthetic protocol of Smith and co-workers. By taking advantage of the inherent stereochemical specifity of biological processes, the syntheses of key intermediates and thus the overall syntheses of compounds like epothilone and discodermolide are greatly simplified.

Abstract: A composite board is made from waste medium density fiber (MDF) board or waste particle board that includes solid urea formaldehyde. The waste board is chopped and milled into particles having a size between 20 mesh and 150 mesh, creating a waste flour. After removing moisture from the waste flour, the dried waste flour is mixed with a thermoplastic to bind and encapsulate the waste flour. Internal lubricants are added to improve the flow characteristics of the blended material, and external lubricants are added to present sticking of the mixture to an extruder or mold. Mineral fillers are added to improve the flexural modules of the composite board, and a plasticizer can be added to improve the physical properties or mechanical characteristics of the mixture. An ultraviolet absorber, a biocide, and a pigment can also be added. The blended material is extruded or molded into a desired shape. When cooled, the thermoplastic hardens to form a solid composite board.

Inventor: RICK ROLAND
IPC: H04B7/06
Filed: 2002-01-11
Abstract: In an antenna diverstiy environment, the timing offset of the receiver's fingers are based on the timing offset of the received peaks of the base station transmit signals. In a system with non-neglible multipath spacing, t he timing offset of the received peaks of the base station transmit signals are  not necessarily at the same location. In one embodiment, the demodulating elements for the signal from each base station antenna use the same offset f or demodulating and determining an error signal based on pilot signal sampling prior to the timing offset and subsequent to the timing offset. The error signals are averaged and used by a time trackin loop to track the incoming signal. In another embodiment, the demodulating elements for the signal from  each base station antenna independently time track the signals with differen t times offsets for each finger. The preferred embodiment depends on the metho d used by the base station to multiplex the data onto multiple transmit antenn as.

Title: Method and apparatus for stabilization of angiography images and a networked system for storage and playback of angiography images
Inventor: ROBERT NORMAND
IPC: H04N5/32
Filed: 2001-02-09
Abstract: A method for stabilizing and optimizing angiogram cine runs. The method for stabilizing involves reducing abrupt motion from the last frame to the first frame by refining the choice of the estimates of first and last frame indices provided by the user and by performing image registration so that a feature of interest is nearly in the same position between the last and first frame.  According to another aspect, a network accessible system for storing and playing back angiographic images and presenting patient information is provided. The most diagnostically relevant subset of frames are extracted from selected cine runs and made available over a wide area network (WAN) such as the Internet. The process of identifying a subset of frames encompassing a few cardiac cycles from the most relevant cine runs makes it possible for authorized users to view the images on a web page interface from remote locations like homes or offices using the Internet which otherwise suffers from bandwidth limitations that restricts the amount of data that can be transmitted within a reasonable delay.

IPC: H02J7/02
Filed: 2002-05-21
Abstract: A circuit (M) to monitor and protect individual cells (12-1 12-n) of a multi-cell battery (10) from over-charge and acquire data to be used to determine various characteristics of the cell state-of-health is connected to each individual cell (12) of a multi-cell battery as the battery is being charged.  The circuit includes a portion (Q1-R5) to bypass charging current from the cell, this portion being variably pre-settable to bypass current above a desired high voltage (V-By) limit for the cell. As the battery is being charged, the bypass circuit will shunt current around a cell when he preset high voltage level is exceeded, thus preventing any damage to the cell. The circuit (Q2) can be operated to produce a pulse of current and the change in voltage of the monitored cell in response to the change in current, dV/dl, can be used to determine the cell internal resistance. The cell polarization resistance also can be determined. The data acquired can be used to determine factors relating to the cell state of charge (SOC) and its state of health. A  programmable controller (C) controls all of the circuits and also acquires the data produced by the circuits.
