Title: Architecture layer interfacing devices and applications
Inventor: SCOGGINS SEAN MICHAEL
IPC: G06Q30/00
Filed: 1999-12-07
Abstract: An interface layer and method is provided that permits applications (10), without modification, to operate with any type of meter (30). The interface (20) comprises an abstraction layer and library or repository of descriptions specific to each meter type. The abstraction layer provides the capability to communicate with any meter (30) through a variety of applications (10). Upon receiving an application request, the abstraction layer retrieves the description for the particular meter type from the repository and processes the request. In this manner, only one data representation is needed for applications to communicate with a wide variety of meters (30).

Title: Dielectric breakdown chemical reactor for liquids
Inventor: PRUDKYY DMYTRO VASSILY
IPC: B01J19/00
Filed: 2000-02-15
Abstract: This invention relates to the enhancement of chemical reactions by applying a high frequency electric field to a material. The frequency and amplitude of the electric field are selected in accordance with properties of the reacting components in a bulk of chemical reactor. In general, the high frequency range is determined by the dielectric properties of reactant(s), that is, at any given temperature, when, for example, the specific conductivity starts to grow from its low frequency value. Typically, frequencies in the range of 100 kHz to 100 MHz or greater are suitable for the enhancement of the reactions.  An electric field having Fourier components that when applied to a chemical process exhibits growth in the real part of conductivity relative to the low frequency value is of particular importance.

Patent CA-2369579-A1 (CA)
Title: Controlled release of growth factors from heparin containing matrices
Inventor: HUBBELL JEFFREY A
IPC: A61K47/48
Filed: 1999-04-22
Abstract: Matrices that support cell adhesion and growth are disclosed that deliver low heparin-binding affinity growth factor protein peptides in a controlled manner. These matrices comprise covalently or non-covalently bound heparin or heparin-like polymers, which serve to sequester the low heparin-binding affinity growth factor protein peptides within the matrix. The controlled release of some low heparin-binding affinity growth factor or peptides thereof occurrs by degradation of some matrix component or dissociation of the low heparin-binding affinity growth factor protein peptides from the bound heparin. This differs from many controlled delivery devices in that release is not controlled solely by diffusion, and the rate of release may therefore be regulated by altering the rate of degradation of the matrix component or the amount of heparin bound within the matrix. The controlled release of such low heparin-binding affinity growth factor proteins such as NGF.beta., NT-3 and BDNF, is demonstrated. The invention also identifies basic domains that can be utilized to identify other low heparin-binding affinity growth factor protein peptides useful in delivery as part of the matrices described herein.

Title: A system and method for material processing using multiple laser beams
Inventor: MOFFAT STEVEN HAROLD
IPC: B23K26/06
Filed: 2000-04-26
Abstract: A material machining system for machining a workpiece (PCB, PWB etc.) for drilling blind vias. The system includes a laser supply system (20, 26, 30) for supplying discrete machining beams (22a, 22b) that are separate from each other. Deflecting devices (28, 32) are provided for deflecting each of the discrete machining beams to generate multiple independent beams at a plurality of positions within a field of operation on the workpiece. A scan lens (34) having an entrance pupil configured to receive the multiple independent beams from the deflecting devices is provided proximate to the entrance pupil of the scan lens. A computer is used for controlling the deflecting devices to change the respective positions of the multiple independent beams in at least one co-ordinate direction within the field of operation. The deflecting devices include galvo/mirror pairs at the entrance pupil of the scan lens. This is accomplished since the scan lens has a relatively large entrance pupil and the mirror parts are small. The advantage of this arrangement is the ability of all beams to access a full working field (typically 2x2 inches) on the workpiece simultaneously, so that the highest efficiency of laser power utilization is achieved.

Patent CA-2373326-A1 (CA)
Inventor: KASBAUM JANICE L
IPC: C01B32/50
Filed: 2000-05-12
Abstract: The present invention is a process to recover a high purity, high pressure hydrogen gas stream from synthesis gas. The synthesis gas is contacted with a membrane that separates the synthesis gas into a hydrogen-enriched permeate and a hydrogen-depleted non-permeate. The permeate is conveyed to a carbon dioxide absorber. The carbon dioxide absorber removes carbon dioxide using a  solvent. The carbon dioxide-rich solvent from the absorber is heated and sen t to a gas-liquid contactor, where the solvent is regenerated by nitrogen stripping. A small recycle stream of a regenerating gas, i.e., hydrogen, is subsequently contacted with the solvent, stripping entrained and dissolved nitrogen from the solvent. This stripping gas, the regenerating gas, or preferably both, are then mixed with the non-permeate for combustion in a combustion turbine.

Abstract: The invention provides a method and apparatus for providing hitless protection switching in a transmission systems which support a standardised implementation of virtual concatenation. A switching apparatus is arranged to receive data signals on at least two transmission paths and to output data from a selected one of said transmission paths. The apparatus is arranged to align the respective received data signals so that a selector mechanism can select between corresponding elements of the received data signals. This arrangement allows hitless switching to be performed since there is no loss or repetition of signal elements when switching occurs. In a preferred embodiment, data in respect of each frame of each data signal is stored and the selector mechanism selects between paths on a frame-by-frame basis by comparing quality information carried by the data signals.  This arrangement offers a very low end to end Bit Error  Rate (BER) performance.
