In this method each array region may be exposed to a corresponding continuous volume of a sample fluid. A method and apparatus are also provided for reading arrays disposed along a surface of a flexible elongated web. In one such method the web with the arrays thereon may be transported in a lengthwise direction past a reading location at which a characteristic of the features is read, while restraining the web on both surfaces on either side of the reading location to assist in maintaining the reading location flat.Type: GrantFiled: October 18, 2001Date of Patent: November 27, 2007Assignee: Agilent Technologies, Inc.Inventors: Michel G. M. Perbost, Steven M. Lefkowitz, Roy H. Kanemoto, Carol T. Schembri

Patent number: 7297549Abstract: A method of determining bias in a measurement of a constituent concentration level in a sample gas is provided. The method comprises establishing a sample gas flow from an emission stream into a sample gas line of an emissions monitoring system. The method further comprises removing water from the sample gas flow and cooling the sample gas flow to a temperature below about 41° F. to produce a cooled, dried sample gas flow. The constituent concentration level is then determined for the cooled, dried sample gas flow. The method further comprises introducing a span gas having a known span gas constituent concentration level into the sample gas flow to form a combined sample and span gas flow, the span gas being introduced at a desired span gas flow rate. The method still further comprises removing water from the combined sample and span gas and cooling the combined sample and span gas to a temperature below about 41° F. to produce a cooled, dried, combined sample and span gas flow.Type: GrantFiled: March 6, 2002Date of Patent: November 20, 2007Assignee: General Electric CompanyInventors: William Steven Lanier, Glenn England

Patent number: 7291311Abstract: Process for controlling the combustion zone of a fluidized bed process comprising a regeneration zone and a reaction zone, the catalyst circulating between these two zones, and the regeneration zone comprising a combustion stage of the coke deposited on the catalyst in the reaction zone, control of the combustion zone being performed on the basis of a characteristic variable of the operation of said combustion zone, said characteristic variable being the object of automatic regulation by acting on the catalyst throughput, characterized in that the value of the catalyst throughput or of any control variable connected unequivocally to the catalyst is determined based on information on the operating values of the combustion zone, at least one of which corresponds to an independent evaluation of the level of coke deposited on the catalyst.Type: GrantFiled: August 14, 2003Date of Patent: November 6, 2007Assignee: Institut Francais du PetroleInventor: Eric Sanchez

Patent number: 7288229Abstract: An apparatus and method for carrying out and monitoring the progress and properties of multiple reactions is disclosed. The method and apparatus are especially useful for synthesizing, screening, and characterizing combinatorial libraries, but also offer significant advantages over conventional experimental reactors as well. The apparatus generally includes multiple vessels for containing reaction mixtures, and systems for controlling the stirring rate and temperature of individual reaction mixtures or groups of reaction mixtures. In addition, the apparatus may include provisions for independently controlling pressure in each vessel, and a system for injecting liquids into the vessels at a pressure different than ambient pressure. In situ monitoring of individual reaction mixtures provides feedback for process controllers, and also provides data for determining reaction rates, product yields, and various properties of the reaction products, including viscosity and molecular weight.Type: GrantFiled: May 8, 2001Date of Patent: October 30, 2007Assignee: Symyx Technologies, Inc.Inventors: Howard Turner, G. Cameron Dales, Lynn VanErden, Johannes A. M. van Beek

Patent number: 7286942Abstract: A system and method of fluctuation enhanced gas-sensing using SAW devices includes processes for improved chemical analyte detection, identification, and quantification through the measurement and spectral analysis of frequency fluctuations in the instantaneous frequency of a chemical sensor arranged to produce an oscillatory output signal when exposed to chemical substances. The system and method may use a chemical sensor, such as a surface acoustic wave (SAW) device. The spectral analysis produces the power spectral density of the frequency fluctuations, which are represented as a pattern that includes information about the analyte(s) such as, total adsorbed gas mass and diffusion coefficients. The diffusion coefficients may then be used to determine the number of molecule types and/or the concentration of each.Type: GrantFiled: October 2, 2003Date of Patent: October 23, 2007Assignee: United States of America as Represented By The Secretary of the NavyInventors: Laszlo B.

Patent number: 7276380Abstract: The present invention provides a transparent liquid inspection apparatus capable of identifying a boundary between a transparent liquid applied on a base material which provides a multi-piece product and the base material, and automatically inspecting an applied condition of the transparent liquid without influence of a background of the base material. A projected image of an illumination source (2) is reflected on a surface of the transparent liquid as a mirror, the projected image is picked up by cameras (41 to 44), and the image is analyzed by an image processing unit (8), thereby inspecting an amount of displacement of the transparent liquid from a predetermined application position and expansion of the surface of the transparent liquid.Type: GrantFiled: July 30, 2001Date of Patent: October 2, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Teruaki Fukuyama
