Patent number: 6917845Abstract: A method for controlling an industrial process. The method includes outputting a plurality of parameters from a process for manufacture of a substance. The method also uses each of the plurality of parameters in a computer aided process, which compares at least two of the plurality of parameters against a training set of parameters. The training set of parameters is generally predetermined. A step of determining if the at least two of the plurality of parameters are within a predetermined range of the training set of parameters also is included. Additionally, the method includes outputting a result based upon the determining step.Type: GrantFiled: March 9, 2001Date of Patent: July 12, 2005Assignee: Smiths Detection-Pasadena, Inc.Inventors: Chang-Meng B.

Patent number: 6895338Abstract: Methods and systems are provides for measuring multi-dimensional sensing information for identification purposes. The identity of one or more substances is determined through analysis of multidimensional data that can include, among others, intrinsic information as well as extrinsic information. The method for identification of a substance comprises utilizing pattern recognition to form descriptors to identify characteristics of the substance. A system and computer program for performing analysis of the multidimensional data are also described.Type: GrantFiled: March 9, 2001Date of Patent: May 17, 2005Assignee: Smiths Detection - Pasadena, Inc.Inventors: Chang-Meng B.

Publication number: 20030186461Abstract: The present invention is related to the sensing of analytes and in particular, to methods of determining, resolving, identifying, or quantitating such analytes once detected. This invention provides systems and methods for identifying analytes, comprising using an importance index to give greater weight to the responses from sensors that measure characteristics most useful for identification of analytes. In other aspects, the systems and methods are useful for increasing the stability of electronic nose systems by prolonging the predictive capability of the training set of known analytes. In still other aspects, the systems and methods are useful for detecting and responding to events correlated with the presence of an analyte.Type: ApplicationFiled: March 29, 2002Publication date: October 2, 2003Applicant: Cyrano Bioscienes, Inc.Inventors: Christopher K. Boehr, Shou-Hua Zhang, Chang-Meng Hsiung, Michael A. Vicic
