US Patent:

20080015726, Jan 17, 2008
Filed:

May 4, 2007
Appl. No.:

11/800461
Inventors:

Jerry Harvey - Plano TX, US
Alexander Schwarm - Austin TX, US
International Classification:

G06F 19/00
US Classification:

700110000, 700108000
Abstract:

A method and apparatus for diagnosing faults. A fault is detected. One or more process variables that contributed to the fault are determined. A relative contribution of each of the one or more process variables is determined. A determination is made as to which fault signatures match the fault, a match occurring when the relative contributions of the one or more process variables are within relative contribution ranges of the matching fault signature. Each fault signature is associated with at least one fault class.

20080015814, Jan 17, 2008
Filed:

May 4, 2007
Appl. No.:

11/800471
Inventors:

Jerry Harvey - Plano TX, US
Alexander Schwarm - Austin TX, US
International Classification:

G06F 11/30
G06F 17/18
US Classification:

702179000, 702183000
Abstract:

A method and apparatus for detecting faults. A set of data samples is received, the set of data samples including multiple process variables. One or more multivariate statistical models are adapted, wherein adapting includes applying a change to at least one univariate statistic of the one or more multivariate statistical models if the change is greater than a threshold value. The one or more multivariate statistical models are used to analyze subsequent process data to detect faults.

Filed:

Dec 19, 2007
Appl. No.:

12/004667
Inventors:

Jerry Lynn Harvey - Plano TX, US
Alexander T. Schwarm - Austin TX, US
International Classification:

G06F 19/00
US Classification:

700110
Abstract:

Process data is analyzed, the process data having been generated during a manufacturing process to detect a fault. One or more process variables of the manufacturing process that contributed to the fault are determined. A relative contribution of each of the one or more process variables to the fault is determined. A fault signature having relative contribution ranges for at least one of the one or more process variables is generated, the relative contribution ranges based on the determined relative contributions.
