Patent number: 9136689Abstract: Embodiments of the present invention provide an approach for monitoring electrical disturbance (e.g., surges, outages, etc.) possibilities, and then automatically isolating electronic devices (also referred to herein as electronics) for the duration of the disturbance (or threat thereof). In a typical embodiment, a probability of an electrical disturbance occurring at a specified location will be determined. Then, a set of device protection profiles will be accessed. The set of device protection profiles comprises a set of thresholds and a corresponding set of device topologies associated with a set of electronic devices positioned. The set of thresholds in the set of device protection profiles will then be compared to the probability to identify a matching device topology from the set of device topologies. According to the matching device topology, at least one electronic device will be isolated from an electrical power source.Type: GrantFiled: October 19, 2011Date of Patent: September 15, 2015Assignee: International Business Machines CorporationInventors: Jason L. Anderson, Gregory J. Boss, Andrew R. Jones, Kevin C. McConnell, John E. Moore, Jr.

Patent number: 9110554Abstract: A method, computer program product, and system for a quality-of-service history database is described. A first input associated with a change to a component of a graphical user interface is received, wherein a portion of the component is represented as a first node of a tree structure representing a portion of the graphical user interface. A first characteristic of the change is determined. The first characteristic of the change is associated with a second node of the topic tree structure. The associated first characteristic is transmitted to a first computing device, wherein transmission of the associated first characteristic allows one or more of the first computing device and a second computing device to determine a first aspect of the change based upon, at least in part, the topic tree structure.Type: GrantFiled: June 14, 2013Date of Patent: August 18, 2015Assignee: International Business Machines CorporationInventors: Steven J. Horsman, Matthew J. Kockott, Jonathan C. Mace, Andrew Moger

Patent number: 9069352Abstract: A process for determining a root cause problem for an out-of-tolerance component manufactured by a plurality of operations performed on the component. The process can include providing manufacturing data from at least a subset of plurality of operations performed on a plurality of components and discovering an out-of-tolerance measurement on at least a subset of the plurality of manufactured components downstream from the plurality of operations. An auto-regression analysis between the out-of-tolerance measurement and the plurality of upstream operations can also be performed using the manufacturing data. A correlation between at least one of the upstream operations and the out-of-tolerance measurement can be found and the correlation can result in the identification of at least one upstream operation that is the root cause of the out-of-tolerance measurement.Type: GrantFiled: December 19, 2011Date of Patent: June 30, 2015Assignee: JDT Processwork Inc.Inventor: Jeffrey Trumble

Patent number: 9064788Abstract: A statistical process control method for monitoring and controlling semiconductor manufacturing processing operations is provided. For a chosen processing operation, multiple measurement sites are used to generate data of a measurable characteristic that is impacted by and associated with the processing operation. The data from the sites is compared over time and one or more outlier sites are identified. The outlier sites are the sites at which the data values are most divergent from the rest of the data. Algorithms are used to mathematically compare the outlier sites to the other sites to produce a comparative index. The comparative index is monitored graphically or otherwise to identify changes in the processing operation, and corrective actions are taken.Type: GrantFiled: February 19, 2014Date of Patent: June 23, 2015Assignee: WAFERTECH, LLCInventors: Liwen Lu, Shih-Tzung Chang
