Patent number: 9519677Abstract: Data graphing methods, articles of manufacture, and computing devices are described. In one aspect, a method includes accessing a data set, displaying a graphical representation including data of the data set which is arranged according to a first of different hierarchical levels, wherein the first hierarchical level represents the data at a first of a plurality of different resolutions which respectively correspond to respective ones of the hierarchical levels, selecting a portion of the graphical representation wherein the data of the portion is arranged according to the first hierarchical level at the first resolution, modifying the graphical representation by arranging the data of the portion according to a second of the hierarchal levels at a second of the resolutions, and after the modifying, displaying the graphical representation wherein the data of the portion is arranged according to the second hierarchal level at the second resolution.Type: GrantFiled: October 7, 2011Date of Patent: December 13, 2016Assignee: Battelle Memorial InstituteInventors: Pak Chung Wong, Patrick S. Mackey, Kristin A. Cook, Harlan P. Foote, Lynn-Marie Peashka, Mark A. Whiting

Patent number: 8553034Abstract: One embodiment of the present invention includes a data communication subsystem to receive a data stream, and a data processing subsystem responsive to the data communication subsystem to generate a visualization output based on a group of data vectors corresponding to a first portion of the data stream. The processing subsystem is further responsive to a change in rate of receipt of the data to modify the visualization output with one or more other data vectors corresponding to a second portion of the data stream as a function of eigenspace defined with the group of data vectors. The system further includes a display device responsive to the visualization output to provide a corresponding visualization.Type: GrantFiled: May 7, 2009Date of Patent: October 8, 2013Assignee: Battelle Memorial InstituteInventors: Pak Chung Wong, Harlan P.

Patent number: 8126804Abstract: Methods and systems for automated decision support in analyzing operation data from a complex network. Embodiments of the present invention utilize these algorithms and techniques not only to characterize the past and present condition of a complex network, but also to predict future conditions to help operators anticipate deteriorating and/or problem situations. In particular, embodiments of the present invention characterize network conditions from operation data using a state estimator. Contingency scenarios can then be generated based on those network conditions. For at least a portion of all of the contingency scenarios, risk indices are determined that describe the potential impact of each of those scenarios. Contingency scenarios with risk indices are presented visually as graphical representations in the context of a visual representation of the complex network.Type: GrantFiled: March 23, 2009Date of Patent: February 28, 2012Assignee: Battelle Memorial InstituteInventors: Zhenyu Huang, Pak Chung Wong, Jian Ma, Patrick S Mackey, Yousu Chen, Kevin P Schneider

Patent number: 8073859Abstract: One or more processors (22) are operated to extract a number of different event identifiers therefrom. These processors (22) are further operable to determine a number a display locations each representative of one of the different identifiers and a corresponding time. The display locations are grouped into sets each corresponding to a different one of several event sequences (330a, 330b, 330c. 330d, 330e). An output is generated corresponding to a visualization (320) of the event sequences (330a, 330b, 330c, 330d, 330e).Type: GrantFiled: May 6, 2009Date of Patent: December 6, 2011Assignee: Battelle Memorial InstituteInventors: Pak Chung Wong, Elizabeth R. Jurrus, Wendy E. Cowley, Harlan P. Foote, James J. Thomas
