Systems and methods for visualizing multi-dimensional data in spreadsheets and other data structures
Patent number: 6707454Abstract: The data visualization systems and methods of this invention provide a powerful tool for visualizing multi-dimensional databases. In one exemplary embodiment, the data visualization systems and methods of this invention visualize pivot tables using two novel visual metaphors: a single measure perspective consisting of linked bar charts and a multiscape landscape visualization; and a anchored measures perspective for displaying several measures simultaneously. The data visualization systems and methods of this invention usefully display much larger pivot tables than is possible using conventional interfaces and provide the ability to navigate through complex cubes to identify important structures. In various exemplary embodiments, the data visualization systems and methods of this invention attach to MS Excel™ as an add-on, access pivot tables directly from SQL Server 7.0, and integrate with MS Office.Type: GrantFiled: October 12, 1999Date of Patent: March 16, 2004Assignee: Lucent Technologies Inc.Inventors: Timothy A. Barg, Susan K. Burkwald, Stephen G. Eick, Brenda A. Garity, Dianne K. Hackborn, Barbara R. Mirel, William C. Swanson, Michael S. Tatelman -
Publication number: 20020070953Abstract: A tree-structured workflow control and a tree-structured report selection control allow users to easily display data and generate reports, without having to actively determine the various measures and dimensions to be displayed in various interactive views of the data and various simple and advanced reports. By linking predetermined sets of dimensions, measures and views to predetermined workflow control entries and report selection entries in a tree structure having labels on the branches and leaves that are logically related to the associated predetermined sets, the user can immediately obtain a data visualization perspective or a report without having to actively select the particular dimensions and measures for display, and without having to actively arrange the selected dimensions into a multi-dimensional view.Type: ApplicationFiled: May 4, 2001Publication date: June 13, 2002Inventors: Timothy A. Barg, Stephen G. Eick, Jonathan C. Martin, William C. Swanson, Ronald D. Smith, Darryl Whitmore, Kurt D. Rivard

Patent number: 4141283Abstract: An unloading valve spool with a tapered nose section is urged across a pair of unloading ports at a controlled rate eliminating violent upstream pressure generation. The unloading valve is subjected to equal system fluid pressure on each side of it as the spool is provided with a through passage that is dead headed on the back side of the unloading spool. A return spring urges the unloading spool to a normally closed position. An unloading piston prevents the unloading spool from closing too rapidly preventing the generation of a significant upstream pressure spike.Type: GrantFiled: August 1, 1977Date of Patent: February 27, 1979Assignee: International Harvester CompanyInventors: William C.

Patent number: 4061079Abstract: A fluid operated motor amplifies input force and communicates a greater amount of output force to a reaction device. Input effort is directly proportional to the amplified output effort. A power piston residing in a cylinder bore has an input rod, having a spool valve and a reaction piston, laterally movable through a bore in the power piston. Fluid flow is metered to a working chamber by the spool valve in response to the position of the input rod. An output rod moves with the power piston to deliver an amplified force to a linkage.Type: GrantFiled: May 4, 1976Date of Patent: December 6, 1977Assignee: International Harvester CompanyInventors: Harold R.
