Publication number: 20250146188Abstract: Methods for fabricating coiled polymer fibers and yarns (high-spring-index coiled fibers and yarns). Methods include inserting twist separately into individual fibers or yarns, plying the fibers or yarns by inserting plying twist, setting the ply structure without permanently binding together the fibers or yarns of different plies so that the ply structure is substantially stable against untwist when torsionally untethered, and then unwrapping the plied fibers or yarns so that a high-spring-index fiber or yarn can be obtained. In some embodiments, the unwrapped fibers or yarns are further set so that these are further stabilized. The methods can eliminate the need for a mandrel, and can be quickly applied for applications where high-spring-index thermally-driven artificial muscles are presently employed, such as for presently commercialized comfort-adjusting jackets.Type: ApplicationFiled: January 9, 2025Publication date: May 8, 2025Applicant: BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEMInventors: Mengmeng ZHANG, Ray BAUGHMAN, Shaoli FANG, Jiyoung OH, Zhong WANG, Fatma GÖKTEPE, Özer GÖKTEPE

Patent number: 11966568Abstract: The method receives a visual specification, which specifies a data source, visual variables, and data fields from the data source. Each visual variable is associated with data fields and each data field is either a dimension or a measure. From an object model of the data source, the method identifies a minimal subtree that includes all of the dimension data fields and constructs a query from the minimal subtree. The method executes the query against the data source to retrieve a set of tuples, each tuple comprising a unique ordered combination of data values for the dimension data fields. For each tuple, the method forms an extended tuple by appending aggregated data values corresponding to each measure data field. The method then builds and displays a data visualization according to the data fields in the extended tuples and according to the visual variables to which the data fields are associated.Type: GrantFiled: December 30, 2018Date of Patent: April 23, 2024Assignee: Tableau Software, Inc.Inventors: Justin Talbot, Roger Hau, Daniel Cory, Jiyoung Oh, Teresa Roberts

Patent number: 11687571Abstract: Embodiments are directed to managing a data model that includes data objects associated with layers of the data model may be provided. A lineage model that includes lineage objects that has one or more lineage objects associated with a layer may be provided. A lineage object associated with a layer may be activated. A first portion data objects may be determined based on the activated lineage object. An anchor object may be determined from the first portion of data objects. A search of the data model may be employed to provide dependency information based on a position of the anchor data object in the data model. A second portion of data objects may be determined based on the dependency information. A report that includes a list of the second portion of data objects, the dependency information, or the like, may be provided.Type: GrantFiled: December 3, 2021Date of Patent: June 27, 2023Assignee: Tableau Software, LLCInventors: Tyler James-Buker Doyle, Graeme Riley Britz, Jonathan Joseph Bryak, Cassius David Butcher, Jun Ho Kim, Jiyoung Oh

Patent number: 11629705Abstract: Actuators (artificial muscles) comprising twist-spun nanofiber yarn or twist-inserted polymer fibers generate actuation when powered electrically, photonically, chemically, thermally, by absorption, or by other means. These artificial muscles utilize polymer fibers non-coiled or coiled yarns and can be either neat or comprising a guest. Devices comprising these artificial muscles are also described. In some embodiments, thermally-powered polymer fiber torsional actuator has a twisted, chain-oriented polymer fiber that has a first degree of twist at a first temperature and a second degree of twist at a second temperature in which the bias angles of the first degree and second degree of twist are substantially different.Type: GrantFiled: September 21, 2021Date of Patent: April 18, 2023Assignee: THE BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEMInventors: Na Li, Carter S.

Patent number: 11620315Abstract: The process receives a visual specification, which specifies data sources, visual variables, and data fields from the data sources. Each visual variable is associated with one or more data fields and each data field is either a dimension or a measure. For each measure m, the process identifies a set R(m) consisting of dimensions that are reachable from the measure by a sequence of many-to-one relationships in an object model for the data sources. For each distinct set R, the process forms a data field set S, consisting of each dimension in R and each measure m for which R(m)=R. For each set S and for each measure in the set S, the process aggregates values of the measure according to the dimensions in S. The process builds a data visualization according to the data fields in the set S and the visual variables they are associated with.Type: GrantFiled: March 2, 2018Date of Patent: April 4, 2023Assignee: TABLEAU SOFTWARE, INC.Inventors: Justin Talbot, Roger Hau, Daniel Cory, Jiyoung Oh, Teresa Roberts

Patent number: 11537276Abstract: The method receives a visual specification, which specifies a data source, visual variables, and data fields from the data source. Each visual variable is associated with data fields and each data field is a dimension or a measure. The method forms dimension tuples comprising distinct ordered combinations of data values for the dimensions D. For each measure, the method: forms a set S of the dimensions D plus dimensions from a primary key corresponding to the measure; retrieves intermediate tuples containing the fields in S and the measure, without aggregation; and aggregates the intermediate tuples according to the dimensions D. For each dimension tuple, the method forms an extended tuple by appending the aggregated data values corresponding to each measure field. The method then builds and displays a data visualization according to the extended tuples and the visual variables to which the data fields are associated.Type: GrantFiled: December 30, 2018Date of Patent: December 27, 2022Assignee: TABLEAU SOFTWARE, INC.Inventors: Justin Talbot, Roger Hau, Daniel Cory, Jiyoung Oh, Teresa Roberts
