Patent number: 10733166Abstract: A mesh engine can generate a nested icosahedral grid that maps data points of a plurality of data sets onto partitions on the nested icosahedral grid. The nested icosahedral grid can include an outer icosahedral grid with a first set of partition and an inner icosahedral grid with a second set of partitions. A first partition of the first set of partitions can be linked to the inner icosahedral grid.Type: GrantFiled: May 3, 2017Date of Patent: August 4, 2020Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventor: Patricia D. Pratt

Patent number: 10642898Abstract: A rendering engine can generate a three-dimensional (3D) graph. The 3D graph can include a plurality of partitions contiguously connected. Each partition corresponds to a respective data record in a data set and a surface of each partition corresponds to a given parameter that references a given data field in the respective data record. Visual indicia of the surface of each partition can vary as a function of a value for the given data field of the respective data record.Type: GrantFiled: April 11, 2017Date of Patent: May 5, 2020Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventor: Patricia D. Pratt

Patent number: 10444071Abstract: A calibration target for an image sensor can include a panel with a predetermined length and width. The calibration target can also include an optical fabric overlaying a surface of the panel that generates light on a predetermined spectral band corresponding to a spectral band detectable by the image sensor spaced apart from the calibration target by a predetermined distance. The generated light can have sufficient luminance to penetrate a predetermined depth of water and to saturate at least one pixel of the image sensor.Type: GrantFiled: August 31, 2016Date of Patent: October 15, 2019Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventor: Patricia D. Pratt

Patent number: 10412381Abstract: A calibration target for an image sensor can include a plurality of bulbs that each emit light at one or more predetermined wavelengths. The calibration target can also include a container circumscribing the plurality of bulbs. The plurality of bulbs can be stacked and scattered within a volume partially or fully enclosed by the container, and the container has an open top that defines an area for the calibration target. Additionally, the image sensor can be deployed on an aircraft or a satellite.Type: GrantFiled: November 22, 2016Date of Patent: September 10, 2019Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventor: Patricia D. Pratt

Patent number: 10393583Abstract: A calibration target for a hyperspectral image sensor can include a panel with a predetermined length and width. The calibration target can also include a dispersive fabric overlaying a surface of the panel that refracts and disperses light illuminated from an illumination source to provide light on a plurality of different spectral bands corresponding to spectral bands detectable by the hyperspectral image sensor.Type: GrantFiled: August 9, 2016Date of Patent: August 27, 2019Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventor: Patricia D. Pratt

Patent number: 10332288Abstract: A helical engine can convert a Cartesian data set that characterizes a Cartesian graph into a helical data set that characterizes a helical graph. The helical graph can include a helical shaped axis defining a given variable and deviations from the helical shaped axis that represent another variable.Type: GrantFiled: March 2, 2017Date of Patent: June 25, 2019Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventor: Patricia D. Pratt

Patent number: 10163236Abstract: Systems and methods are provided for analyzing large data sets. A source interface receives a data set representing at least two independent variables and at least one dependent variable. A modeling component defines a three-dimensional structure representing the data set and instantiates the structure as an object. The object is defined to have non-infinitesimal dimensions in all directions and defined material properties with at least one of a dimension of the object and a material property of the object being a function of the dependent variable. A structural engineering component manipulates the object to facilitate review of the data set represented by the object via one of a kinematic perturbation and application of a structural engineering tool to the object or directly applying mathematical methods to achieve similar results once the cognitive challenge is met by structurally organizing the data.Type: GrantFiled: February 28, 2017Date of Patent: December 25, 2018Assignee: Northrop Grumman Systems CorporationInventor: Patricia D. Pratt

Patent number: 10165264Abstract: A floating calibration target for an image sensor can include a plurality of hexagonally shaped floatation devices that each emit light at one or more predetermined wavelengths. The floating calibration target can also include a seine net circumscribing the plurality of hexagonally shaped floatation devices. The seine net draws the plurality of hexagonally shaped floatation devices toward each other to form a substantially contiguous surface for the floating calibration target.Type: GrantFiled: October 14, 2016Date of Patent: December 25, 2018Assignee: Northrop Grumman Systems CorporationInventor: Patricia D. Pratt

Patent number: 10136126Abstract: A seine net calibration target for an image sensor can include a given set of seine nets connected to form a polygon and another set of seine nets. Each seine net of the other set of seine nets is coupled to a vertex of the polygon at a given end and coupled to a respective one of a plurality of boats at another end. The seine net calibration target can also include a plurality of light sources arranged along a top edge of the given set of seine nets and the other set of seine nets. The plurality of light sources emits light at a predetermined wavelength.Type: GrantFiled: November 11, 2016Date of Patent: November 20, 2018Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventor: Patricia D. Pratt
