Patent number: 11866901Abstract: Aspects of a geogrid system and method for improving substrate interactions within a geotechnical environment is disclosed. In one aspect a geotechnical environment is configured with a horizontal multilayer mechanically stabilizing geogrid. In said aspect the geogrid is extruded with a polymeric material and a compressible cellular layer, wherein the geogrid comprises a heightened aspect ratio with a patterned structure of engineered discontinuities and a plurality of strong axes. The combination of elements provides for a system and method of stabilizing soils and aggregate, by resisting lateral movement from the strong axes, and trapping particles in the patterned structure of engineered discontinuities.Type: GrantFiled: December 6, 2022Date of Patent: January 9, 2024Assignee: Tensar International CorporationInventors: Andrew Curson, Tom Ross Jenkins, Andrew Edward Waller, Daniel John Gallagher, Daniel Mark Baker, Manoj Kumar Tyagi, Joseph Cavanaugh

Publication number: 20230364932Abstract: A technique is described for the application of three-dimensional (3D) relief to a substrate such as a ceramic tile using digital inkjet technology. A computer system receives information defining a relief pattern for forming the 3D relief using a digital inkjet printer. From the information, a feature vector is extracted comprising one or more features describing the 3D relief. A machine learning model is used to generate control commands based on the feature vector. The machine learning model is trained to generate the control commands to configure the digital inkjet printer to apply binder ink to a first region of a surface of the substrate. The applied binder ink is configured to form a protective layer over the first region of the surface of the substrate. The digital inkjet printer is configured to apply solvent ink to the surface of the substrate.Type: ApplicationFiled: July 27, 2023Publication date: November 16, 2023Inventors: Mark ZAVADA, Matthew TENNIS, David WEBER, Alexander MERANTO, Carlos CARRATALÁ, Fernando Tomás BADENES, Louis Justus FAGE, Ursula GOOD, Paul Andrew EDWARDS, Robert ROGGERS, John HANSEN

Publication number: 20230358643Abstract: Highly efficient and rapid filtration-based concentration devices, systems and methods are disclosed with sample fluidic lines and a filter packaged in a disposable tip which concentrate biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream. The concentrate is then dispensed from the disposable tip in a set volume of elution fluid. Suspended biological particles include such materials as proteins/toxins, viruses, DNA, and/or bacteria in the size range of approximately 0.001 micron to 20 microns diameter. Concentration of these particles is advantageous for detection of target particles in a dilute suspension, because concentrating them into a small volume makes them easier to detect. A single-use pipette tip includes fluid ports for aspirating the sample and connecting to a concentrating unit.Type: ApplicationFiled: July 16, 2023Publication date: November 9, 2023Inventors: Andrew Edward Page, Zachary A.

Publication number: 20230325159Abstract: Compilation is supported and improved by varying the order of invocation of register allocation heuristics during code generation. A particular invocation order may be chosen based on one or more compilation scenario properties, such as a target processor architecture, a target operating system, a kind of source code being compiled, or optimization targets for the compiler or the generated code, or a mix thereof. Suitable heuristics invocation orders may be produced efficiently and effectively using a genetic algorithm that is adapted to make a population of invocation orders, select parents, create offspring, and assess invocation order fitness, until the population converges on optimal orders. Invocation order fitness assessments may be based on actual performance or simulated performance.Type: ApplicationFiled: April 11, 2022Publication date: October 12, 2023Inventors: Kunal PATHAK, Andrew Edward AYERS

Publication number: 20230304906Abstract: Devices, systems and methods are disclosed which relate to using a wet foam elution method for removal of particles from a flat filter. Particles are captured from the atmosphere onto the flat filter. The flat filter is then placed into an extractor which passes a stream of wet foam through the flat filter. Expansion of the foam works to efficiently remove captured particles. The foam flows from the filter along with the captured particles into a sample container. Once in the sample container, the foam quickly breaks down leaving an analysis ready liquid sample.Type: ApplicationFiled: June 2, 2023Publication date: September 28, 2023Inventors: Andrew Edward Page, David Scott Alburty, Alec D.

Multilayer integral geogrids having a cellular layer structure, and methods of making and using same
Patent number: 11753788Abstract: A multilayer integral geogrid, including one or more cellular layers, has a plurality of oriented multilayer strands interconnected by partially oriented multilayer junctions with an array of openings therein. The multilayer integral geogrid having one or more cellular layers is produced from a coextruded or laminated multilayer polymer starting sheet. The integral geogrid has a multilayer construction, with at least one outer layer thereof having the cellular structure. By virtue of the cellular layer structure, the multilayer integral geogrid provides for increased layer vertical compressibility under load, resulting in enhanced material properties that provide performance benefits to use of the multilayer integral geogrid to stabilize and strengthen soil, aggregates, or other particulate materials.Type: GrantFiled: December 21, 2021Date of Patent: September 12, 2023Assignee: TENSAR INTERNATIONAL CORPORATIONInventors: Joseph Cavanaugh, Manoj Kumar Tyagi, Daniel Mark Baker, Andrew Curson, Tom-Ross Jenkins, Andrew Edward Waller, Daniel John Gallagher -
Publication number: 20230278277Abstract: A monolayer multi-axial integral geogrid suitable for stabilizing aggregate includes a plurality of interconnected oriented strands and partially oriented junctions forming a repeating pattern of outer hexagons having an array of openings therein. Oriented ribs extending inwardly from each of said outer hexagons support and surround a smaller inner hexagon having oriented strands thus forming a plurality of trapezoidal openings and a single hexagonal opening. The oriented strands and partially oriented junctions of the outer hexagons form a plurality of linear strong axis strands that extend continuously throughout the entirety of the geogrid and form additional triangular openings. The geogrid thus includes three different repeating geometric shapes. The inner hexagons preferably also can move up and down, out of the plane of the geogrid. The multi-axial integral geogrid thus provides a geometry that can better engage with, confine and stabilize a greater variety and quality of aggregates.Type: ApplicationFiled: December 5, 2022Publication date: September 7, 2023Applicant: Tensar International CorporationInventors: Andrew CURSON, Tom-Ross JENKINS, Andrew Edward WALLER, Daniel John GALLAGHER, Daniel Mark BAKER, Manoj Kumar TYAGI, Joseph CAVANAUGH
