Patent number: 11931956Abstract: This invention teaches a multi-sensor quality inference system for additive manufacturing. This invention still further teaches a quality system that is capable of discerning and addressing three quality issues: i) process anomalies, or extreme unpredictable events uncorrelated to process inputs; ii) process variations, or difference between desired process parameters and actual operating conditions; and iii) material structure and properties, or the quality of the resultant material created by the Additive Manufacturing process. This invention further teaches experimental observations of the Additive Manufacturing process made only in a Lagrangian frame of reference. This invention even further teaches the use of the gathered sensor data to evaluate and control additive manufacturing operations in real time.Type: GrantFiled: September 13, 2022Date of Patent: March 19, 2024Assignee: DIVERGENT TECHNOLOGIES, INC.Inventors: Vivek R. Dave, David D. Clark, Matias Roybal, Mark J. Cola, Martin S. Piltch, R. Bruce Madigan, Alberto Castro

Patent number: 7522762Abstract: An image analysis workstation for analyzing optical thin film arrays is disclosed. One disclosed embodiment relates to individual arrays that comprise a single optical thin film test surface that provides a plurality of discretely addressable locations, each comprising an immobilized capture reagent for an analyte of interest. These are referred to herein as “arrayed optical thin film test surfaces.” Preferably, an individual arrayed optical thin film test surface comprises at least 4, more preferably at least 16, even more preferably at least 32, still more preferably at least 64, and most preferably 128 or more discretely addressable locations. One or more of the discretely addressable locations may provide control signals (e.g., for normalizing signals and/or that act as positive and/or negative controls) or fiducial signals (i.e., information that is used to determine the relative alignment of the arrayed optical thin film test surface within the device.Type: GrantFiled: April 16, 2003Date of Patent: April 21, 2009Assignee: Inverness Medical-Biostar, Inc.Inventors: Larry Rea, David D.

Patent number: 7256707Abstract: A modulated reflectance well telemetry apparatus having an electrically conductive pipe extending from above a surface to a point below the surface inside a casing. An electrical conductor is located at a position a distance from the electrically conductive pipe and extending from above the surface to a point below the surface. Modulated reflectance apparatus is located below the surface for modulating well data into a RF carrier transmitted from the surface and reflecting the modulated carrier back to the surface. A RF transceiver is located at the surface and is connected between the electrically conductive pipe and the electrical conductor for transmitting a RF signal that is confined between the electrically conductive well pipe and the electrical conductor to the modulated reflectance apparatus, and for receiving reflected data on the well from the modulated reflectance apparatus.Type: GrantFiled: June 18, 2004Date of Patent: August 14, 2007Assignee: Los Alamos National Security, LLCInventors: David D. Clark, Don M. Coates

Patent number: 6656428Abstract: The present invention relates to cost effective analytical instruments for determining the presence or amount of an analyte in a sample. The analytical instruments utilize an assay cartridge which has a sample receiving port and a rotatable carousel containing a plurality of reagent wells. Each reagent well includes a piston element for delivery of reagent to a test surface. The instrument is capable of indexing the assay cartridge to deliver sample and reagents to a test surface in a predetermined and flexibile manner, thus providing an assay protocol which is specific to the type of sample under analysis. The invention also relates to components, features, disposables, reagent delivery systems, accessories, and methods for using such instruments. Appropriate applications include infectious disease testing, cancer detection and monitoring, therapeutic drug level monitoring, allergy testing, environmental testing, food testing, diagnostic testing of human and veterinary samples, and off-line process testing.Type: GrantFiled: August 3, 2000Date of Patent: December 2, 2003Assignee: Thermo Biostar, Inc.Inventors: David D.
