Publication number: 20240119405Abstract: Systems, method and computer readable medium are provided for automated storage and retrieval. User authentication information is received via a user interface for a dynamic storage and retrieval device. The user identity is verified based upon the authentication information and previously stored authentication data. Order information is retrieved for an order associated with the user following the verifying of user identity, the order information indicating one or more locations for items associated with the order. Instructions are transmitted to initiate a physical opening of at least one of the dynamic storage and retrieval device and at least one static storage location to enable the user to retrieve at least one item of the order, the static storage location including a controller controlling a locking mechanism and communicatively coupled to the dynamic storage and retrieval device.Type: ApplicationFiled: December 19, 2023Publication date: April 11, 2024Inventors: Paul Edward Durkee, Stuart William Clark, Colin Holmes, Jason D.

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: 6333378Abstract: A water-based latex of an acrylic-modified waterborne alkyd or uralkyd dispersion in water is described. The acrylic-modified waterborne alkyd or uralkyd is a hybrid resin prepared by the polymerization of at least one latent oxidatively-functional (LOF) acrylic monomer in the presence of a waterborne alkyd or uralkyd. Alternatively, the acrylic-modified waterborne alkyd or uralkyd is a hybrid resin prepared by shearing a mini-emulsion based on a solvent-borne alkyd or uralkyd dissolved in at least one LOF acrylic monomer. Preparation of the latexes may be achieved by emulsion polymerization of at least one latent oxidatively-functional acrylic monomer in the presence of a waterborne alkyd or uralkyd whereby the latent oxidative functionality of the acrylic polymer survives polymerization.Type: GrantFiled: May 28, 1999Date of Patent: December 25, 2001Assignee: Eastman Chemical CompanyInventors: Mark D. Clark, Bradley J. Helmer, Glenn L. Shoaf

Patent number: 6262149Abstract: A water-based latex of an acrylic-modified waterborne alkyd dispersion in water is described. The acrylic-modified waterborne alkyd is a hybrid resin prepared by the polymerization of at least one ethylenically unsaturated monomer in the presence of a waterborne alkyd having at least one pendant sulfonate functionality. The ethylenically unsaturated monomer may also be a latent oxidatively functional (LOF) acrylic monomer. Preparation of the latexes may be achieved by emulsion polymerization of at least one ethylenically unsaturated monomer in the presence of a waterborne alkyd having at least one pendant sulfonate functionality. Preparation of hybrid latexes which contain latent oxidative functional (LOF) acrylic monomers may also be achieved by emulsion polymerization of at least one LOF acrylic monomer in the presence of a waterborne alkyd having at least one pendant sulfonate functionality whereby the latent oxidative functionality of the acrylic polymer survives polymerization.Type: GrantFiled: August 12, 1998Date of Patent: July 17, 2001Assignee: Eastman Chemical CompanyInventors: Mark D.

Patent number: 5539073Abstract: This invention provides polymers useful in coating compositions. The polymers are prepared via a free radical polymerization using ethylenically unsaturated monomers. The polymers of this invention possess pendant allylic groups which are capable of effecting free-radical flux when the compositions are applied to a substrate and exposed to oxygen. Coatings formed from preferred compositions possess superior solvent, print, and block resistance.Type: GrantFiled: April 12, 1995Date of Patent: July 23, 1996Assignee: Eastman Chemical CompanyInventors: James W. Taylor, Martha J. Collins, Mark D. Clark
