Publication number: 20230049435Abstract: A multi-layer beverage container includes a multi-layer wall having an outer layer, a middle layer, and an inner layer. At least the inner layer is configured to flex inwards to accommodate a change in the sealed internal volume of the beverage container after a hot-filled beverage is filled inside the container and allowed to cool. The outer layer and inner layer delaminate from each other to accommodate this volume change, which allows the outer layer to retain its original shape. The middle layer functions to encourage delamination of the layers with respect to each other. A space corresponding to the volume change of the interior volume of the container is formed between the wall layers.Type: ApplicationFiled: August 13, 2021Publication date: February 16, 2023Inventors: Advait BHAT, Girish DESHPANDE, Brian HERSHAFT, David MCKELVEY, Shiyong YAN

Patent number: 9490980Abstract: Identity based encryption (IBE). An IBE server assigns a private and public key pair to a client device based on a unique identification of the client device. To establish an encrypted session with the client device a server device requests the client device's public key from the IBE server. Authentication of the client and the server by the IBE server is based on credentials or a token. Assigned keys are securely stored in an embedded trusted platform provided in the client device.Type: GrantFiled: February 27, 2013Date of Patent: November 8, 2016Inventor: Nachiket Girish Deshpande

Patent number: 7282238Abstract: A coherent material is formed on a substrate (10) by providing a precursor suspension (14) in which particulates are suspended in a carrier fluid, and directing the precursor suspension (14) at the substrate (10) from a first source (12). Generally contemporaneously with application of the deposited precursor suspension (14) to the surface, hot gases, e.g. hot gases produced by a flame (16), are directed at the substrate (10) from a remote second source (18) to fuse the particulates into the coherent material.Type: GrantFiled: June 27, 2001Date of Patent: October 16, 2007Assignee: nGimat Co.Inventors: Subramaniam Shanmugham, Andrew Tye Hunt, Girish Deshpande, Tzyy-Jiuan Jan Hwang, Erika Moore, Yongdong Jiang

Patent number: 7033637Abstract: Epitatial thin films for use as buffer layers for high temperature superconductors, electrolytes in solid oxide fuel cells (SOFC), gas separation membranes or dielectric material in electronic devices, are disclosed. By using CCVD, CACVD or any other suitable deposition process, epitaxial films having pore-free, ideal grain boundaries, and dense structure can be formed. Several different types of materials are disclosed for use as buffer layers in high temperature superconductors. In addition, the use of epitaxial thin films for electrolytes and electrode formation in SOFCs results in densification for pore-free and ideal gain boundary/interface microstructure. Gas separation membranes for the production of oxygen and hydrogen are also disclosed. These semipermeable membranes are formed by high-quality, dense, gas-tight, pinhole free sub-micro scale layers of mixed-conducting oxides on porous ceramic substrates. Epitaxial thin films as dielectric material in capacitors are also taught herein.Type: GrantFiled: January 12, 2000Date of Patent: April 25, 2006Assignee: MicroCoating Technologies, Inc.Inventors: Andrew Tye Hunt, Girish Deshpande, Wen-Yi Lin, Tzyy-Jiuan Jan

Patent number: 7031136Abstract: Tunable capacitors (10, 20, 30, 40) have a dielectric material (16, 26, 36, 42) between electrodes, which dielectric material comprises an insulating material (17, 27, 37, 42) and electrically conductive material, (18, 28, 38, 48) e.g., conductive nanoparticulates, dispersed therein. In certain cases, enhanced tune-ability is achieved when the dielectric material comprises elongated nanoparticulates (38). Further enhanced tune-ability may be achieved by aligning elongated particulates in an electrode-to-electrode direction. Nanoparticulates may be produced by heating passivated nanoparticulates. Passivated nanoparticulates may be covalently bound within a polymeric matrix. High bias potential device structures can be formed with preferential mobilities.Type: GrantFiled: April 9, 2002Date of Patent: April 18, 2006Assignee: nGimat Co.Inventors: Andrew Tye Hunt, Miodrag Oljaca, Scott Flanagan, Girish Deshpande, Stein Lee, Peter W.

Patent number: 6939576Abstract: Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol of polymer solution to a substrate and substantially simultaneously applying an energy source to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame that may optionally or desirably deposit material along with the polymer spray. One particular aspect of the invention is directed to production of polyimide films. In accordance with another aspect of the invention, the co-deposition process is used to provide thin polysiloxane coatings on glass and other substrates.Type: GrantFiled: June 27, 2001Date of Patent: September 6, 2005Assignee: nGimat Co.Inventors: Girish Deshpande, Andrew Tye Hunt, Subramaniam Shanmugham, Eric J. Yurtkuran, Todd Polley, Miodrag Oljara, Tzyy-Jiuan Jan Hwang, Aimee Poda, George Neuman

Publication number: 20030215644Abstract: Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol (N) of polymer solution to a substrate (30) and substantially simultaneously applying an energy source (38) to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame (38) that may optionally or desirably deposit material along with the polymer spray.

Patent number: 6368665Abstract: An improved chemical vapor deposition apparatus and procedure is disclosed. The technique provides improved shielding of the reaction and deposition zones involved in providing CVD coatings, whereby coatings can be produced, at atmospheric pressure, of materials which are sensitive to components in the atmosphere on substrates which are sensitive to high temperatures and which are too large, or inconvenient, to process in vacuum or similar chambers. The improved technique can be used with various energy sources and is particularly compatible with Combustion Chemical Vapor Deposition (CCVD) techniques.Type: GrantFiled: April 29, 1998Date of Patent: April 9, 2002Assignee: MicroCoating Technologies, Inc.Inventors: Andrew T.
