Patent number: 11188831Abstract: In response to a programmatic interaction, respective representations of items of an initial result set are presented to an item consumer. One or more result refinement iterations are then conducted. In a given iteration, one or more feedback indicators with respect to one or more items are identified, a machine learning model is trained using at least the feedback indicators to generate respective result set candidacy metrics for at least some items, and the metrics are then used to transmit additional items for presentation to the item consumer.Type: GrantFiled: October 27, 2017Date of Patent: November 30, 2021Assignee: Amazon Technologies, Inc.Inventors: Benjamin Lev Snyder, Liliane Jeanne Barbour, Aritra Biswas, Simone Elviretti, Rasika Sanjay Jangle, Paul Hercules Mandac Rivera, James Stevenson, Daniel Patrick Weaver

Patent number: 11027527Abstract: A low-emissivity (low-E) coating on a substrate (e.g., glass substrate) includes at least first and second infrared (IR) reflecting layers (e.g., silver based layers) that are spaced apart by contact layers (e.g., NiCr based layers), a layer comprising silicon nitride, and an absorber layer of or including a material such as niobium zirconium which may be oxided and/or nitrided. The absorber layer is designed to allow the coated article to realize glass side reflective (equivalent to exterior reflective in an IG window unit when the coating is provided on surface #2 of an IG window unit) silver color. In certain example embodiments, the coated article (monolithic form and/or in IG window unit form) has a low visible transmission (e.g., from 15-45%, more preferably from 22-39%, and most preferably from 24-35%). In certain example embodiments, the coated article may be heat treated (e.g., thermally tempered and/or heat bent).Type: GrantFiled: October 18, 2016Date of Patent: June 8, 2021Assignees: GUARDIAN GLASS, LLC, GUARDIAN GLASS HOLDING S.P.C.Inventors: Aritra Biswas, Brent Boyce, Allen Chu, Philip J. Lingle, Kenneth Lord, Muniswami Naidu, Venkata Krishnaswamy Naidu Vantaku

The absorber layer is designed to allow the coated article to realize glass side reflective (equivalent to exterior reflective in an IG window unit when the coating is on surface #2 of the IG unit) grey color. In certain example embodiments, the coated article (monolithic form and/or in IG window unit form) has a low visible transmission (e.g., from 20-45%, more preferably from 22-39%, and most preferably from 25-37%). In certain example embodiments, the coated article may be heat treated (e.g., thermally tempered and/or heat bent).Type: GrantFiled: October 18, 2016Date of Patent: March 16, 2021Assignees: GUARDIAN GLASS HOLDING S.P.C., GUARDIAN GLASS, L.L.CInventors: Aritra Biswas, Brent Boyce, Allen Chu, Philip J.

Patent number: 10766808Abstract: This invention relates to a coated article including a low-emissivity (low-E) coating. In certain example embodiments, the low-E coating is provided on a substrate (e.g., glass substrate) and includes at least first and second infrared (IR) reflecting layers (e.g., silver based layers) that are spaced apart by contact layers (e.g., NiCr based layers) and a dielectric layer of or including a material such as silicon nitride. The dielectric layer is split by a layer of or including zirconium oxide, in order to improve durability. In certain example embodiments, the coated article has a low visible transmission (e.g., no greater than 60%, more preferably no greater than about 55%, and most preferably no greater than about 50%).Type: GrantFiled: October 18, 2016Date of Patent: September 8, 2020Assignees: GUARDIAN GLASS HOLDING S.P.C., GUARDIAN EUROPE S.A.R.L.Inventors: Aritra Biswas, Bernd Disteldorf, Rajendran Venkatesan

Patent number: 10590034Abstract: Coated articles for use in backsplash applications such as kitchen backsplashes, bathroom backsplashes, and bathroom floor/wall applications. The coated article includes a coating on a glass substrate, where the coating includes a plurality of dielectric layers and a plurality of metal-based layers and is configured so that the coated article has desirable glass side reflective coloration (e.g., bronze, blue, silver, and/or grey coloration) and is sufficiently opaque to hide adhesive used to adhere the coated article to walls/floors. The coating may be configured to realize thermal stability in order to have minimal or reduced glass side reflective color shift up heat treatment (e.g., thermal tempering).Type: GrantFiled: December 16, 2016Date of Patent: March 17, 2020Assignee: GUARDIAN GLASS HOLDING S.P.C.Inventors: Aritra Biswas, Gpoal Balachandran
