Publication number: 20230291061Abstract: Described herein are battery assemblies that comprise lithium-metal electrochemical cells and pressure-applying structures disposed adjacent to the cells and applying uniform pressure to the cells. Specifically, this uniform pressure is applied between a minimum threshold and a maximum threshold at any operating state of charge of these cells and, in some examples, over the entire operating lifetime of the cells. A pressure-applying structure can be positioned between a pair of adjacent cells or between a cell and an assembly enclosure. In some examples, the footprint of the pressure-inducing structure fully covers the footprint of the negative-electrode planar portion. The pressure-inducing structure may have a stress relaxation of less than 5% and/or a compression set of less than 10%. The pressure-inducing structure may remain in an elastic deformation region at any operating condition. In some examples, the pressure-inducing structure is foam or aerogel.Type: ApplicationFiled: March 8, 2022Publication date: September 14, 2023Applicant: Cuberg, Inc.Inventors: Seamus Bannon, Nadine Kuhn, Edward Meyjes, Stephen Lawes, Richard Wang, Chan Lojewski

Publication number: 20230253610Abstract: Described herein are battery assemblies that comprise lithium-metal electrochemical cells and lithium-ejecta containment components. A lithium-ejecta containment component is configured to prevent or at least reduce the migration of lithium metal that has been ejected from any of the lithium-metal electrochemical cells. For example, a lithium-ejecta containment component can be positioned between a pair of lithium-metal electrochemical cells and/or between the battery-assembly enclosure and each cell. In the same or other examples, a lithium-ejecta containment component can be integrated into the battery-assembly enclosure and/or cell enclosures. Furthermore, a lithium-ejecta containment component can be configured to absorb and contain the ejected lithium metal. In further examples, a lithium-ejecta containment component is configured to direct the ejected lithium metal away from the battery assembly.Type: ApplicationFiled: February 9, 2022Publication date: August 10, 2023Applicant: Cuberg, Inc.Inventors: Stephen Lawes, Edward Meyjes, Seamus Bannon, Alex Beraud, Luke Strohbehn, Richard Wang

Publication number: 20230138403Abstract: Methods and systems to train artificial intelligence modules are described, which protect privacy of sensitive data by virtue of the fact that the data source extracts blocks of partial data from the source item of content and distributes the extracted partial data to a plurality of processing nodes in an intermediate processing system. The processing nodes each perform an initial portion of the training process, for example by performing a convolution of the partial data, to produce a partial model. The partial models are transmitted to a merging module which amalgamates them and completes the training process to generate a global model for the AI task.Type: ApplicationFiled: March 26, 2021Publication date: May 4, 2023Inventors: Xiaoyu Richard Wang, Tao Zheng, Xin Wang

Publication number: 20210287277Abstract: A service may provide an e-commerce platform through which users may search for, view, and purchase products. To ensure users receive relevant results when querying for particular products or product classes, a list of ranked classes may be generated, from which the query results are based. For example, products may be classified into classes and particular text from search data may be associated with one or more of the products based on click log data. For instance, input text from previously performed queries may be associated with products interacted with following those queries (e.g., products clicked on to view/purchase). Training data that associates the particular text with the respective one or more classes into which the clicked on products are classified may be generated, and in response to receiving a query including the particular text as input, the list of ranked classes may be generated based on the training data.Type: ApplicationFiled: June 2, 2021Publication date: September 16, 2021Applicant: Target Brands, Inc.Inventors: VIKRAM SRINIVASAN, SRINIVASAN SESHADRI, RICHARD WANG
