Publication number: 20240246048Abstract: An apparatus includes a blender lid configured to cover an opening in a blender receptacle and a lid arm coupled to the blender lid and coupled rotationally about a first horizontal axis. The lid arm is configured to rotate about the first horizontal axis to selectively position the blender lid to cover and uncover the opening in the blender receptacle. The blender arm may rotate the blender lid about the first horizontal axis to cover the opening in the blender receptacle and apply a downward force on the blender lid to seal the opening of the blender receptacle with the blender lid. The blender arm may include a horizontal rod having a longitudinal axis that corresponds to the first horizontal axis and having a first end attached to the blender lid.Type: ApplicationFiled: April 4, 2024Publication date: July 25, 2024Inventors: Vipin JAIN, Venkateswaran AYALUR, Vijayasimha DODDABALAPUR, Kevin Andrew MARSHALL

Publication number: 20240247366Abstract: Disclosed herein are bonded diamond composites that may include a ceramic composite layer, a diamond film layer, and a silicon carbide bonding layer bonding the diamond film layer to the ceramic composite layer. Example ceramic composite layers disclosed herein include diamond particles within a silicon carbide matrix. Methods of making bonded diamond composites through infiltration bonding are disclosed herein. Example methods include exposing a ceramic preform to molten silicon such that the silicon infiltrates into and through the silicon preform to a diamond film interfaced with the ceramic preform. Example methods include reacting the silicon with the ceramic preform and the diamond film to form a silicon carbide bonding layer bonding the diamond film to the resulting ceramic composite layer.Type: ApplicationFiled: January 23, 2023Publication date: July 25, 2024Inventors: Andrew Marshall, Glenn EVANS, Samuel SALAMONE, Michael AGHAJANIAN

Publication number: 20240179181Abstract: A system and method for authorization policy evaluation. Authorization policies are authored in a general-purpose authorization language. An evaluation engine is used in a provider network by application developers to manage access within their applications based on fine-grained permissions. The policy language combines elements of role-based and attributed-based access control within an intuitive syntax and efficient evaluation strategy. The policy syntax separates role-based expressions of a policy from attribute-based expressions of the policy.Type: ApplicationFiled: November 28, 2022Publication date: May 30, 2024Inventors: Emina TORLAK, Darin MCADAMS, Neha RUNGTA, Michael W. HICKS, Craig Ryan DISSELKOEN, Aaron Joseph ELINE, John Holman KASTNER, Kyle HEADLEY, Anwar MAMAT, Richard Matthew MCCUTCHEN, Andrew Marshall WELLS, Kesha Hanne HIETALA, Shaobo HE, Mark Edward STALZER, Julian LOVELOCK

Publication number: 20240179188Abstract: A system and method for authorization policy analysis. A policy analyzer answers first-order questions about authorization policies by reducing the policies to Satisfiability modulo theories (SMT). Input to the analyzer includes a policy to be analyzed and a schema for that policy. If the policy passes strict validation against the schema, then the analyzer symbolically evaluates the policy to encode its semantics as an SMT expression. The SMT expression is used for formulate a desired query about policy behavior such as, for example, if there is any input on which two policies both evaluate to true. The reduction to SMT produces a quantifier-free formula in a combination of decidable theories to support large scale deployments. This reduction is achieved by focusing the analysis on policies that pass strict validation, rather than attempting to analyze arbitrary policies.Type: ApplicationFiled: November 28, 2022Publication date: May 30, 2024Inventors: Emina TORLAK, Kyle HEADLEY, Michael W. HICKS, Neha RUNGTA, Andrew Marshall WELLS

Patent number: 11978038Abstract: Methods and systems for digital hot wallet protection are provided. A payment channel is established via a Layer-2 network of a cryptocurrency blockchain for transferring a cryptocurrency balance from a first digital wallet of a service provider to a second digital wallet of a trusted entity over a plurality of commitment transactions. A transaction receipt for each commitment transaction is transmitted to the trusted entity via a secure communication channel previously established between the service provider and the trusted entity outside of the Layer-2 network. A transaction log of the service provider is modified so that it no longer represents the current transaction state of the payment channel Responsive to detecting a breach of the first wallet, a transaction is broadcast to a Layer-1 network of the blockchain for transferring the total cryptocurrency balance from the first wallet to the second wallet.Type: GrantFiled: May 6, 2022Date of Patent: May 7, 2024Assignee: PAYPAL, INC.Inventors: Jakub Burgis, Raoul Johnson, Andrew Marshall, Muhammad Saad
