Patent number: 11964436Abstract: In an example, a method includes operating, by a processor, on object model data and operating, on a processor, on pattern data. The object model data describes at least part of an object to be generated in additive manufacturing and the pattern data describes an object pattern intended to be formed on at least a portion of the part of the object to be generated in additive manufacturing. The method includes determining, by a processor, control data to control a print agent applicator to apply a pattern of fusing agent onto a part of a layer of build material. The pattern of fusing agent comprises a fusing agent area and a gap area that lacks fusing agent. The gap area corresponds to the object pattern such that no fusing agent is applied to a part of the layer of build material that corresponds to the object pattern.Type: GrantFiled: December 20, 2022Date of Patent: April 23, 2024Assignee: Hewlett-Packard Development Company, L.P.Inventors: Wei Huang, Gary J.

Patent number: 11968238Abstract: A distributed policy management (PM) system (e.g., system for authentication, authorization, and accounting (AAA) activities on a network) is provided. Nodes of the PM system may share information of the PM system using a distributed data store (e.g., a multi-master cache). Each node of the distributed PM system may further share information from the distributed data store with other nodes of a corporate infrastructure network by augmenting information in a remote authentication dial-in user service (RADIUS) protocol message. Nodes that are involved in policy management (e.g., network authentication server (NAS) or firewall) without access to the distributed data store may receive information via augmented RADIUS messages. In this manner, devices may be interfaced to the distributed PM system without having access to the distributed data store. High availability and load balancing implementations may be provided by leveraging the distributed data store across nodes of the PM system.Type: GrantFiled: August 30, 2022Date of Patent: April 23, 2024Assignee: Hewlett Packard Enterprise Development LPInventors: Antoni Milton, Pattabhi Attaluri

Patent number: 11966818Abstract: Decentralized machine learning to build models is performed at nodes where local training datasets are generated. A blockchain platform may be used to coordinate decentralized machine learning (ML) over a series of iterations. For each iteration, a distributed ledger may be used to coordinate the nodes communicating via a blockchain network. A node can include self-healing features to recover from a fault condition within the blockchain network in manner that does not negatively impact the overall learning ability of the decentralized ML system. During self-healing, the node can determine that a local ML state is not consistent with the global ML state and trigger a corrective action to recover the local ML state. Thereafter, the node can generate a blockchain transaction indicating that it is in-sync with the most recent iteration of training, and informing other nodes to reintegrate the node into ML.Type: GrantFiled: February 21, 2019Date of Patent: April 23, 2024Assignee: Hewlett Packard Enterprise Development LPInventors: Sathyanarayanan Manamohan, Krishnaprasad Lingadahalli Shastry, Vishesh Garg
