Patent number: 12170597Abstract: A system implements a cloud-based digital platform allows developers to build new applications/services and then deploy to cloud platforms among continuous deployment, A/B test, blue/green deployment, and canary deployment. The system configures a service mesh on top of a cluster of computers. The system initializes a new service via templates that include common libraries, security scan pipeline, monitoring as code pipeline, and code coverage management for internal policy compliances, as well automated cloud resources request and provisioning. One or more proxy services, that extract data from the data sources using filters, can be executed. The system may use machine learning based models that are trained using the data extracted by the proxy service. The system allows automatic provisioning, computation orchestration, storage requests, and artificial intelligence insight feedback, as well as automated self-services to navigate complex systems and reduce on-boarding times of the platform.Type: GrantFiled: October 6, 2022Date of Patent: December 17, 2024Assignee: Humana Inc.Inventors: Tom Ho, Guan Wang, Subramanyam Nakka

Patent number: 12135732Abstract: A system performs delivery of a data pipeline on a cloud platform. The system receives a specification of the data pipeline that is split into smaller specifications of data pipeline units. The system identifies a target cloud platform and generates a deployment package for each data pipeline unit for the target cloud platform. The system creates a connection with the target cloud platform and uses the connection to provision computing infrastructure on the target cloud platform for the data pipeline unit according to the system configuration of the data pipeline unit. The data pipeline may be implemented as a data mesh that is a directed acyclic graph of nodes, each node representing a data pipeline unit. Different portions of the data mesh may be modified independent of each other. Partial results stored in different portions of the data mesh may be recomputed starting from different points in time.Type: GrantFiled: May 24, 2023Date of Patent: November 5, 2024Assignee: Humana Inc.Inventors: Yuan Yao, Andrew McPherron, Tom Ho, Bing Zhang

Patent number: 8692297Abstract: A power and ground shield mesh to remove both capacitive and inductive signal coupling effects of routing in integrated circuit device. An embodiment describes the routing of a shield mesh of both power and ground lines to remove noise created by capacitive and inductive coupling. Relatively long signal lines are routed in between fully connected power and ground shield mesh which may be generated by a router during the signal routing phase or during power mesh routing phase. Leaving only the odd tracks or the even tracks for signal routing, power mesh (VDD) and ground mesh (VSS) are routed and fully interconnected leaving shorter segments and thereby reducing the RC effect of the circuit device. Another embodiment presents a technique where the signals are shielded using the power and ground mesh for a gridless routing. Another embodiment presents a multi-layer grid routing technique where signals are routed on even grid and the power and ground lines are routed on odd grid.Type: GrantFiled: August 2, 2010Date of Patent: April 8, 2014Assignee: Synopsys, Inc.Inventor: Iu-Meng Tom Ho
