Publication number: 20220238300Abstract: Methods and systems for rating a current substrate support assembly based on impedance circuit electron flow are provided. Data associated with an amount of radio frequency (RF) power flowed through an electrical component of a current substrate support assembly during a current testing process performed for the current substrate support assembly is provided as input to a trained machine learning model. One or more outputs of the trained machine learning model are obtained. A measurement value for an electron flow across an impedance circuit of the current substrate support assembly is extracted from the one or more outputs. In response to a determination that the extracted measurement value for the electron flow satisfies an electron flow criterion, a first quality rating is assigned to the current substrate support assembly.Type: ApplicationFiled: January 26, 2021Publication date: July 28, 2022Inventors: Arvind Shankar Raman, Harikrishnan Rajagopal, John Forster

Patent number: 10776030Abstract: An system for quota arbitration of a distributed file system (DFS) may obtain a current amount of storage used by a given quota entity on storage segments of the DFS, the given quota entity having a global quota for the DFS and each of the storage segments being assigned a respective first quota limit for the given quota entity. The system may determine a global available quota amount for the given quota entity across all the storage segments based on the obtained current amounts of storage used by the given quota entity and the global quota, and provision of a respective second quota limit for the given quota entity to each of the plurality of storage segments, based on a division of all or less than all of the global available quota amount.Type: GrantFiled: March 30, 2016Date of Patent: September 15, 2020Assignee: Hewlett Packard Enterprise Development LPInventors: Kishore Kumar Muppirala, Shankar Raman, Narayanan Ananthakrishnan Nellayi

Patent number: 10635643Abstract: Examples include, in response to fulfillment of a tiering policy, dividing, by a cloud provider engine of a computing device, data blocks of a filesystem object into data chunks. Some examples comprise generating, by the cloud provider engine, a current manifest file in a local memory and causing the cloud storage system to generate a current pseudo folder in the cloud storage system corresponding to a particular epoch of the filesystem object. Some other examples comprise tiering, by the cloud provider engine, the data chunks and the current manifest file to the current pseudo folder, the current manifest including pointers to the data chunks corresponding to the filesystem object at the particular epoch.Type: GrantFiled: January 19, 2017Date of Patent: April 28, 2020Assignee: HEWLETT PACKARD ENTERPRISE DEVELOPMENT LPInventors: Priya Pappanaickenpalayam Muthuswamy, Vitaly Oratovsky, Arul Kumar Sivalingam, Shankar Raman, Manny Ye

Patent number: 8111828Abstract: A management system generates a sequence of keys and an identifier of each key in the sequence. A current key in the sequence and the identifier of the current key are transferred from the management system to a storage system. The storage system encrypts the data into encrypted data using the current key. The storage system stores the identifier and the encrypted data. The identifier and the encrypted data are retrieved from the storage system. The key in the sequence identified by the identifier is transferred from the management system to the storage system. The storage system decrypts the encrypted data using the decryption key.Type: GrantFiled: July 31, 2007Date of Patent: February 7, 2012Assignee: Hewlett-Packard Development Company, L.P.Inventors: Shankar Raman, Kiran Kumar Malle Gowda

Publication number: 20110106193Abstract: A jacket of biological compatible material has an internal volume dimensioned for an apex of the heart to be inserted into the volume and for the jacket to be slipped over the heart. The jacket has a longitudinal dimension between upper and lower ends sufficient for the jacket to surround a lower portion of the heart with the jacket surrounding a valvular annulus of the heart and further surrounding the lower portion to cover at least the ventricular lower extremities of the heart. The jacket is adapted to be secured to the heart with the jacket surrounding at least the valvular annulus and the ventricular lower extremities. The jacket is adjustable on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain circumferential expansion of the heart beyond the maximum adjusted volume during diastole and to permit unimpeded contraction of the heart during systole.Type: ApplicationFiled: January 10, 2011Publication date: May 5, 2011Applicant: MARDIL, INC.Inventors: Clifton A.

Patent number: 7854000Abstract: A method for addressing attacks on a computer connected to a network includes receiving at a router a TCP SYN request to be screened. The method also includes comparing the received TCP SYN request to be screened to at least one stored tuple representative of one or more SYN requests previously received at the router and determining that the received TCP SYN request to be screened matches the stored tuple. In response to determining that the received TCP SYN request to be screened matches the stored tuple, the TCP SYN+ACK response is prevented from being sent by the router in response to the TCP SYN request to be screened.Type: GrantFiled: October 26, 2004Date of Patent: December 14, 2010Assignee: Cisco Technology, Inc.Inventors: Balaji Venkat, Srinivas Subramanian, Venkat Ramani, Shankar Raman
