Patent number: 11848269Abstract: A system and method for creating layout for standard cells are described. In various implementations, a floating metal net in the metal zero layer of a standard cell is selected for conversion to a power rail. The metal zero layer is a lowest metal layer above the gate region of a transistor. A semiconductor process (or process) forms a power rail in a metal zero track reserved for power rails. The process forms another power rail in a metal zero track reserved for floating metal nets, and electrically shorts the two power rails using a local interconnect layer between the two power rails. The charging and discharging times of a source region physically connected to the two power rails decreases.Type: GrantFiled: October 4, 2021Date of Patent: December 19, 2023Assignee: Advanced Micro Devices, Inc.Inventors: Partha Pratim Ghosh, Pratap Kumar Das, Prasanth M

Patent number: 11842800Abstract: Temperature measurement is an important part of many potential applications in process industry. Conventional temperature measurement methods require manual intervention for process monitoring and fail to provide accurate and precise measurement of temperature of an enclosed mixed fluid chamber. The present disclosure provides artificial intelligence based temperature measurement in mixed fluid chamber. A plurality of inputs pertaining to the mixed fluid chamber are received to build a fluid based model. The fluid based model is used to generate one or more fluid parameters. The one or more fluid parameters are used along with a ground truth temperature data and the received plurality of inputs for training an artificial intelligence (AI) based model. However, the AI based model is trained with and without knowledge of fluid flow. The trained AI based model is further used to accurately estimate temperature of the mixed fluid chamber for a plurality of test input data.Type: GrantFiled: July 8, 2020Date of Patent: December 12, 2023Assignee: TATA CONSULTANCY SERVICES LIMITEDInventors: Rajat Kumar Das, Arijit Sinharay, Arijit Chowdhury, Tapas Chakravarty, Arpan Pal

Patent number: 11802801Abstract: This disclosure relates to a system and method for measuring average temperature of mixed fluid in an enclosed chamber. Measurement is based on two independent principle as measuring variation in acoustic wave velocity and variation in resistivity that works on a single setup. First principle is based on measuring acoustic wave velocity in a known medium, which is isolated from the surrounding. The system comprises a primary pipe and a secondary pipe, wherein the ends of the pipes reside inside the enclosed chamber. The primary pipe is made out of good conductor of heat and filled with air. Ends of the primary pipe is fitted with a transducers have one transmitter at one end and one receiver at another end. Average temperature of the mixed fluid is measured based on the variations in sound velocity of acoustic wave passed through the primary pipe and resistivity variations of the primary pipe.Type: GrantFiled: December 4, 2020Date of Patent: October 31, 2023Assignee: TATA CONSULTANCY SERVICES LIMITEDInventors: Arijit Sinharay, Rajat Kumar Das, Anwesha Khasnobish, Tapas Chakravarty

Patent number: 11799826Abstract: Techniques and technologies for an IP address management (IPAM) system to monitor the usage of IP addresses across regions in one or more networks of resources. The IPAM system may be used to allocate IP addresses to resources in networks and track what IP addresses are being used by resources or available for allocation. The IPAM system may periodically obtain usage information that indicates actual, current IP address usage by the resources in the networks, identify differences between the current IP address usage and an inventory maintained by the IPAM service, and reconcile the differences. Additionally, the IPAM system may further respond to network administrator queries about their resource and IP address usage. Further, the IPAM system may emit various utilization metrics to the network administrators which may be tied to alarms or alerts around non-compliant resources or IP addresses.Type: GrantFiled: November 24, 2021Date of Patent: October 24, 2023Assignee: Amazon Technologies, Inc.Inventors: Samuel Lough, John Jeffrey Schlachtenhaufen, Masood Karimi, Eric Andrew Rubin-Smith, Shovan Kumar Das, Joshua D Leaverton, Jonathan Paul Kramer

Patent number: 11784967Abstract: Techniques implemented by an IP address management (IPAM) system for monitoring the usage of IP addresses in networks of computing resources and automatically notifying networking devices when IP address usage has changed. The IPAM system may create pools of IP addresses (e.g., address groups), and map those pools to prefix lists that are distributed to the networking devices. The IPAM system may monitor changes in IP address usage by resources in the networks (e.g., allocations and releases of IP addresses), update the pools that are affected by the changes, carry those changes through to the appropriate prefix lists, and propagate updated prefix lists to the networking devices (e.g., firewall devices, routing devices, etc.). In this way, the IPAM system may automatically identify and apply IP address changes to prefix lists that are used for networking operations in the networks.Type: GrantFiled: September 27, 2022Date of Patent: October 10, 2023Assignee: Amazon Technologies, Inc.Inventors: Eric Andrew Rubin-Smith, Leonid Nikolayev, Shovan Kumar Das
