Patent number: 11588755Abstract: Information describing changes to a collection of items maintained by a database may be stored in a log file. The information in the log file may be converted into a stream of records describing the changes. The records may be directed to a computing node selected for performing a trigger function in response to the change, based on applying a hash function to a portion of the record, identifying a hash space associated with a value output by the hash function, and mapping from the hash space to the selected computing node.Type: GrantFiled: January 31, 2022Date of Patent: February 21, 2023Assignee: Amazon Technologies, Inc.Inventors: Parikshit Shivajirao Pol, Subramanian Sankara Subramanian, Rajaprabhu Thiruchi Loganathan, Rama Krishna Sandeep Pokkunuri, Gopinath Duddi, Akshat Vig, Safeer Mohiuddin, Sudarshan Narasimhan

Publication number: 20220125999Abstract: A synthetic polyisoprene latex emulsion has pre-vulcanization composition and post vulcanization composition. The pre-vulcanization composition comprises insoluble amorphous sulfur extracted with zinc dithiocarbamate catalyst at 20° C. to form sulfur chain and transported to interior of synthetic polyisoprene particle forming physical attachment of sulfur to active sites. The degree of pre-vulcanization is verified by expansion of cast and dried film of latex in toluene in 20 minutes by means of a swelling index test. The latex emulsion is vulcanized at 90° C. to 120° C. for 3 to 5 minutes. Post-vulcanization composition with accelerators crosslink between synthetic polyisoprene particles, uniformly curing both in the inter-particle and intra-particle regions to produce high cross link density, uniform distribution of double bonds with zinc segregation at the boundaries of original particles.Type: ApplicationFiled: October 22, 2020Publication date: April 28, 2022Applicant: Thai Nippon Rubber Industry Public Company LimitedInventors: Pathompong Chupayak, Theeraphol Piachan, Supparat Piachan, Brian Youichi Kempimook, Punyawat Chupayak, Waranyu Dararattanaroj, Dave Narasimhan, Sudarshan Narasimhan

Publication number: 20210337930Abstract: A shoe cover is a natural latex article with reduced amount of sulfur cross linking agent and accelerators including zinc dithiocarbamate that break catalytically soluble sulfur S8 sulfur rings forming sulfur linear chains. Surfactants present in the pre-vulcanization composition wets natural polyisoprene particles and permeates small sized sulfur into the interior of these particles thereby pre-vulcanizing the particles. The latex emulsion also has post-vulcanization composition with accelerators that crosslink between particles during the post vulcanization cure cycle. The dipped natural polyisoprene article is substantially uniformly cured both in the inter-particle and intra-particle regions and reliably exhibits high cross link density, uniform distribution of double bonds and zinc segregation at the boundaries or original particles. The natural rubber films exhibit high tensile strength, tensile modulus, tear strength, elongation with low modulus of the shoe cover.Type: ApplicationFiled: April 29, 2020Publication date: November 4, 2021Applicant: UA Thomas Co.

Patent number: 10165792Abstract: The hunger minimized fasting system relies on providing a blood glucose level at all times in the range of 5 to 10 mM, satisfying glucose needs of the brain and metabolizing blood glucose through anaerobic glycolysis to release ATP at the extramitocontrial portion of the cell. Consuming only solid free nutrient liquids eliminates brain hunger response. Liquids consumed during fasting include solid filtered vegetable soup and clear fruit juices of 8 to 12 ounces taken every 2 to 4 hours having calorie deficiency of 600 to 1400 as compared to minimal daily calorie requirements for an adult. Fat released from storage is metabolized by ATP produced by glycolysis at the extramitocontrial location and enters the interior of the mitochondria, enabling the TCA cycle. Weight loss observed during fasting is about one half to one pound per day.Type: GrantFiled: July 27, 2016Date of Patent: January 1, 2019Inventors: Sudarshan Narasimhan, Dave Narasimhan

Patent number: 8995119Abstract: Provided herein is a low cost high performance light weight hard drive cover that is injection molded. The hard drive top cover has a flange portion that applies pressure to an elastomeric seal preventing ingress of moisture dust and other contaminants into the sensitive components. The flange portion is reinforced with a plurality of metallic strips that are placed between pressure application locations embedded within the polymer flange. The viscoelastic creep response of the polymer flange does not contribute to relaxation of pressure on the elastomeric seal due to the presence of the metallic reinforcement strips. The metallic reinforcement strips may have a convex curvature between pressure application locations. The metallic reinforcement strip may have apertures for passage of injection molded polymer creating delamination free intimate bond between the polymer in the flange and the metallic reinforcement strip.Type: GrantFiled: March 17, 2009Date of Patent: March 31, 2015Assignee: MMI Precision Forming Pte Ltd.Inventors: Hendrikus Thijssen, Sudarshan Narasimhan
