Publication number: 20230315996Abstract: Systems and methods for identifying data of interest are disclosed. The system may retrieve unstructured data from an internet data source via an alert system or RSS feed. The system may input the unstructured data into various models and scoring systems to determine whether the data is of interest. The models and scoring systems may be executed in order or in parallel. For example, the system may input the unstructured data into a Naïve Bayes machine learning model, a long short-term memory (LSTM) machine learning model, a named entity recognition (NER) model, a semantic role labeling (SRL) model, a sentiment scoring algorithm, and/or a gradient boosted regression tree (GBRT) machine learning model. Based on determining that the unstructured data is of interest, a data alert may be generated and transmitted for manual review or as part of an automated decisioning process.Type: ApplicationFiled: June 6, 2023Publication date: October 5, 2023Applicant: American Express Travel Related Services Company, Inc.Inventors: Ravi BATRA, Sandeep BOSE, Mario FRAGOSO, Ravneet GHUMAN, Madhu Sudan Reddy GUDUR, Suraj MADNANI, Curtis T.

Patent number: 11736966Abstract: In a wireless access node, Packet Data Convergence Protocol (PDCP) circuitry identifies a noise metric for the wireless access node. The PDCP circuitry receives Downlink (DL) user data for User Equipment (UE). The PDCP circuitry allocates a first portion of the DL data and a second portion of the DL data based on the noise metric. The PDCP circuitry transfers the first portion of the DL data over first Radio Link Control (RLC) circuitry to first MAC circuitry. The PDCP circuitry transfers the second portion of the DL data over second RLC circuitry to second MAC circuitry. The first MAC circuitry schedules wireless delivery of the first portion of the DL data and transfers the first portion of the DL data to the UE over first Physical Layer (PHY) circuitry. The second MAC circuitry schedules wireless delivery of the second portion of the DL data and transfers the second portion of the DL data to the UE over second PHY circuitry.Type: GrantFiled: May 4, 2021Date of Patent: August 22, 2023Assignee: T-MOBILE INNOVATIONS LLCInventors: Sreekar Marupaduga, Ravi Varma Kallepalli, Rajveen Narendran

Patent number: 11582765Abstract: A Radio Access Network (RAN) wirelessly serves a User Equipment (UE) over a frequency channel based on a radio signal metric. The RAN comprises baseband circuitry and a radio. The baseband circuitry determines when multiple Physical Cell Identifiers (PCIs) are available to serve the UE. In response, the baseband circuitry selects some resource blocks in the frequency channel and generates a UE instruction to measure the radio signal metric for the selected resource blocks. The radio receives the UE instruction for the baseband circuitry and wirelessly transfers the UE instruction to the UE. The radio wirelessly receives a measurement report from the UE that indicates the radio signal metric for the selected resource blocks. The radio transfers the measurement report to the baseband circuitry. The baseband circuitry receives the measurement report and responsively schedules the UE in the selected resource blocks based on the radio signal metric.Type: GrantFiled: January 15, 2021Date of Patent: February 14, 2023Assignee: T-MOBILE INNOVATIONS LLCInventors: Anirudh Krishna, Sreekar Marupaduga, Ravi Varma Kallepalli, Maher Ahmad Hasan, Vladyslav Bereslavskyy

Patent number: 11246973Abstract: A drainage bag is provided for a thermal control unit adapted to deliver temperature-controlled liquid to a patient in order to control the patient's temperature. The drainage bag is used to hold and transport the liquid when the liquid inside the thermal control unit is changed. The drainage bag includes a bottom layer, a top layer sealed thereto, and a float secured to the top layer that is positioned adjacent an opening in the top layer. As the liquid from the thermal control unit drains into the opening in the top layer, the liquid lifts the float and the float lifts the top layer of the bag. The bag thereby expands its volume to accommodate the liquid from the thermal control unit. The bag may further be designed to be carried without sealing the opening and without spilling the liquid. A method for using the bag is also disclosed.Type: GrantFiled: January 31, 2019Date of Patent: February 15, 2022Assignee: Stryker CorporationInventors: Ryan Ariel Alvarez, Venkata Ravi Varma Mudunuri, Teresa Lynn Miller, Jack Louis Leckner, Alexey Titov
