Publication number: 20240089905Abstract: Aspects presented herein may enhance the accuracy and/or latency of UE positioning based on crowd-sourcing, where a network entity may compute a position estimate of a UE based on neighbor-cell scan data from the UE and one or more reference UEs. In one aspect, a network entity receives a first set of measurements associated with at least one cell from a UE. The network entity performs a position estimation of the UE based on at least one of the first set of measurements associated with the at least one cell, a second set of measurements for each of a set of reference UEs, or a location of each of the set of reference UEs via an ML model, where the UE and the set of reference UEs include at least one common cell.Type: ApplicationFiled: September 14, 2022Publication date: March 14, 2024Inventors: Sooryanarayanan GOPALAKRISHNAN, Jay Kumar SUNDARARAJAN, Taesang YOO, Naga BHUSHAN, Guttorm Ringstad OPSHAUG, Grant MARSHALL, Chandrakant MEHTA, Zongjun QI

Patent number: 11873243Abstract: A method for inhibiting silica scale formation which treats aqueous systems containing silica with a bottle brush polymer. The bottle brush polymer includes a repeat unit obtained after polymerization of one or more anionic monomers, and a repeat unit obtained after polymerization of one or more polyoxoalkylene-containing monomers. The bottle brush polymer may further include a repeat unit obtained after polymerization of one or more nonionic monomers. The addition of the bottle brush polymer to the aqueous system results in the inhibition of silica scale.Type: GrantFiled: May 29, 2019Date of Patent: January 16, 2024Assignees: DOW GLOBAL TECHNOLOGIES LLC, ROHM AND HAAS COMPANYInventors: Puspendu Deo, Graham P. Abramo, Kaylie L. Young, Somil Chandrakant Mehta

Publication number: 20230350925Abstract: Implementations relate to systems and methods for aggregating and presenting data related to geographic locations. Geotag data related to geographic locations and associated features or attributes can be collected to build a regional profile characterizing a set of locations within the region. Geotag data related to the constituent locations, such as user ratings or popularity ranks for restaurants, shops, parks, or other features, sites, or attractions, can be combined to generate a profile of characteristics of locations in the region. The platform can generate recommendations of locations to transmit to the user of a mobile device, based for instance on the location of the device in the region as reported by GPS or other location service and the regional profile. Geotag data can include audio data analyzed using region-specific terms, and user recommendations can be presented via dynamic menus based on regional profiles, user preferences or other criteria.Type: ApplicationFiled: June 8, 2023Publication date: November 2, 2023Inventors: Mark BOYNS, Chandrakant MEHTA, Jeffrey TSAY, Giridhar Dhati MANDYAM

Publication number: 20220237631Abstract: Implementations relate to systems and methods for generating a user profile based on periodic location fixes. A cellular telephone or other mobile device captures location information via GPS or other capability. A location history can be generated from accumulated location fixes. The location history is then analyzed to detect the user's travel and dwell patterns. That information can be combined with business classification (e.g., SIC, etc.) or Point of Interest (POI) databases to identify a user's likely home, work, or other locations based on dwell-times, time of day, and other parameters. The user's age and gender can potentially be inferred based on types of locations visited, such as school locations. The user profile can be correlated with market segmentation databases to generate a marketing rating, such as a Nielsen or Claritas rating. Advertising, media, or other content can then be tailored to the user's individual location and demographic profiles.Type: ApplicationFiled: April 19, 2022Publication date: July 28, 2022Inventors: Chandrakant MEHTA, Robert LEWIS

Patent number: 9888360Abstract: Embodiments may automatically place access points (APs) on floor plans by incorporating a number of conventions for identifying types and locations of APs. These conventions may include the name of APs, MAC addresses, lat/lon information, and feature analysis or image recognition techniques for matching visual cues if the AP locations are marked on images. Some embodiment may conduct several other operations to optimize placement of APs. These optimization operations may reduce the number of steps needed to place APs on floor plans, and/or may reduce extraneous and superfluous information from the floor plans that may clutter the annotated floor plan map.Type: GrantFiled: February 8, 2013Date of Patent: February 6, 2018Assignee: QUALCOMM IncorporatedInventors: Abhinav Sharma, Sunil Patel, Murthy S.

Publication number: 20170367066Abstract: Techniques disclosed herein are generally directed toward providing customized location database information regarding terrestrial transceivers to a mobile device (e.g., a semi-connected mobile device) by causing the mobile device to scan for terrestrial transceivers during a first period of time, provide a list of the terrestrial transceivers detected during the first period of time to a location server, and receive location information for terrestrial transceivers on the list. Using this location information, the mobile device can subsequently (e.g., during a second period of time) calculate its position when the terrestrial transceivers are detected.Type: ApplicationFiled: December 30, 2016Publication date: December 21, 2017Inventors: Ashok Bhatia, Neethu Joseph, Wei Chen, Meghna Agrawal, Chandrakant Mehta
