Publication number: 20250106588Abstract: Example embodiments are directed to systems and methods for generating and providing elevation-aware hotspots. In example embodiments, a network system detects an initiation of a request for a transportation service at a client device of a user and receives an indication of a location of the client device and corresponding signal strengths associated with the client device. The network system then determines a telematics vector based on the signal strengths associated with the client device. Based on the location of the client device and the telematics vector associated with the client device, the network system identifies one or more top ranked elevation-aware hotspots. A pickup point recommendation is then presented, by the network system on a user interface on the client device of the user, whereby the pickup point recommendation includes the one or more top ranked elevation-aware hotspots.Type: ApplicationFiled: December 6, 2024Publication date: March 27, 2025Inventors: Michael Charles Albada, Vivek Sankaravadivel, Saebra Lynn Waterstraut

Publication number: 20230273326Abstract: A network system, such as a transport management system, infers movement and a location of a vehicle associated with a transportation service using sensor data from a provider client device and a wireless device mounted in a fixed position in the vehicle. Before or during a transportation service, the provider client device transmits sensor data to the network system for use in detecting the occurrence of one or more specified events, such as a sudden deceleration or a harsh turn. The network system fuses the received sensor data to infer the movement of the vehicle along forward, lateral, and vertical axes and implements an event detector by analyzing movement of the vehicle in the forward direction. Fused sensor data received from the wireless device is used to validate the detected movement and to determine a position of the vehicle.Type: ApplicationFiled: May 9, 2023Publication date: August 31, 2023Inventors: Andrew Irish, Dinesh Ramasamy, Andrew Joseph Beinstein, Theodore Russell Sumers, Hemabh Shekar, Vivek Sankaravadivel

Publication number: 20220326015Abstract: Aspects of the disclosure relate to initializing an inertial navigation system (INS) of a mobile device. Accelerometer bias of a plurality of accelerometers of the mobile device, and gyroscope bias of a plurality of gyroscopes of the mobile device, are determined. A first spatial relationship between a first frame of reference of the mobile device and a second frame of reference of a vehicle transporting the mobile device is determined. A second spatial relationship between the first frame of reference and a third frame of reference of a surface beneath the vehicle is determined. Each of the frames of reference are determined based on output of at least two of the GNSS receiver, the plurality of accelerometers, or the plurality of gyroscopes. The INS is provided with the accelerometer bias, the gyroscope bias, the first spatial relationship, and the second spatial relationship to initialize the INS.Type: ApplicationFiled: June 28, 2022Publication date: October 13, 2022Inventors: Vinod Kumar SAINI, Abdelmonaem LAKHZOURI, Bo ZHENG, William MORRISON, Vivek SANKARAVADIVEL

Publication number: 20210398041Abstract: A coordination server receives a request from a client device of a rider for transportation from a first location. The coordination server identifies a frequent spot based on the first location. The frequent spot is associated with a particular location and represents a plurality of historic first locations within a threshold distance from the frequent spot. The coordination server identifies a closest road segment with respect to the frequent spot. The closest road segment is a road segment of a plurality of road segments of an electronic map representing a geographic area around the first location. The coordination server determines a pickup side of the closest road segment based on the first location and the closest road segment. The coordination server sends, to a client device of a driver, a route to the first location such that the driver arrives on the pickup side of the closest road segment.Type: ApplicationFiled: June 21, 2021Publication date: December 23, 2021Inventors: Shivendra Pratap Singh, Krishna Aditya Gabbita, Yuxing Zhang, Konstantin Stulov, Pranav Deepak Agrawal, Vivek Sankaravadivel, Saandeep Depatla, Zehao Hu, Wenqi Hu, Andrew Irish, Anand Karthik Tumuluru, Henri Lapierre, Pranit Arora
