Patent number: 11709220Abstract: A network system uses Wi-Fi signals or other types of short-range transmissions to determine pickup locations for users receiving services provided via the network system. The network system builds a database of search records mapping pickup locations to signatures of short-range transmission detected by users' client devices when they searched for the pickup locations. By comparing a signature detected by a given user's client device to the signatures in the database, the network system can check for similarities between the short-range transmissions. Responsive to finding a match, the network system predicts that the given user is likely to select a similar pickup location as other users whose client devices detected the signatures corresponding to the match. Accordingly, by leveraging the database, the network system can predict pickup locations without requiring the given user to input a search for a pickup location.Type: GrantFiled: November 19, 2020Date of Patent: July 25, 2023Assignee: Uber Technologies, Inc.Inventors: Anson Chu, Brandon Iles, Dinesh Ramasamy, Juthika Kiran Dabholkar, Upamanyu Madhow, William J.

Patent number: 11443334Abstract: A network system, such as a transport management system, efficiently allocates resources by monitoring the geospatial and topological locations of a rider responsive to receiving a trip request. A trip management module matches a rider with an available driver based in part on an comparison of the estimated times of arrival of the rider and the driver at the pickup location. A client positioning module monitors the rider's progress through nodes and edges in a topological graph associated with the origin location based on radio signatures received at the rider client device. A client ETA module calculates a rider ETA based on the rider's rate of travel through the origin location represented by nodes in the topological graph. Responsive to determining that the rider ETA and the driver ETA vary by over a threshold amount of time, the trip management module matches the rider with a second available driver.Type: GrantFiled: September 28, 2020Date of Patent: September 13, 2022Assignee: Uber Technologies, Inc.Inventors: Upamanyu Madhow, Daniel Iland, Dinesh Ramasamy

Patent number: 10955561Abstract: A method of determining location of a user device includes receiving global navigation satellite system (GNSS) fix data that represents GNSS calculated position of the user device, receiving signal strength data associated with each satellite communicating with the user device, and receiving satellite data regarding locations of satellites. The method further includes retrieving satellite blocking values from a cache that describe a likelihood of a satellite signal being blocked at a plurality of possible locations. A non-linear filter, implemented by one or more processors, is applied to the GNSS fix data, signal strength data, and satellite blocking values to generate an updated position estimate of the user device.Type: GrantFiled: August 19, 2019Date of Patent: March 23, 2021Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Andrew Irish, Upamanyu Madhow
