Patents

  1. U.S. Patent # 10,121,212 – System and Method for Transportation Demand Mangement – A location-aware system that collects travel behavior information from a mobile device and provides personalized suggestions for optimizing travel behavior. Issued Nov 6, 2018, U.S. Patent and Trademark Office.
  2. U.S. Patent # 9,130,995 – System and Method for Rendering a Distributed Location-Aware System – A distributed location-aware system that is able to efficiently exchange location data over large geographic areas without requiring a centralized server. Issued Sept 8, 2015, U.S. Patent and Trademark Office.
  3. U.S. Patent # 9,047,384 – System and Method for Automatically Determining Purpose Information for Travel Behavior – A method to derive trip purpose information from GPS data from a mobile device using Geographic Information System (GIS) data for land use categories and user-provided information for home and work locations. Issued June 2, 2015, U.S. Patent and Trademark Office.
  4. U.S. Patent # 8,924,536 – Distributed and Decentralized Location Aware Architecture – A distributed and decentralized location-aware system that includes a number of peers, each in communication with other peers and adapted to communicate PING, PONG, and ALERT messages. Each of the messages has a header that includes location information. Issued December 30, 2014, U.S. Patent and Trademark Office.
  5. U.S. Patent # 8,843,315 – System and Method for Spatial Point-of-Interest Generation and Automated Trip Segmentation Using Location Data – An algorithm that creates points-of-interests (e.g., Home, Work) from raw tracking data (e.g., GPS).  These points-of-interest are then used to segment the raw tracking data into discrete trips from one location to another.  The amount of time that the user spends at a particular point-of-interest, and when they arrive at and depart from each point-of-interest is also calculated.  Issued September 23, 2014, U.S. Patent and Trademark Office.
  6. U.S. Patent # 8,751,162 – System for Pattern Recognition in Real-time Location-based Services Applications – A prediction method that estimates the real-time position of a mobile device based on previously observed data is provided. The present invention can be used in real-time navigation, including providing real-time alerts of an upcoming destination and notifications of emergency events in close geographic proximity. The prediction method utilizes neural networks and/or functions generated using genetic algorithms in estimating the mobile device’s real-time position. The prediction method provides reliable Location-Based Services (LBS) in events where traditional positioning technologies become unreliable. It is also seamless, as the user remains unaware of any interruption in accessing the positioning technology.  Issued June 10, 2014, U.S. Patent and Trademark Office.
  7. U.S. Patent # 8,725,831 – Architecture and Two-Layered Protocol for Real-Time Location-Aware Applications – Defines an architecture and a two-layer communication protocol that provides timely location updates via an unreliable protocol, and also provides a subscription mechanism that allows a location-aware application on a mobile device to act not only on its own real-time location, but also on the real-time location of other mobile devices in the system. Issued May 13, 2014, U.S. Patent and Trademark Office.
  8. U.S. Patent # 8,718,671 – Adaptive Location Data Buffering for Location-Aware Applications – Supports the use of an unreliable protocol (e.g., UDP) to transmit location data from a mobile device to a server in real-time, while occasionally checking if a connection with the server exists using a reliable protocol (e.g., TCP).  If a reliable connection fails, location data is buffered on the device until the next successful reliable connection.  This allows energy and data-efficient communication of real-time tracking information, while still providing some measure of reliability.  Issued May 6, 2014, U.S. Patent and Trademark Office.
  9. U.S. Patent # 8,600,674 – Using Pattern Recognition in Real-time LBS Applications – Estimates the position of a mobile device based on previously observed (i.e., historical) data, when real-time positioning data such as GPS is unavailable.  Issued December 3, 2013, U.S. Patent and Trademark Office.
  10. U.S. Patent # 8,548,724 – System and Method for Real-time Travel Path Prediction and Automated Incident Alerts – Predicts an individual’s travel path, based on their real-time location and personal travel history, and delivers highly-targeted incident alerts based on this information.  Issued October 1, 2013, U.S. Patent and Trademark Office.
  11. U.S. Patent # 8,249,807 – Method for Determining Critical Points in Location Data Generated by Location-Based Applications – Reduces the amount of location data sent over a wireless network by pre-filtering the data on-board a mobile device and eliminating “non-critical” points that aren’t needed to recreate the device’s path.  Reduced data transmissions result in reduced battery energy consumption and reduced data costs.  Issued August 21, 2012, U.S. Patent and Trademark Office.
  12. U.S. Patent # 8,169,342 – Method of Providing a Destination Alert to a Transit System Rider – Algorithm used in the Travel Assistance Device (TAD) system to alert a transit rider when to exit the bus based on their real-time location and nearby bus stops.  Issued May 1, 2012, U.S. Patent and Trademark Office.
  13. U.S. Patent # 8,145,183 – On-Demand Emergency Notification System using GPS-equipped Devices – Mobile app to automatically determine the cell phone user’s current evacuation zone and real-time evacuation information for that zone.  Issued March 27, 2012, U.S. Patent and Trademark Office.
  14. U.S. Patent # 8,138,907 – Travel Assistant Device – Travel Assistance Device (TAD) system to assist transit riders with intellectual disabilities.  Issued March 20, 2012, U.S. Patent and Trademark Office.
  15. U.S. Patent #8,140,256 – Dynamic Ridematching Algorithm.  – GIS-based Algorithm to match riders for carpools that are traveling on similar routes.  Issued March 20, 2012, U.S. Patent and Trademark Office.
  16. U.S. Patent # 8,045,954 – Wireless Emergency-Reporting System – Bidirectional location-based multimedia messaging system.  Issued October 25, 2011, U.S. Patent and Trademark Office.
  17. U.S. Patent # 8,036,679 – Optimizing performance of location-aware applications using state machines – Dynamically adjusts GPS sampling rates to allow high resolution tracking while moving and conservation of battery energy when  stopped.  Issued October 11, 2011, U.S. Patent and Trademark Office.
