20100070171 | System and Method for Real-Time Travel Path Prediction and Automatic Incident Alerts - A path prediction method that uses a commuter's travel patterns to predict their route and destination, and transmit road advisories via a GPS-enabled device. Once the user's location data is transmitted via a GPS-enabled device it is then catalogued and stored in a GIS database. The user's current travel path is then compared to their path history and statistics and a destination is determined based on related spatial and time properties. A warning is then automatically delivered to the user if there is an accident along their predicted path, without requiring any request or input form the user. | 03-18-2010 |
20110246606 | ARCHITECTURE AND TWO-LAYERED PROTOCOL FOR REAL-TIME LOCATION-AWARE APPLICATIONS - A two-layer communication protocol that supports efficient real-time location-aware application on multiple mobile devices that must communicate with each other and/or a centralized server. The two-layer protocol includes a method of communicating data between a first mobile device and a second mobile device using a server to facilitate the communication of the data. The two-layer communication protocol also includes a method of communicating data between a first mobile device and a second mobile device using a server to facilitate the connection between the two devices. The communication of data occurs directly between the two mobile devices. Each method uses reliable, connection-oriented protocols to exchange application-level information and control signals while utilizing unreliable, connection-less protocols to communicate real-time location data. Also provided are architectures implementing these methods. | 10-06-2011 |
20110275384 | ADAPTIVE LOCATION DATA BUFFERING FOR LOCATION-AWARE APPLICATIONS - A method of buffering location data on a mobile device. The method transmits location data packets via an unreliable protocol to a receiving device and buffers a copy of the location data packet. Periodically, the method also transmits a location data packet via a reliable protocol to the receiving device. When no acknowledgement is received from the receiving device, the location data sent via the reliable protocol is buffered to memory. Once an acknowledgement is received from the receiving device, all of the buffered location data is sent to the receiving device via an unreliable protocol. | 11-10-2011 |
