  • Patent number: 9218740
    Abstract: Described is a technology by which driver safety technology such as collision detection is implemented via mobile device (e.g., smartphone) sensors and a cloud service that processes data received from vehicles associated with the devices. Trajectory-related data is received at the cloud service and used to predict collisions between vehicles and/or lane departures of vehicles. To operate the service in real-time with low latency, also described is dividing driving areas into grids, e.g., based upon traffic density, having parallel grid servers each responsible for only vehicles in or approaching its own grid, and other parallel/distributed mechanisms of the cloud service.

  • Patent number: 8665819
    Abstract: A method is provided in one example embodiment and includes providing an Internet Protocol (IP) address based on an authentication request associated with a device, the authentication request being associated with a Wi-Fi protocol. The method also includes identifying a Wi-Fi event associated with the IP address, and mapping the Wi-Fi event to a WiMax event. Further, the method includes providing a WiMax message, which is based on the Wi-Fi event, to a network element. In other embodiments, the mapping further includes converting the Wi-Fi event to the WiMax message such that the WiMax message is presented to the network element in a WiMax format. The same IP address can be used for both the Wi-Fi event and the WiMax message.

  • Publication number: 20120322497
    Abstract: One or more techniques and/or systems are disclosed for predicting when a signal handoff may occur from a current base station to a neighboring base station for a mobile device. An indication of signal strength between the mobile device and the current base station and an indication of signal strength between the mobile device and a (e.g., closest) neighboring base station can be monitored by the mobile device. A difference between these signal strength indications can be determined and compared against a threshold (e.g., based upon historical signal handoffs) to predict when and/or where a signal handoff may occur. The predicted signal handoff may be determined by the mobile device and a corresponding notification can be provided so that appropriate action may be taken (e.g., a user may not initiate a call and/or an application may not attempt to communicate data).

  • Publication number: 20110304503
    Abstract: The simultaneous localization and RF modeling technique pertains to a method of providing simultaneous localization and radio frequency (RF) modeling. In one embodiment, the technique operates in a space with wireless local area network coverage (or other RF transmitters). Users carrying Wi-Fi-enabled devices traverse this space while the mobile devices record the Received Signal Strength (RSS) measurements corresponding to access points (APs) in view at various unknown locations and report these RSS measurements, as well as nay other available location fix to a localization server. A RF modeling algorithm runs on the server and is used to estimate the location of the APs using the recorded RSSI measurements and any other available location information. All of the observations are constrained by the physics of wireless propagation. The technique models these constraints and uses a genetic algorithm to solve them, thereby providing an absolute location of the mobile device.
