  • Publication number: 20100169284
    Abstract: In one embodiment the present invention includes a system for transaction recovery in a distributed computing environment. The system includes a transaction log server, application servers, and resource servers. The transaction log server stores a shared transaction log. The application servers implement a distributed transaction application and accesses the shared transaction log when performing a transaction using the distributed transaction application. The resource servers store data and that operate with the application servers to access the data according to the transaction. If one of the application servers fails, another application server assumes responsibility for a portion of the shared transaction log that was previously accessed by the failed application server.

  • Patent number: 7456784
    Abstract: A portable GPS/radio unit communicates over a wireless radio network with at least one other unit which is transmitting radio signals over the network indicative of that unit's location. The GPS/radio unit comprises a GPS receiver for receiving satellite signals from a plurality of satellites, a radio receiver for receiving the radio signals transmitted by the other unit, a processor for calculating the unit's location as a function of the received satellite signals and for identifying the location of the other unit based on the received radio signals, and a display for indicating the location of the other unit. The display may indicate the respective locations of multiple units and may also display unique identifiers for each of the units. A system and method for indicating the location of one portable GPS/radio unit on the display of another portable GPS/radio unit involves at least two such units communicating with one another over a wireless radio network.

  • Patent number: 7409288
    Abstract: Systems, devices and methods are provided for an improved navigational route planning device which provides more understandable, accurate and timely route calculation capabilities. The navigational aid device with route calculation capabilities includes a processor connected to a memory. The memory includes cartographic data and a desired destination, the cartographic data including data indicative of thoroughfares of a plurality of types. A display is connected to the processor and is capable of displaying the cartographic data. The device is adapted to calculate a route to navigate to the desired destination. And, the device is adapted to adjust a starting point for the route calculation to an appropriate location such that the device is on the route at a time when the route calculation is completed. The device processes travel along the route, recognizes when the device has deviated from the route, and calculates a new route to navigate to the desired destination.
