  • Location determination
    Patent number: 8644843
    Abstract: Systems, methods, and computer program products obtain power information indicating a detected power of respective signals received in a mobile device from multiple transmitters. Using at least the obtained power information, respective probability values for a plurality of positions are determined, each probability value indicating a probability that the mobile device is in a corresponding position. An estimated position of the mobile device is identified based at least in part on the determined probability values.
    Type: Grant

  • Compiling techniques for providing limited accuracy and enhanced performance granularity
    Patent number: 8370822
    Abstract: A programmable compiler detects from source code invocations of math functions that require reduced levels of accuracy, limited variable domains, or enhanced performance. The programmable compiler replaces such invocations with intrinsics from the compiler's own intrinsic library. The math function invocations are compiled into inline object code. The inline object can be subsequently optimized along with other object code through normal compiler optimization. If an accuracy requirement is beyond what any compiler intrinsic can provide, the programmable compiler preserves the invocation of the math function defined in a default library.
