  • Patent number: 8997245
    Abstract: Systems and techniques for managing software licensing are described. When a computing system service request is made, the request is intercepted and software information that may be more or less continuously updated in a managed computing environment is examined to determine the effect of the service request on software usage by the system. The software usage represented by the service request is evaluated based on licensing information to determine license usage by the system and changes in license usage based on the service request, and license usage information is determined based on the software usage and the licensing information. The license usage information may be used in connection with a system of rules to govern actions such as reporting licensing usage or allowing or preventing the use of software based on whether use of the software will violate licensing requirements.

  • Patent number: 8995417
    Abstract: Techniques to increase capacity in a wireless communications system. In an aspect, systematic non-transmission, or “blanking,” of minimal-rate frames transmitted in a communications system is provided. In an exemplary embodiment, eighth rate frames in a cdma2000 voice communications system are systematically substituted with null-rate frames carrying zero traffic bits. Provisions are nevertheless made for the transmission of certain designated as “critical” by, e.g., a vocoder. The receiver detects the presence of null rate or non-null rate transmissions and processes the received frames accordingly, including updating an outer loop power control only in response to non-null rate frames. Further techniques for changing the pilot transmission gating pattern to assist the receiver in detecting null rate frames are provided. In another aspect, early termination of a signal transmission over a wireless communications link is provided.

  • Patent number: 8997071
    Abstract: A compiler implemented by a computer performs optimized division of work across heterogeneous processors. The compiler divides source code into code sections and characterizes each of the code sections based on pre-defined criteria. Each of the code sections is characterized as at least one of: allocate to a main processor, allocate to a processing element, allocate to one of a parameterized main processor and a parameterized processing element, and indeterminate. The compiler analyzes side-effects and costs of executing the code sections on allocated processors, and transforms the code sections based on results of the analyzing. The transforming includes re-characterizing the code sections for alternate execution in a runtime environment.
