摘要： Embodiments apply user-specific usage patterns to estimate and preserve remaining battery life on a computing device. An amount of battery drain and an execution context are determined and stored for a plurality of recurring time periods. The execution context identifies operations executed by the computing device, signal strength, and other data describing the associated time period. If one of the operations is expected to be executed during a recurrence of at least one of the time periods, the expected execution is adjusted based on execution context and an estimated remaining battery life for the computing device. For example, the computing device may postpone or reschedule the operation for a time period during which the operation is expected to have a greater likelihood of completing successfully. In some embodiments, the battery preservation operations are automatically enabled at a particular threshold.

摘要： The present invention is directed to a system and method for monitoring system performance by sampling instructions in a burst mode, rather than once per interrupt. A burst mode may be configurable for a number of instructions per burst. Furthermore, these instructions are counted using a dynamic tree structure, rather than a log, which results in substantial savings in storage. The present invention requires minimal changes to the operating system, and no changes to application code that is being monitored. No recompilation is necessary to use the present invention. In addition, the present invention provides a system and method for monitoring code segments that are disabled for interrupts, and thus are difficult, if not impossible, to monitor using prior art performance tools. In a multi-processor system, the burst mode is active on all processors at the same time, and each processor has its own dynamic tree structure.

摘要： Various technologies described herein pertain to transferring geospatial tiles for Wi-Fi networks. A geospatial tile specifies a geographic region and includes data pertaining to a plurality of Wi-Fi networks having respective geographic coverage areas within the geographic region. A mobile device can receive an indicator that corresponds to a geospatial tile for retrieval by the mobile device. Further, the mobile device can request the geospatial tile from a tile management system based upon the indicator. Upon receiving the geospatial tile from the tile management system, the mobile device stores the geospatial tile in a tile cache. Further, the mobile device can automatically connect to a particular Wi-Fi network from the plurality of Wi-Fi networks utilizing data for the particular Wi-Fi network included in the geospatial tile when the mobile device is positioned within a geographic coverage area of the particular Wi-Fi network.

摘要翻译：本发明涉及一种用于通过以突发模式采样指令而不是每次中断一次来监视系统性能的系统和方法。可以针对每个突发的多个指令来配置突发模式。此外，这些指令使用动态树结构进行计数，而不是日志，从而大大节省存储空间。本发明需要对操作系统的最小的改变，并且不改变正被监视的应用程序代码。不需要重新编译来使用本发明。此外，本发明提供了一种用于监视对于中断被禁用的代码段的系统和方法，并且因此难以（如果不是不可能）使用现有技术的性能工具进行监视。在多处理器系统中，突发模式在所有处理器上同时处于活动状态，每个处理器都有自己的动态树结构。

摘要： The present invention is directed to a system and method for monitoring performance in an information handling system in a minimally intrusive manner. The method of the present invention includes a collection phase, a placement phase, and an instrumentation phase. During the collection phase, a workload (i.e. code segment) is traced, and instruction and data accesses are determined. During the placement phase, the trace data is passed to a cache simulator. The cache simulator uses the trace data, along with hardware and instrumentation characteristics, to determine an optimal placement for instrumentation code and data. If the desired conflict level is not attainable, the best possible placement is found by executing the code to be monitored with a variety of instrumentation code and data placements until the least intrusive placement is found. The best possible placement is then used during the instrumentation phase to actually execute the instrumented code.

摘要： The present invention is directed to a system and method for monitoring system performance by using a multi-phase approach. The first phase, referred to as the burst counting phase, utilizes a set of counters to identify calls and returns which are heavily used. In the second phase, referred to as the instrumentation phase, the performance characteristics of the "hot spots" are monitored through the use of hardware counters. In a symmetrical multi-processor embodiment, the performance profiler is active on all processors at the same time. Frequently executed code paths are identified in a manner that is minimally-intrusive to the system as a whole, and uses relatively little storage. The user may specify a threshold count, after which hardware monitoring begins, and the user may specify the type of hardware performance data collected. After both phases of the performance monitor are run, the data can be presented to the user in a variety of ways.

摘要： A method of indexing memory addresses associated with objects in a program file. In the prior art, a file has a single fixup record section which contains information necessary to determine memory addresses once the file is loaded onto the computer system. In the present invention, the fixup records are located within pages defined in the program file (e.g., data or text pages), and the fixup records are chained, that is, a given fixup record is based on a previous fixup record. In this manner, the overall size of the file is significantly reduced by reducing the collective size of all of the fixup records.
