Abstract: The systems and methods for software application usage detection on a mobile device are disclosed. The software application usage detection is done by monitoring the network usage of the application. The software application usage information is further refined by monitoring the screen lock state of the mobile device. The screen lock information is used to refine the background and foreground usage of the software application.

Abstract: The display of a Windows Desktop is modified using one or more processors (e.g. CPUs and/or GPUs) that re-direct drawing of the Desktop to mirrored swap chain buffers; modify the contents of the a front buffer of the mirrored swap chain buffers; and draw the Desktop using the modified contents of the front buffer of the mirrored swap chain buffers. To modify the displayed Desktop, Windows needs to draw into these mirrored swap chains instead of its own. To accomplish this, all Direct3D functions that use a swap chain are hooked so that they return the mirrored swap chain, and any function that uses the contents of the swap chain are hooked. Basically any function that takes a Direct3D surface or texture is hooked and the respective item from the mirrored swap chains is returned if it is in the mirrored swap chain data structures.

Abstract: A number of cameras capture a scene and send corresponding video sub-streams to an acquisition PC. Each sub-stream is made up of a plurality of sub-frames. The acquisition PC sends the sub-streams over a network to a playback PC. The playback PC stores each sub-frame in a queue corresponding to an associated sub-stream. For each sub-stream the playback PC calculates a sub-stream average period to produce a plurality of sub-stream average periods. It then calculates a composite average period by averaging the plurality of sub-stream average periods, and calculates a playback frame rate as a reciprocal of the composite average period. The playback PC then reads the sub-frames from their corresponding queue in synchronism with the calculated playback frame rate to display the plurality of sub-streams.

Abstract: A best blending function from among a plurality of blending functions is determined. Each of the plurality of blending functions smoothes an overlap region of at least two projected images. The overlap image is captured and a processing unit analyzes the stored overlap image for color value linearity to calculate a first smoothness result. The processing unit analyzes the projection of the first or second image for color value uniformity to calculate a second smoothness result. These smoothness results for one blending function are paired and compared to smoothness result pairs corresponding to other blending functions to determine a best blending function from among those being analyzed.
