Method and apparatus for application of power density multipliers optimally in a multicore system
A method and an apparatus are described that delay application of a higher order Power Density Multiplier (PDM) using a time based moving average of a number of active cores in a multicore system. A PDM is applied to a thermal design power budget of a thermal entity and performance of the thermal entity is increased by transferring available power from a thermal entity not in an active state to a thermal entity in an active state. Sufficient time is allowed for the cooling effect of reduced active cores, to influence the active core that receives the extra power (a higher PDM). Similarly delaying application of a lower PDM with the same moving average, but a different threshold, allows a core to retain a higher power allocation until the more active neighbor core(s) cause it to heat up, thereby boosting core performance. |

Interfaces for digital media processing
APIs discussed herein promote efficient and timely interoperability between hardware and software components within the media processing pipelines of media content players. A PhysMemDataStructure API facilitates a hardware component's direct access to information within a memory used by a software component, to enable the hardware component to use direct memory access techniques to obtain the contents of the memory, instead of using processor cycles to execute copy commands. The PhysMemDataStructure API exposes one or more fields of data structures associated with units of media content stored in a memory used by a software component, and the exposed fields store information about the physical properties of the memory locations of the units of media content. SyncHelper APIs are used for obtaining information from, and passing information to, hardware components, which information is used to adjust the hardware components' timing for preparing media samples of synchronously-presentable media content streams. |

Method and system for transferring repetitive images over computer networks
A method and system is provided for enhancing a reproduction of a recurring image of an first computer on a second computer in a computer network. In order to avoid transferring high color depth high volume of data for recurring images on one computer to another, the recurring image is invoked by a low bit identifier.

Active noise injection computations for improved predictability in oil and gas reservoir discovery and characterization
Application of nonlinear resonance interferometry is introduced as a new geophysical approach to improve predictability in characterization of subsurface porosity, rock and fluid properties. In contrast to reflection methods that remove random information noise, nonlinear resonance interferometry exploits the full seismic acquisition spectrum to assess how low frequency and high-frequency noise is differentially and directly modulated by varying levels of porosity and hydrocarbon content in the lithologies of interest. In some examples, systems and techniques implement novel computational interactions between acquired seismic wavefield attributes and a nonlinear system in software to amplify distortions in seismic noise and exploits injection of synthetic noise, in software format, to detect hydrocarbon traps and lithology changes at spatial scales below seismic resolution, thereby increasing the information value of low-resolution data. The techniques are broadly applicable to de-risking conventional clastic and carbonate reservoirs and non-conventional shale gas resource prospects. |

Inspection apparatus and inspection method
The invention is directed to find a false defect from defect candidates and obtain a threshold with which the false defect can be eliminated by the smallest number of review times. Defect candidates are reviewed and selected as a defect or a false defect. By deleting a defect candidate having a characteristic quantity equal to or less than that of the false defect from a map or displaying it in another sign, the false defect can be determined visually. Since the defect candidate having the characteristic quantity equal to or less than that of the selected false defect is deleted from the map or displayed in another sign, the defect candidates unnecessary to set a threshold are not reviewed. The number of defect candidates to be reviewed can be largely reduced as compared with that in the conventional technique. Further, by repeating the above work, the threshold is automatically calculated, and an inspection result map with the threshold is displayed, so that a re-inspection is unnecessary. |
