20100235396 | Distributed File System Access - A system and method for providing access in a distributed filesystem. The disclosure describes systems and methods for providing access to filesystem objects in a distributed filesystem (DFS). In one implementation, access to filesystem objects in the DFS can he restricted to only authenticated users and client devices. To this end, the client devices of the DFS can be divided into trusted and non-trusted clients, and further access can be denied to non-trusted clients. Concepts of trusted computing can be utilized to obtain trusted clients. New clients added to the system can be added as non-trusted clients. Further, access can be restricted by extending the file access permissions to include additional bits that can control access to non-trusted clients. In certain situations, the owner of the object can be allowed access to the object from a non-trusted client. | 09-16-2010 |

20150293847 | METHOD AND APPARATUS FOR LOWERING BANDWIDTH AND POWER IN A CACHE USING READ WITH INVALIDATE - Ephemeral data stored in a cache is read when needed but is not written to system memory so as to save power and bandwidth. In an embodiment, a no-writeback bit associated with the ephemeral data is set in response to a read-no-writeback instruction. Data in a cache line for which its no-writeback bit has been set is not written back into system memory. Accordingly, when evicting cache lines, if a cache line has a no-writeback bit set, then the data in that cache line is discarded without being written back to system memory. | 10-15-2015 |
20150302903 | SYSTEM AND METHOD FOR DEEP COALESCING MEMORY MANAGEMENT IN A PORTABLE COMPUTING DEVICE - Various embodiments of methods and systems for deep coalescing memory management (“DCMM”) in a portable computing device (“PCD”) are disclosed. Because multiple active multimedia (“MM”) clients running on the PCD may generate a random stream of mixed read and write requests associated with data stored at non-contiguous addresses in a double data rate (“DDR”) memory component, DCMM solutions triage the requests into dedicated deep coalescing (“DC”) cache buffers, sequentially ordering the requests and/or the DC buffers based on associated addresses for the data in the DDR, to optimize read and write transactions from and to the DDR memory component in blocks of contiguous data addresses. | 10-22-2015 |

20130142249 | METHOD AND APPARATUS FOR PERFORMING VIDEO AND IMAGE COMPRESSION USING A VIDEO ENCODER - A video encoding method and a video encoder are described for processing frames in a group of pictures (GOP). A difference between a bit budget of a selected frame in the GOP and an estimated number of bits consumed by the selected frame is determined. Quantization parameter (Qp) values assigned to coefficients of macroblocks (MBs) in the selected frame are adjusted if the difference does not fall within a tolerance. The Qp values may be filtered. A bit budget to the GOP may be assigned or adjusted based on a target bitrate. A bit budget may be assigned to each unprocessed frame in the GOP. Spatial activity may be calculated for each MB in the selected frame, and a bit budget and quantization may be assigned for each MB in the selected frame based on the spatial activity. | 06-06-2013 |

20090282224 | CLIPPING A KNOWN RANGE OF INTEGER VALUES USING DESIRED CEILING AND FLOOR VALUES - An aspect of the present invention clips a sequence of data values within a known range (defined by a set of integer values) by a ceiling value and a floor value. In an embodiment, such a feature is obtained by first storing in each of a sequence of memory locations a respective value corresponding to each integer value, with a stored value in a memory location equaling the floor value if the memory location corresponds to an integer having a value less than the floor value, equaling the ceiling value if the memory location corresponds to an integer having a value greater than the ceiling value, and equaling the value of the corresponding integer otherwise. When a sequence of data values are thereafter received for clipping, the clipped value for each data value is obtained by merely retrieving a corresponding stored value from the corresponding location. | 11-12-2009 |
20090303338 | DETAILED DISPLAY OF PORTION OF INTEREST OF AREAS REPRESENTED BY IMAGE FRAMES OF A VIDEO SIGNAL - According to an aspect of the present invention, a sequence of combined frames are formed by including each of a sequence of source image frames and a portion of the same source image frame in the corresponding combined frame. The combined image frames may be displayed on a display screen. The display screen can also be used to display the sequence of source image frames alone (instead of the combined image frames), at user's option. | 12-10-2009 |

20110210315 | NOVEL DONOR-ACCEPTOR FLUORENE SCAFFOLDS: A PROCESS AND USES THEREOF - The present invention relates to novel donor-acceptor fluorene compounds, which can be used as for the fabrication of electroluminescent devices, and a process of preparing said novel compounds. More particularly, the present invention relates to amine donor and nitrile/ester acceptor fluorenes, fluorenones their π-conjugated systems and related compounds, processes for preparing the said compounds including oxidation of fluorenes to corresponding fluorenones and their use in preparing organic electronic devices such as organic light emitting diodes (OLEDs), photovoltaic/solar cell, Field effect transistors and other useful electroluminescent devices. The compounds are prepared by reacting 2H-pyran-2-ones in isolated or rigid conformations with cyclic ketones containing methylene carbonyl moiety in the presence of a base in an organic solvent. The present invention also relates to a new concept and approach to overcome the problem of ‘Green emission defect’ in 9-unsubstituted fluorene-based organic light emitting diodes which occurs due to the conversion of fluorenes to fluorenones that show emission mainly in green-yellow region. In the present invention we have placed donor-acceptor substituents in such a way that donor-acceptor fluorenones show emission in the blue region (instead of green-yellow region) thus improving the blue colour purity and overcoming the problem of green emission defect. | 09-01-2011 |
