20100050015 | TRIPLE PARITY TECHNIQUE FOR ENABLING EFFICIENT RECOVERY FROM TRIPLE FAILURES IN A STORAGE ARRAY - A method for recovering from three failed data storage devices is disclosed. A plurality of data storage devices hold data, and a row parity storage device holds row parity for them. The data storage devices and the row parity storage device form a set of storage devices. A diagonal parity storage device and an anti-diagonal parity storage device hold parity computed diagonally over the set of storage devices. In the event of a failure of three data storage devices of the set of storage devices, a first failed storage device is chosen for first restoration. A missing block of the first failed storage device is computed by using the remaining set of storage devices, and the diagonal parity storage device, and the anti-diagonal parity storage device. The remaining two failed storage devices are restored by a diagonal parity restoration technique. | 02-25-2010 |
20110010599 | N-WAY PARITY TECHNIQUE FOR ENABLING RECOVERY FROM UP TO N STORAGE DEVICE FAILURES - An n-way parity protection technique enables recovery of up to n storage device (e.g., disk) failures in a parity group of a storage array encoded to protect against n-way disk failures. The storage array is created by first configuring the array with m data disks, where m=p−1 and p is a prime number and a row parity disk. n−1 diagonal parity disks are then added to the array. Each diagonal parity set (i.e., diagonal) is associated with a slope that defines the data and row parity blocks of the array that are included in the diagonal. All diagonals having a common slope within a parity group are organized as a diagonal parity class. For each diagonal parity class, a diagonal parity storage disk is provided to store the diagonal parity. | 01-13-2011 |
20120324284 | TRIPLE PARITY TECHNIQUE FOR ENABLING EFFICIENT RECOVERY FROM TRIPLE FAILURES IN A STORAGE ARRAY - A triple parity (TP) technique reduces overhead of computing diagonal and anti-diagonal parity for a storage array adapted to enable efficient recovery from the concurrent failure of three storage devices in the array. The diagonal parity is computed along diagonal parity sets that collectively span all data disks and a row parity disk of the array. The parity for all of the diagonal parity sets except one is stored on the diagonal parity disk. Similarly, the anti-diagonal parity is computed along anti-diagonal parity sets that collectively span all data disks and a row parity disk of the array. The parity for all of the anti-diagonal parity sets except one is stored on the anti-diagonal parity disk. The TP technique provides a uniform stripe depth and an optimal amount of parity information. | 12-20-2012 |

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 |
