Abstract: Systems and methods for providing accelerated data storage and retrieval utilizing lossless and/or lossy data compression and decompression. A data storage accelerator includes one or a plurality of high speed data compression encoders that are configured to simultaneously or sequentially losslessly or lossy compress data at a rate equivalent to or faster than the transmission rate of an input data stream. The compressed data is subsequently stored in a target memory or other storage device whose input data storage bandwidth is lower than the original input data stream bandwidth. Similarly, a data retrieval accelerator includes one or a plurality of high speed data decompression decoders that are configured to simultaneously or sequentially losslessly or lossy decompress data at a rate equivalent to or faster than the input data stream from the target memory or storage device. The decompressed data is then output at rate data that is greater than the output rate from the target memory or data storage device.

Abstract: Systems and methods for providing fast and efficient data compression using a combination of content independent data compression and content dependent data compression. In one aspect, a method for compressing data comprises the steps of: analyzing a data block of an input data stream to identify a data type of the data block, the input data stream comprising a plurality of disparate data types; performing content dependent data compression on the data block, if the data type of the data block is identified; performing content independent data compression on the data block, if the data type of the data block is not identified.

Abstract: A method for disseminating emergency notification content from an emergency originating source. The method comprising: delivering the emergency notification content from the emergency originating source to at least one transmitting party; selecting a subset of users from among a set of users for dissemination of the emergency notification content based on the subject matter of the emergency notification content; and delivering the emergency notification content from the at least one transmitting party to a device corresponding to each user from the selected subset of users.

Abstract: A fuel pumping apparatus, particularly useful for gas turbine engines, includes a dual element positive displacement fuel pump having a centrifugal type boost stage and, downstream, at least two parallel gear type elements. A controllable means for unlocking at least one of the elements includes a bypass line which provides a flow path to the inlet of the fuel pump from the pressurizing chamber of the gear elements which is used to urge end bearings of the gear elements into contact with the revolving gears thereby enabling the gears to pump fluid. Disposed in the bypass line is slide valve to open up the bypass line and unload and render the unloadable gear element inoperative. Control is provided by a Full Authority Digital Electronic Control and its associated Hydromechanical Unit which uses the fuel as a hydraulic fluid to actuate the slide valve.
