Abstract: An aircraft store ejector systems and subsystems thereof. Embodiments can include a two-reservoir re-pressurization system wherein a remote reservoir is used to maintain desired pressure in a local ejector reservoir. The system can include a release valve having a vent valve and valve piston. The release valve can control release of pressurized gas to a pitch control valve. The pitch control valve can be configured to distribute the pressurized gas between two or more ejector piston assemblies. One or more of the ejector piston assemblies can include multiple concentric piston stages and piston chambers, the piston chambers configured to contain a volume of gas. The ejector piston assemblies can be configured to compress the volume of gas within the piston chambers as the piston stages are extended out from the aircraft. Such compression can provide a return force to the piston stages.

Abstract: A method of storing data received in a data stream from a data source is disclosed in which prior to performing deduplication on the data stream a processor decompresses selected compressed data entities in the data stream to provide a decompressed form of the data entities in the data stream in place of the compressed form, the data stream including the decompressed data entities is deduplicated and the deduplicated data is stored to a deduplicated data store.

Abstract: A method of controlling relative motion of a data storage medium on which data is stored in data groups comprising tracks extending across the storage medium and a rotatable transducer for reading data from the storage medium includes determining from the data groups a start reread data group at which a data reread process is to start following detection of a read error condition in a preceding data read process. The method also includes obtaining a reread track reference value for use in controlling that relative motion during the data reread process using a track reference value difference stored in at least one track of at least one data group that is to be reread during the data reread process and a track reference value that was used in controlling that relative rotation during the preceding data read process.
