  • Publication number: 20090094250
    Abstract: An improved system is disclosed for ensuring the integrity of data stored on a dispersed data storage network. Checksums are used to ensure integrity of both data segments and data slices. Checksums appended to data slices are checked by receiving slice servers to ensure that no errors occurred during transmission. Slice servers also periodically recalculate checksums for stored data slices to ensure that data slices have not been corrupted during storage. Checksums appended to data segments are checked when data segments are read from the storage network.

  • Publication number: 20090094320
    Abstract: A file system interface to a dispersed data storage network is disclosed. The disclosed interface accepts read and write commands from a file system resident on a user's computer and generates network commands that are forwarded to slice servers that form the storage component of the dispersed data storage network. The slice servers then fulfill the read and write commands.

  • Publication number: 20080183975
    Abstract: A rebuilder application operates on a dispersed data storage grid and rebuilds stored data segments that have been compromised in some manner. The rebuilder application actively scans for compromised data segments, and is also notified during partially failed writes to the dispersed data storage network, and during reads from the dispersed data storage network when a data slice is detected that is compromised. Records are created for compromised data segments, and put into a rebuild list, which the rebuilder application processes.

  • Patent number: 7398716
    Abstract: When a tube is to be cut into a plurality of sections, a tube feed assembly is operated to rotate the tube and to move the tube along its longitudinal central axis into a work station. The tube and a mandrel move into a telescopic relationship at the work station. The tube feed assembly presses an end of the tube against a stop surface on a stripper at the work station. A plurality of knives are moved into engagement with the tube to cut the tube. Relative movement between the stripper and mandrel separates the sections of the tube from the mandrel. A scrap end section of the tube is directed to a scrap receiving location. Other sections of the tube are directed to a product receiving location.

  • Patent number: 7327633
    Abstract: This invention relates in general to vibroseis and, more specifically, but not by way of limitation, to the enhancement and/or signal strength optimization of low frequency content of seismic signals for use in surveying boreholes and/or subsurface earth formations. In embodiments of the present invention, physical properties of a seismic vibrator may be analyzed and used to provide for determination of a driving force necessary to drive a reaction mass to produce a sweep signal with enhanced low frequency content for injection into the ground for vibroseis. In certain aspects, the physical properties may be considered independent of any geophysical properties related to operation of the seismic vibrator.

  • Publication number: 20070195644
    Abstract: Methods and systems for efficient compaction sweep and seismic data sweep are disclosed. One method comprises sweeping the source through a range of source frequencies for one or more compaction sweeps, each compaction sweep comprising a compaction sweep amplitude-frequency-time relationship; sweeping the source through a range of source frequencies for one or more data sweeps, each data sweep comprising a data sweep amplitude-frequency-time relationship; and correlating seismic responses only with the data sweeps. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

  • Patent number: 7123605
    Abstract: A method and system for reassignment of packet-pipes at a telecommunications switch. Upon detection of an increase in capacity of a packet-pipe (originating from a cell-site, for instance) and determination that the increase would overload a handler-module at the switch, a processor may analytically identify one or more packet-pipe reassignments that should be made at the switch so as to accommodate the increase in capacity. The processor may do so by successively considering the viability and impact of various possible reassignments. And the processor may produce an output report that indicates the reassignment(s) to make in order to accommodate the increase in capacity.
