| 20100023529 | METADATA MANAGEMENT SYSTEM FOR AN INFORMATION DISPERSED STORAGE SYSTEM - An apparatus includes a processing module and a network interface. The processing module is operably coupled to obtain; a data storage transaction request regarding a file; determine identity of a user based on the data storage transaction request; access file level metadata based on the identity of the user to determine a plurality of file slices associated with the file; access file slice metadata to identify at least one of a plurality of storage nodes that stores or is to store, a data slice and coded subsets of at least one of the plurality of file slices; and generate a data storage transaction message to facilitate a data storage transaction regarding the at least one of the plurality of file slices. The network interface is operably coupled to convert the data storage transaction message into a network data storage message and transmit it. | 01-28-2010 |
| 20100161916 | METHOD AND APPARATUS FOR REBUILDING DATA IN A DISPERSED DATA STORAGE NETWORK - A method begins by identifying a data slice requiring rebuilding to produce an identified data slice, wherein the identified data slice is one of a plurality of data slices that constitute a data segment and wherein each of the plurality of data slices is assigned for storage by a corresponding one of a plurality of data slice servers. The method continues by retrieving at least m number of data slices from at least m number of the plurality of data slice servers, wherein m data slices of the plurality of data slices enable reconstruction of the data segment, and wherein the at least m number of data slices does not include the identified data slice. The method continues by reconstructing the identified data slice from the at least m number of data slices to produce a rebuilt data slice. The method continues by writing the rebuilt data slice to the corresponding one of the plurality of data slice servers or to a new slice server. | 06-24-2010 |
| 20100306578 | RANGE BASED REBUILDER FOR USE WITH A DISPERSED DATA STORAGE NETWORK - A message is generated by a computer operating on a dispersed data storage network indicating the inaccessibility of a plurality of data slices. A rebuilder application operates on the dispersed data storage grid and rebuilds inaccessible data slices, including those identified by the message. | 12-02-2010 |
| 20110289283 | MEMORY DEVICE UTILIZATION IN A DISPERSED STORAGE NETWORK - A method begins by a processing module determining whether a memory device of a dispersed storage (DS) unit is unavailable to produce an unavailable memory device. The method continues with the processing module determining a methodology regarding DS encoded data stored in the unavailable memory device based on one or more dispersed storage network (DSN) conditions to produce a determined methodology when the memory device is unavailable. The method continues with the processing module initiating, in accordance with the determined methodology, a rebuilding function to rebuild the DS encoded data to produce rebuilt DS encoded data when the determined methodology includes a rebuilding component. The method continues with the processing module storing the rebuilt DS encoded data within available memory of the DS unit. | 11-24-2011 |

| 20090094250 | Ensuring data integrity on a dispersed storage grid - 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. | 04-09-2009 |
| 20100268806 | Systems, apparatus, and methods for utilizing a reachability set to manage a network upgrade - A method of upgrading software components within a dispersed data storage network is disclosed. A list of identifiers corresponding to devices within the dispersed data storage network is assembled. Each member of the list is assigned to an upgrade set based on the devices that are reachable by the vaults associated with the device. | 10-21-2010 |

| 20110314986 | PULL ROD RELEASE MECHANISM FOR A PUSH-PULL TABLE TOOL - In at least one embodiment, a table saw includes a table, a moveable carriage supported by the table, a saw assembly supported by the carriage, and a pull rod coupled to the carriage. The pull rod is configured to move in a linear direction relative to the housing between a back position and a forward position. The carriage and saw assembly move in the linear direction when the pull rod is moved in the linear direction. A collar is positioned on the pull rod and configured to move in the linear direction between a locked position and an unlocked position. The pull rod is configured to move in the linear direction from the back position toward the forward position when the collar is in the unlocked position, and the pull rod is blocked from moving from the back position when the collar is in the locked position. | 12-29-2011 |
| 20120032382 | MOVABLE WORK PIECE CLAMPING MECHANISM - Embodiments of the invention comprise a clamping mechanism for securing a work piece on a power tool having a working surface and a guide fence, the clamping mechanism including a support configured to be movable along the guide fence and a clamp interconnected to the support, the clamp being movable between a securing position and a release position, wherein in the securing position, the clamp engages a work piece, and in the release position, the clamp is disengaged from the work piece. | 02-09-2012 |

| 20090172876 | Pedestal sink towel holder, and towel holding method - A towel holder is removably outfitted upon a pedestal style sink for presenting both items to a user at a single station. The holder is formed from a single rod member uniquely bent to effect a three-dimensional structure having C-shaped lateral supports and a C-shaped central support. The lateral supports each have a free rod end, a lateral support end portion, and a rim-traversing-engaging portion. The central support has opposed central support end portions and a towel-support portion. The central and lateral support end portions integrally form opposed sink-engaging junctions. The free rod ends, rim-traversing-engaging portions, and sink-engaging junctions engage the sink, and the inherent weight of the rod member aligns the towel support portion relative to a sink rim. The towel support portion of the towel holder may thus bear a towel in adjacency to the pedestal sink. | 07-09-2009 |

The electrical power alternator makes electrical power available on a DC link having a voltage characteristic and a current characteristic. A method for managing the response of the alternator includes determining a voltage of the DC link and a torque command by an operator. The torque command is used to derive a mechanical power that is being commanded. A desired voltage of the DC link is determined based on the derived mechanical power, and an excitation voltage command signal is provided based on the desired voltage of the DC link by use of a closed loop controller. An actual excitation voltage is applied to the electrical power alternator based on the excitation voltage command signal. | 03-08-2012 |
