The present disclosure relates a device that includes a rotary union body. Included with the rotary union body is a circumferential air channel, a seal channel, and an intake air channel. The intake air channel is connected to the circumferential air channel. Also disclosed is a hub assembly system that includes a hub and a rotary union body. Included with the rotary union body is a circumferential air channel, a seal channel and an intake air channel. Here the intake air channel is connected to the circumferential air channel.

A set of commands for each of a plurality of actuators to alter an aircraft's state responsive to one or more inputs is produced. The set of commands is provided to fewer than all actuators comprising the plurality of actuators.

Distributed flight control system

A system and method for improved redundancy in storage devices are disclosed. The method includes receiving a first data block for writing to a storage device; writing the first block to a journal connected with the storage device; associating a first logical address of a group of logical addresses of the journal with a first physical address of the storage; associating the first physical address to an additional second logical address of the storage device, the second logical address not of the group of logical addresses of the journal; and disassociating the first physical address from the first logical address, in response to associating the first physical address with the additional second logical address.

Networked storage redundancy scheme

A unit of data is read from memory of a replicated cache. The replicated cache comprises a plurality of independent computing devices. Each independent computing device comprises a processor and a portion of the memory. Confirmations are received from at least a majority of the independent computing devices that a flush operation for the unit of data was initiated no later than a time indicated by the timestamp and that a more recent version of the unit of data has not been flushed. The unit of data is provided to storage.

Operating a replicated cache that includes receiving confirmation that a flush operation was initiated

Embodiments of the present invention are directed to methods, and distributed data-storage systems employing the methods, for recovering redundancy within a distributed data-storage system upon failure of one or more mass-storage devices within a component data-storage system of the distributed data-storage system. In certain embodiments, failure of a mass-storage device within a component data-storage system elicits a redundancy-recovery operation in which segments affected by the mass-storage-device failure or failures are moved, by a process referred to as 'migration,' to other component data-storage systems of the distributed data-storage system, and are recovered as a by-product of migration. Certain embodiments of the present invention more efficiently address redundancy recovery by moving only as many segments from the component data-storage system as needed to provide sufficient free space within the component data-storage system to recover the remaining segments affected by the mass-storage-device failure or failures within the component data-storage system.

Sufficient free space for redundancy recovery within a distributed data-storage system

Data blocks are read from a distributed cache. The distributed cache comprises m replicated caches, each replicated cache including a plurality of independent computing devices. Each independent computing device of the replicated caches holds a replica of a particular one of the m data blocks in memory. The m data blocks and p parity blocks are stored across m plus p independent computing devices. Each of the m plus p independent computing devices stores a single block selected from the m data blocks and the p parity blocks.

Method of operating distributed storage system in which data is read from replicated caches and stored as erasure-coded data

Embodiments of the present invention are directed to digitally encoded hierarchical timestamps that are stored in computer readable mediums. The hierarchical timestamps of the present invention include a first field that stores a timestamp value and a second field that stores a processing-level indication that indicates the scope of the timestamp within a hierarchical processing system.

An optical cable shield layer connection may include a wire electrically connected to a shield layer of an optical cable. The optical cable shield layer connection may also be sealed, for example, to prevent leak paths. The optical cable shield layer connection may be made when coupling the optical cable to a device or another cable, for example, using a universal joint such as the Millennia&#xae; Joint available from Tyco Telecommunications (U.S.) Inc. The wire may provide a ground path from the shield layer or a continuity path from the shield layer to another optical cable.
