Automatic recovery of locking filesystem shared between virtual tape library nodes
A virtual tape library system includes multiple copies of a LockFS that are mounted on all nodes. One of the LockFSs is designated as the active copy. A primary node manages recovery when a secondary node signals loss of connectivity with the active copy by posting a sync request file to at least one of the LockFSs. The primary node posts status request files to the LockFSs and the secondary nodes respond by writing status to the status request files. A LockFS that is reachable by all nodes is selected as the new active LockFS. Switchover is accomplished by the primary node posting a disable request file to the selected LockFS and waiting for all secondary nodes to acknowledge by writing to the disable request file. The primary node then posts an activate request file to the selected LockFS and waits for all secondary nodes to acknowledge by writing to the activate request file. |

Atomic clock with atom-trap enhanced oscillator regulation
A rubidium optical atomic clock uses a modulated 778 nanometer (nm) probe beam and its reflection to excite rubidium 87 atoms, some of which emit 758.8 nm fluorescence as they decay back to the ground state. A spectral filter rejects scatter of the 778 nm probe beams while transmitting the 775.8 nm fluorescence so that the latter can be detected with a high signal-to-noise ratio. Since the spectral filter is only acceptably effective at angles of incidence less than 8° from the perpendicular, the atoms are localized by a magneto-optical trap so that most of the atoms lie within a conical volume defined by the 8° angle so that the resulting fluorescence detection signal has a high signal-to-noise ratio. The fluorescence detection signal can be demodulated to provide an error signal from which desired adjustments to the oscillator frequency can be calculated. |

Systems, methods, and apparatus for recoil mitigation
The present invention provides a novel gas impingement and recoil mitigation system for firearms that includes separate systems that reduce recoil, muzzle rise, and user fatigue and includes a system that is of variable size to match the size and caliber of firearm to which the system will attach. The system can attach to a variety of firearms through an appropriately sized standard barrel connector. As propellant gas is redirected through a ported barrel, the force of the over-pressure wave caused by the propellant blast impinges on a piston-like weight-and-spring mechanism, which thrusts forward with a force that is opposite in direction from the typical backward force that causes muzzle rise and recoil. Numerous additional aspects are disclosed. |
