Storage management of data using an open-archive architecture, including streamlined access to primary data originally stored on network-attached storage and archived to secondary storage
An illustrative “open archive” architecture provides streamlined access to production data, which originally was stored on a NAS device but which is archived to secondary storage to free up NAS space. An open-archive server coordinates with an open-archive layer on the NAS device. The open-archive server identifies data sets on the NAS that meet archiving criteria, which are then automatically moved to an open archive in secondary storage. The open archive layer intercepts data-access calls coming into the NAS device, and reports the intercepted calls to the open-archive server. If the open-archive server determines that the data referenced in an intercepted call is in the open archive, the server initiates a restore job that recovers the data from secondary storage and stores it back on the NAS device. The intercepted call may now be served from the NAS. These operations occur automatically and without data agents for the NAS-based data. |

Live recovery of virtual machines in a public cloud computing environment
Live recovery generates a new “recovery VM” that operates as an ongoing “live” production platform. A previously created non-cloud-native backup copy is the data source for the recovery VM. Live recovery restores data blocks from the backup copy on backup media directly to cloud-based virtual disk(s) assigned to the recovery VM. As a result, the cloud-based recovery VM can become fully operational in the cloud computing environment on a going-forward basis. The advantage of live recovery over a traditional restore is that live recovery provides a cloud-based VM that begins operating well before the backup copy is fully restored. This is accomplished by temporarily mounting a “temp-mounted VM” in the cloud while the backup copy is methodically restored in the background. VM reads and writes begin issuing from the temp-mounted VM and writes are retained on completion. Downtime is minimized when switching from the temp-mounted VM to the recovery VM. |

Techniques of deriving audio signals using frequency modulated continuous-wave (FMCW) LIDAR use an acceleration-based algorithm in which an audio signal is based on a difference in velocity between two up-chirps or two-down-chirps.

HVAC on demand via high and low pressure vortex separation apparatus with rotating spin chamber
The HVAC On Demand Via High And Low Pressure Vortex Separation Apparatus With Rotating Spin Chamber is a novel heating and cooling system that could revolutionize the HVAC industry.

A generally polygonal retaining ring of elastically deformable wire is installed partially in the arm groove and partially in the pin groove to retain the poppet on the pin, thereby attaching the poppet to the arm of the valve member. An anti-rotation feature prevents relative rotation of the poppet about the pin axis. Vertices of the retaining ring are in the arm groove, while sides of the retaining ring are in the pin groove. Once the retaining ring is pre-installed in the arm groove of the arm, the arm can be assembled to the poppet by a push-to-connect process. |

Fluid pump and outlet check valve assembly thereof
A fluid pump includes a housing; an inlet passage; an outlet conduit; a pumping element within the housing; and a check valve assembly. The check valve assembly includes a valve stem within the outlet conduit such that a flow path is created radially between the outlet conduit and the valve stem, the valve stem moving along a check valve assembly axis between a closed position and an open position. The flow path includes a first restriction which increases velocity of fluid passing through the flow path; a first expansion, downstream of the first restriction, which decreases velocity of fluid passing through the flow path; a second restriction, downstream of the first expansion, which increases velocity of fluid passing through the flow path; and a second expansion, downstream of the second restriction, which decreases velocity of fluid passing through the flow path. |

Fluid working systems
A fluid working system such as a pump for displacing a working fluid such as hydraulic fluid or a motor using a working fluid is provided. The system may have a positive displacement machine which includes one or more working chamber with displacement means such as a cylinder with a reciprocating piston. There are also two or more fluid ports to allow the working fluid to flow into and out of the working chamber. The working fluid flows from one fluid port means to another either being forced to do so when pumped or moving the piston when functioning as an engine. The fluid working system has associated therewith a non-dead compliance volume of a material such as syntactic foam. This compliance volume acts to smooth any pressure fluctuations within the working fluid system. |

Rotary diaphragm positive displacement pump
A rotary pump comprising a housing (1) defining an annular chamber with inlet and outlet ports (12;11) spaced apart around the chamber, a flexible annular diaphragm (3) forming one side of the chamber spaced opposite an annular wall of the housing (1), the diaphragm (3) being sealed at its edges to the housing (1), a partition (13) extending across the chamber from a location between the inlet and outlet ports (12;11) to the diaphragm (3). The diaphragm (3) is configured to be pressed progressively against the opposite wall of the housing (1) to force fluid drawn in at the inlet port (12) on one side of the partition (13) around the chamber and to expel it at the outlet port (11) at the other side of the partition (13). The outer face of the annular diaphragm (3) has a trough (40) at the part of the diaphragm (3) which faces the inlet port (12) and/or at the part of the diaphragm 3 which faces the outlet port (11). |
