Abstract: A method for proactively rebuilding user data in a plurality of storage nodes of a storage cluster in a single chassis is provided. The method includes distributing user data and metadata throughout the plurality of storage nodes such that the plurality of storage nodes can read the user data, using erasure coding, despite loss of two of the plurality of storage nodes. The method includes determining to rebuild the user data for one of the plurality of storage nodes in the absences of an error condition. The method includes rebuilding the user data for the one of the plurality of storage nodes. A plurality of storage nodes within a single chassis that can proactively rebuild the user data stored within the storage nodes is also provided.

Abstract: Systems and methods for just in time (JIT) video on demand (VoD) transcoding using a computed context are provided. The context for each segment is computed rather than collected from the prior segment, thereby allowing for very short playback timing compared to batch transcoding techniques. Computed context requires the setting of a predictable media segment size, computing of a predictable playback time stamp (PTS) as a function of the predictable media segment size and a derived time offset value, and generating a prior audio segment including a priming portion and discard samples, and a “real” audio segments including playback samples. Then generating another primed segment for the time period of the “real” audio segment, and a subsequent “real” audio segment. This doubles the computational resources required over batch audio transcoding.

Abstract: A gas supply system for a mechanical seal turns on the gas supply at a pressurized flow rate at the time of compressor case pressurization and remains on during compressor rotation until pressure is adequate. The gas supply system has an intensifier that includes a pair of mechanically inter-connected pneumatic pressure cylinders which comprise a drive cylinder that affects movement of a boost cylinder wherein the displacement of these mechanically interconnected pistons in the drive cylinder and boost cylinder intensifies the pressure being discharged by the boost cylinder and supplied as a barrier fluid to the mechanical seal. The intensifier uses a control valve and operating system which includes a fast-acting 5/2-way solenoid valve having a feedback loop connected to a control system which includes a microprocessor that controls valve actuation.

Abstract: An electrical submersible pump system includes an electric motor operably coupled to a fluid pump which includes first and second fluid ports. The first and second ports are selectively operable as a fluid intake and a fluid discharge of the fluid pump with reversal of a direction of rotation of the fluid pump. Valves in the system are controllable to selectively direct fluid discharge of the fluid pump to an inflation volume of the inflatable packer and toward the surface in a wellbore tubing. The valves are further controllable to vent pressure in the inflation volume to deflate the packer.

Abstract: A user input device support apparatus is provided for supporting right or left handed users of a computer keyboard and mouse. The user input support apparatus includes a base configured to couple to a mobile or fixed mounting system. The keyboard support further includes a tray configured for supporting a user input device, such as a computer keyboard. Further, the tray includes a lip, wherein the lip is configured to at least partially engage the base. Here, the tray is further configured to slide with respect to the base, thereby accommodating right or left-handed users of the keyboard and a mouse.

Abstract: A bearing for a rotary machine includes an inner sleeve providing a first bearing surface and an outer sleeve circumscribing the inner sleeve and providing a second bearing surface in opposing relation to the first bearing surface. The bearing includes at least one tolerance ring for retaining the inner sleeve on a rotor shaft of the rotary machine and another tolerance ring for retaining the outer sleeve on a stator of the rotary machine.

Abstract: A system and method for rapidly and reliably sealing off a selected opening from the passage of smoke, noxious fumes, or contaminated air includes a powered clutch and viscous governor that provides a fail-safe mode of operation. A curtain is positioned in a housing adjacent to an upper limit of an opening such as a hoist access-way. The curtain is wrapped around a spindle that is connected to a spool via two cords. The curtain is held in the housing in a stored configuration by a powered clutch so that upon removal of power, either via a controller or by power loss, the clutch releases the spool allowing the cord to unwind lowering and thus deploying the curtain. A capacitor can be included to prevent inadvertent deployments due to momentary power loss. The speed at which the spool rotates, and correspondingly the curtain deploys, is limited by a viscous governor coupled to the spool.
