Abstract: A method and apparatus are provided for sensor fault prediction. A time-sequence of output values is received from a sensor. A plurality of features are extracted from the received values. A model is applied to the features to obtain a health score for the sensor. The trend of the health score over time is calculated to detect degrading performance of the sensor, and a time at which the sensor will become faulty is predicted.

Abstract: A method of installing a subsea tie-in conduit comprises unspooling or manufacturing a steel rigid lined pipeline (14) aboard an installation vessel and launching the pipeline progressively from the vessel (10) into water. A distal end of the tie-in conduit is coupled to a proximal end of the pipeline above the surface and is then launched into the water coupled to the pipeline. The suspended weight load of the pipeline is supported by an A&R wire (34) connected to the proximal end (38) of the pipeline, defining a load path that bypasses the tie-in conduit (30). A proximal end of the tie-in conduit may be suspended from that wire. The tie-in conduit is of composite or flexible pipe, hence being pliant relative to the lined rigid pipeline and maintaining its internal corrosion resistance. After landing on the seabed, the tie-in conduit may be deflected relative to the pipeline for connection to a subsea connection point.

Abstract: Various embodiments disclosed herein relate to support structures for transportation systems. In some embodiments, the support structure comprises a self-supporting arch assembly. The self-supporting arch assembly can be configured to support one or more devices in a transportation system, such as an antenna assembly configured to communicate with a train. In other embodiments, the support structure can comprise a hinged mast assembly comprising a hinge assembly and mast coupled to the hinge assembly. A device, such as an antenna assembly can be disposed at a distal portion of the mast.

Abstract: Apparatus and methods are provided for assembling and positioning a bottom hole assembly (BHA) or tool string within a wellbore. The tool string is run via coiled tubing. The apparatus includes a deployment unit operable at a wellsite to make up and run the downhole tool string into the wellbore. In an example, the deployment unit includes a reel of the coiled tubing, a snubbing unit operable to run downhole tools into the wellbore, an injector head operable to run the coiled tubing with the tool string connected with the coiled tubing, and a support structure operable to support the snubbing unit and the injector head above the wellbore.

Abstract: A method and system disclosed assigns first videos to hardware decoders having a first configuration. The hardware decoders in the first configuration are to decode the first videos for concurrent presentation on a display of a user device. The method and system receives an indication that second videos are to be presented on the display of the user device. The method and system determine a second configuration of the hardware decoders based on an estimated penalty for the second configuration. The method and system assigns the second videos to the hardware decoders for decoding according to the second configuration.

Abstract: A plug (10) comprising a body (12) having a base portion (22) and an upper portion (24), the base portion (22) being receivable in an outlet (14) of a bath to prevent water flow. An actuator (42) is provided within the body (12) being moveable from a retracted position to an extended position. A timer is operable such that when a time period has elapsed from activation of the timer, the actuator (42) moves from the retracted to the extended position. In the extended position, the actuator (42) moves the body (12) of the plug (10) to disengage the plug (10) from the outlet (14) such that water may flow outwardly through the outlet (14).

Abstract: A method for assigning videos to multi-stream and single-stream decoders is disclosed. The method determines a ranking of each of a plurality of videos. The method further identifies a type of each video for at least part of the plurality of videos. The method also determines a configuration of a plurality of hardware decoders to decode a subset of the plurality of videos for simultaneous presentation on a screen of a user device. The configuration may define a mode of each of the plurality of decoders. The method further assigns the subset of videos to the plurality of hardware decoders for decoding according to the configuration.

Abstract: Each fuel injector has a main nozzle and pilot nozzle. A main fuel manifold to supply fuel to the main nozzle of each fuel injector and pilot fuel manifold to supply fuel to the pilot nozzle of each fuel injector. The main fuel manifold includes plurality of flexible main fuel pipes. Also, plurality of cross-piece connectors including a stem and four arms. The stem of each connector mounted on one fuel injector. The first and third arms extend in opposite directions from the stem and second and fourth arms extend in opposite directions from the stem. Each fuel pipe interconnects the first arm of one connector with a third arm of an adjacent connector and each connector so the first and third arms are at an angle relative perpendicular to the axis of the annular combustion chamber casing so the main fuel manifold extends around the combustion chamber casing sinusoidally.

Abstract: A snowshoe with an integrated articulating link is provided, where a surface support structure and a foot connector plate are connected by a multi-axial articulating link. The surface support structure, the foot connector plate and the articulating link constitute a structural unit, a mono-construction. The multi-axial tilt motion in the articulating link is achieved by extension and compression in the material structure. The extension and compression in the material structure is controlled by one or more corrugations in the arms.
