The weights vary between data from different sensors, with the weights assigned based on the task currently being performed by the worker. A current safety score is assigned for the worker based on the calculation of a formula, with the formula using the assigned weights as coefficients to variables, with the variables being values obtained from the biometric data and the environmental data. The current safety score is compared to a safety threshold, and if the threshold is violated, an alert is generated to the worker.

  • Publication number: 20170009785
    Abstract: An apparatus for actuating a valve includes a first actuator having a first actuator housing and second actuator with a second actuator housing. A first plate is positioned within the first actuator housing and a second plate is positioned within the second actuator housing. An intermediate stem extends from a first pressure chamber of the first actuator housing to the second plate. A pressure media path extends through the intermediate stem and a second seal nut that extends into the second plate, the pressure media path providing fluid communication between the first pressure chamber, and a second pressure chamber of the second actuator housing. An injection port is open into one of the first pressure chamber and the second pressure chamber. The first plate and the second plate are movable in response to pressure media injected into the injection port, for actuating the valve.

  • Publication number: 20170009547
    Abstract: A hanger assembly for supporting a tubular member within an outer well member includes a slip bowl that is moveable between an expanded condition with an enlarged diameter and a contracted condition with a reduced diameter, and has a downward facing slip bowl shoulder on an outer diameter of the slip bowl. Slips with teeth on an inner diameter surface are carried by the slip bowl. The slips are moveable between a retracted position, and an extended position where the teeth protrude radially inward from the inner diameter of the slip bowl. A false bowl has a lower upward facing false bowl shoulder located on an inner diameter and is sized to selectively engage the downward facing slip bowl shoulder. The false bowl also has a downward facing landing shoulder located on an outer diameter that is sized to selectively engage a support shoulder of the outer well member.

  • Patent number: 9538974
    Abstract: Various methods and systems are provided for estimating and compensating for table deflection in reconstructed images. In one embodiment, a method for computed tomography (CT) imaging comprises reconstructing images from data acquired during a helical CT scan where table deflection parameters are estimated and the reconstruction is adjusted based on the table deflection parameters. In this way, images may be reconstructed without artifacts caused by table deflection.

  • Patent number: 9540829
    Abstract: The maintenance assembly, for workers to perform maintenance activities within a gas turbine engine, is capable of being arranged within a cavity, generally around a combustor, accessible from a manhole of the gas turbine engine. The maintenance assembly includes a platform, and an inflatable member cooperatively configured to the platform. The inflatable member is at a normal condition, when placed outside of the cavity, being at a deflated position and is at a working condition, when arranged within the cavity, being at inflated position so as to accommodate a shape coordinating the cavity in such a manner that the platform is advance within the cavity up to a predetermined level to enable the workers on the platform to reach at a predetermined position within the cavity to perform the maintenance activities.

  • Patent number: 9540940
    Abstract: A system includes a multi-stage turbine. The multi-stage turbine has an interstage seal extending axially between a first turbine stage and a second turbine stage. The interstage seal has an upper body that extends from an upstream seating arm to a downstream seating arm. The upstream and downstream seating arms are designed to constrain movement of the interstage seal along a radial direction of the multi-stage turbine. The interstage seal also has a lower body that extends from a seating end to a hook end. The seating end is designed to constrain movement of the interstage seal along the radial direction. The hook end has a protrusion that extends crosswise relative to a base of the lower body. The hook end is designed to constrain movement of the interstage seal along the radial direction and an axial direction of the multi-stage turbine.
