Abstract: Movable platforms for use with a vehicle capture assembly of a capture vehicle and related devices, systems, and methods include floors with rotatable legs extending between the floors. The rotation of the legs relative to one or more of the floors enables the movable platform to move from an initial position to a displaced position as one or more of the floors move relative to each other.

Abstract: A sand screen assembly for a subterranean wellbore includes a base pipe having a central axis and including a flow port extending radially therethrough. The sand screen assembly also includes a screen element disposed about the base pipe and radially spaced from the base pipe to define an annulus radially positioned between the screen element and the base pipe. In addition, the sand screen assembly includes a manifold formed about the based pipe. The flow port is in fluid communication with the manifold and axially overlaps with the manifold. Further, the sand screen assembly includes a phase change material disposed within the manifold. The phase change material is configured to melt at a temperature below a melting temperature of the base pipe and flow into the flow port.

Abstract: An illustrative example method of monitoring value added activity includes positioning a detector near a selected portion of a machine using a clip for situating the detector in a position where the detector can detect at least one electrical characteristic associated with operation of a machine; communicating an indication of the detected electrical characteristic between the detector and a user interface; and displaying a visual representation of value added activity information based the indication. The value added activity corresponds to human operator performance that is distinct from machine performance during a manufacturing or assembly process.

Abstract: Techniques are described for automatically distributing validated user safety alerts from a networked computing device. The networked computing device may be configured to operate as an autonomous agent to perform actions on behalf of a user without receiving direct instructions from the user. For example, the autonomous agent computing device may be configured to make certain purchases, send alerts or reminders, or perform other functions in accordance with preprogrammed rules. According to the disclosed techniques, the autonomous agent computing device is configured to automatically generate and send an alert to one or more computing devices associated with the user upon detecting a safety concern for the user. The autonomous agent also uses a signing key associated with its digital certificate, which verifies the identity of the autonomous agent, to sign the alert such that a third-party server may validate the alert prior to distribution to the destination computing devices.

Abstract: Bypass devices are disclosed for providing alternative flow paths within an annulus formed around a production string of a subterranean wellbore. In some embodiments, the bypass devices include inlet flow paths and outlet flow paths in fluid communication with the annulus so that fluids may flow through the inlet and outlet flow paths to bypass a blockage in the annulus. The bypass devices are also configured to avoid internal blockages within the internal flow paths defined by the inlet flow paths and outlet flow paths.

Abstract: A downhole valve has a closure device (e.g., one or more flappers) for closing off the valve. A no-go actuation mechanism protects the flappers from damage. When the flappers are closed, the mechanism prevents a tool from passing into the valve and causing damage to the flappers. Yet, the mechanism may open the valve's flappers when the tool string is forced into the valve. When the valve has successfully opened, then the mechanism moves out of the way of the toolstring so it can pass through the valve. For the mechanically operated valves, operators use a shifting profile in the valve only in the upward direction to return the valve to the closed position. For hydraulic actuated valves, hydraulic pressure may be used or exhausted, depending on the design, to allow the flappers to go closed. Once the flappers have closed, the no-go mechanism is once again realized.

Abstract: Systems and methods sense out-of-plane linear accelerations. In an exemplary embodiment, the out-of plane linear accelerometer is accelerated in an out-of-plane direction, wherein the acceleration generates a rotational torque to an unbalanced proof mass. A rebalancing force is applied to at least one plurality of interleaved rotor comb tines and stator comb tines, wherein the rebalancing force opposes the rotational torque, wherein the rotor comb tines are disposed at an end of the unbalanced proof mass, and wherein the stator comb tines are disposed on a stator adjacent to the end of the unbalanced proof mass. An amount of acceleration is then determined based upon the applied rebalancing force.

The rotor tines include a first section extending a first distance from an insulating layer of the rotor tines and a second section extending a second distance from the insulating layer in an opposite direction from the first section. The stator tines include a first section extending a first distance from an insulating layer of the stator tines and a second section extending a second distance from the insulating layer in an opposite direction from the first section, the stator tine first distance being greater than the rotor tine first distance.

Abstract: Downhole tools, such as a sliding sleeve or an openhole type packer, include position indicators. The position indicators can include one or more magnets disposed in predetermined positions in the outer housing and the insert of the sliding sleeve. A casing collar locator (CCL) can be used to detect the magnets and determine the relative positions of the housing magnets and insert magnets. The relative positions of the magnets can be used to determine the operational condition of the downhole tool, i.e., whether a sliding sleeve is open or closed or how much a sealing element of an openhole type packer had to expand to seal an annulus.
