摘要： A blowout preventer includes a housing having a flow path therethrough in fluid communication with a wellbore penetrating a subsurface formation and a sealing assembly positionable in the housing about the flow path. The sealing assembly includes a piston slidably positionable in the housing and a packer element. The packer element includes a plurality of fingers and a packer seal. The fingers include a housing portion and a piston portion. The housing portion is slidably movable along the housing and the piston portion is slidingly movable along the piston. The fingers are engageable by the piston and movable to a sealed position about the flow path, and the packer seal is energized to form a seal about the blowout preventer to seal the wellbore in the subsurface formation.

摘要： A fastening tool (20) is provided with a housing (22) having a fastener outlet (28). A striker (30) is mounted for translation in the housing to drive a fastener from the fastener outlet in an unloaded position. A biasing member (34) cooperates with the striker to urge the striker towards the unloaded position. A motor (38) is oriented in the housing. A cam (42) is driven by the motor, and has a cam surface (44) in cooperation with the striker such that rotation of the cam translates the striker to a loaded position and to a release position whereby the biasing member drives the striker to the unloaded position. The cam surface is profiled to require a constant torque from the rotary input during translation of the striker to the loaded position while loading the biasing member.

摘要： A method includes receiving a signal, which carries data that is encoded with an Error Correction Code (ECC), and correcting the received signal with an adaptive receiver loop. Soft input metrics for the data are computed over the corrected signal. The ECC is decoded using a decoder, which estimates soft output metrics based on the soft input metrics, by operating the decoder in an alternating pattern of external iterations that update one or more of the soft input metrics based on one or more of the soft output metrics, and internal iterations that update the soft output metrics but not the soft input metrics. The adaptive receiver loop is adjusted in a schedule that is defined relative to the pattern of the external and the internal iterations of the decoder.

摘要： Communication apparatus (34) includes a one-way, hardware-actuated data relay (56), which includes a first hardware interface configured to receive a command from a communications network (30) and a second hardware interface configured to convey the received command to a protected destination (26) when the relay is actuated. A decoder (54) includes a third hardware interface (46) configured to receive a digital signature for the command from the communications network and hardware decoding logic coupled to verify the digital signature and to actuate the relay upon verifying the digital signature, whereby the command is conveyed via the second hardware interface to the protected destination.

摘要： A system for tracking pipe activity on a rig includes a plurality of pipes, each pipe having an asset ID tag containing a code unique to the pipe. A pipe handling space for assembling and disassembling the pipes contains at least one pipe handling apparatus. A first scanning zone located at a first position in the pipe handling space contains a first reader antenna. A second scanning zone located at a second position in the pipe handling space contains a second reader antenna. At least one reader is provided for scanning the asset ID tags in the pipe handling space through at least one of the first reader antenna and the second reader antenna.

摘要： A method for depth mapping includes illuminating an object with a time-coded pattern and capturing images of the time-coded pattern on the object using a matrix of detector elements. The time-coded pattern in the captured images is decoded using processing circuitry embedded in each of the detector elements so as to generate respective digital shift values, which are converted into depth coordinates.
