Abstract: A system for training welders that includes a data generating component, a data capturing component and a data processing and visualization component. The data generating component operates in real time and derives data from an actual manually-executed weld and further includes a weld process-specific jig, a calibration block positioned on the jig, wherein the geometric configuration of the calibration block is specific to a particular type of weld joint, a weld coupon positioned on the welding process-specific jig adjacent to the calibration block, a welding gun for use by a trainee, wherein the welding gun is operative to form the weld; and at least one target mounted on the welding gun that is recognized by the data processing and visualization component for providing multidimensional position and orientation feedback to the trainee.

Abstract: A hemostatic device includes a first tube defining a first lumen configured to channel a fluid therethrough, and a second tube housing at least a portion of the first tube and at least partially defining a second lumen configured to retain a hemocoagulant agent therein. The second tube is moveable with respect to the first tube, such that the hemocoagulant agent is at least substantially retained within the second lumen when the second tube is in a first position, and the hemocoagulant agent is at least partially exposed when the second tube is in a second position.

Abstract: A hemostatic system includes a first tube defining a first lumen configured to channel a fluid therethrough, a second tube housing at least a portion of the first tube and at least partially defining a second lumen configured to channel a hemocoagulant agent therethrough, a hopper coupled to the second tube, and an injection device. The hopper defines a cavity in fluid communication with the second lumen and is configured to retain the hemocoagulant agent therein. The injection device is selectively positionable within the second lumen and/or the cavity to facilitate channeling the hemocoagulant agent from the cavity through the second lumen.

Abstract: A hemostatic device is provided for sealing a puncture of a vessel. The hemostatic device includes a locator device and an injection tube coupled to the locator device. The locator device includes a device valve that is actuatable to selectively restrict access to a portion of the locator device. The hemostatic device is advanced into the vessel until a first fluid is channeled through the locator device. The device valve is actuated to selectively restrict the first fluid from being channeled through the locator device. A second fluid is injected through the injection tube to facilitate sealing a puncture of the vessel. The hemostatic device is withdrawn from the vessel.

Abstract: A hemostatic device includes an injection tube having at least one distal tube opening configured to discharge a first fluid to facilitate sealing the puncture. A guide is adjacent a distal end of the injection tube. The guide includes a cone-shaped portion having an apex oriented towards a distal end of the hemostatic device.

Abstract: A hemostatic system includes an inner tube and an injection sheath coupled to the inner tube. The injection sheath houses at least a section of the inner tube. The inner tube defines a first lumen configured to channel a fluid therethrough, and the injection sheath defines a second lumen configured to channel a hemocoagulant agent therethrough. An injection device is positionable within the injection sheath to facilitate channeling the hemocoagulant agent through the second lumen. The injection device defines a third lumen in fluid communication with the first lumen when the injection device is positioned within the injection sheath. The injection device includes a valve that is moveable to selectively restrict access to a portion of the injection device.

Abstract: A back-off tool for use in breaking a joint of a tubular disposed in a well. The tool is dual anchoring in nature such that breaking of the joint may be achieved with a degree of precision heretofore unavailable. Additionally, the dual anchoring nature of the tool at both sides of the joint allows for power requirements to be met through use of a dowhole power source incorporated into the tool. As a result, the use of heavier power carrying cables and equipment may be avoided as well as explosives or similarly hazardous and/or imprecise measures.

Abstract: A method and system for monitoring and characterizing the creation of a manual weld is disclosed. The system generally includes a welding gun having a target, an imaging system, a processor, and a display. During the creation of a manual weld, the imaging system captures a plurality of images of the target. The processor analyzes the plurality of images of the target to calculate a plurality of position and orientation characteristics associated with the manipulation of the welding gun during the welding process. The display illustrates at least one of the plurality of position and orientation characteristics to provide feedback regarding the creation of the weld. In one embodiment, the disclosed method and system may be utilized as a tool for training welders.

Abstract: A novel coaxial DC block with circumferential capacitive shielding is presented. The coaxial DC block includes an inner DC block electrically couplable to a first inner conductor of a first length of coaxial cable and electrically couplable to a second inner conductor of a second length of coaxial cable. The inner DC block provides a capacitance which capacitively couples the first inner conductor to the second inner conductor and blocks a first frequency range of interest. The inner DC block is electrically sealed and shielded by a capacitive sleeve that is concentrically arranged to form a Faraday cage around the inner DC block. The capacitive sleeve is electrically couplable to a first outer conductor of the first length of coaxial cable and electrically couplable to a second outer conductor of the second length of coaxial cable.
