Abstract: A metrology system includes a laser, a position sensitive detector array, a first collimator, a second collimator, and a mirror. The position sensitive detector array and the first collimator are positioned at a reference point. The second collimator and the mirror are positioned at a point target at a distance from the reference point. A laser beam is alternately provided to the first collimator and the second collimator by optical fiber. The position sensitive detector array measures position data from a first laser crosshair generated by the first collimator and from a second laser crosshair generated by the second collimator. By alternating the activation of the first collimator and the second collimator it is possible to measure 5 degrees-of-freedom for the point target. A metrology system processing unit provides analog data processing. The metrology system that is suitable for, but not limited to, facilitating active compensation of large spacecraft structures.

Abstract: A device for gripping the external wall surface of a pipe or bar. The device includes a tubular body having at least one end open for insertion of a pipe or bar, and a cage with balls or rollers cooperating with a first tapered internal wall part of the body. A resilient mechanism pushes the cage in an axial direction to cause the balls or rollers to grip the external wall of an inserted pipe or bar. The device also has a compressible member located within the body and cooperating with a second tapered inner wall part of the body and movable relative thereto when increased fluid pressure is present within the body. Under increased pressure it also grips the external wall of the inserted pipe or bar.

Abstract: The present invention relates to a method for promoting blood vessel formation in tissues and organs. In particular, the method relates to implantation or attachment of an engineered three-dimensional stromal tissue to promote endothelialization and angiogenesis in the heart and related tissues. The three-dimensional stromal tissue of the present invention may be used in a variety of applications including, but not limited to, promoting repair of and regeneration of damaged cardiac muscle, promoting vascularization and healing during cardiac surgery, promoting blood vessel formation at anastomosis sites, and promoting vascularization and repair of damaged skeletal muscle, smooth muscle or connective tissue.

Abstract: To obviate the need for hydraulic lines, from the surface, external water pressure is used to compress a seal member and form a seal with a surrounding pip. Valve is opened at depth to allow water to act on a piston, moving it within a chamber so as to compress the seal member. A second valve may be opened so that water acts on the opposite end of the piston to release the seal member.

Abstract: A system for measurement of a differential delay between a primary signal and a secondary signal or signals, propagating between a nominal source and a nominal destination. The source has a first detection unit for the detecting of a rapid change in a given parameter of the primary signal, and an applying unit for applying a timing signal containing timing information relating to the rapid change in the parameter of the primary signal detected by the first detection unit to the secondary signal(s). The destination has a second detection unit for the detection of a rapid change in the given parameter of the primary signal, a recovery unit for recovering the timing signal from the secondary signal(s) and a third detection unit for the detection of the timing information relating to the rapid changes in the parameter of the primary signal from the recovered timing signal.

Abstract: A retaining device to prevent linear movement of an elongate member (10) in the downwards direction comprising a plurality of segmental ball slips (14) surrounding the member (10) and removably introduced into a tapered opening in a supported bushing (13), each ball slip (14) including a ball cage (18) having balls (20) and ramps (21) and a spring (19) urging the ball cage downwardly and thus the balls inwardly to grip the elongate member with a smooth rolling action preventing surface damage to the elongate member. The ball slips (14) may be hinged together around the elongate member (10) and may removed manually or by power operated means at (22).

Abstract: A method for testing an electronic module to evaluate solder joint failures caused by thermally induced stress includes determining a thermal shock endurance test profile that represents field temperature conditions, estimating time/cycles to failure of solder joints in the module using numerical simulation techniques, selecting a design life duration for the module, comparing the design life duration of the module with the estimated time/cycles to failure of the weakest solder joint in the module, determining between robust, marginal, and non-robust module designs based on the design life duration of the module and the estimated time/cycles to failure of the at least one solder joint in the module, and determining an accelerated thermal shock endurance test specification having a test duration for testing the electronic module upon determining a marginal module design.

Abstract: A universal test fixture assembly for circuit packs includes a test fixture body, a top guide plate and a bottom guide plate. Each guide plate includes tracks that extend from a front end to a second end of the guide plates and further includes an integrally formed latching channel that runs perpendicular to the tracks. The top guide plate and bottom guide plate are mounted in an opposing and matching relationship such that the circuit pack slidably engages one of the tracks in the top guide plate and a corresponding track in the bottom guide plate and are moveable relative to one another to accommodate circuit packs of varying sizes. The guide plates include tabs which mate with corresponding slots on the test fixture body to prevent misalignment and reduce tolerance build-ups. A second pair of guide plates are attachable to form a two-tiered structure such that two different circuit pack sizes can be accommodated in the same test fixture.

Abstract: A marine propulsion unit including a conduit having opposed, inlet and outlet ends. A first pivot pin is pivotally secured within the conduit adjacent its inlet end. A second pivot pin is pivotally secured within the conduit adjacent its outlet end. The forward end of a flexible sheet is secured to the first pivot pin, and the rearward end of the flexible sheet extends freely from the outlet end of the conduit. The flexible sheet is also secured to the second pivot pin between the forward and rearward ends thereof in a longitudinally compressed manner so as to impart a waveform to the flexible sheet. At least one crank arm is secured to the first pivot pin for oscillating the first pivot pin to cause the rearward migration of the waveform in the flexible sheet from the first pivot pin to the second pivot pin.

Abstract: An alarm significance mapping method assigns the subset of parameters and their alarms considered to be of a safety-critical nature in an industrial control system and displays that subset on an apex screen display and other selected appropriate displays, such as a touch-responsive display in the form of alarm icons for presentation to the system operators. Each alarm icon on the `apex` display is coupled or concatenated to other displays through a display page hierarchy so that the operator, by selecting a particular alarm icon on the `apex` screen, can follow the alarm `thread` through the multi-level display page hierarchy to the ultimate condition or conditions that cause an alarm on the `apex` screen.
