摘要:
A fully automated method is performed on a structure having a confined space. The structure has a location that is identifiable from within the confined space and from outside the confined space. A first robotic system moves a first end effector inside the confined space such that the first end effector is positioned over the location. A first vector corresponding to the location is generated. A second robotic system moves a second end effector outside the confined space such that the second end effector is positioned over the location. A second vector corresponding to the location is generated. The first and second vectors are used to move the first and second end effectors to a new location such that the first and second end effectors are in working opposition. The first and second end effectors perform a synchronous operation at the new location.

A plain journal bearing (20) coupling a first component (21) to a second component (22). A pin (26, 27) passes through the first component (21) and the second component (22). A clamping bush (31, 32) surrounds the pin and has a cylindrical inner surface and a cylindrical outer surface. A clamping member (29a) is mounted on the pin and provides a clamping force to urge the clamping bush (31, 32) into clamping engagement with the first component. The bearing (20) has a primary slip path between the outer surface of the clamping bush (31, 32) and the second component (22) which is arranged to operate such that during normal operation of the bearing, when the first and second component rotate relative to each other, the second component (22) and the clamping bush (31, 32) rotate relative to each other about the primary slip path and the clamping bush (31, 32) remains in clamping engagement with the first component (21). The pin (26, 27) also has a cylindrical outer surface which provides a subsidiary slip path which is arranged to operate such that during degraded operation of the bearing (20), when the first (21) and second (22) component rotate relative to each other and the coefficient of friction of the primary slip path has increased to overcome the clamping force, the pin (26, 27) and the clamping bush (31, 32)or the pin (26, 27) and the first component (21) rotate relative to each other about the subsidiary slip path.

A fastener system for composite structure provides electromagnetic energy protection by incorporating a self-aligning head (SAH) fastener having a head with a spherical engaging surface and a shank extending from the head for insertion through a hole in a composite structure and a self-aligning self sealing (SASS) washer having a throat receiving the shank and a spherical mating surface interfacing with the spherical engaging surface of the head.

Golf club heads are releasably engaged with shafts so they may be readily interchanged and/or so that the shaft orientation with respect to the club head can be readily changed. Assemblies for connecting the club head and shaft may include a shaft adapter and a head adapter. The shaft adapter may have an exterior surface extending along a first axis and a bore having a cross-sectional shape along a second axis configured to attach to a shaft member. The second end of the shaft adapter may have a cross-sectional shape of a regular polygon or a cross-sectional shape defined by splines. The head adapter has a first end and a second end along a first axis and a bore having either a shape of a regular polygon or a cross-sectional shape defined by splines along a second axis that is shaped to receive the second end of the shaft adapter in a plurality of orientations.

An annuloplasty repair segment for heart valve annulus repair. In one embodiment a multi-stranded cable replaces solid core wire for both the tricuspid and mitral valves. Cable allows for greater deployment flexibility for minimally-invasive surgical (MIS) implant, while still maintaining the required strength and similar tensile properties of solid-core wire. Stranded cable provides a MIS annuloplasty ring with sufficient flexibility in the x-y plane to allow a surgeon to squeeze the ring into a small incision, such as being able to pass through an 18 Fr or smaller catheter, while maintaining structural rigidity under forces exerted on the implanted ring by the cardiac cycle. The particular shape of the annuloplasty ring is fixed using a heat setting process.

An automated tool includes a quick change spindle assembly (23). In another aspect of the present invention, the quick change spindle (45) includes an attachment assembly (49) for interchangeable fastener drivers (38). A further aspect of the present invention employs release member (75) to actuate a drive member (61) in the spindle assembly causing a retainer to uncouple a fastener driver with the spindle.

A method includes joining an integral bulkhead (20) and a blade shell (22, 24) to form a blade (12) and separating the blade into two blade segments at a location including the integral bulkhead such that each blade segment comprises a portion of the integral bulkhead and a portion of the blade shell.
