摘要： A power tool with a motor, a housing, a transmission, an output spindle, a front bearing and a rear bearing. The motor has an output shaft. The transmission is disposed in the housing and receives a rotary input from the output shaft. The transmission includes an input planetary stage, which has an input planet carrier, and an output planetary stage. The output spindle is driven by the transmission and has a first end, which extends at least partly through the input planetary stage, and a second end opposite the first end. The front bearing is disposed between the output spindle and the housing to support the second end of the output spindle for rotation about the spindle axis. The rear bearing indirectly supports the first end of the output spindle in the housing for rotation about the spindle axis.

摘要： An expandable, implantable medical device, such as an intraluminal stent fabricated from polymeric materials, includes a plurality of elongated struts in consecutive series and alternating stress concentration junctions interconnecting ends of adjacent struts. When the stent is in an expanded condition, the adjacent struts form expanded substantial V-shapes and stresses are concentrated within the junctions. The junctions define pivot points for the respective attached, adjacent struts. Each of the pivot points is located substantially on a line bisecting the V-shapes formed by the struts, when the stent is expanded.

摘要： A clutch arrangement for use in a power tool having a multi-speed transmission assembly. The clutch arrangement includes a clutch member and a follower member. The clutch member is coupled to a member of the transmission assembly that is proximate the torsional input of the transmission assembly and which must be in a non-rotating position to permit the transmission assembly to perform a torque multiplication operation. The follower member is biased into engagement with the clutch member to inhibit relative rotation therebetween. As the clutch member and the transmission member are coupled to one another, the transmission assembly is able to perform a torque multiplication operation. When, however, the torsion that is exerted onto the clutch member is sufficient to overcome the frictional engagement between the follower and clutch members, the clutch member, and the transmission member, rotate, thereby inhibiting the capability of the transmission to continue to perform the torque multiplication operation.

摘要： An invasive device having an inductive coupling element. One embodiment of the invasive device includes a plurality of receive coils inductively coupled to a communicating coil. The receive coils are selectively tuned and detuned to receive MR signals for providing coordinate information used for device tracking. A second embodiment of the invasive device includes a receive coil having a plurality of winding elements separated from each other by different distances. A method of rapidly acquiring both the invasive device orientation and position information to dynamically adapt MR scan planes to continuously follow the invasive device relative to a target is provided. The target-navigation technique automatically defines the MR scan plane and a time domain multiplexing technique is applied for MR imaging and device tracking. Using these techniques, the acquired MR images shows both the invasive device and the target tissue.

摘要： A power tool with a housing, a multi-speed transmission and a switch mechanism. The switch mechanism has an actuator, a rail, a switch and first and second springs. The actuator is movable along a longitudinal axis of the transmission between a plurality of positions and is engaged to one or more members of the transmission at each of the plurality of actuator positions such that the transmission operates in a corresponding one of a plurality of different overall speed reduction ratios. The actuator is non-rotatably but axially slidably engaged to the housing. The rail is fixedly coupled to the actuator and is received through the switch such that the switch is mounted on the rail for sliding movement thereon. The first spring is disposed between the actuator and the switch and biases the switch away from the actuator. The second spring is disposed between the switch and an end of the rail opposite the actuator and biases biasing the switch away from the end of the rail.
