A method for manufacturing a centralizer assembly includes reducing a diameter of a mandrel such that a turned-down region is formed in the mandrel, positioning a first stop segment in the turned-down region, and positioning a centralizer at least partially in the turned-down region, wherein the first stop segment is positioned intermediate of axial extents of the centralizer, such that the first stop segment at least partially limits a range of motion of the centralizer relative to the mandrel

An ophthalmic surgical instrument comprises a multi-diameter shaft, a horn fixedly threaded into the shaft, a surgical tip for ophthalmic surgery including a tip end and threadably engaging the horn opposite the shaft, and a plug on the shaft. Weld material holds the plug on the shaft in a selected angular and longitudinal position with an angle-locating recess on the plug's circumference having a predetermined angular clocked relation to a face direction of the tip end. The plug's recess engages an irrigation tube on a subassembled handle with shell and irrigation tube, such that the subassembled handle has a known clocked position relative to the tip end of the tip, thus facilitating use by a surgeon. A related method is also disclosed and claimed.

A power tool including a moveable piston, a motor capable of driving the moveable piston to perform work on a work piece, and a distance sensor configured to sense a movement of the moveable piston. The distance sensor operable to provide sensor information indicative of the movement of the piston. A controller receives the sensor information from the distance sensor. The controller operates the motor to perform work on the work piece based in part on the sensor information that the controller receives from the distance sensor.

The invention relates to a support (10) for a headrest, comprising a tube leg (11) to which a head support part can be attached and having at least one free end (12a, 12b) for anchoring the support (10) in a seat fitting of an automobile seat, at least one reinforcing sleeve (15) being in the tube leg (11) for reinforcing at least one area (25) of the tube leg (11). The characterizing feature is that an outer surface (16) of the reinforcing sleeve (15) is in contact with an inner surface (17) of the tube leg (11) in a first circumferential region (T1) and that, in a second circumferential region (T2), the outer surface (16) has a groove (23) into which a ridge (22) projecting inward past the inner surface (17) engages.
