Abstract: A stress monitoring method includes the steps of acquiring a plurality of individual readings of at least one physiologic data parameter over a period of time, storing the plurality of individual readings, determining the average of at least a portion of the plurality of individual readings, and comparing at least one individual reading to the average to identify any differences between the average and the at least one individual reading.

Abstract: An adaptor for securing an elongated workpiece, such as an elongated pin, in a workpiece fixture is disclosed, wherein the adaptor is adjustable for repositioning the workpiece to facilitate a machining operation thereon. The adaptor includes a holding assembly for holding a workpiece in the adaptor and a securing assembly for securing the holding assembly in a workpiece fixture so that the workpiece and the holding assembly are repositionable with respect to the fixture. In a first embodiment of the adaptor, the securing assembly is operable for repositioning the holding assembly in a horizontal direction which is substantially perpendicular to the longitudinal extent of the workpiece, whereas in a second embodiment of the adaptor the securing assembly is operable for repositioning the holding assembly in both horizontal and vertical directions.
