Abstract: A system for ejecting specimen samples includes a tray having a plurality of tray guide members and a plurality of holders configured to hold specimen samples. The system includes an ejector tool configured to eject the specimen samples. The ejector tool includes a base, a plurality of protruding members positioned on and extending away from the base, and a plurality of ejector guide members positioned on and extending away from the base and configured to engage the plurality of tray guide members of the tray such as to position the plurality of protruding members relative to specimen samples held in the tray. The plurality of protruding portions is configured to be inserted into the plurality of holders of the tray such that the plurality of protruding portions ejects the specimen samples from the plurality of holders.

Abstract: A method and apparatus for determining the mass moment of inertia of a given object is disclosed, The apparatus is a mass moment of inertia platform whereon objects to be measured can be placed. The platform uses flex pivots as torsional springs and the method ensures the flex pivots are procured and assembled in such a way so as to limit flex pivot misalignment systemic errors thereby resulting in a highly accurate and low-cost apparatus for measuring the mass moment of inertia.
