ABSTRACT:
The apparatus in one embodiment may have: a beam having at least first and second mounting points that are operatively coupled to the beam by first and second flexures, respectivly; the beam having first and second nodal points; the beam having a center area; and an altered mass content in a vicinity of the center area, the altered mass content being such that the first and second nodal points are substantially aligned with the first and second flexures. The beam is therefore supported at the nodal points for the fundamental mode of vibration.
