发明名称 ACCELEROMETER WHOSE SEISMIC MASS IS SHAPED AS WHIFFLETREE
摘要 <p>An apparatus and method for suspending two or more force-versus-displacement sensors for measuring displacement of a pendular structure relative to a frame structure, wherein a suspension structure includes the frame and pendular structures, the pendular structure having a base structure suspended from the frame structure for rotation about a first axis, a beam structure spaced away from the first axis, and a flexure suspending the beam structure from the base structure for rotation about a second axis that is substantially perpendicular to the first axis. The flexure suspending the beam structure from the base structure is positioned substantially intermediate between suspension positions of the force-versus-displacement sensors, and constrains the beam structure to motion substantially within the plane of the pendular structure.</p>
