ABSTRACT:
A seismic sensor includes a frame, a pendulum pivotably mounted to the frame, a mechanism for sensing angular position of the pendulum, and a monolithic flat spring oriented between the frame and the pendulum for balancing the pendulum at an equilibrium position. The monolithic flat spring includes: (i) an operating region for providing a restoring force to the pendulum proportional to an angular displacement of the pendulum; and (ii) a suspension region for transmitting a force to a portion of the operating region and applying a negligible bending moment to the portion of the operating region.
