Abstract:
1. Apparatus for reducing sensitivity of an article to mechanical shock, the apparatus comprising: a frame; first and second planar masses mounted in the frame for bi-directional movement relative to the frame along a first axis of displacement; and a first lever pivotable about a first fulcrum secured to the frame, the lever having one end connected to the first mass and the other end connected to the second mass, and the fulcrum being disposed between the ends of the lever; whereby the torque exerted about the fulcrum by the first mass is countered by the torque exerted about the fulcrum by the second mass in response to a mechanical shock applied to the frame along the axis of displacement such that an article carried by the first mass in use has reduced sensitivity to the shock, and wherein the second mass comprises an actuator element responsive to input stimulus for moving the second mass relative to the frame along the axis of displacement to produce a corresponding movement of the first mass relative to the frame along the axis of displacement.
