Patent ID: 8100017

Claim:
A testing apparatus for subjecting a device-under-test to oscillating acceleration, the testing apparatus comprising: a stage having a mounting surface attachable to the device-under-test; and an actuator coupled to the stage, the actuator also coupled to a reaction mass movable along a linear axis; a first flexure plate having a first flexure plate middle and a first flexure plate periphery, the first flexure plate middle attached to the stage at a first stage end, a second flexure plate having a second flexure plate middle and a second flexure plate periphery, the second flexure plate middle attached to the stage at a second stage end that opposes the first stage end, and a frame, the first flexure plate periphery and the second flexure plate periphery attached to the frame, wherein the first flexure plate defines a first flexure plate major surface that is substantially perpendicular to the linear axis, and the second flexure plate defines a second flexure plate major surface that is also substantially perpendicular to the linear axis.
