Abstract
This invention is for an accelerometer having a stack comprising both linearly responsive transducers and rotationally responsive transducers for measuring accelerations in the six degrees of freedom. Linear transducers such as lifters and tangenters can be combined in a stack with rotational transducers such as teeters and twisters which react to accelerations. Position sensors can be placed adjacent the transducers to sense their movement. When the position sensors detect a change, a current is applied to the transducer to return the transducer to its rest state. The current applied to return the transducer to its rest state is proportional to the acceleration experienced by the transducer, thereby providing a means to measure the acceleration on the transducer.
