Robert M Boysel, Jeffrey B Sampsell: Digital flexure beam accelerometer. Texas Instruments Incorporated, Charles A Brill, James C Kesterson, Richard L Donaldson, April 26, 1994: US05305640 (198 worldwide citation)

Acceleration is measured using an array of micro-machined elements. The array is configured so each successive element is deflected by a higher acceleration. For each acceleration there will be a set of elements that is deflected. By determining the transition point between deflected and undeflected ...
