Abstract

See full text

An acceleration measurement system is provided. The system includes at least first and second accelerometers. The first accelerometer has an electrical characteristic that varies with acceleration in a first axis. The second accelerometer also has an electrical characteristic that varies with acceleration in the same first axis. A controller is operably coupled to the first and second accelerometers and provides an acceleration output that is based on the electrical characteristics of the first and second accelerometers. In one aspect, the acceleration system is in the form of a substrate-like sensor.
