ABSTRACT:
A teeter-totter apparatus uses a curved beam to generate a differential output which may be indicative of an acceleration applied to the apparatus. The curved-beam teeter-totter apparatus can be combined with an x-axis and y-axis accelerometer, to produce a tri-axis accelerometer which is sensitive to an acceleration applied in any direction. Damping plates may be added to the accelerometers to reduce unwanted motion.
