ABSTRACT:
An apparatus having an arrangement of two or more identical accelerometers with aligned sensitivity axes. Each of the accelerometers senses motion over at least one axis. The accelerometer readings include a component corresponding to gravitational force that is the same for each accelerometer in the arrangement. Logic circuitry in communication with the accelerometer arrangement couples accelerometer signals to a processor to compute motion variables.
