Abstract From the Canadian patent

Inertial measurements including the measurement of, angular velocity as well as angular and translational acceleration, are made by spinning one or more translational acceleration transducers disposed at a point on a spinning member with the sensitive axis of at least one of the transducers substantially parallel but not coincident with the spin axis of the spinning member and combining their output signals. The principles of the invention are also applied to generate components of translational acceleration for the purpose of calibrating translational acceleration transducers.
