(under subclass 503) Subject matter wherein the means for determining speed by integrating time and acceleration comprises a wheel or a disc mounted to spin rapidly about an axis of spin and also free to rotate about one or both of two axes perpendicular to each other and to the axis of spin so that a rotation of one of the two mutually perpendicular axes results from the application of torque to the other when the wheel is spinning.
