G01P3/00	Measuring linear or angular speed; Measuring differences of linear or angular speeds (G01P 5/00-G01P 11/00; take precedence;measuring angular rate using gyroscopic effects G01C 19/00)
	Note(s) Groups G01P 3/02-G01P 3/64 are distinguished by the method of measurement which is of major importance. Thus the mere application of other methods for giving a final indication does not affect the classification.
