Abstract
A micro-gyro device is disclosed combining an element which oscillates around the drive axis and an element which rocks around the output axis, so arranged that Coriolis force is transmitted from one element of the other without any substantial transfer of motion of either element to the other in its own direction of motion. In other words, the masses of the two elements operate independently of one another, providing improved performance, and individual adjustability to compensate for any manufacturing imprecision. The presently-preferred device combines an outer ring which oscillates around the drive axis with an inner disk which rocks around the output axis, whenever external rotating motion occurs about the rate axis.
