A lightweight ring with two notches for the axle ends rests in the groove. This ring can slip in the groove, allowing the ball to spin perpendicular to the rotational axis of the ring. To increase the angular velocity of the ball, the sides of the groove exert forces on the ends
Daisuke Matsuzaka: Familiar with the gyroball, Matsuzaka has stated that he can throw the gyroball, however cannot do so on a consistent basis.A careful computer analysis of Matsuzaka's pitches for the Boston Red Sox for the first half of the 2007 season by Dan Fox of Baseball Prospectus suggests that while Matsuzaka commands a dazzling array of pitches, the gyroball is more myth than reality.
Multi-Axis Trainer at the Euro Space Center. An aerotrim (also known as Multi-Axis Trainer or MAT) is a 3-axis gimbal large enough to contain a human being, used for cardiovascular workout and equilibrioception (balance) training in pilots and astronauts.
The turn indicator is a gyroscopic instrument that works on the principle of precession.The gyro is mounted in a gimbal.The gyro's rotational axis is in-line with the lateral (pitch) axis of the aircraft, while the gimbal has limited freedom around the longitudinal (roll) axis of the aircraft.
Vacuum system using a vacuum pump Vacuum system using a venturi. The heart of the AI is a gyroscope (gyro) that spins at high speed, from either an electric motor, or through the action of a stream of air pushing on rotor vanes placed along its periphery. The stream of air is provided by a vacuum system, driven by a vacuum pump, or a venturi.
A control moment gyroscope (CMG) is an attitude control device generally used in spacecraft attitude control systems. A CMG consists of a spinning rotor and one or more motorized gimbals that tilt the rotor’s angular momentum.

A critical requirement for accuracy is low static friction in the bearings of the pendulum; this is achieved by various means ranging from double ball bearing with a superimposed oscillatory motion to dither the bearing above its threshold or through the use of gaseous or fluid bearings or by the alternative method of floating the gyroscope in ...
