Angular velocity and time derivative of angular displacement
American Journal of Physics, 1986It is shown that, given the angular displacement vector Φ(t)for a rigid object, the angular velocity can be found by rotating dΦ/dt about Φ through angle 1/2 Φ and decreasing the component perpendicular to Φ by (1/ 1/2 Φ)sin 1/2 Φ. The result is illustrated by considering a regular precession at a fixed angle with the vertical.

Vibration type angular velocity sensor
The Journal of the Acoustical Society of America, 2006To cancel in-phase components acting on vibrators of first and second sensor units in an angular velocity sensing direction Y, a differential amplification circuit obtains a differential waveform between a first angular velocity sensing waveform J1 and a second angular velocity waveform J2.

Angular Velocity and Acceleration
2015In this chapter, a complete characterization of the angular velocity and angular acceleration for rigid bodies in spatial multibody systems are presented. For both cases, local and global formulations are described taking into account the advantages of using Euler parameters.

Digital measurement of angular velocity
Journal of Physics E: Scientific Instruments, 1973A new approach to the digital measurement of angular velocity is presented. A special optical transducer is described which provides the necessary pulse rate. The time between the pulses is measured and the division by time is achieved by a simple digital processor.

Damage detection using angular velocity
2019<p>The present work introduces novel methodologies for damage detection and health monitoring of structural and mechanical systems. The new approach uses the angular velocity inside different mathematical forms, via a gyroscope, to detect, locate, and relatively quantify damage.
