Angular velocity sensor and angular velocity detector
The Journal of the Acoustical Society of America, 2008The present invention provides a cheap angular velocity sensor capable of detecting angular velocity with high precision by using a vibration mode which cannot be set by external vibration. The angular velocity sensor includes: a vibrator ( 2 ) formed as a solid of revolution and made of a magnetostrictive material; a supporter ( 3 ) disposed on an ...

The model is developed as the steady magnetohydrodynamic (MHD) flows with an angular velocity between parallel porous plates are considered. The problem is solved analytically by using similarity transformation, whose solution deals with increasing fluid

The Angular-Velocity Distribution in Stars [PDF]
, 2012 Stars formed out of an interstellar cloud contain a certain amount of angular momentum, which is distributed over the stellar mass. Suppose there were no transport of angular momentum between the mass elements during the formation and evolution of the stars; one would then have local conservation of angular momentum, $$ \frac{{d({s^2}\omega )}}{{dt}

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.

Angular velocity optical sensor
SPIE Proceedings, 2006Most of the investigations that exist about the interferometer of Sagnac in our days, are made through fiber optic, which has the great advantage of having a big area size in very little space wound in a nucleus. The first interferometers of Sagnac, were used for very big angular speeds measures, it didn't have the advances to carry out detections of ...

Measuring average angular velocity with a smartphone magnetic field sensor
, 2018The angular velocity of a spinning object is, by standard, measured using a device called a tachometer. However, by directly using it in a classroom setting, the activity is likely to appear as less instructive and less engaging. Indeed, some alternative

An angular velocity detector includes an angular velocity detecting element having a vibrating body arranged in a base substrate to be vibrated on a surface horizontal with respect to the base substrate. The angular velocity detecting element detects an angular velocity around an axis perpendicular to the base substrate based on a vibration of the ...
