Detecting phase difference is very important in many applications, such as servo mechanisms, and demodulators.
2.
The mechanism usually includes an angular reference device such as a mechanical or optical servo mechanisms.
3.
Traverse and shell ramming were powered by electrical servo mechanisms, elevation and cartridge ramming were by hand.
4.
"It is a tiny electrical fault in the servo mechanism, " said Peter Saltzer, a Saab Autmobile press spokesman.
5.
In optical recording systems, servo mechanisms accurately follow the track in three dimensions : radial, focus, and rotational speed.
6.
One moving head accessed each data surface ( 20 total ), one more head was dedicated to the servo mechanism.
7.
A servo mechanism in the finder drove the aperture lever on the lens, stopping it down to the correct value.
8.
Lofstrom believes that this instability also can be controlled in real time by servo mechanisms, although this has never been attempted.
9.
At the same time, Quantum Corporation sued CMI for patent infringement relating to the servo mechanism in the entire CM6600 line of drives.
10.
Historically, a different operation method has been used, in which the sample-probe support distance is kept constant and not controlled by a feedback ( servo mechanism ).
