It is an ancient example of a differential motion.

Control was by differential motion of the wings; the tailfins were fixed.

Differential motion forces the interleaved discs to move through the fluid against each other.

This may result in differential motion, and the creation by the iceberg of an open water track through the pack ice.

Differential motion along the zone produces numerous earthquakes, the foci of which may be as deep as about 670 kilometres.

These are connected so that differential motion of the lines rotates the bellcrank, causing a pushrod to move either forward or aft.

If the gas or liquid is very viscous (resulting in turbulent differential motion), the reversal of the magnetic field may not be very periodic.

When the forward element is deflected, the mechanical linkage causes the desired differential motion between the forward and aft element assembles.

Dipole studies, least-squares fitting of predicted and observed peculiar velocities and the analysis of the covariance tensor of reconstructed differential motions give, and, respectively.

It is this type of differential motion that allows the iris to be positioned in any area of the optical axis in the lens, and do it in the smallest possible space.

The PS Technique is a remote sensing technology capable of accurately supplying the differential motions of million of "natural radar targets" (the PS) distributed on the earth’s surface.

On this basis, it is proposed that adaptation has a functional basis in improving temporal resolution and transmitting differential motion information, thus increasing the effective bandwidth of the motion pathway in the optokinetic system.
