Active Systems
In these systems the change in attitude of the binoculars is sensed electronically, and some part of the system is changed to correct this offset. A lens group may be shifted, or the angle of a fluid filled prism may be changed.

Famous quotes containing the words active and/or systems:
“This teaching is not practical in the sense in which the New Testament is. It is not always sound sense in practice. The Brahman never proposes courageously to assault evil, but patiently to starve it out. His active faculties are paralyzed by the idea of caste, of impassable limits of destiny and the tyranny of time.”
—Henry David Thoreau (1817–1862)
“Our little systems have their day;
They have their day and cease to be:
They are but broken lights of thee,
And thou, O Lord, art more than they.”
—Alfred Tennyson (1809–1892)
