Position Control Methods
The position of the moving platform relative to the fixed base is typically controlled by a linear actuator of some form, whether manual, motorized, or hydraulic/pneumatic. The most common method is to incorporate a lead screw passing through a lead nut in the platform. The rotation of such a lead screw may be controlled either manually or by a motor.

Famous quotes containing the words position, control and/or methods:
“You will belong to that minority which, according to current Washington doctrine, must be protected in its affluence lest its energy and initiative be impaired. Your position will be in contrast to that of the poor, to whom money, especially if it is from public sources, is held to be deeply damaging.”
—John Kenneth Galbraith (b. 1908)
“Just as men must give up economic control when their wives share the responsibility for the family’s financial well-being, women must give up exclusive parental control when their husbands assume more responsibility for child care.”
—Augustus Y. Napier (20th century)
“A woman might claim to retain some of the child’s faculties, although very limited and defused, simply because she has not been encouraged to learn methods of thought and develop a disciplined mind. As long as education remains largely induction ignorance will retain these advantages over learning and it is time that women impudently put them to work.”
—Germaine Greer (b. 1939)
