Abstract
A liquid crystal flat panel monitor is mounted in a frame that is positioned in an overhead compartment of an aircraft. A D.C. motor is mounted for pivoting the monitor. A voltage source having positive and negative polarity controls the D.C. monitor causing it to pivot the monitor to a viewing position or to a stowed position. The D.C. motor carries a flywheel on its shaft that stores energy as the motor rotates. During power loss, a controller sends a voltage pulse to the D.C. motor to spin it at high speed and store enough energy in the spring flywheel to pivot the monitor to a stowed position. A deployed position switch senses when the LCD monitor is fully rotated to its open view position. An electromagnetic latch keeps the LCD monitor locked in its stowed position until it is to be displayed for viewing.
