Military Application
The ALE-39 countermeasures system uses intervalometers manufactured by Ledex Inc. (now part of Johnson Electric) of Dayton, Ohio. The ALE-39 can fire flares in a synchronized pattern, very rapidly and with great reliability. The intervalometer used in the ALE-39 is essentially a solenoid-actuated rotary switch driven by a separate programmer which gives timing intervals and channel enabling to either of one or two channels. Intervalometers that contain internal interval clocks include the Lau-68, Suu-13 and similar electromechanically sequenced switches. Safety is provided to unfired outputs by maintaining a ground connection to all except the output being selected for firing; i.e., providing an electrical pulse to the firing squib.
Bomber aircraft can release all of their bombs at one time ("salvo") or drop individual bombs at intervals. If the bombardier selects the latter, he can program an intervalometer to control the pace at which the bombs are released. This, of course, determines how far apart they will land in the target area.

Famous quotes containing the words military and/or application:
“Stately as a galleon, I sail across the floor,
Doing the military two-step, as in the days of yore.”
—Joyce Grenfell (1910–1979)
“My business is stanching blood and feeding fainting men; my post the open field between the bullet and the hospital. I sometimes discuss the application of a compress or a wisp of hay under a broken limb, but not the bearing and merits of a political movement. I make gruel—not speeches; I write letters home for wounded soldiers, not political addresses.”
—Clara Barton (1821–1912)
