The arm is the horizontal distance from the reference datum to the center of gravity (CG) of an item. The algebraic sign is plus (+) if measured aft of the datum or to the right side of the center line when considering a lateral calculation.
Joint IED Neutralizer (JIN): In 2005, Ionatron attempted to develop an anti IED device that would "zap" IEDs from a distance by using lasers to ionize the air and allow man-made lightning to shoot towards the devices detonating them at a safe distance. By using femtosecond lasers light pulses that last less than a ten-trillionth of a second JIN ...

The minimum standoff distance or minimum safe distance is the minimum distance from the explosive charge the breachers must be to avoid serious injury from overpressure. The minimum standoff distance is calculated based on the amount and type of explosive placed and is used to ensure that breachers do not experience greater than 4 psi (28 kPa ...
Range safety at Europe's Spaceport is the responsibility of the Flight Safety Team, [19] with the launch site and surrounding areas being safeguarded by the French Foreign Legion. [20] The earliest Ariane 5 rockets were controlled by flight computers with the capability to terminate a flight by own initiative , including the infamous Ariane 501 ...
They are equipped with linear demolition charge system (LDCS): rockets carrying C-4 explosives up to 100–150 yards forward, detonating hidden explosives at a safe distance, so that troops and vehicles can pass through safely. [2]
The Mk 19 can launch its grenade at a maximum distance of 2,212 meters (2,419 yd), though its effective range to a point target is about 1,500 meters (1,600 yd), since the large rear leaf sight is only graduated as far. The nearest safe distance to launch the grenade is 310 meters in training and 75 meters in combat.
Radar separation is applied by a controller observing that the radar returns from the two aircraft are a certain minimum horizontal distance away from each other, as observed on a suitably calibrated radar system. The actual distance used varies: 5NM (9.26km) is common in en route airspace, 3 NM is common in terminal airspace at lower levels.
