Patent ID: 7752952

Claim:
A method for establishing and operating a dynamic barrier system comprising: deploying into a barrier area a plurality of first projectiles, each-first projectile including a sensor and not containing any lethal or otherwise intentionally harmful payload, which first projectiles are deployed in a two dimensional array forming rows and columns, with alternating rows offset vertically by one column, such that the projectiles in each row align linearly with the projectiles in every other row of the array, and wherein the detection zone of the sensor within each projectile overlaps with the detection zone of the sensors of at least two other projectiles, which first projectiles are deployed by being fired from a barrel; monitoring the barrier area using the sensors of the first projectiles; detecting an object within the barrier area, which detection is enhanced by the overlapping detection zones; deploying at least one second projectile into the barrier area by firing the second projectile from a barrel, the second projectile including a warhead and at least one sensor; determining a type of object using the at least one sensor in the second projectile; and detonating the warhead in the second projectile.
