Security barrier

Abstract

An apparatus and method for installing and deploying a barrier utilizing one or more gas generators. The invention includes a barrier component installed beneath the ground surface or substantially parallel to the ground and raised by activation of the gas generator. The device can be trigger automatically without human intervention and thereby faster deployment of the barrier. The barrier can include a reactive component. The barrier can include plurality of telescoping barrier subcomponents.

1 . A method of deploying a barrier comprising:
 a) activating a gas generator; and   b) using the expanding gas to move a barrier component from a first position to a second position wherein the barrier component consists essentially of a cylinder having a top and a mechanism to retain and lock the barrier component to another component.   
   
   
       2 . The method of  claim 1  further comprising transmitting an RF signal from a remote sensor to a gas generator activation mechanism.
