A door breach training system comprising a first restraint assembly connecting a door to a frame. The door is attached to a lock jamb of the frame with a first restraint assembly that exposes a shear joint to impact from a projectile, such as shotgun round. Another embodiment further comprises attachment of the door to the hinge jamb with at least one second restraint assembly that functionally simulates a typical door hinge and exposes a shear joint to impact from a ballistic round. The preferred embodiment includes replaceable lock panels and hinge panels that are designed to break in a known manner in order to replicate those same failure modes for both door locks and door hinges in typical residential and commercial construction environments.       Recently Added Patents Driving device and driving method of plasma display panel, and plasma display apparatus Memory system and method of data writing and reading in memory systems Catalytic reactor Automatic transmission system and hydraulic control device and method thereof Method and device for merchant authentication Shoe upper Field adjustable grid intersection clip   Randomly Featured Patents Method and system for calibrating a motor control circuit to improve temperature measurement in an electrical motor Substituted piperazines Luminescence device and display apparatus Cylinder head gasket Handbag Memory cell data output circuit having improved access time Catalytically increasing the obtainable concentration of halogen in water Transmission clutches with fully-resetting modulator-load-piston Dielectric isolation of metallic conduits High level synthesis method, thread generated using the same, and method for generating circuit including such threads © 2006-2008 PatentGenius.
