Patent ID: 8276518

Claim:
A decoy for an infra-red radiation seeking device that comprises: a) an anchoring body; b) two or more bundles of pyrophoric elements; c) straps that bind at least two of the bundles to the anchoring body; and d) two or more pyrophoric bodies, wherein each pyrophoric body heats up upon exposure to air and melts or burns at least one strap that binds at least one bundle to said anchoring body thereby causing said at least one strap to break or fail resulting in the sequential release of said at least two bundles from said anchoring body and from said decoy after said decoy has been released from a target, wherein: (i) said two or more bundles of pyrophoric elements comprise a first bundle and a second bundle that are bound to said anchoring body by said straps; and (ii) said first bundle is released from said decoy before said second bundle and said first bundle is released from said decoy at a position that is closer to said target than the position at which said second bundle is released from said decoy, further wherein; (a) each of the bundles forms a cloud of pyrophoric elements shortly after release from the decoy and said cloud of pyrophoric elements produce infra-red radiation; and (b) at least some of the pyrophoric elements comprise a pyrophoric coating on a supporting body, said pyrophoric coating containing at least one pyrophoric powder and a binder.
