Since 2012 FOI group LLC has primarily performed consulting work on a new type of shaped charges for a partially owned company Innovative Defense LLC. The perceived value of these inventions is evident by this focus.
This patent discloses a novel shaped charge device that produces a hollow cylindrical jet capable of creating a hole in a target larger than the overall diameter of the device.
Abstract: A novel shaped charge device that produces a hollow cylindrical jet capable of creating a hole in a target larger than the overall diameter of the device. In the conical family of axisymmetric circular linear shaped charge liners (Conical, Tulip, and Trumpet), this novel swept conical-like profile shaped explosive device produces a large diameter stretching hollow cylindrical jet and corresponding slug. The hollow jet is formed by peripherally initiating a high explosive (HE) that collapses the circular linear liner into the hollow cylindrical jet. The precision of the circular simultaneous peripheral initiation of the HE billet is accomplished by the use of a novel Circular Precision Initiation Coupler (CPIC). This CPIC uses a single point initiation to create a simultaneous peripheral detonation of the HE billet that collapses and drives the swept liner into a high speed stretching hollow cylindrical projectile, or more commonly called a jet in the industry.

This patent discloses a novel axisymmetric revolved arc explosively formed projectile (REFP) shaped charge design will produce a projectile that is greater than 2/3 the diameter of the device forms a hole larger than the device diameter and removes all of the target material within the hole diameter.
Abstract: This novel axisymmetric revolved arc explosively formed projectile (REFP) shaped charge design will produce a projectile that is greater than 2/3 the diameter of the device forms a hole larger than the device diameter and removes all of the target material within the hole diameter. The precision of the circular simultaneous initiation of the HE billet is accomplished by the use of a novel Circular Precision Initiation Coupler (CPIC). This CPIC uses a single point initiation to create a simultaneous peripheral detonation of the HE billet that collapses and drives the revolved liner into a large diameter double wall hollow cylindrical explosively formed projectile.

This patent discloses an enhanced light weight armor plating for protection against HEAT warheads.
Abstract: A light weight armor system for retrofitting onto a light vehicles or incorporating into a vehicle to protect against HEAT warheads. The armor system comprises an outer armor structure for rotating a HEAT warhead toward a preferred detonation angle to maximize the protection of underlying armor or vehicle structures. This first armor structure will further impart a rotational movement to increase the energy impact footprint, dissipate jet stream energy, and improve the probability that a second protection layer can successfully resist penetration by the jet stream. Coatings on the armor structure materials laterally impact a HEAT jet stream to further disrupt the jet and dissipate its energy. Read more...
