Patent ID: 8371224

Claim:
A variable yield device, comprising: an energetic charge; a guide; a main charge; a main detonator; an energetic detonator; housing structures; a booster charge being disposed between the main charge and the main detonator; and a control unit, wherein the energetic charge and the guide are operatively joined to each other, wherein the guide and the main charge are operatively joined to each other, wherein the energetic detonator is operatively connected to the energetic charge, wherein the main detonator is operatively connected the main charge, wherein the control unit is operatively connected to both the energetic detonator and the main detonator and configured to vary, selectively a yield of the device, wherein the guide is a hollow guide, wherein the guide includes a proximal end adjacent the energetic charge and a distal end adjacent the main charge, and wherein the energetic charge, the main charge and the booster charge are enclosed in the housing structures.
