Patent ID: 7191707

Claim:
An explosive ordnance device, comprising: a substantially spherical shaped structure having a hard outer shell, the combination of which is adaptable to rolling on a surface; the spherical shaped structure further having a hollow inner core symmetrically disposed about an axial center of the structure; a periphery of the hollow inner core having a shock absorbing layer; the hollow inner core having within it a plurality of mutually orthogonal motion sensors rigidly attached to the core; the plurality of mutually orthogonal motion sensors being electrically coupled to a computing device for accepting outputs of the sensors in order to compute motion profile samples; the computing device being rigidly attached to the core; an explosive charge being distributed between the shell and the core; a fuse mechanism disposed within the explosive charge, and being electrically coupled to a primary arming device; the primary arming device being armed responsive to predetermined criteria of the motion profile samples processed by the computing device; wherein when the primary arming device is armed, the fuse is ignited to provide detonation of the ordnance device.
