Abstract: An adjustable sight assembly for attachment to a firearm is provided. A base with a recessed portion has a plate that loosely fits within the recessed portion. A windage adjustment assembly cooperating with the base and a first end of the plate i) effects side-to-side movement of the plate within the recessed portion of the base, and ii) defines a pivotal coupling of the plate to the base at the first end thereof. A second end of the plate moves along an arc when the plate is pivoted about the first end thereof. An elevation adjustment assembly cooperating with the base and the second end of the plate effects elevation of the plate's second end. A sight is pivotally coupled to the plate such that the sight can lie against the plate when not in use and can be rotated approximately 90° to extend vertically from the plate when in use.

Abstract: The present invention controls the polar ejection angle of fragments in a fragmenting warhead. The warhead's detonators are initiated non-simultaneously to produce corresponding detonation waves in the warhead's explosive material. The detonation waves interact to control the polar ejection angle of fragments formed when the warhead's casing ruptures. Specified times of detonation for each of the detonators can be selected/adjusted after the warhead is deployed.

Abstract: A warhead casing defines a geometry that is a portion of a ring having an outer radial wall and an inner radial wall spaced radially apart from one another. The outer radial wall and inner radial wall are joined radially by side walls, while the casing is enclosed at either axial end thereof by end walls. An explosive material fills the casing. At least one initiator is positioned in the explosive material along a radial plane that bisects the portion of the ring. Detonation of the explosive material causes the inner radial wall to form an EFP while the outer radial wall fragments.

Abstract: A water-activated locking mechanism has a housing with a chamber formed therein. Compressed water-absorbent fiber pellets are housed in the chamber. Ports in the housing allow water to enter the chamber when the housing is immersed in water. Mounted in the housing is a slidable piston assembly that is biased towards the chamber with a first end of the piston assembly residing in the chamber.

Abstract: An epitaxial barrier material provides not only a unique growth medium for growing single crystal structures of elemental metal thereon, but also provides an effective diffusion barrier at extremely thin thicknesses against migration of atoms from the metallization layer into an adjacent semiconductor substrate or low dielectric insulation layer. This invention is particularly advantageous for forming single crystal, transition metal conductor lines, contacts, filled trenches, and/or via plugs, and especially conductor structures based on transition metals of copper, silver, gold, or platinum. These metals are highly attractive for interconnect strategies on account of there respective low resistivity and high reliability characteristics. Processes for making the barrier film in a semiconductor device are also covered.
