Abstract: The present invention provides an initial strike-face layer for armor, a method of constructing an armor plate and armor. In one embodiment, the initial strike-face layer includes a substantially planar surface having a relief pattern with raised or recessed structures, each of the structures having sides that are oblique to the substantially planar surface.

Abstract: The present techniques provide a method for making wear surfaces comprising a thermoplastic matrix blended with ceramic particles. The wear surfaces may optionally contain other materials, such as friction modifying additives. Wear surfaces formed according to these techniques may be used to protect such surfaces as the side rails of conveyor belts, the teeth of buckets used on front end loaders, rock or debris chutes, and self dumping hoppers, among others.

Abstract: The present techniques include a field armor system comprising hollow structures designed to be filled with field materials, such as soil, sand, rocks, or clay. At least one face of the structures is made from a projectile resistant plastic composite. The projectile resistant plastic composite panel may be made from a ceramic plastic composite, a fiber plastic composite, or interspersed layers of both. In one embodiment, the hollow structure comprises four connected panels that may be collapsed when empty. In another embodiment, the hollow structure may comprise hollow bricks designed to interlock to form a protective wall.

Abstract: The present invention provides for a heat sink that, in a particularly advantageous embodiment, includes a heat sink body with a spine configured to be oriented parallel with the direction of air flow when the heat sink is coupled to a substrate. The heat sink further includes a first set of cooling fins that are coupled to and extend from the spine along a first common longitudinal axis. At least two of the first set of cooling fins laterally extend from the first common longitudinal axis in a common direction and in an offset relationship to each other.

Abstract: The present invention provides a heatsink for use with a heat-generating electrical component. The heatsink comprises a spine having opposing sides, cooling fins extending from the spine, and a dielectric layer adhered to at least one of the opposing sides. The dielectric layer has a thermal conductivity of at least about 1 W/m° C. The heatsink may further comprise a metal layer adhered to the dielectric layer. The metal layer provides a surface to which an electric component can be adhered. The heatsink can further include a heat-generating component adhered to the metal layer. In another aspect, the heat-generating component is a surface-mount electrical component adhered to the metal layer with solder.

Abstract: An optical rotary joint has a first pair of light beam expanding graded index (GRIN) of refraction lenses coupled to ends of a first pair of lightguide fibers for coupling signals through the rotary joint interface in a first path which is coaxial with the axis of rotation in the interface. A second pair of lightguide fibers are coupled to a second pair of GRIN lenses off-axis and of much smaller diameter than the lenses of the first pair. Prisms couple signals between the off-axis lenses and a second path across the interface and which is also coaxial with the axis of rotation. Also shown is a method for compensating for lens irregularities.
