An adapter device is provided for converting a grenade launcher into a weapon for firing shot shells. The adapter includes an elongate barrel member of a gauge for shot shell which is adapted to be received in, and extend through, the barrel of the host barrel assembly of the grenade launcher.
A method for measuring the complex frequency-dependent dilatational and shear wavespeeds of a slab of material subjected to insonification. Transfer functions that are obtained by insonifying the material at different angles.
A structural member of a mortar projectile is inspected. The structural member is a composite structure having a thermoplastic matrix with a filler of steel balls. The composite structure has a central cavity into which is placed a strobe light.
A reconfigurable antenna is presented that uses MEMs shutters to reconfigure a Fresnel zone plate antenna. It can be used to either point a main beam in different directions or to point multiple beams in different directions.
A segmented patch antenna has a dielectric material substrate, a plurality of primary electrically conductive segments consecutively disposed on the dielectric material substrate and spaced apart so that a portion of the substrate is exposed between any pair of adjacent primary segments, and a la
A permanent magnet assembly, for engaging a generally planar surface of a ferromagnetic object to affix items of interest thereto, includes a shell of a magnetic material.
A spectrum analyzer includes a resonator board that in turn has a substrate and a plurality of resonators. Each resonator may include a first segment that includes a first segment discontinuity and that may also define a boundary and a second segment that has a second segment discontinuity.
The present invention is a modified darlington phototransistor wherein a phototransistor is coupled to a Bipolar Junction Transistor (BJT). This design provides a high sensitivity and a fast response and effectively increases the gain of the photocurrent.

A filter-testing fixture holds a single fuel filter and is adjustable to accommodate a range of filter sizes and shapes. The fixture has a base section that defines a water collection reservoir, and the base opens upward toward a housing.
In this application is described the expression and purification of a recombinant Plasmodium falciparum (3D7) AMA-1 ectodomain. The method of the present invention produces a highly purified protein which retains folding and disulfide bridging of the native molecule.
The invention provides a method for the aerial transfer of munitions from a rearming aircraft to the weapons pylon of the recipient combat aircraft. The invention also provides for the selection of munitions from a database of munitions and aircraft types in response to an Air Tasking Order.
A hollow elliptical-cylindrical hull conformingly houses a hollow rectangular-prismatic cabin whereby the four longitudinal parallel outside edges of the latter make contact with the inside surface of the former.
A steering system is provided for a hydrodynamically shaped vehicle having a nose end, a tail end, and forward propulsion.
A propelling charge support comprises horseshoe-shaped clips for engaging the tail fin and holding the propelling charges together for protection, a rounded saddle for holding the propelling charges of the cartridge, and winged edges to protect the propelling charges and aid in removal of the pro
Molten droplets of a metal fuel, such as aluminum, are dispersed into air or water for a reaction releasing energy for military or other purposes.
An elongate ballistic protection apparatus is described and claimed herein which has minimal weight and maximum flexibility to conform to the most contorted and undulating ground surfaces.
An invariant checking method and apparatus using binary decision diagrams (BDDs) in combination with constraint solvers for determining whether a system property is an invariant of a system description.
A predictor for optimal transducer power gain computes the maximum transducer power gain attainable by a lossless matching network for a given load operating over selected non-overlapping (disjoint) sub-bands within a frequency band of operation.
A knowledge-based condition survey inspection (KBSCI) framework and procedure for use with an engineering management system (EMS) that tailors types of condition survey inspections (CSIs) and inspection intervals to empirically-established life cycles of component-sections.
