Abstract: Components of a projectile are held together by a captive collar that is internal to the projectile. The internal captive collar is rotated about a central boss, allowing external threads on the collar to engage one of the mating components and pull that mating component into the other mating component in an axial only translation. The internal captive collar is rotated using a geared-key during assembly. This key engages a geared crown feature of the captive collar, allowing it to rotate. After assembly, the gear key is removed from the assembly. Castellated features nest within slots to transmit torque in the assembled projectile.

Abstract: Novel electrically-isolated high-voltage sensors are provided which have low power dissipation. The sensors are formed of a circuit comprising first and second portions separated by an electrical isolation boundary with the first portion used for high-voltage, and the second portion for low-voltage. While they are decoupled electrically, they are coupled both optically and magnetically. The first portion comprises an LED which generates an optical signal corresponding to a high-voltage signal across the electrical-isolation boundary. The second portion comprises a photodiode which receives the optical signal emitted from the LED and outputs a corresponding low-voltage electrical signal.

Abstract: The present invention relates novel furan based amine cross-linkers with improved thermomechanical and water barrier properties. The novelty of this invention is the use of aromatic, and hydrophobic aliphatic aldehydes to bridge two furfuryl amines, which yields a diamine or tetra amines with a significantly enhanced hydrophobic character. These diamine cross-linkers exhibit enhanced water barrier properties and thermomechanical properties when cured with both commercial and synthetic epoxies.

Abstract: The present anti-ballistic shelter is a reinforced unit configured to comply with both ISO standards for size and weight, and with the U.S. Department of State Certification Standard for Forced Entry and Ballistic Resistance of Structural Systems. Each end and side wall of the unit is reinforced with wall studs that penetrate the unit's structural framework. Even though these wail studs are welded into place, penetration of the wall studs into the framework ensures acceptable blast, ballistic, and forced entry resistance even if the welds are flawed.

Abstract: A safe and reliable multi-component projectile enables cost effective manufacturing and assembly of the projectile. Major components of the projectile are joined by a plurality of shear pins interfacing with scalloped geometry of the components. The components are then held together by forcibly joining them using a hybrid annular-cantilevered snap fit joint. The tooth and groove arrangement exists where the teeth are at the end of a spring-leaf like feature of one of the mating parts and the groove is located on the opposite mating part.

Abstract: The chilling system provides cooling to components housed within a container by pumping propylene-glycol-water-mixture (PGWM) or equivalent through heat exchange assemblies and thermal transfer vessels. The thermal transfer vessels are filled with a paraffin-based phase change material (PCM) or equivalent solution for realizing phase change of the PCMs at selected melting points. The heat exchange assemblies are provided with thermal electric coolers for cooling the PGWM as it travels through the heat exchangers. The cooled PGWM is directed into and through a target cooling manifold of a target heat exchanger assembly to realize cooling the housed components. The system operates on direct current at under 500 watts of power and requires no Freon-type refrigerants or compressors. A microcontroller controls switches for realizing desired flow paths of the PGWM upon receiving phase change and temperature information from sensors.

Abstract: A method for developing capture agents for target proteins employs a compound library to find cyclic peptide sequences that bind the target protein. The target protein is also reacted with a clickable group-provider reagent to provide the protein with clickable groups. The compounds in the library are provided with complementary clickable groups that bind the clickable group on the target protein when the peptide sequences bind the target protein. In some embodiments, the cyclic peptide sequences that bind the target protein are incorporated into constructs having one or more arms that can serve as capture agents or potential treatments against the pathogens from which the target protein is derived. Some embodiments provide pharmaceutical compositions for immunoassays, diagnostics, therapeutics or the like, that employ the constructs.

The delay element or delay elements each have an input charge, a delay composition, and an output charge. Both the input charge and the output charge are igniter compositions and are comprised of the same components despite having different functional goals. The input charge and output charge compositions preferably contain titanium, manganese dioxide, and polytetrafluoroethylene. The delay composition may be modified from current formulations to include manganese and manganese dioxide, or tungsten and manganese dioxide. The system disclosed herein may be comprised of one delay element, or it may be modular wherein multiple delay elements are connected in series.

The airborne delivery system is configured to be mounted on a JPAD, or similar airborne platform. As with a conventional JPAD, the JPAD is then released from an airborne vehicle. After a certain amount of flight time, one or more UAVs are released mid-flight from the airborne delivery system.

Abstract: A system and method for distributed wireless communications comprising a first group of agents selected and configured to wirelessly transmit a communication signal to a client, wherein the first group of agents is capable of forming a radiation beam carrying the communication signal vectored substantially toward the client, and a second group of agents selected and configured to wirelessly broadcast communication signal interference, wherein the second group of agents is capable of forming a radiation beam not vectored substantially toward the client. Consequently, the first group of agents securely communicates with the client and the second group of agents suppresses the ability of an unauthorized, eavesdropping receiver from intercepting the communications signal.
