Abstract: The manipulation and control of entangled particle and entangled photon properties by means of low loss interaction free quantum means is vital for studying the fundamentals of entanglement and for future applications in distributed quantum information processing, sensing and imaging. Despite its importance, achieving low loss interaction free manipulation and control of entanglement is difficult, particularly with pulsed networked systems with quantum properties changing in space and time and with intervening absorbing elements. This invention uses low loss quantum interaction free techniques and designs that can be miniaturized to efficiently and robustly send and receive quantum information and data using pulsed and continuous origin temporal and polarization entangled particles and entangled photons. The invention may be used to improve quantum communication of information and quantum networking in fiber optics, turbulent and scattering media, and free space.

Abstract: This invention outlines a method for synthesizing a blended resin system in a one pot reaction that may utilize, for example, bio-based anhydrosugars such as isosorbide as a principle component to produce isosorbide dimethacrylate and other monomeric materials for thermosetting applications. This invention establishes a one-pot procedure for reacting a hydroxy group containing compound with methacrylic anhydride in the first step and using the by-product methacrylic acid to react with glycidyl ethers to form additional methacrylate compounds in the second step. This methodology can be formulated to produce a wide array of resin systems that have controlled ratios of hydroxy group containing compound/cross-linker/reactive diluent. Additionally, the novel resin systems may be partially to fully bio-based, promoting global sustainability and reducing costs, and when free radically polymerized have properties that meet or exceed their petroleum derived counterparts.

The substrate surface includes a substrate length edge having a substrate length and a substrate width edge having a substrate width. The polycrystalline laminate has a notch extending beyond the substrate width edge of the substrate surface. The method comprises at least one of: for tensile cleavage testing, applying a tensile load on the notch of the polycrystalline laminate in a direction generally perpendicular to the substrate surface and away from the substrate surface; and for shear sliding testing, applying a shear load on the end of the polycrystalline laminate in a length direction generally parallel to the substrate length edge of the substrate surface. A notch edge formation piece and a notch end formation piece may be used to form the laminate.

Abstract: The pocket detection platform (PDP) detects pathogens, toxins and chemicals of interest simultaneously by way of a multi-channeled, soft see-through plastic pouch design that consists of inner and outer compartments that promote compartmentalization and/or unidirectional sample flow. The platform enables the concurrent running of multiple detection assay techniques such as lateral flow immunoassays (LFI), Isothermal molecular assays (i.e., Recombinase Polymerase Amplification, or RPA) and/or paper-based chemical assays (i.e., M8, pH paper) from a single wet or dry sample with minimal sample processing. The PDP reduces soldier overburden by decreasing size weight, and power (SWaP) as well as training time, electronic burden, while providing a flexible, customizable assay platform that can be rapidly produced, assembled, sustained, and when contaminated, easily to dispose of.

Abstract: Protective coating to prevent sublimation are disclosed. More particularly, the protective coatings comprise one or more alkaline earth halide materials, or mixtures thereof, to prevent sublimation. The alkaline earth halide material of the coating can be judiciously selected to match the coefficient of thermal expansion (CTE) of the material of the external surface of the underlying substrate coated. The protective coatings may be advantageous for protecting external surfaces of thermoelectric materials, parts and devices at high temperature to prevent sublimation and material loss.

Abstract: The present system for modeling intelligent sensor selection and placement takes signal and sensor information and calculates a statistical inference. As signal data passes through a series of processors, it is transformed by functions to account for signal emission, sensor reception, environmental factors, and noise. This produces a simulation of what the emitted signal would appear to be at a given sensor. The system may be used to select the most effective sensors for a given area or to determine the best sensor coverage for a given area.

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.
