  • Patent number: 10677567
    Abstract: A transparent composite armor is made of tens to hundreds or even thousands of thin layers of material each with a thickness of 10-500 ?m. An appropriate amount of impedance mismatch between the layers causes some reflection at each interface but limit the amplitude of the resulting tensile wave below the tensile strength of the constituent materials. The result is an improvement in ballistic performance and that will result is a significant impact in reducing size, weight, and volume of the armor.

  • Patent number: 10676445
    Abstract: A new azido compound, 5-amino-6-chloro-2,4-diazido-pyrimidine, and a process for synthesizing. The synthesis may include reacting 5-amino-2,4,6-trichloropyrimidine and sodium azide. There is an excess molar amount of sodium azide for each chloro fractional molar amount on the 5-amino-2,4,6-trichloropyrimidine. The synthesis is a two phase reaction that is a dispersion. The 5-amino-2,4,6-trichloropyrimidine dissolved in acetone is a liquid phase, and the sodium azide is insoluble in acetone and is a solid phase, that is present in excess of chemical equivalents. The reaction product is soluble in acetone, and the reaction by-product, sodium chloride is also insoluble in acetone, and the crude yield is about 92%. Unreacted sodium azide and formed sodium chloride are removed by filtration.

  • Patent number: 10672933
    Abstract: A new approach to graphene-enabled plasmonic resonant structures in the THz is demonstrated in a hybrid graphene-metal design in which the graphene acts as a gate-tunable inductor, and metal acts as a capacitive reservoir for charge accumulation. A large resonant absorption in graphene can be achieved using the metal-graphene plasmonic scheme, and the peak can approach 100% in an optimized device, ideal for graphene-based THz detectors. Using high mobility graphene (?>50000 cm2V?1s?1) will allow anomalously high resonant THz transmission (near 100%) through ultra-subwavelength graphene-filled metallic apertures at a resonance frequency that is gate tunable. This metal-graphene plasmonic scheme enables near perfect tunable THz filter or modulator.

  • Patent number: 10663614
    Abstract: A magnetic anomaly sensing system and method uses two triaxial magnetometer (TM) sensors arranged in a one-dimensional array with the sensors' magnetic sensing axes being parallel to one another. The sensors are spaced-apart from one another along one of the sensing axes by a distance D with a midpoint between the sensors along the one sensing axis being located a distance Z from a reference datum. A processor implements an iterative process to include generating scalar magnitudes of a magnetic anomaly field measured at each of the sensors where the magnetic anomaly field is associated with a magnetic object. A scalar range from the sensors to the magnetic object is generated based on the distance D, the distance Z, and the scalar magnitudes. A magnetic dipole moment of the magnetic object is generated using the scalar range and the scalar magnitudes.

  • Patent number: 10663666
    Abstract: This invention is a method and system for addressing structural weaknesses and geometric differentials introduced to a cable when splicing optic fibers. The apparatus and method utilize structurally integrated layers of protective polymers and bonding materials selected for strength and flexibility relative to their thickness. This results in an apparatus having a minimally increased circumference compared to the cable. The method and apparatus include one or more strengthening layers which allow the repaired cable substantially similar flexibility compared to the cable, but prevent formation of sharp bends or kinks. The strengthening layers also allow the repaired cable a resistance to tension similar to the original cable. The method and apparatus further include an outer layer having a geometric configuration which includes sloped terminating ends designed to prevent the reinforced area of the cable from being damaged by the force of objects or substances in contact with cable.
