Abstract: Methods and apparatuses are provided that compensate for the polarization dependent loss (PDL) of fiber-optic quantum channels. Compensation is accomplished by inserting a compensating PDL into another quantum channel carrying entangled photons that are entangled with photons in the first channel having losses that are to be compensated for. By selecting the optimum magnitude and orientation for the compensating PDL, compensation for the PDL in the first channel is maximized.

Abstract: A passive thermal oscillator combines a thermoelectric device and a passive analog electrical circuit to produce a time-oscillating temperature difference. The oscillator makes use of a temperature difference imposed across a thermoelectric device to produce a Seebeck voltage to periodically trigger electrical current to pass through a switch. The periodic electrical current causes periodic Peltier cooling producing a time-oscillating temperature difference across the thermoelectric device. There is no requirement for additional external energy input because the thermal energy generates a voltage that is used as the driving force. The operation is purely passive. So long as there is a temperature difference across the thermoelectric device, then the passive thermal oscillator oscillates. The passive thermal oscillator can integrate multiple energy conversion device technologies to operate cooperatively.

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: A novel adaptive armor system includes an array of armor elements, a hinge system, an actuator mechanism, and a tension support. The hinge system permits rotation of the armor elements about respective axes to change their orientation with respect to the vehicle body. The tension support is movably coupled between the actuator mechanism and the array and bears at least some of the weight of the armor elements in tension. The actuator mechanism moves the tension support (e.g., under the control of a controller) to change the angular orientation of at least some armor elements. Each armor element can include a tray that removably receives different ERA cassettes therein. An exemplary method includes detecting an incoming threat projectile, assessing at least one characteristic specific to the projectile, and changing the angular orientation of the array in a manner to defeat the incoming projectile. The invention provides threat adaptability while minimizing added weight and vehicle size.

Abstract: A permeation cell device includes a body component, a wire mesh support structure positioned in the body component, a membrane over the wire mesh support structure, a pair of compressible gaskets sandwiching the membrane, and a flange compressing the membrane. A spectroscopic device contains the permeation cell device.

The permeation cell device and the spectroscopic device may collectively create a pair of separate isolated compartments. The body component may include a material that is non-permeable to the fluid.

Abstract: This invention relates generally to a chitosan-graphene oxide membrane and process of making the same. The nanocomposite membrane can filter water and remove contaminants without fouling like other commercially-available polymer-based water filters. The membrane can be used as a flat sheet filter or can be engineered in a spiral filtration module. The membrane is scalable and tunable for many water contaminants including pharmaceuticals, pesticides, herbicides, and other organic chemicals. The membrane uses chitosan, which is low-cost, renewable biopolymer typically considered to be a waste product and the second most abundant biopolymer on Earth, thus making the membrane an environmentally-friendly product choice.

Abstract: A process for producing a metal foam. The process includes mechanically working a metallic powder such that oxide particles and/or dissolved oxygen are finely dispersed within a metallic matrix of the metallic particles that make up the metallic powder.

Abstract: A polymer layering process that encapsulates and protects electronics components with complex and imprecise geometries. The protective layering process provides a combination of a flexible mold and/or a rigid mold that apply close-forming, encapsulating the polymer layers to the electronic components and precision assemblies. Polymer layer protective jackets are shaped to as-populated circuit boards and assemblies, providing tightly fit barriers with fine resolution accommodating imprecise geometries. The protective jackets can be formed in rigid, semi-rigid, or highly flexible polymer films, to protect the circuitry from the elements, CTE mismatches, shock and vibration loads and extreme g-forces, and external electromagnetic emissions. By altering the protect layer configuration, the protective layer can accommodate populated circuit board assembly with high heat generation component(s).
