ABSTRACT: We propose to develop a light weight, compact, vibration-less and micro-scale cooler for space-mission conditions based on optical refrigeration using an all-fiber approach. Specifically, we will use a Tm+3-doped fiber laser to pump Tm+3-doped glass fibers, which provide the cooling action on the affixed heat source. The cooling fiber is attached to the heating sample e.g., EO-IR detect ...

ABSTRACT: A new method for manufacturing thin, flexible, portable high efficiency III-V PV modules that can be folded and rolled. In particular, IMM3J cells are lifted-off their growth substrate and transferred to a polyimide blanket sheet holding up to a few hundred cells. They are fully encapsulated. The interconnects are made with novel use of electrically conductive adhesives and polymers. Th ...

ABSTRACT: Ozone generation for decontamination systems has been around for many decades but systems, such as dielectric barrier discharge (DBD), are not suited to field use and the high voltages employed present serious safety problems. RF-driven microplasma devices are a unique technology for low-cost and low-power-voltage plasmas in vacuum and in air up to atmospheric pressure with a number of ...

ABSTRACT: We propose to apply modern massively multicore processors to a key problem area of interest to the Air Force: multiphysics computational fluid dynamics (CFD) and computational structural dynamics (CSD) solvers. The capabilities of the CPU to solve these problems have been increasing steadily, but the CPU is still a general-purpose device designed to run diverse applications such as word ...

ABSTRACT: The purpose of the proposed Air Force Phase I STTR program is to fabricate semiconductor nanomembrane based photovoltaic (PV) power sources on flexible substrates, using Virginia Tech NanoCMOS Laboratory"s SOI silicon nanomembrane technique in combination with NanoSonic"s pioneering Polynanoguard antireflection copolymer nanocomposite materials, which afford high levels of antireflectio ...

ABSTRACT: With a cutoff at 1.6 & #956;m, high carrier mobility, and the potential to be integrated with silicon integrated circuits, Ge offers the possibility to achieve large size arrays and small pixel pitch for high sensitivity SWIR imaging near room temperatures. In addition, integrating SWIR image sensors on flexible substrates opens new applications and opportunities for night vision system ...

ABSTRACT: In the proposed work, Physical Sciences Inc. (PSI) will team with MIT to develop a chip-based spin-squeezed atomic clock with a fractional frequency stability below the standard quantum limit. This will be accomplished by the development and fabrication of an atom chip that includes an integrated optical micro-cavity for confinement, imaging, and readout of the trapped cold atomic ense ...

ABSTRACT: Military and other software systems often face the need to accept untrusted software components into the system. The proposed research will enable secure integration of untrusted software components by (1) isolating these components using application-level (per-process) virtualization; (2) assisting the customer in constructing a security policy tailored to each untrusted component; (3) ...

ABSTRACT: Networked PCs are critical to the success of data-based missions, and the complex software they execute is both the source of their power and their prime area of vulnerability. Applications and services are often composed of multiple software components developed by different vendors or open source communities, who may in turn incorporate components developed by another tier of vendors. ...

ABSTRACT: This STTR Phase I project addresses exploit attempts being mounted against applications code and modules with vulnerabilities that need to be protected. The team's strategy is to"blacken"or isolate applications and the inter, and intra communications paths between them and the lnternet using innovative algorithms developed by Embry-Riddle Aeronautical University (ERAU). We plan to ...
