Vadum will implement and test a novel Nonlinear Automated Measurement System (NAMS) instrument package designed in Phase-I to perform very high dynamic range RF two-tone measurements.The NAMS will be an integrated instrument with software for performing rapid, automated linear and nonlinear large signal RF measurements.The prototype instrument utilizes an active feed-forward canceller to achieve a ...

Vadum will develop the canine Hearing Protection and Active Communication (HPAC) system. The HPAC system will provide clear and reliable audio communication between the handler and the canine, and provide at least 30 dB of noise reduction for loud external sounds. The HPAC system will facilitate high-quality canine situational awareness of ambient environmental sounds, at a settable, limited sound ...

Paratroopers and air-dropped supplies play a critical role in rapid deployment of Army manpower, firepower, and supplies almost anywhere in the world.Typically, a squad or platoon and their supplies are involved in an operation, with the intention that once on the ground, they can regroup (locate each other, locate the supplies) and then execute their mission. This regrouping of the team can be di ...

This proposal addresses the need to further develop a robust and validated soundscape modeling tool for accurate predictions of biological, geophysical, and anthropogenic activity in CONUS and OCONUS environments. The Phase II development of the geospatial and acoustic training databases will focus on strengthening the geospatial diversity of the data by employing purposeful data collection techni ...

Currently nuclear-based gauges are the most widely used equipment in the construction industry to measure moisture and density of pavement materials. Such measurements are very accurate, rapid, and non-destructive. Attempts to replace these nuclear methods by non-nuclear methods have shown strong limitations. For this project, we propose to integrate nuclear and seismic technologies to measure t ...

We plan to implement a planar Molecularly Controlled Semiconductor Resistor (MOCSER) gas sensor on both InAs and InN platforms for the ppt-ppm detection of NOx and H2O. Kyma Technologies and Duke University will leverage Duke"s leading MOCSER based NOx sensor technology which uses surface functionalization of InAs with hemin (chloroprotoporphyrin IX iron(III)) to create a strong affinity for NOx. ...

Aluminum Gallium Nitride (AlGaN) has broad dual use applications for power transistors, high frequency transistors, high power Schottky barrier diodes, and solar-blind detectors, as well as ultra-violet laser diodes and ultra-violet light emitting diodes. This unique material system spans the capabilities that lie between Gallium Nitride (GaN) and Aluminum Nitride (AlN), enabling custom tailored p ...

The objective of proposed work is to demonstrate the feasibility of obtaining AlGaN films of any composition with dislocation densities below 1x106 cm-2 on native nitride substrates either by sustaining a pseudomorphic state or by reducing the number of threading dislocations by specific stress relieving schemes at the interfaces or within the thickness of the layers.

There continues to be a need for low cost production and shipment of fuel-grade ethanol from agricultural sources. Ethanol from agricultural sources has many advantages including developing fuel independence and significantly reducing greenhouse gases. Also, bio-ethanol has significant value as an oxygenated and octane improver. Although ethanol from agricultural sources has many advantages, th ...

In this SBIR effort we will design (Phase I) and demonstrate (Phase II) an integrated silicon electronic-photonic upconversion receiver that when used with our photonic backend will allow for a highly sensitive, real-time, and economical millimeter wave (mmW) imaging system. The development of this chip leverages recent progress in CMOS and SiGe HBT high speed analog circuit design and integrates ...
