DESCRIPTION (provided by applicant): Disorders of the pancreas affect more than one million persons in this country with nearly 3 billion in health care costs. The incidence rate of chronic pancreatitis (CP) is rapidly increasing and may be related to expanded alcohol abuse. Advanced CP causes severe structural damage to the pancreas leading to chronic abdominal pain, endocrine failure (diabetes ...

A key technology enabler for next generation ISR systems is low loss, lightweight, flexible wire and cable, particularly the RF power routing from the fuselage to the rotodome in the E-2 Hawkeye airborne early warning aircraft, which requires specially designed copper based coax Aircraft Transmission Lines (ATL). Copper is the established choice of conductive material for these ATLs, but copper’ ...

We propose to experimentally investigate MOCVD (Metal Organic Chemical Vapor Deposition) as a technique for growing high-quality Type-II InAs/(In)GaSb SLS (Strained Layer Superlattice) photodiode epi material. In collaboration with the University of Maryland, our goal is to grow, process, and measure longwave infrared detector material and devices and compare them to identical MBE (Molecular Beam ...

In Phase I, we will demonstrate a dualband InAs/GaSb strained layer superlattice (SLS) photodiode with bias-selectable 3-5 and 8-12 micron spectral response. Bandgap engineering will be used to minimize dark current and make array processing simple and robust with the goal of demonstrating a prototype dualband focal plane array (FPA) in the Phase I Option itself. In Phase II, we will optimize FPA ...

The proposed project addresses the need for an efficient cost-effective building cooling system which is powered by solar heat collected using low to medium temperature solar collectors. Such a system avoids the need for expensive high-temperature solar collectors and has potential to result in a truly cost-effective system that could achieve significant market penetration. Benefits to the public ...

The ability for engineers to assess the impact of their preliminary design of solid rocket motor (SRM) performance and combustion stability is the focus of this proposal. The SRMs of the future will be designed for increased performance. Since ballistic excursions, instabilities, and sporadic forces on rocket motors have catastrophic results, Software and Engineering Associates, Inc. (SEA) has mad ...

A new, improved fidelity solid rocket ballistics model will be built on a commercial CFD platform. The CFD platform includes a coupled solid mechanics solver, allowing for tight coupling between the grain burnback and the motor gas dynamics. An aero-acoustic component of the platform will be used to determine mode shapes and acoustic decay characteristics from the ballistics results.

Solid State Scientific Corporation (SSSC) is pleased to propose a Phase I SBIR program to develop a unique spectral imaging sensor prototype based on micro-optics with a COTS astronomical camera. The micro-optic separates the image into spectral views of the image that are spatially and temporally registered. The proposed approach has been demonstrated on a telescope to simultaneously image space ...

In this NAVY SBIR Phase I program, we propose a radio frequency (RF) direction finding sensor for low probability of intercept (LPI) RF radar system. This sensor consists of a dielectric fisheye lenses and an innovative focus plane detector array (FPDA). The fisheye lenses, as a RF antenna, have been broadly used in camera and electronic-optical systems (from visible to infrared wavelength). In th ...

This Small Business Innovation Research (SBIR) Phase I project aims to develop novel field detectors and memory devices capable of detecting magnetic field of an electromagnetic pulse (EMP). The sensor is made of magnetic nanowire arrays consisting of magnetic nanowires embedded in an insulating matrix, and is able to memorize the incoming rf magnetic field pulse as short as 100ps and survive in a ...
