Diode-laser arrays operating in the visible region of the spectrum offer advantages for illuminator applications, particularly for night and water penetration capability. Recent developments in diode-laser materials allow operation throughout the visiblespectrum. At this time, red diode-laser technology is more mature than the existing blue-green or violet diode-laser technology. The novel aspe ...

DESCRIPTION (provided by applicant): Over 60,000 prosthetic grafts, which are comprised of either polyethylene terephthalate (polyester) or expanded polytetrafluoroethylene (ePTFE), are implanted in the United States each year. Medium (6-8mm) and small (l t5mm) internal diameter (I.D.) prosthetic arterial grafts continue to have unacceptably high failure rates when used in the clinical setting. T ...

DESCRIPTION (Unedited Applicant's Abstract):When people with diabetes reach end-stage renal disease they must undergo either dialysis or transplantation. About 200,000 Americans need artificial kidney machines to stay alive. These machines rely on sterile dialysis membranes to remove toxic materials from the bloodstream. More than 30 different polymers or polymer blen ...

DESCRIPTION (Verbatim from the Applicant's Abstract): This Phase I SBIR application seeks support to develop and evaluate a naturally-occurring extracellular matrix (ECM) bioscaffold material for tissue engineering applications; specifically, the repair and/or restoration of congenital defects in which lost or missing tissue is the limiting factor for s ...

Rugged, comfortable and reliable physiological monitoring systems are required to allow military commanders and medical personnel to assess the basic health and readiness of the warfighter. Direct monitoring of the health and status of individual warfighters is defined as a key capability for the next generation of warfighter ensemble. Monitoring every warfighter is stated as a system performance ...

An abrasive blasting nozzle is a complex aero-acoustic noise source, characterized by super-sonic, two-phase flow. Noise from an abrasive blasting nozzle is comprised of three sources: (i) turbulent mixing noise (ii) shock-associated noise and (iii) jet impingement noise. It is not uncommon for abrasive nozzles to generate noise levels greater than 120 dB(A); far exceeding typical occupational noi ...

In this proposal, AlphaSense, Inc. (AI) and the Oklahoma State University (OKState) detail the development of a novel Cavity Enhanced Terahertz Absorption Spectrometer (CETAS). Key innovations of the proposed system include: a) the use of a small Whispering- Gallery- Mode (WGM) cavity to achieve very long pathlength; and b) the integration of the WGM cavity with the conventional pulsed and continu ...

The DOD and robotics industry, have a critical need for a motion planning capability that is practical for real-world application of autonomous systems that perform physical motions. Current motion planning systems are too slow; they assume that the environment will be static during motion planning and execution, each of which can take on the order of seconds. Further, these systems typically gen ...

The recent performance increases in graphics processing units (GPUs) have made graphics cards an attractive platform for implementing computationally intense applications. With their numerous parallel computational pipelines and SIMD architecture, modern GPUs can outperform high-end microprocessors by one to three orders of magnitude, depending on the problem. Most work to date at EM Photonics a ...

DESCRIPTION: (provided by applicant) The goal of this program is to develop accelerator mass spectrometry (AMS) as an analytical tool for cancer research, specifically for tracing the interactions of carcinogens and cancer chemotherapeutic drugs with their biomolecular targets. AMS is a highly selective means for d ...
