DESCRIPTION: The fundamental goal of this program is to develop a microfluidics-based artificial kidney that minimizes exposure of blood to artificial surfaces and provides continuous perfusion in a compact, wearable device. This device will provide treatment at low flow rates over long times, greatly reducing concentration and volume transient in body fluids. The key element is a primary separato ...

DESCRIPTION (provided by applicant): Over 60,000 prosthetic grafts, which are primarily comprised of polyethylene terephthalate (polyester) or expanded polytetrafluoroethylene (ePTFE), are implanted in the United States each year. Unfortunately, these grafts continue to have high failure rates due to secondary complications associated with acute thromboses and incomplete, unregulated cellular prol ...

DESCRIPTION (provided by applicant): Functional MRI, diffusion MRI and MR spectroscopy and spectroscopic imaging have great potential for the study and diagnosis of disease and injury, and guiding surgical therapy. All of these methods benefit greatly fromthe added sensitivity, resolution and contrast from high field strength magnets (3T and above). However, the advantages of higher magnetic field ...

Modern military and security scenarios increasingly demand rapid evaluation of human affective states, accurately detecting stress, anxiety, uncertainty, and fatigue (SAUF) to assess warfighter effectiveness or to advance security screening and interrogation objectives. In our Phase I effort, we designed and demonstrated a system to Analyze Facial Features to Enable Operator Condition Tracking (AF ...

This SSTR research project will develop a computerized microscope based imaging system that will allow location and quantization of malarial parasites. The system will automatically scan a blood smear, locating the red cells and parasites. A digital image display will allow interaction with an operator to confirm or reject objects. In Phase II the initial effort to identify trophozoites will be ...

In this effort, Physical Sciences Inc. will develop and implement algorithms and hardware to perform the fusion of information obtained from multiple LWIR passive hyperspectral sensors to provide the capability to determine the extent, absolute geo-location, and 3-D concentration distribution of chemical threat clouds from mobile platforms. The effort will be conducted in conjunction with Professo ...

"In this project, Hstar Technologies and its team will develop a near autonomous combat casualty extraction robotic (c2Exbot) system that: 1) supports autonomous dexterous manipulation, safe casualty lifting and near autonomous navigation control, 2) utilizes a supervisory telepresence operation mechanism, 3) provides near autonomous casualty diagnosis, injury assessment and emergency treatment, a ...

ABSTRACT: Busek proposes, with the MIT Space Propulsion Lab, to leverage successful Phase I proof-of-concept results to develop and deliver a 1mN, micro-fabricated electrospray thruster that features variable Isp and bi-polar operation. The thruster achieves variable Isp at no power penalty by innovative use of a deceleration grid, and operating in purely ionic mode so as to overcome many of the ...

ABSTRACT: Composite materials are increasingly adopted into Aerospace application due to their superior specific strength/stiffness, resistance to fatigue and ability to reduce part-count. Furthermore, it has been demonstrated that by introducing carbon nanotubes (CNTs), multi-functional capabilities can be achieved by virtue of their high conductivity and piezoresistive nature. During the prop ...

ABSTRACT: Providing electrical power for long duration hypersonic flight is a technology that is required to bring about this revolutionary mode of transport. Whether for weapons delivery or for space access, the long duration missions anticipated require a novel approach to the generation of electrical power during flight. Scramjets contain no rotating shafts from which typical generators or mec ...
