ABSTRACT:Current military systems laser rangefinding and designation systems require multiple detectors, which make such systems large, heavy, and power hungry, which limits application to larger, high-value platforms. The proposed Phase II program addresses the need for a single, compact high-resolution SWIR imager with see-spot/time-spot capabilities. In the Phase II program, Voxtel will develop ...

YTP will develop technology that provides a high performance, modular Li-ion battery with: redundant safety features, safer thin, metal case cell designs; fin/micro-channel thermal control system; and an evaporating fluid system that rapidly quenches failing cells to prevent thermal runaway and fratricide. The end goal of the proposal is making a lighter, longer lasting, less expensive, safer JSF ...

ABSTRACT: A fast, 1-cm diameter cylindrical gradient index (GRIN) nonlinear optical (NLO) refractive index lens, with large radial linear and nonlinear optical index gradients in all three optical axes will be fabricated using ink jet printing (IJP). The goal is to demonstrate the ability to modulate the third-order susceptibility by 1000x over silica. To achieve the desired performance, existin ...

ABSTRACT: Using roll-to-roll (R2R) -compatible inkjet-print (IJP) deposition and nanoimprint (NI) photolithographic patterning methods, a series of passive and electro-optic (EO) -modulated waveguide structures will be fabricated and characterized. The measured data will be compared to modeled results and the information will be used to improve device designs. Modeling will also be used to demons ...

ABSTRACT: High-yielding inkjet print (IJP) deposition technologies will be developed for hybridizing the ultra-small pitch semiconductor detector arrays and readout integrated circuits (ROIC). The goal is to develop a method, alternative to the thermocompression hybridization methods currently used, that can be used to hybridize high pixel density focal plane arrays (FPAs), with 5 micron, and sma ...

ABSTRACT: Lightfield 3D displays are being developed to reduce viewer eyestrain normally found on stereoscopic displays caused by the mismatch of the focus and stereo vergence on the display. These lightfield or Field of Light Displays (FoLD) systems generate a light field by any of several approaches including holographic, volumetric, integral-imaging, and multiple-2D-depth-planes. The differen ...

ABSTRACT: Interest in tracking human movement has been motivated by the wide array of its applications in health care, military training, sports, and entertainment. Currently, there is no single motion capture technology that is perfect for every possible use. The most common method of tracking movement is based on optical motion analysis systems. However, these systems are costly, not portable, ...

ABSTRACT: VSI proposes the development of the SIGMA (Speedy Imagery Geo-registration and Motion Analysis) system, which will address three key requirements by the end of Phase II: (i) adapt to different type of sensors, sensor-configurations and sensor operating conditions, (ii) handle large amount of data in real-time or close to real-time using limited resources, and (iii) operate under conditi ...

DESCRIPTION (provided by applicant): Underage alcohol consumption is a public health concern with numerous negative sequelae, including adoption of other risky behaviors (smoking, other drug use, at-risk sexual behavior, drinking and driving), increased rates of depression or suicidal ideation, poor academic achievement, and behavioral problems (delinquency, violence, crime). Adolescents who drink ...

PROJECT SUMMARY This project aims to fill the urgent need for a safe and engaging intervention that promotes physical activity in a population of patients with chronic diseases (e.g., diabetes, asthma, osteoarthritis, and chronic heart failure). Compelling evidence suggests that physical activity is an effective therapeutic intervention for numerous chronic diseases. However, in spite of the wide ...
