ENIG, in collaboration with SRI, proposes to develop a modeling methodology with predictive and inferential capabilities to address the challenges of designing body armor to resist realistic multiple impacts from burst fire events. Our toolkit will provide an end-to-end modeling capability, grounded in the statistics of realistic impacts from small-arms fire, which would address the final material ...

This proposal will investigate body armor systems to the effects of burst fire. In Phase I, the team of researchers will investigate the spatial distribution of impacts of common burst fire capable rifles, demonstrate a statistical analysis technique, and demonstrate a ballistic model approach while applying this research to a surrogate body armor solution. The program will begin with an analysi ...

This project will complete development of a viable, cost-effective industrial production technique for producing ultrastrong, flexible and tough carbon fibers composed of double-walled carbon nanotubes (DWNTs) and of a small amount of a polymer, based on a continuous manufacturing process. This will be done by refining MERs innovative technology for the efficient continuous production of unique fo ...

Approximately 5-6% of military injuries involve some form of major peripheral nerve injury that has little chance of spontaneous healing. Currently these injuries lead to major impairment of voluntary muscle function in the limbs and extremities, making tasks of walking, reaching, grasping, etc. very difficult or impossible for many patients. Focusing therapeutic treatments to segmental nerve in ...

DoD is concerned about circadian rhythm misalignment in military personnel as it is known to affect judgment, psychomotor skills, and may lead to or be triggered by Post-Traumatic Stress Disorder (PTSD). Correction or maintenance of circadian phase in soldiers participating in military night operations or planning for trans-meridian flights is also of interest. In addition, many veterans who suffe ...

Few-cycle mid-infrared lasers are in high demand for a variety of practical applications including remote sensing of chemical and biological species. NP Photonics and the University of Arizona propose to develop a wavelength tunable and power-scalable optical parametric laser system covering 8-10 micron and capable of producing collimated few-cycle pulses with pulse energy > 100 microjoules. A ful ...

Spontaneous emission is a quantum mechanical process that represents the main source of phase noise in state-of-the-art semiconductor lasers, limiting their coherence, and their suitability for high-speed communication and sensing applications. This proposal aims to develop ultra-high coherence semiconductor lasers on the Silicon/III-V platform with a quantum linewidth of

A critical step in the extraction of elements from ore, especially rare earth elements that are found in complex minerals, is separation. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then ca ...

Empirical-based mathematical framework and computer algorithms, for representing human perception and cognition processes and limitations, which influence the recognition of salient information about rapidly changing events.

As the warfighter is increasingly using more highly integrated instruments, e.g. a laser rangefinder (LRF) combined with a laser designator and an imager, the need to decrease the size of these components becomes more important. Compact small munition applications of rangefinders particularly place an emphasis on size of the optical front end. In order to make the transceiver more compact, speci ...
