Our nation’s warfighters require advanced armor to give them the best protection while allowing mobility to perform their missions. This proposal will develop two powerful tools to aid future body armor advancements. First, this research program will develop a statistical analysis software that will predict likelihood of impacts based on defined attack scenarios (i.e. rifle, distance and firing ...

Electromagenetic (EM) launchers could radically decrease the cost to launch and orbit micro-satellites and could provide launch with little lead time, but thus far it has not been feasible to achieve this capability with linear EM launchers. The objective of this research is to determine the viability of circular launch accelerators. Phase I explored designs consisting of a maglev sled accelerate ...

This program will further the development of large area freestanding GaN substrates (150mm or greater) and develop a bulk GaN substrate characterization protocol to help reduce the variability in GaN homoepitaxial growth results which have prevented low cost, high voltage, vertical GaN power devices from being realized in an economically viable way.

The region of the millimeter and submillimeter-wave frequency bands, from 100 GHz to 3 THz (wavelengths of 3 to 0.1 mm, respectively), are some of the least explored and yet information rich regions of the electromagnetic spectrum. This region of the spectrum, referred to as the terahertz (THz) frequency regime, roughly 300-3000 GHz, is ripe for development. A major impediment to development of a ...

ATA Engineering has developed a wavelet-based damage squeezing methodology for generating optimally compressed fatigue test signals that produce an equivalent amount of fatigue damage in a predictably reduced amount of time compared to the baseline (uncompressed) signals. Fatigue-critical signal characteristics (e.g., magnitude, phase, frequency, and sequencing relationships) are identified in the ...

Laser guide stars (LGS) are artificial sources of light produced by laser-induced fluorescence from sodium atoms in the mesosphere between 85 km and 100 km altitude. The fluorescence can be detected on the ground with a telescope and used as a reference for compensating atmospheric aberrations in astronomical and space observations in conjunction with an adaptive optics system. Sodium LGS are vita ...

We propose to investigate, in collaboration with MGH Voice Center and Altec, Inc., application of surface electromyography (sEMG) to assessing cognitive workload, strain, and overload. Specifically, sEMG sensors placed on the face and neck will detect emotional/motor responses to workload strain. The proposed effort will build on the substantial sEMG experience of our partner, MGH (including resea ...

Stottler Henke proposes PACT to address the threat posed by unknown/novel bacteria. Stottler Henke’s solution leverages AI/ML technologies to assess the pathogenic potential of unknown/novel bacteria for DARPA’s Biological Technologies Office. Threat assessment is inferred from phenotype as characterized by a series of assays developed by Harvard University as part of DARPA’s Friend or Foe p ...

In this Phase II STTR Project, Team UtopiaCompression (UC) will adapt its 3D ultrasound prototype device to address key research questions posed by AF TPOC and end-users (in particular, Eglin AFB Medical Community- Invisible Wounds Center, family/concussion clinics and emergency rooms). The prototype uses an innovative ultrasound design technology to capture 3D data of anatomical structures (here, ...

The proposed project will develop subject-specific FE models of the head and integrate them with a full body finite element model. The combination of patient-specific head geometries with the generalized body model will provide a platform with which to apply improved boundary conditions for the head and neck, including applied muscle tension and the application of appropriate kinematics of the hea ...
