xß-Ga2O3 has emerged as a potentially disruptive semiconductor with a predicted breakdown field of ~8 MV/cm which is more than twice the breakdown field for the incumbent wide bandgap semiconductors GaN and SiC. The availability of ß-Ga2O3 bulk substrates sets this material apart from other wide bandgap materials for power electronic applications. However, the challenge is to find suitable epita ...

Integral bladed rotors (IBR) manufacturing is an essential part of gas turbine fabrication for modern fighter aircraft. Stringent dimensional tolerance and surface finish requirements necessitate precision manufacturing and consequently, resulting in increased cost. Our Phase II proposal will demonstrate innovative high speed machining (HSM) technologies the Air Force needs for affordable fabrica ...

Military systems operate in complex, adversarial environments where their initial planned operations are often overcome by events, but soldiers use those systems in creative ways to achieve their mission objectives. For example, complex ground robotic systems that were initially deployed for surveillance and explosive ordinance disposal have instead been used as decoys, ammunition carriers, and ot ...

Trusted Semiconductor Solutions will demonstrate how high-reliability substrate material, leading-edge commercial memories, advanced manufacturing processing, and our radiation circumvention and recovery approach enables high density electronic payloads needed for next generation guided missile and space applications. We will develop a prototype system-in-package (SiP) that utilizes commercial mem ...

SIFT, along with Drs. Julie Adams and Ramesh Sagili of Oregon State University (OSU), propose to develop “Resilient Emergent Properties for Autonomous Agent InteRactions” (REPAIR). Building upon recent innovative work in swarm control and optimization, and applying new observations of specific defensive and adaptive characteristics of honeybee colonies, REPAIR will provide biologically inspire ...

Soldiers employ multiple digital assets on the battlefield for communications and surveillance. These sources do not support SECRET level classification and may not ever. The Nett Warrior system is an integrated system that allows soldiers to use Android devices for SECRET level tactical and front-line use (e.g., common operating picture, data feeds, real-time communications, etc.). These new non- ...

Wearable devices have grown to meet the demand for continuous, noninvasive vital signs monitoring in the military and civilian health care markets.These devices have largely excluded pulse oximetry because non-traditional sites, such as the chest, arm and legs, pose a challenge. We have previously demonstrated the ability to accurately monitor pulse oximetry on the chest, arms and calf.This projec ...

An anti-submarine warfare concept is proposed in which a low-cost and easily-deployable temporary submarine detection zone is created in littoral waters. The concept uses solid-state magnetic field sensors to detect the passage of submarines, and acoustic transmitters to relay the data to a small number of in-water receiver units. The data is then communicated from these units to a manned off-sit ...

75333S Nanoindentation is the primary technique for assessing the nanomechanical behavior of small volumes of materials. With this technique, the force required to produce a given displacement into a sample by a sharp diamond tip is measured, and the hardness of the material being tested is determined analyzing the force-displacement curve. However, the microstructural origins of the measured me ...

The overall goal of our Phase II project is to demonstrate innovative, scalable high-performance machining (HPM) processes the Navy needs for thin-web, large-pocket Ti-6Al-4V firewalls and bulkheads. The anticipated benefits of the program are the ability to fabricate unitized structures resulting in reduced labor costs, part count and improved quality while achieving desired weight requirements a ...
