Power system upgrades for next generation ground combat vehicles require technology advances such as higher operating temperature, greater power density, and increased functionality. While many bidirectional DC-DC converters are available on the market, inefficiency and legacy semiconductor technologies require active thermal management and large package sizes. Silicon Carbide based power electron ...

Turbochargers are critical components of internal combustion (IC) engines on Unmanned Aerial Vehicles (UAVs). Control of the turbocharger speed is needed to avoid operation near resonant speeds and to optimize turbocharger performance and life. Currently, there are no robust flight sensors capable of measuring titanium blade turbocharger speeds at high temperatures with limited access. In this pro ...

CR&D will develop a hand-held, temporary tattoo printer designed to be used to print tattoos on the skin of warfighters at the POI or healthcare facility with the intent of replacing TC3 cards and aftercare instructions respectively. The intent is to eliminate the loss of information resulting from various touch-points along the continuum of care or in the days following outpatient release. The pr ...

Large-area, sub-wavelength texturing can convert walls, windows, ceilings, floors, and even vehicles into advanced surfaces that enhance, shield, or manipulate electromagnetic waves. These textures, or “nanopatterns,” enable transformational technologies for warfighter protection and advanced offensive capabilities. Applications include multispectral camouflage, holograms, heads-up displays, a ...

The U.S. Army has a requirement for a shaped charge warhead that can maintain its penetration capability while spinning. The current solution, a linear fluted liner, is optimal over a narrow band of spin rates compared to the span of rates experienced by a typical spin-stabilized munition over its effective range. To increase performance on target, a solution that is effective over a larger range ...

This Phase II effort prototypes a minimal volume microscope designed to allow for a 2-D digital holographic imaging concurrent with field of view spectral content at video frame rates. The use of a laser driven IR dual beam frequency comb, coincident with the optical beam path required for a digital holographic image, will allow rapid acquisition of both the spatial and the spectral content associ ...

The Army requires methods of resolving soil state characteristics that can be integrated into geospatial analysis efforts related to land surface modeling, terrain reasoning, vehicular mobility, and dismounted mobility. To address this need, Creare is developing the SoilMAP software framework. SoilMAP is intended to enable Army geospatial analysts to ingest, fuse, process, and visualize soil moist ...

Over a decade ago, security practitioners highlighted threats posed by memory corruption exploits subverting systems through manipulation of security-critical non-control-data — without ever corrupting application control-flow. Since that demonstration, however, the full power of data-oriented attacks went largely unnoticed until very recently. One reason for this recent emergence is that exploi ...

Vadum will develop a Scalable Integrated Magnetic Sensing System (SIMSS) that detects and classifies solid explosive substances with up to 10 inches of standoff in buried or concealed non-metallic housings. The low-SWaP 100W design represents the first truly portable NQR-based sensor in the market. The RF sensor identifies solid nitrogen-based explosives (ammonium nitrate, potassium nitrate, sodiu ...

The overall goal of this project is to develop an in-process defect monitoring and correction technique for additive manufacturing (AM) of aluminum alloy to improve repeatability for geometric dimensions, material properties, and quality. In Phase I, Sentient collaborated with Johns Hopkins University Applied Physics Lab, and successfully completed all proposed tasks demonstrating two key capabili ...
