ABSTRACT:Systima Technologies, Inc. proposes the development of an unmanned hypersonic test vehicle recovery system that will greatly enhance the effectiveness of hypersonic flight testing.Systima plans to perform a comprehensive review of the various hypersonic vehicle test environments and recovery requirements in order to develop recommendations for suitable vehicle recovery technologies for th ...

In this proposal, closed-loop control techniques are developed to eliminate torque harmonics produced by an SRM. To provide vibratory feedback, a piezoelectric-based sensor is incorporated into an SRM drive system to sense the torque harmonics in real time. The advantages of using a piezoelectric-based sensor include its flexibility in terms of placement, its extremely low cost, its durability and ...

We propose to add ultra-wide-band (UWB) wireless connectivity to a wearable, battery powered, finger-worn ultrasound probe and system (under development through a separate contract) capable of performing the FAST exam for use in the battlefield. UWB is particular suited to medical defense needs on the battlefield as the wireless transmission is undetectable, uses low power and has high bandwidth f ...

ABSTRACT: Leviathan Security Group (LSG) has previously created a system called Major Myer, under the DARPA CINDER program, which is capable of detecting exploitation attempts in images of application memory using emulation. It has focused on crashdumps, but is theoretically not limited to this purpose. LSG has since commercialized the technology developed under that project into a product called ...

Modern tactical environments exhibit a wide array of distributed cognition challenges, particularly with the proliferation of device types available to commanders and soldiers. The transition between desktop and handheld device profiles presents a difficult choice for application design, between costly custom development per-platform or scaling technologies that dont adequately address contextual ...

ABSTRACT:This Small Business Innovation Research Phase I project will develop a vacuum compatible, high gradient insulator (HGI) based on low SEE yield aluminum nitride (AlN) ceramic with high surface flashover resistance for pulse power applications. In Phase I we will design and fabricate AlN-Metal HGIs, and investigate the effects of AlN and metal layer thicknesses, and number of layers on the ...

ABSTRACT:Computer network defense tools are plagued with an excessive amount of information, frequently in the form of false positives. Rather than attempt to train automated tools to detect attack events more reliably, we propose to build upon existing 'honey-net' technologies to interfere with the reconnaissance phases of an adversary's attack. We will build upon our existing CyberChaff (TM) tec ...

A compact, low-power near/shortwave infrared sensor capable of temporally and spatially resolving battlefield lasers asynchronously under day and night conditions will be developed. The approach is based on an existing active-passive focal plane array (FPA), which readily lends itself to this application. In Phase I, after working with U.S. Army stakeholders to refine the requirements and the cont ...

ABSTRACT:To address the need for a low-cost, high-pixel-density focal plane array (FPA) hybridization process, a nanotechnology-based metal interconnect and bonding approach will be refined. The process is compatible with wafer-to-wafer, chip-to-wafer, and chip-to-chip processing, requires only modest capital investment, and can be performed with high yields at less cost and finer pitch compared t ...

ABSTRACT: To produce high dielectric strength insulator materials, our approach, called Optimized Additive Manufacturing for High Dielectric Strength (OAHDS), will optimize fused filament fabrication (FFF) 3D printing in order to fabricate high density parts. Currently, thermoplastics 3D printed via FFF have dielectric strengths one to three orders of magnitude lower than injection molded parts ma ...
