ABSTRACT: The floor of an ALC is like a well-orchestrated dance. However, when an unexpected failure occurs, it can introduce significant delays in not only the specific aircraft"s maintenance, but of the entire network of systems. 21st Century Systems, Inc. (21CSi) is in the position to answer this challenge with a concept called Reactive Aircraft Maintenance System via Evolutionary Scheduling ( ...

We propose to bandgap-engineer the antimony-based Group III-V compound semiconductor material system to realize a dualband focal plane array (FPA) made up of stacked multi-barrier Type-II strained layer superlattice (SLS) photodiodes. Two longwave infrared (LWIR) spectral bands will be imaged in alternate frames by using a readout multiplexer that flips the voltage bias across the FPA from frame ...

Use of motorcycles helmets significantly reduces the risk of fatality or serious brain injury to riders in the event of a crash, but riders often do not wear helmets in warm weather because of thermal discomfort. We propose to develop an innovative ventilation and cooling system that will maintain a cool, dry environment inside the helmet while also meeting applicable safety standards. The key inn ...

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 ...

Degraded visual environment (DVE) presents a challenge for helicopter pilotage, particularly in close proximity to potential hazards such as vegetation, poles, wires, buildings, vehicles, personnel, equipment, nearby terrain, other aircraft, or ship superstructures. To safely negotiate these hazards, the aircrew must maintain a continuous awareness of the environment that can include both static a ...

ABSTRACT:Cognitive skills/capabilities are important for the military personnel to fulfill tasks and to ensure mission efficiency and success. In the past decade, there are abundant researches suggesting that non-invasive brain stimulation via transcranial direct current stimulation (tDCS) holds great promise to enhance a soldier's cognitive performances. Although models to predict the tDCS curren ...

ABSTRACT:Transcranial direct current stimulation (tDCS) can potentially provide a safe, non-invasive, and painless method for enhancing cognition, vigilance, and learning rate. However, further research is required to evaluate, demonstrate, and understand its efficacy in a controlled and reproducible manner. Hypothesis-driven studies of tDCS require targeted delivery of electrical currents to spec ...

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 ...

ABSTRACT:The LWIR spectrum is well suited for moderate- to long-range free space communications because of its atmospheric window and low scattering by dust, haze, precipitation, and fog. The recent impressive laser development of QCLs is poised to provide the high speed LWIR transmitter for such a free space communication system; a corresponding advance in LWIR detectors is needed to enable the h ...

ABSTRACT:Inspection of inserted compressor blades is difficult due to the complicated geometry of the blades, the need for high accuracy, and the safety risk posed by undetected cracks. At present, the time and cost associated with airfoil inspection forces many parts to be condemned and replaced after limited service. Creare proposes to develop an Automated Airfoil Inspection System (AAIS) that p ...
