New Jersey Microsystems proposes to develop an economical thermopile array with sensitivity maximum in the long wave infrared region (LWIR). Current infrared detectors are too expensive to be widely deployed in large numbers. The proposed MEMS technology is simpler, more manufacturable, and therefore less expensive than bolometer and ferroelectric devices with competitive D* sensitivity. The th ...

Accurate and timely surveillance of objects in the near-Earth space environment is becoming increasingly critical to US national security. One of the main difficulties in this domain is efficiently and accurately modeling trajectories of the vast number of objects in orbit around the Earth. The orbital trajectory of a single object is typically modeled as a second-order system of equations which ...

Space surveillance is the component of space situational awareness focused on the detection of resident space objects (RSOs) and the use of multisource data to track and identify space objects. While the propagation of the states of RSOs has been investigated extensively over the last fifty years, the correct propagation of their covariance or the more general (non-Gaussian) probability distribut ...

A mathematical framework for detection and classification of weak, distributed patterns on computer networks is proposed. The framework will provide rigorous methods for understanding performance bounds and optimality of intrusion detection methods, while also providing concrete and implementable algorithms. The algorithms will find immediate application in cyber-security efforts, as well as mor ...

Prime Research and the University of North Carolina at Charlotte propose to devevelop space-variant nano-optical elements to integrate passive spectral and polarization filters directly into infrared focal plane arrays. This novel technology will enable multi-mode detection by allowing pixels to be uniquely tuned for wavelength and polarization across a focal plane array using a simple fabricatio ...

The Progeny – University of Utah team proposes a new approach for flow noise reduction to improve acoustic sensor performance. Our proposal is to investigate the ability of controlling the turbulent flow by utilizing acceleration which makes the flow locally laminar. Our proposed method of achieving acceleration is to send the flow around a concave surface, by adding a “two-dimensional bump ...

Stealth is a primary consideration in design and operation of ships and submarines in the Navy fleet. Noise in hydraulic systems and piping is one source of unwanted noise. A method to measure and monitor this noise is essential to controlling and eliminating these noise sources. With the assistance of UMASS Dartmouth we will present a method to externally measure the fluidborne sound pressure lev ...

Electromagnetic launchers or rail guns are a key component of the Navy’s all-electric ship of the future, but they lack the durability required for repeated firings. TDA Research and the University of Nevada, Reno (UNR) are developing a tough, durable and conductive refractory metal coating that will protect the copper alloy conductors (rails) from the extreme heat and wear conditions inside the ...

The Missile Defense Agency (MDA) seeks technical investigations related to the development and application of advanced electronic materials, processes, and devices to meet its need for radiation hardened, high performance electronics for critical space and missile applications. With the advent of smaller transistor dimensions and reductions in price per bit, significant changes in materials and pr ...

While there are established methods available in determining the fatigue life of critical rotating components, there is still room for improvement for better understanding and prediction of life limiting factors. Improved risk assessment of jet engine disk components would require probabilistic modeling capability of the evolution of microstructural features, residual stresses and material anomali ...
