Intelligent processing of battelfield sensor data and other information provides substantial force-multiplying benefits. The timely and cost-effective leveraging of information provides a signficant advantage over adversaries not possessing comparable information processing capabilties. Among these is automatic target recognition (ATR). Under previous and current Federal funding, AbTech has develo ...

Accurate Automation Corporation (AAC) has developed a new artificial neural network processor (NNP) based upon a sparse Multiple Instruction Multiple Data (MIMD) structure which is ideally suited for Electronic Warfare (EW) applications. The proposed research will investigate the use of the AAC NNP for EW applications such as emitter identification which is used in ELINT, ESM, and RWR receivers. T ...

We propose to develop an automated Pilot Induced Oscillation (PIO) detection and compensation system. This will use artificial neural networks to increase speed and the envelope of operation. PIO is caused when a pilot overcompensates during a "high gain" task such as landing, takeoff, refueling, dropping stores, or tracking. It can also be caused by inefficiencies in the inner loop controllers ...

The feasibility of fabricating hypersonic aircraft components from metastable Beta Titanium alloy (Beta 21S) will be investigated. Techniques for the fabrication of the leading edges, inlet, and nozzle areas of a hypersonic (Mach 4-5) testbed aircraft from Beta 21S will be selected and preliminary drawings, specifications, and test procedures for these components will be developed.

Aculight proposes the development of a frequency tunable source suitable for LADAR measurements from compact military platforms. The source will use a fixed frequency diode pumped solid state drive laser and an optical parametric oscillator, tunable from 1.6 to 2.4 microns. Output energies will be over 100 micro-J through the spectral range at pulse rates of 10kHz. The major technical challenge, ...

High pulse energy, high repetition rate, tunable, narrowband sources are needed for optical pumping of mid-infrared gas laser converters. The source needs continuous tunability over the 1-3 micron band to access different overtone bands in various gaseous gain media. Due to the need for diode pumping of the source, efficiency is critical to minimizing diode costs. Our approach is efficient gene ...

One of the major problems facing data management today is that collection capabilities far outstrip analysis capabilities. This is particularly true of scientific and engineering data sets. Analysis methods require access that cross file/data granule boundaries. We propose to address this problem by integrating unified data models of scientific data as embodied by the widely used data formats CD ...

The continued use of arsine gas and/or its derivatives is vital to the manufacture of a wide variety of semiconductor devices. While the use of arsine is growing, it poses serious environmental and safety problems in the industry. New methods must be found that permit the facile trapping and detoxification of arsine and its derivatives. Advanced Technology Materials, Inc. (ATM) has gained a reputa ...

The potential applications of microelectromechanical systems (MEMS) have only begun to be recognized. This technology demands thin film materials with exceptional microstructural quality for high performance and processes with high yields. For piezoelectric microactuator applications, thin film lead zirconate titanate (PZT) is the leading material choice. Furthermore, substitutional modificatio ...

Multilayer thin films deposited onto Si wafers often exhibit high residual stresses during processing, leading to structural failure and/or electrical breakdown. Traditional scanning x-ray diffraction provides an accurate measurement of complex stress behavior in multilayer structures, but is difficult to carry out on a routine basis. Laser deflection methods are easy to perform but provide a li ...
