Identification and Significance of the Problem In the last 20 years, the use of personal, wireless communications devices by society has exploded. Nearly every adult (and many children) in developed and developing countries carries at least one communications device usually in the form of a mobile phone. In addition to mobile phones, a host of other wireless technologies such as Bluetooth, FRS/GM ...

During Phase I, the Blackhawk hanger bearing and oil cooler fan bearing applications were studied in detail, including analysis of vibration and temperature data from used oil cooler bench tests (conducted by Sikorsky) and used hanger bearing bench tests (conducted by Sentient). This data, along with an analysis of operational and environmental conditions, has allowed us to identify the probable r ...

A recent increase in the occurrence of pilot parachute deployment hesitation events during training has focused attention on the flow field about parachutists in freefall. An improved understanding of this flow will contribute to better equipment and improved safety. Computational Fluid Dynamics (CFD) analysis is a powerful technique for exploring such flows. Once validated against experimental d ...

The goal of this project is to design, build, and test an active electromagnetic induction (EMI) sensor array for detecting and characterizing IEDs. At low frequencies (below a few kHz), an EMI sensor is a magnetometer that primarily responds to susceptibility targets (i.e., ferrous objects). The main difference is that, while a magnetometer uses the earth’s field as the illuminating source, an ...

The Army seeks to standardize all equipment on its battlefield logistics fuel, JP-8. JP-8 is difficult to use for small-scale, low-power applications, however, since its low vapor pressure and complex composition inhibit complete vaporization. Existing methods for vaporizing logistics fuels are not sufficiently controllable to support highly efficient catalytic combustion processes, or impose un ...

A personal air ventilation system (PAVS) can dramatically improve the environment inside chemical/biological protective clothing, protecting the health and safety of soldiers and enabling peak physical/mental performance for long periods. However, existing air blowers that can produce the flow rate and pressure drop needed for a PAVS are too heavy, inefficient, and noisy for a man-portable system ...

Thermal batteries are the power source of choice for many weapon systems. While thermal batteries offer designers several key advantages, the design and integration of this technology into new applications suffers from two significant impediments. The first is the lack of suitable design tools, and the second is the time-consuming and expensive effort necessary to qualify a new battery design thro ...

A MEMS based multicolor beam steering system for generating 2D spot arrays has been demonstrated. For effective quantum computation applications, the optical system requires further optimization and refinement. In phase II, parameters such as beam scanning frame rates, insertion loss, system scalability and methods to improve the stability and ruggedness of the optical system will be enhanced towa ...

We propose to develop multiresolution representations and algorithms for synthetic terrain environments. They will be used for representing large terrain models as well dynamic and atmospheric simulations. Our ultimate goal is to increase the validity of the simulation by incorporating the multiple models at varying resolutions. We will use the OneSAF simulation Product Line Architecture Framework ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...
