Bugeye Technologies’ concept that a low-cost visual display system with 20/20 acuity using Commercial Off the Shelf (COTS) parts is achievable was validated in Phase I. The technology utilizes an optical element and flat panel display to create a visual module. Multiple visual modules could be joined together to create a Virtual Mosaic Display (VMD). The VMD creates a continuous, high-resolution ...

The oscillating water column (OWC) is a candidate technology for the economical recovery of the projected 17.5 x 1012 kW-hr energy that is available from the world¿s oceans. While the relative dynamics between the OWC system and the incident water waves are mathematically understood, computational solutions have not been used to ¿tune¿ the OWC turbine-generator sub-systems to operate where the ...

The development of very small, versatile, rugged, low power, low noise, one or three-axis short-period seismometers is needed to monitor nuclear detonations. Specifications include total sensor size less than 1 cubic inch, low power consumption, low sensor self noise below the USGS Low Earth Noise Model, and dynamic range of at least 120 dB over a frequency band of 0.2 to 40 Hz. However, all com ...

Most biomass materials, such as switchgrass and corn stover, are very bulky (fluffy) when first collected,making them costly to handle, store, and transport. Current densification methods ¿ include baling, pelletizing, etc, ¿ are too costly, too energy-intensive, or both. A better method to solve these problems is needed to enhance the utilization of biomass. This project will test and devel ...

Accelerators used for nuclear-physics research require megawatts of radio-frequency energy. These accelerators currently employ vacuum-tube power amplifiers or conventional solid-state amplifiers that are inefficient and therefore consume a great deal of prime power. This project will review available transistors, analyze high-efficiency power-amplifier techniques, and experimentally evaluate ca ...

The United States is the second largest producer and also the largest importer of natural gas in the world. The increasing price of natural gas along with a decreasing domestic supply presents an opportunity to develop low-cost replacements for natural gas. Thermo-chemical production of Synthetic Natural Gas (SNG) from abundant, low-cost, domestic coal offers a viable solution to several concerns ...

The noise from turbulent, hot, supersonic jets during take-off and landing, as well as high-Mach cruise at altitude, dominates noise emanating from other powerplant components (e.g., fan, combustor). This intense noise has significant safety implications for launch personnel as well an environmental impact in the form of noise pollution around military installations. The proposed work will build ...

Terbium and Europium doped glasses will be investigated for tunable lasing from 450 nm to 490 nm. They will be pumped by Q-switched frequency tripled 355 nm Nd laser pulses. The Tb materials will also be evaluated for 375 nm laser diode pumping.
