The standard technique for the recording of telemetry data in range operations has been instrumentation tape recording. This has provided the capability for recording data at high data rates for extended periods of time. While convenient for recording, this technique suffers drawbacks in processing and playback of the data. Due to the serial nature of the medium, no capability exists for near-re ...

Astralux is developing heterobipolar transistors (HBT) using a SiC base. This device operates above 500 C with a current gain in excess of 100. Most of the effort went into design, technology, and characterization of these devices. To make the HBT into a commercial product, the technology of contacts and packaging must be developed. This proposal considers a joint project with NAWCAD and a pac ...

Astralux, having recently made the first transistor structure to operate above 500 C with a current gain exceeding 100, proposes to explore the limitations of the transistor's power handling capability. At room temperature, this transistor carries a current density one order of magnitude higher than commercial silicon power transistors. Also it is proposed to study the maximum frequency at which ...

The Integrated Surface Treatment System (ISTS) Plasma Spray CNC Workcell was originally designed to repair/refurbish a broad range of common worn parts so that they could be returned to service with a minimum of specialized operator skill or ancillary tooling. The concept holds great promise for both the US Government and for commercial industry. However, even though the thermal spray process is r ...

Our proposed research for Phase I is in response to US Navy solicitation for low-cost synthesis methods for producing nanocrystalline ceramics to offer the best properties for modem technological applications. We propose to process high purity unagglomerated and engineered nanocrystalline AIN as a model material, by a low-cost method called Gas Phase Combustion Synthesis (GCS) to combat two key is ...

1The recent experience has shown that parallel systems are no longer experimental and useful systems can be built (e.g. the Connection Machine) to solve real problems (e.g. linear algebra, partial differential equations). It is also no longer the question of whether a Tera FLOPS system can be built, rather it is how can such powerful systems be used effectively. In many cases only a small fraction ...

We propose the definition and development of a low cost, highly compact coastal zone hyperspectral imager, the Sea-DASI, for quantitative, few meter resolution remote sensing of the ocean coastal zone via robotic( high altitude) or light aircraft. The instrument is based on a Digital Array Scanned Interferometer(DASI) invented and patented by the PI. Sea-DASI will Observe in the-visible-near infra ...
