The key innovation of this proposal is the use of Time Modulated Ultra-Wideband (TM-UWB) technology to develop a low cost radio system that allows both voice communication and tracking positions of fire fighters inside buildings. This radio has several characteristics which make it ideal for tracking multiple individuals without line-of-sight. During Phase I we have performed many tests, incl ...

This is a Phase 2 proposal to develop an instrument to simultaneously measure particle size, velocity, and concentration in applications characterized by a large size range and high particle concentration. The instrument will be based on the Pulse Displacement Technique whose feasibility was demonstrated during Phase 1. Experiments performed during Phase 1 demonstrated a high accuracy in meas ...

This Phase II SBIR Project will provide optimization framework and technology for Interoperable Message Passing Interface Technology, and the underlying Message Passing Interface Standard. This effort represents a challenge and Opportunity. With the emergence of cluster computing, there are many opportunities to connect diverse parallel programming Environments based on the MPI programming mo ...

High performance NIR APDs suitable for photon counting are presently unavailable. New high sensitivity, high speed photodetectors operating from 1.0 to 1.6 microns are needed for both military and commercial applications. New research has demonstrated APD structures, which use a Si multiplication region and an InGaAs absorption region. This device shows high sensitivity, very high speed, low ...

As flip-chip bonding becomes the predominant standard in the electronics industry, the increased proximity between dice surfaces and packaging materials will require a significant reduction in the latter's alpha particle activity in order to avoid soft errors. Emission rates at or below 0.001 a/cm2/hr are desirable, which is well below the 0.0050 a/cm2/hr capability of today's best detectors. ...

As ever more of industry and commerce moves onto electronic networks, there is a growing appreciation for the usefulness of expressive general models of enterprise activities, such as design and manufacturing. Ontologies are commitments to formal declarative multi-purpose representations with clear semantics that can serve as a solid foundation for such models. While there has been much work ...

Development of efficient spray combustors requires a complete understanding of fundamental phenomena that influence and control the overall spray combustion process. Toward this end, detailed experimental characterization of spray flames is essential. This includes measurement of various fuel droplet parameters such as droplet size, velocity, number density, temperature, composition, and droplet ...

The specific problem addressed by the proposed research is the development of a scanner for storage phosphor plates with significantly better positional and intensity accuracy than the current state of the art. The new scanner will be based on the use of a "scanning head" scanning approach which is more simple, accurate, and stable than the approaches previously used. This results in stable and ...
