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 ...

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 ...

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. ...

DIVER SCIENTIST COMMONLY RELY ON A VARIETY OF INSTRUMENTS TO ACCOMPLISH THEIR MISSION. USING MULTIPLE SPECIALIZED INSTRUMENTS HOWEVER NOT ONLY IS COSTLY, BUT ALSO LIMITS A DIVERS MOBILITY. STILL, MANY CAPABILITIES TAKEN FOR GRANTED BY "TOP-SIDE" FIELD RESEARCHERS, SUCH AS PRECISE NAVIGATION AND COMPUTERIZED RECORD TAKING, REMAIN UNSATISFIED OR ARE NOT ADEQUATELY ADDRESSED BY CONVENTIONAL MEANS. TH ...

SILICON P-N JUNCTION PHOTODIODES (AXUV DIODES) WITH STABLE, THEORETICALLY PREDICTABLE QUANTUM EFFICIENCIES IN THE SOFT X-RAY (1 TO 100 NM) WERE DEVELOPED BY US RECENTLY LEADING TO THEIR USE FOR THE ESTABLISHMENT OF AN INDEPENDENT RESPONSIVITY SCALE FOR THE SOFT X-RAY REGION. THE LARGEST ACTIVE AREA DIODE DEVELOPED SO FAR IS 3 CM(2) LIMITING THE SOLID ANGLES DURING SURFACE ANALYSIS STUDIES. FABRICA ...

A NOVEL PHOTOSTIMULABLE PHOSPHOR IMAGING TECHNIQUE IS PROPOSED TO REPLACE BULKY COUNTING SYSTEMS CURRENTLY USED IN NEUTRON DIFFRACTION AND SCATTERING INVESTIGATIONS. THE SIZE AND SHAPE OF THE PROPOSED DETECTOR CAN BE VARIED TO MAKE IT POSSIBLE TO MOVE THE DETECTION SYSTEM CLOSER TO THE SCATTERING SAMPLE, THEREBY INCREASING THE NEUTRONS AVAILABLE FOR DETECTION AND SHRINKING THE SIZE OF THE EXPERIME ...
