Site characterization to detect subsurface contamination is of a enormous interest for both public and private applications. Biotronics is proposing to adapt an arc excitation spectrometry technology originally developed for anlaysis of liquid nutrient solutions at NASA to the detection of heavy metals in soils. A preliminary design will be defined that will permit arc excitation of soil adjacent ...

CHROMEX proposes to develop a monitor system for plasma etch reactors that will, in the Phase I program, demonstrate much improved endpoint detection when compared to currently availabe systems. The Phase II research will extend the monitoring capabilities to all important plasma parameters. The system will provide the feedback information to the reactor controller necessary to produce a flexible ...

We propose, in this Phase I program, to study the feasibility of InP-based Velocity Matched Distributed Photodetectors (VMDP) for operation at 1.55 ¿m wavelength. The VMDP offers the possibility of high-power (100 mW), Wide bandwidth (up to 100 GHz) operation by combining the outputs of many photodetector elements along a transmission line. The basic concept has been demonstrated for the GaAs-b ...

DARPA has identified collaborative computing as a technology not yet adequately developed in the marketplace. This need to share and interactively work with documents and other information objects across separate computer systems is really the underlying human business need that originally drove the creation of network technology, desktop video-teleconferencing, and even the failed earlier indust ...

THE PROJECT IS AIMED AT DEVELOPING A NEW TECHNOLOGY FOR PRINTED INTEGRATED FABRICATION OF ELECTROMECHANICAL SYSTEMS (INCLUDING MULTI-LAYER ELECTRIC CIRCUT BOARDS AS WELL AS OPTOELECTROMECHANICAL DEVICES SUCH AS AIRCRAFT/VEHICLE INSTRUMENT PANELS) AS A MONOLITHIC OBJECT USING A FAST LOW-COST AUTOMATABLE PROCESS THAT IS HIGHLY EFFICIENT FOR PROTOTYPING. THE PROCESS IS BASED ON SOLIDIFICATION OF LIQU ...

This SBIR will explore and develop new automated methods for dynamic fault tolerance in defense electronic systems. The research will investigate using the software of digital signal processor operating systems to pro-actively map defective operations to remaining processors. In the past, fault tolerance has relied on passive redundancy to extend operating life. With software, a simple re-start ...
