This briefing summarizes the findings and conclusions resulting from the CNA Marine Corps Microminiature/Automatic
Test Equipment Military Occupational Specialty Code (2M/ATE MOS) study. The purpose of the study was to analyze a number
of alternative Circuit Card Assemblies (CCA) repair strategies for MC ground systems. The alternatives considered ranged from
evacuating all CCA functions to repairing them all. We also considered varying the repairer workforce composition and repair
location. We found that the current repair practices, assuming that the MC assigns the number of repairer man-years we estimate
are needed, saves about $75 million a year over what it would cost to evaluate and replenish failed CCAs. More money could be
saved if all CCAs were repaired at a central location (Electronic Maintenance Companies). The report also finds that 2M workload
does not appear to warrant a primary MOS.

The goal of this project was to develop mathematical models of new methods for controlling solitons in optical storage loops
and optical switching devices. Such control techniques are important for applications involving the generation and processing of
high-speed optical bit streams, and devices based upon them can be thought of loosely as basic optical

In instrumentation facility for the evaluation for electro-optic and sensor protection materials has been implemented at the
University of Washington. This facility is being used in the evaluation of materials of interest to defense and telecommunications
industries and government laboratories including Air Force Research Laboratories. Preliminary results have shown that dendrimer
materials are the materials of choice for electro-optic and sensor protection applications.

This patent application discloses a circuit for selectably generating a plurality of preselected digital output signals which are
precise and accurate, and among which the circuit can switch rapidly. In one embodiment, the outputs are connected to analog
circuit signals, and drive a optical laser such that choice of the particular outputs of the circuit permits controllable switching of
the laser output wavelength.
