The Multiple Degree of Freedom Measurement (MDFM) System, developed under Wright Laboratory, has been identified as having strong commercial potential as a significant enhancement to existing products in the machine tool industry for machine tool calibration or coordinate measuring machine enhancement. The MDFM is in need of revision to incorporate state-of-the-art technology, to prepare the devi ...

The adaptive single user receiver invented at AF LAB has been shown to suppress multiuser and certain forms of narrow-band interference in adecision directed mode during the entire transmission, without requiring knowledge of other users spreading codes, timing or phase information in direct-sequence proposal, we investigate the use of our single user receiver for secure communications as required ...

The final prototype of the Microcircuit Board Repair apparatus will be capable of laying down or lifting metal strips with micrometer dimensions. Under real time computer control, the translation stages will be fully automated or manually controlled. The end user will monitor the process in real time using a camera attached with the source. Laying down the metal lines will be done using Laser C ...

Conventional methods for detecting traces of chemical warfare agents require: (a) collection of air, soil, or water samples, (b) analytical laboratory operations, such as chemical separation, to isolate suspected agents, and (c) laboratory analysis. Typically, this process may take days or weeks. Such long time lags and the inherent cost of labor intensive laboratory analysis are serious obstacles ...

SUBSTANTIAL PROGRESS HAS BEEN MADE IN RECENT YEARS TO DEVELOP AND VALIDATE MODELS WHICH CAN PREDICT THE PHYSICAL EFFECTS OF NUCLEAR WEAPONS ON STRATEGIC STRUCTURES. SIGNIFICANT UNCERTAINTIES REMAIN, HOWEVER, IN THE CONFIDENCE LEVELS ATTRIBUTABLE TO THESE PREDICTIVE CAPABILITIES. THIS APPROACH WOULD IDENTIFY AND PRIORITIZE THOSE ACTIVITIES, ALONG WITH THEIR ASSOCIATED BUDGETARY AND SCHEDULING CONSI ...

THE DISTRIBUTION OF THE MAGNETIC FIELD IN A HIGH CURRENT PLASMA DEVICE PROVIDES IMPORTANT INFORMATION ABOUT THE DEVICES OPERATION. TRADITIONAL FARADAY ROTATION, ZEEMAN EMISSION SPECTROSCOPY, AND MAGNETIC PROBE TECHNIQUES SUFFER FROM POOR SPATIAL RESOLUTION BECAUSE THE MAGNETIC FIELD EFFECT IS INTEGRATED ALONG THE LINE OF SIGHT FOR THE OPTICAL TECHNIQUE AND THE PROBES PERTURB THE PLASMAS. A LASER I ...

IT IS PROPOSED TO DEVELOP A STRESS GAGE FOR THE RANGE 1/2 TO 10 KILOBARS, SUITABLE FOR USE IN SOIL AND WEAK ROCK, IN FREE-FIELD AND ON-STRUCTURE APPLICATIONS. IN ADDITION TO THE USUAL COMPRESSIVE STRESS SENSING CAPABILITY, THERE WOULD ALSO BE A SHEAR STRESS SENSING OPTION; THE TWO MEASUREMENT CHANNELS COULD ALSO BE COMBINED IN A SINGLE GAGE BODY PACKAGE. FIELD DATA RECORDING COST AND SYSTEM PROBLE ...

Survival of present day microelectronic circuits depends on their protection from self generated and external electromagnetic interference. This proposal is oriented toward the class of interference generally referred to as overvoltage transients. Means for mitigating these transients include gas discharge tubes, and various solid state devices. Each of these has their own advantages in particu ...
