NEAR-SURFACE DEFECTS IN SEMICONDUCTORS HAVE A PRIMARY INFLUENCE UPON DEVICE PROPERTIES, PARTICULARLY THE YIELD. IT WOULD BE VERY USEFUL TO BE ABLE TO MAP SPATIALLY THE DENSITY AND TYPE OF DEFECTS NEAR A SEMICONDUCTOR SURFACE EITHER AS A WAFER QUALITY CONTROL STEP OR TO SUPPORT DEVICE PHYSICAL EXPERIMENTS. CONVENTIONAL TECHNIQUES USED FOR THIS PURPOSE SUFFER FROM ONE OR MORE OF THE FOLLOWING LIMITA ...

THERE IS A NEED FOR A GOOD STRUCTURAL CERAMIC MATERIAL THAT CAN BE USED AT HIGH TEMPERATURES IN THE OXIDIZING AND CORROSIVE ATMOSPHERE OF TURBINE ENGINES AND THAT CAN BE FORMED ECONOMICALLY TO COMPLEX SHAPE WITH LOW WEIGHT. THE OBJECTIVE OF THIS RESEARCH PROJECT IS TO INVESTIGATE A NEW FAMILY OF CERAMIC COMPSITE MATERIALS THAT MAY MEET THOSE REQUIREMENTS. IT IS BASED ON CHEMICALLY VAPOR DEPOSITED ...

PROJECTILE PULSE GENERATOR (PPG) HAS BEEN CONCEIVED TO SATISFY ANTICIPLATED AIR FORCE REQUIREMENTS. THE PPG IS EXPLOSIVELY DRIVEN AND IS INTENDED TO MEET THE REQUIRMENTS STIPULATED IN THE SBIR

IN THIS PROGRAM, THE EFFORT WILL CONCENTRACTE ON ATTAINING A COMPLETE UNDERSTANDING OF THE PHYSICS INVOLVED IN INFERRING THE SHAPE OF THE FORWARD SURFACE OF A CARBON/CARBON NOSETIP FORM THE ECHO WAVESHAPE GENERATED BY A NULTRASONIC TRANSMITTER/RECEIVER MOUNTED ON THE BACK FACE. THE HIGHEST PRIORITY WILL BE FOCUSSED ON THE ABILITY TO IMPROVE THE INTERPRETATION OF PREVIOUS AND FUTURE FLIGHT DATA USI ...

INVESTIGATE THE FEASIBILITY OF DESIGNING CIRCUITS TO ENABLE BETTER SECURE TRANSMISSION OF DATA. DEVELOP SPECIFIC APPROACHES FOR ACHIEVING SUCH DESIGN AND DETERMINE CORRESPONDING CHARACTERISTICS IN TERMS OF ADDITIONAL CIRCUITRY, RELIABILITY OF OPERATION, POSSIBILITY OF DETECTION, POSSIBILITY OF DISABLING OR COUNTERACTING, ACCIDENTAL SWITCHING, AND EASE OF INCORPORATION INTO EXISTING DESIGNS.

TAPE RECORDERS PRESENTLY USED AS SPACEBORNE MASS STORAGE DEVICES HAVE A HISTORY OF BEING UNRELIABLE AND REQUIRE EXTENSIVE AND COSTLY GROUND TESTING TO PROVIDE THE CONFIDENCE NECESSARY TO PASS LAUNCH READINESS. EVEN THEN THEY DO NOT ALWAYS ADEQUATELY PERFORM THEIR FUNCTION ON ORBIT. THE OBJECTIE OF THIS PHASE I PROGRAM IS TO DEVELOP A BUBBLE MEMORY MODULE WHICH CAN BE USED AS A BUILDING BLOCKFOR TH ...
