GENERAL PURPOSE PROCESSOR ARITHMETIC LOGIC UNITS (ALUS) TYPICALLY IMPLEMENT LARGE MICRO-CODED INSTRUCTION SETS TO PROVIDE SYSTEM FLEXIBILITY, WITH THE ULTIMATE GOAL OF SUPPORTING A WIDE BASE OF APPLICATIONS. THE LARGE NUMBER OF INSTRUCTIONS RESULTS IN A COMPLEX, RELATIVELY SLOW CHIP ARCHITECTURE. IN EFFECT, BY BASING THEIR SYSTEMS ON GENERAL PURPOSE ALUS, COMPUTER MANUFACTURERS TRADE-OFF SPEED OF ...

MANY DISABLED INDIVIDUALS ARE CURRENTLY BENEFITTING FROM THEFIELD OF THERAPY CALLED THERAPEUTIC RECREATION. EVERY MAJORREHABILITATION CENTER HAS A SEPARATE AND GROWING RECREATION THERAPY DEPARTMENT AS THIS FIELD OF THERAPY GAINS RECOGNI- HAVE SPECIAL EQUIPMENT IN ORDER TO PARTICIPATE. THE DIFFICULTY IN FINDING SUCH EQUIPMENT IS PERSONALLY UNDERSTOOD BY THE PRINCIPAL INVESTIGATOR, WHO WAS PARALYZED ...

THE USE OF THERMAL NEUTRONS AS A TOOL FOR BAGGAGE INSPECTIONIS AN ESTABLISHED TECHNIQUE, WITH A PROTOTYPE SYSTEM CURRENTLY BEING TESTED FOR AIRPORT FEASIBILITY AS AN EXPLOSIVE DETECTION DEVICE. THIS SYSTEM COULD POSSIBLY BE MODIFIED FOR INDIVIDUAL BAGGAGE IDENTIFICATION THROUGH THE USE OF IMAGING OR ACTIVATION DETECTION OF SUITABLE TAGS. HOWEVER, FEASIBILITY TESTING OF THIS CONCEPT AND THE COMMERC ...

AS A RESULT OF THE INCREASING VOLUME OF AIR TRAFFIC IT HAS BECOME APPARENT THAT A NEED EXIST FOR A DEVICE OPERATED ON BOARD THE AIRCRAFT TO WARN THE PILOT OF OTHER AIRCRAFT THAT MAY POSE A POTENTIAL COLLISION. OUR OBJECTIVE IS TO DEVELOP A INEXPENSIVE TCAS I SYSTEM (AD-VANCED TECHNOLOGY AIRBORNE TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM) THAT MEET "ALL" OF THE FAA TCAS I REQUIREMENTS AS PER RTC ...

THE OBJECTIVES OF PHASE I ARE TO DETERMINE HOW WELL THE SMALL SCALE TESTS CURRENTLY USED FOR SCREENING EXPLOSIVES, AND THE MODELS THAT DESCRIBE EXPLOSIVE BEHAVIOR IN THE SMALL SCALE TEST AND IN THE FULL SCALE MUNITION, CAN PREDICT THRESHOLDS OF EXPLOSIVE REACTION IN THE OPERATIONAL FULL SCALE MUNITION. FULL SCALE MUNITIONS WILL BE STUDIED TO DETERMINE THE CRITICAL MODE(S) OF EXPLOSIVE REACTION THA ...

THE PROBLEM IS TO DEVELOP SHALLOW DEPTH ROTATING BANDS FOR HIGH VELOCITY PROJECTILES THAT WILL MINIMIZE BARREL EROSION AND REDUCE DRAG TO AN ABSOLUTE MINIMUM, USING INEXPENSIVE METHODS OF RETAINING INJECTION-MOLDABLE THERMOPLASTIC MATERIALS. THE PROPOSED APPROACH IS TO TRADE OFF STRONGLY-RETAINED LOW DRAG ROTATING BANDS AGAINST BARREL EXIT-SEPARATING BANDS THAT ARE ASSISTED IN RETENTION INSIDE THE ...

THIS PROPOSAL IS BROKEN INTO FOUR PROJECTS. THE FIRST PROJ-ECT IS THE IMPLEMENTATION OF A QUICK RETRIEVAL SYSTEM FOR LASER DISCS THAT WILL ALLOW USERS TO RAPIDLY ACCESS LARGE AMOUNTS OF DATA VIA INTERNAL COMPUTER CONTROLLED HASHING TA-BLES EITHER STORED ON THE LASER DISC OR MAINTAINED VIA MAIN-TENANCE SOFTWARE ON OTHER SOTRAGE MEDIA. THE SECON PROJECT CONSISTS OF A LIBRARY OF SUBROUTINES TO ACCESS ...
