THE GENERAL PURPOSE ICE DETECTOR/ACCUMULATOR PROPOSED IN THIS DOCUMENT EMPLOYS TWO ULTRASONIC SENSING MODES. RAYLEIGH WAVES (SURFACE WAVES) ARE USED TO DETECT THE ONSET OF ICING, AND TIME-OFFLIGHT MEASUREMENTS IN A NORMAL INCIDENT REFLECTION OF ULTRASONIC PULSES FROM THE ICE LAYERS ARE USED FOR MEASURING APPRECIALBE BUILDUP THICKNESS OF THE ICE (>0.5MM). THE BASIC PRINCIPLES UNDERLYING A TIME-OF-F ...

ARMY EXPLOSIVES NEED TO BE MADE LESS SENSITIVE AND LESS VULNERABLE TO SYMPATHETIC DETONATION AND FIRE. COST, PROCESSABILITY AND STABILITY ARE ALSO IMPORTANT. KSE HAS UNDER DEVELOPMENT A PROCESS FOR THE DIRECT NITRATION OF HYDROXYL TERMINATED POLYBUTADIENE (HTPB), A RUBBERY BINDER CURRENTLY IN USE FOR EXPLOSIVES AND PROPELLANT CHARGES.THE FUNCTIONAL GROUPS ADDED TO THE HTPB SHOULD INCREASE THE ENER ...

A PROGRAM IS PROPOSED TO EVALUATE THE FEASIBILITY OF DEVELOPING A FORTY-POUND COMPACT LIDAR SYSTEM BASED ON A UNIQUE LSI LASER DESIGN. THE GOAL IS A SYSTEM HAVING FOUR FREQUENCY AGILE COAXIALLY ALIGNED CO2 LASER BEAMS WITH AN ENERGY OUTPUT OF AT LEAST 100 MJ, A PRF OF 100 HZ, AND TUNABILITY TO 66 LINES AT A TUNING RATE OF 100 HZ. THE SYSTEM SHOULD USE NINE INCH COLLECTING OPTICS, STATE-OF-THE-ART ...

THE OBJECTIVES OF THE STUDY ARE (1) TO ASSESS THE PRESENT STATE OF KNOWLEDGE OF EM PROPAGATION IN IONIZED MEDIA AS IT PERTAINS TO THE NEEDS OF THE ARMY FOR REAL-TIME, RELIABLE, CONTINUOUS AND SURVIVABLE COMMUNICATIONS AND (2) TO IDENTIFY AND RECOMMEND THE TECHNICAL AREAS OF IONOSPHERIC PROPAGATION THAT REQUIRE FURTHER INVESTIGATION IN ORDER TO FULFILL THE ARMY'S PRESENT AND FUTURE COMMUNICATION RE ...

IMPROVE CONTROL AND FASTER SWITCHING SPEEDS HAVE BECOME NECESSARY TO ACHIEVE ACCEPTABLE SYSTEM PERFORMANCE OF MILLIMETER WAVE PHASED ARRAY SYSTEMS. THE PROPOSED STUDY HAS THE OBJECTIVE OF APPLYING QUASIOPTICAL TECHNIQUES TO SOLVE THE TECHNOLOGICAL PROBLEMS ASSOCIATED WITH DISCRETE CONTROL DEVICES. THE INTRODUCTION OF PIN DIODES INTO APPROPRIATELY DESIGNED METALLIC GRATINGS CAN BE EMPLOYED TO VARY ...

A TOXIC GAS DETECTOR IS DESCRIBED THAT DEPENDS UPON OPTICAL TECHNIQUES FOR ALL GASES MONITORED. SPECTROSCOPIC PROPERTIES OF THE GASES IN THE INFRARED REGION ARE USED TO SPECIFY EACH OF FIVE GASES TO BE DETECTED, AND THESE GASES ARE MEASURED IN A SINGLE MULTIREFLECTIVE MEASUREMENT PHOTOMETER. GASES ARE DISTINGUISHED BY SPECTRAL CORRELATION TECHNIQUES, INVOLVING THE INTERACTIVE USE OF A SELF-CONTAIN ...

A NATURAL, MICROCOMPUTER-BASED, MAN/ROBOT INTERACTION LANGUAGE IS PROPOSED FOR USE BY NON-TECHNICAL PERSONNEL. BASED ON A THREADED INTERPRETIVE LANGUAGE (FORTH), SUCH A LANGUAGE WILL NOT REQUIRE THE EXTENSIVE OVERHEAD OF AN OPERATING SYSTEM USUALLY ASSOCIATED WITH HIGH-LEVEL, NATURAL LANGUAGES, AND HENCE CAN BE IMPLEMENTED ON INEXPENSIVE, SINGLE-BOARD COMPUTERS. MOREOVER, BECAUSE OF THE INTERPRETI ...

OUR OBJECTIVE IS TO DETERMINE THE FEASIBILITY OF APPLYING OUR FIBER OPTIC MICROSENSOR TO RECEPTOR-BASED ASSAY IN THE FIELD. OUR MICROSENSOR SENSES ONLY WITHIN THE SUB WAVELENGTH THIN EVANESCENT ZONE ON THE WALL OF AN OPTICAL FIBER. IT IS BEING APPLIED TO FLUOROIMMUNOASSAY FOR BOTH MILITARY AND COMMERCIAL APPLICATIONS. THE ASSOCIATED INSTRUMENT HAS THE POTENTIAL OF BEING MINIATURIZED (POCKET SIZE), ...
