AUTOMATED BLOOD CELL ANALYSIS IS A ROUTINE FUNCTION IN THE CLINICAL HEMATOLOGY LABORATORY. HOWEVER, THE FLOW CYTOMETRIC INSTRUMENTATION PERFORMING THESE TESTS MAY HAVE FUNDAMENTAL LIMITATIONS REGARDING MEASUREMENT OF RED BLOOD CELL VOLUME, RED BLOOD CELL HEMOGLOBIN CONCENTRATION, AND ACCURATE CLASSIFICATION OF WHITE BLOOD CELL SUBPOPULATIONS. THE "HIGH-END" INSTRUMENTS HAVE BECOME VERY COMPLEX AND ...

BETWEEN COCHLEAR IMPLANTS AND QUADRI/PARAPLEGICS, THERE ARE APPROXIMATELY 700,000 PERSONS IN THE U. S. WHO WOULD BENEFIT FROM PROSTHETICS UTILIZING NEURAL OR NEUROMUSCULAR STIMULATION. SUCH SYSTEMS REQUIRE IMPLANTABLE, HIGH-SPEED, BI-DIRECTIONAL, TRANSCUTANEOUS DATA TRANSMISSION IMMUNE TO VARIATIONS IN THE LOCAL ENVIRONMENT. TO DATE, DATA LINKS INDEVELOPMENT ARE NOT PROJECTED TO MEET THE COMBINED ...

Endoscopic exploration of the utero-fallopian region is useful and may become a more general observational modality if a viewing instrument can be build with a front end that is disposable and inexpensive, has a small diameter with potential for transcervical introduction without anesthesia, and can provide high image resolution. The goal is the development of a falloposcope with high resolution i ...

THE NEXT GENERATION OF HIGH POWER, HIGH FREQUENCY ELECTRONIC DEVICE TECHNOLOGY WILL BE BASED ON WIDE BANDGAP SEMICONDUCTOR MATERIALS SUCH AS SIC, GAN AND DIAMOND. OF THESE, SILICON CARBIDE IS THE MOST PROMISING MATERIAL FOR NEAR TERM APPLICATIONS, SINCE ITS PROCESSING SHARES MANY COMMON FEATURES WITH WELL-ESTABLISHED SILICON PROCESSING. TECHNOLOGY HAS BEEN DEMONSTRATED FOR PRODUCING OHMIC AND SCHO ...

HIGH POWER AND HIGH TEMPERATURE ELECTRONIC DEVICES ARE IMPORTANT IN BOTH DEFENSE AND COMMERCIAL SYSTEMS. BETA SILICON CARBIDE IS AN EXCELLENT CANDIDATE SEMICONDUCTOR MATERIAL FOR DEMANDING APPLICATIONS DUE TO ITS HIGH BREAKDOWN VOLTAGE, RELATIVELY LARGE BAND GAP, HIGH THERMAL CONDUCTIVITY AND HIGH MELTING POINT. USE OF SILICON CARBIDE THIN FILMS IS HAMPERED, HOWEVER, BY THE INABILITY TO REPRODUCIB ...

IN-SITU MONITORING OF CRITICAL MATERIAL PROPERTIES WOULD GREATLY ENHANCE PROCESS CONTROL OF A WIDE VARIETY OF MANUFACTURING TECHNOLOGIES. POSITION SENSITIVE FIBER OPTIC X-RAY SCINTILLATION DETECTORS (PSSD) CAN BE USED TO SIMULTANEOUSLY MEASURE SEVERAL CRITICAL SOLID POLYCRYSTALLINE MATERIAL PARAMETERS SUCH AS THICKNESS, CRYSTAL STRUCTURE, CRYSTAL PERFECTION, PREFERRED ORIENTATION, AND RESIDUAL STR ...
