Award Data

Hematopoiesis, the regulated production of mature blood cells, is a complex scheme of multilineage differentiation which occurs mainly in the bone marrow of adult mammals. Mature cells are continuously produced from progenitor (or precursor) cells. Consequently, assays which detect these progenitor cells are vital in many research and clinical settings. The current assay procedures suffer from a n ...

The goal of this research project is to determine the viability of an interconnect and probing technology which could be used to test and burn-in unpackaged semiconductors at system level speed, and at operating frequency, with voltage and with temperature margins verified. The focus of the research will be to address directly the most costly limitation to widespread MCM use; the problem of readil ...

The objective of this project is to use the newest advance in the technology of Ferroelctric Liquid Crystal (FLC) displays so that they can be used for Visual Landing Aids as well as other applications. Currently FLC's suffer from serious mechanical and temperature limitations due to the fact that mechanical stress alters the structure of the liquid crystal material. We propose to stabilize the ce ...

The objective of this project is to develop a system for the optimized viewing of medical x-ray film. Illuminators currently used to view radiographs have a fixed-area, spatially uniform light output. This allows extraneous light to degrade visual performance and limits the viewable film density range to the dynamic range of the eye at a given adaptation level. The proposed viewing system will pro ...

THE PRIMARY OBJECTIVE OF THIS PROJECT IS TO DETERMINE THE FEASIBILITY OF INCREASING THE QUANTITY AND QUALITY OF SCIENCE EDUCATION IN ELEMENTARY SCHOOLS THROUGH UTILIZING SCIENCE EDUCATION AS THE CONTENT OF CHOICE FOR A RELATIVELY NEW ADDITION TO THE ELEMENTARY SCHOOL CURRICULUM, FOREIGN LANGUAGE. THE INCLUSION OF FOREIGN LANGUAGE IN THE ELEMENTARY SCHOOL, MORE COMMONLY CALLED FLES, IS A RAPIDLY GR ...

ADEQUATE ELECTRICAL POWER FOR SPACECRAFT OPERATIONS IS A CRUCIAL MISSION TASK. THE ISOTOPE HEAT SOURCES USED IN RADIO-ISOTOPE-THERMOELECTRIC-GENERATORS FOR MANY NASA MISSIONS ARE EXPENSIVE. FOR A GIVEN ELECTRICAL POWER, THERMAL-TO-ELECTRIC CONVERSION WITH AMTEC RATHER THAN CONVENTIONAL THERMOELECTRIC CONVERTERS SHOULD PERMIT REDUCTION OF THE GPHS COMPLEMENT BY A FACTOR OF 3. THE ESTIMATED COST SAV ...

MOST LASER SCANNING SYSTEMS ARE MECHANICAL, UTILIZING A MOTOR TO ROTATE A PRISM, MIRROR, OR HOLOGRAPHIC GRATING. SUCH MECHANICAL SYSTEMS ARE OR RELATIVELY LARGE SIZE AND MASS. THERE IS A NEED FOR A SOLID STATE SCANNING DEVICE WHICH WOULD OFFER BENEFITS OF REDUCED SIZE AND MASS, NO MOVING PARTS, IMPROVED RELIABILITY, LOW COSTS, AND LOW POWERREQUIREMENT. WE PROPOSE TO DEVELOP AN INTEGRATED OPTICS (I ...

THE OBJECTIVE OF THE PROPOSED EFFORT IS TO REDUCE THE SIZE, WEIGHT, AND COST OF THE RELAY OPTICS OF THE AIRCRAFT HEAD UP DISPLAY (HUD), BY REPLACING IT WITH TRANSMISSION HOLOGRAPHIC LENSES. HOLOGRAPHIC LENSES ARE VERY LIGHT AND CAN BE MANUFACTURED AT VERY LOW COSTS. APPLICATIONS OF HOLOGRAPHIC LENSES TO HUD WERE LIMITED IN THE PAST, DUE TO WIDE SPECTRAL BAND OF THE HUD - CATHODE RAY TUBE (CRT). HO ...
