THE DEVELOPMENT OF A LOW COST, 3-AXIS, NUMERICALLY-CONTROLLED, OPTICAL GENERATOR SUITABLE FOR USE IN GRINDING GLASS OR CERAMIC PARTS, AS WELL AS FOR MACHING METALS TO OPTICAL TOLERANCES IS DESCRIBED. THIS INNOVATIVE DESIGN USES ROTARY BEARINGS ON ALL THREE AXES BECAUSE OF THEHIGH ACCURACY AND LOW COST PROVIDED. THE NC MACHINE WILL HAVE THE CAPACITY TO GENERATE EITHER ROTATIONALLY SYMMETRIC OR ASYM ...

The overall abjective of this proposed project is the development of detailed definitions for the interfaces defined by the ABBET architecture. Signal models wil developed based upon the C/ATLAS set of signal nouns. A Test Foundation Framework (TFF) will be implemented to demonstrate the ability of test program or test program component transfer across multiple test platforms. This phase also w ...

IN THE MANUFACTURING OPERATION OF MACHINING, IMPROVED COMPONENTS FOR MACHINE TOOLS IN ULTRA-HIGH SPEED MACHINING HAVE THE POTENTIAL TO DRAMATICALLY INCREASE PRODUCTIVITY ANDREDUCE COST. THE ABILITY TO INCREASE SPEED AS WELL AS METAL REMOVAL RATE RESULTS IN SIGNIFICANT INCREASE IN PRODUCTIVITY AS WELL AS A COST REDUCTION IN MANUFACTURING. A COMPOSITE CUTTING TOOL INSERT OF SIC WHISKERS REINFORCED A ...

THIS PROJECT WILL DEVELOP THE APPLICATION OF STATE-OF-THE-ART CHARGE-COUPLED DEVICE (CCD) IMAGE DETECTORSTO THE PROBLEM OF THE AUTOMATIC ANALYSIS OF DNA-SEQUENCING GELS. SUCCESS OF THIS PROJECT WILL RESULT IN COMMERCIALIZATION OF AN INSTRUMENT CAPABLE OF READING, INTERPRETING, AND STORING DNA SEQUENCE INFORMATION DIRECTLY FROM AN AUTORADIOGRAM OF A DNA-SEQUENCING GEL. SUCH AN INSTRUMENT WILL STREN ...

THE PRIMARY OBJECTIVE OF THIS PROPOSAL IS THE DESIGN, CONSTRUCTION AND EVALUATION OF A NOVEL SCANNING TUNNELING MICROSCOPE (STM) FOR ROUTINE SURFACE MICROTOPOGRAPHICAL ANALYSIS. THIS PROTOTYPE INSTRUMENT IS DESIGNED TO COVER AN EXTENSIVE MAGNIFICATION RANGE FROM 2500X TO 10(8)X. SINCE THE ENTIRE STM UNIT IS SMALL ENOUGH TO BE MOUNTED ON A6-IN CONFLAT FLANGE, IT CAN BE READILY INSTALLED ONTO ANY UL ...

A PORTABLE PHOTOMETER IS PROPOSED CONSISTING OF A DEVICE WHICH IS PLACED OVER THE TRAFFIC SIGNAL LENS. AN INTERNAL OPTICAL SYSTEM ALLOWS MEASUREMENT OF THE SIGNAL CANDLEPOWER AT VARIOUS ANGLES OF INTEREST. THE INSTRUMENT ELECTRONICS AND LIGHT EMITTING DIODES PROVIDE A PASS/FAIL INDICATION FOREACH MEASUREMENT ANGLE, WITH THE GO/NO-GO SET POINT BEING AUTOMATICALLY ADJUSTED TO DIFFERENT CANDLEPOWER V ...
