SUPERCONDUCTIVE CIRCUITS ARE PROVING EFFECTIVE IN PROCESSING VERY HIGH-SPEED DATA STREAMS. FOR EXAMPLE, AN 8-BIT ANALOG-TO-DIGITAL CONVERTER (ADC) WITH 4.4 EFFECTIVE BITS AT 4 GHZ, AND 2 EFFECTIVE BITS AT 7 GHZ HAS BEEN DEMONSTRATED. AN ADC PERFORMANCE OF 6 EFFECTIVE BITS AT 10 GHZ SHOULD BE ACHIEVED. HOWEVER, THE ABILITY OF SUPERCONDUCTIVE CIRCUITS TO WORK AT SUCH HIGH DATA RATES RENDERS IT DI ...

INVESTIGATORS HAVE DEMONSTRATED A 6-BIT A/D CAPABLE OF ABOUT 5 BITS OF RESOLUTION AT 4 GHZ INPUT BANDWIDTH AND ABOUT 4 BITS OF RESOLUTION AT 7 GHZ INPUT BANDWIDTH. THE INPUT BANDWIDTH IS ABOUT 10 GHZ (THE 3DB POINT). HOWEVER, THE RESOLUTION AT GHZ FREQUENCIES IS LIMITED BY DYNAMIC DISTORTIONS IN THE THRESHOLDS PROPORTIONAL TO THE INPUT SIGNAL SLEW RATE. A NEW COMPARATOR DESIGN HAS BEEN SIMULATE ...

RESEARCHERS ARE CREATING INNOVATIVE FINDINGS TO PASSIVE DAMPING AND ACTIVE VIBRATION CONTROL TECHNOLOGIES WHICH PLAY A MAJOR ROLE IN THE SUCCESS OF DESIGNS OF DYNAMIC STRUCTURES. UNIQUE OPPORTUNITIES EXIST WITH THE USE OF MODULES OR PATCHES INCORPORATING PIEZOELECTRIC MATERIAL AND MICROELECTRONIC INTELLIGENCE, ENABLING HIGHLY EFFECTIVE DAMPING AND VIRBRATION CONTROL. SUCH DISCOVERIES ALLOW FOR ADV ...

EFFICIENT ACQUISITION OF 3-D SURFACE COORDINATES WOULD HAVE OBVIOUS UTILITY IN MACHINE VISION APPLICATIONS SUCH AS METROLOGY FOR QUALITY CONTROL, OBSTACLE DETECTION FOR MOTION CONTROL, AND TARGET LOCATION FOR DOCKING. YET THERE IS NO UBIQUITOUS METHOD FOR 3-D DIGITIZING. EXTANT TECHNOLOGIES SUFFER FROM A VARIETY OF SHORT-COMMINGS INCLUDING NEAR-FIELD BLINDNESS, CUMBERSOME CALIBRATION SCHEMES, LIMI ...
