A PROMISING METHOD OF SIGNIFICANTLY INCREASING THE OPERATING SPEEDS OF ROBOTS WILL BE INVESTIGATED. THE PRIMARY ROBOT SPEED LIMITATION IS FROM RESONANCES IN THE ARM, AND THE ASSOCIATED DIFFICULTY OF CONTROL LAW DESIGN. THE PROPOSED APPROACH FOCUSES ON ANNIHILATING THE VIBRATIONS AS THE ARM APPROACHES THE ENDPOINT OF ITS MANEUVER WHICH IS USUALLY THE ONLY POINT WHERE STRINGENT ACCURACY IS REQUIRED. ...

PULSED POWER CONDITIONING FOR ELECTROMAGNETIC LAUNCHER SYSTEMS REQUIRES FAST-ACTING RHEOSTATS (MODULATORS) WITH ENOUGH THERMAL INERTIA TO ABSORB TENS OF MEGAJOULES ADIABATICALLY WITHIN MILLISECONDS, AND ENOUGH COOLING CAPABILITY TO DISSIPATE THE ABSORBED ENERGY BETWEEN LAUNCHES. ONE UNEXPLORED CLASS OF DEVICES FOR ACCOMPLISHING THIS ARE MODERN VERSIONS OF THE CLASSIC CARBON PILE RHEOSTAT, IN WHICH ...

DEVELOPMENT IS PROPOSED OF A SMALL, SELF-CONTAINED POWER UNIT CAPABLE OF OPERATING UNATTENDED FOR LONG PERIODS WITH GREAT RELIABILITY. THE UNIT IS INTENDED FOR INCORPORATED AS THE STORAGE BATTERY TRICKLE CHARGER IN A DATA GATHERING AND COMMUNICATIONS SYSTEM FOR THE ARCTIC AND OTHER REMOTE ISOLATED AREAS. THE ENERGY SOURCES ANTICIPATED FOR THE POWERUNIT INCLUDE NUCLEAR (RADIOISOTOPE) AND CHEMICAL ( ...

A NOVEL CONCEPT IS PROPOSED FOR THE DEVELOPMENT OF A PERSONNEL DOSIMETER FOR IONIZING RADIATION, SUCH AS, GAMMA RAY. THE DOSIMETER USES A SPECIALTY CLASS OF RADIATION SENSITIVE CONDUCTIVE POLYMERIC COMPOSITIONS. WHEN EXPOSED TO LOW DOSAGE OF IONIZING RADIATION, THE POLYMERIC COMPOSITIONS WOULD UNDERGO A SUBSTANTIAL CHANGE IN ELECTRICAL CONDUCTIVITY. AS A SLIGHT CHANGE IN CONDUCTIVITY CAN BE DETERM ...
