Abstract: Light at known angles is impinged onto an object whose contour is to be mured and a camera is used to receive the reflected light which is then recorded. A computer processes the images, mathematically manipulating them so that surface slopes are known. The slopes are than integrated to obtain local elevations which represent the object contour.

Abstract: An evaporation method of producing a new high Tc superconducting material using fullerene molecules as artificial pinning sites for any magnetic flux that may enter the material.

Abstract: A process for forming a copper alloy which is strengthened while maintaining good electrical and thermal conductivity by the addition of TiN or ZrN consists of external nitridation of a mechanically alloyed powder mixture followed by further mechanical alloying to break down the surface coating which forms during nitridation.

Abstract: A semiconductor cold electron emission device comprising a type I heterojunction formed of a P-type semiconductor mixture of AlN and a N-type semiconductor mixture of SiC which junction is forward biased so that electrons are monoenergetically emitted from the P-type semiconductor mixture.

Abstract: A piezoelectric composite which can be used as a transducer is constructed of parallel piezoelectric ceramic rods set in a passive polymer matrix which has a negative Poisson ratio whereby the electromechanical coupling of the transducer is greatly increased.

Abstract: A method of producing a new high Tc superconducting material using fullerene molecules as artificial pinning sites for any magnetic flux that may enter the material.

Abstract: A high current amplifier, three terminal device, comprising a Josephson tunnel junction and a Schottky diode is configured so that the Josephson junction and Schottky diode share a common base electrode which is made very thin. Electrons which cross the Schottky barrier are supplied to the Josephson junction to obtain the amplified output current.

Abstract: Magnetic flux concentrating materials are introduced in superconducting moelectronic devices and circuits as a method and means for fabrication of more compact, higher speed superconducting microelectronic devices and circuits.

Abstract: A method and material for coating metal surfaces which prevents disbonding f the coating and metal surface. A polymer coating material has high molecular weight cations added thereto and can be used to paint steel or other metal surfaces subject to cathodic ionization.

Abstract: A high intake, defined excitation, vertical profiling survey bioluminescence bathyphotometer system designed to measure, from a statistically significant sample with a calibrated hydromechanical stimulus, (1) the bioluminescence of phytoplankton and zooplankton organisms in the oceanic water column to depths of 400 meters in absolute units of photons per second per volume (intensity) or photons per volume (total flux), (2) the concentration of bioluminescent population in flashes per volume, (3) the average light intensity per bioluminescent event, and (4) population flash dynamics.

Abstract: A broadband laser which can be electronically tuned to a narrow line by insertion of a frequency selective element in the laser cavity.

Abstract: A method and apparatus for retarding the pitting of aluminum by coating the luminum with a film which includes molybdenium oxide.The aluminum material is preexposed to a molybdate solution before anadizing in a sodium tartrate solution.

Abstract: A mixed polymer electrolyte and a solid rechargeable battery which uses a solid mixed polymer electrolyte of poly[bis(methoxyethoxyethoxide)phosphazene].
