Abstract: Carbon nanotubes are formed on projections on a substrate. A metal, such as nickel is deposited on the substrate with optional platforms, and heated to form the projections. Carbon nanotubes are formed from the projections by heating in an ethylene, methane or CO atmosphere. A heat sensor is also formed proximate the carbon nanotubes. When exposed to IR radiation, the heat sensor detects changes in temperature representative of the IR radiation. In a gas sensor, a thermally isolated area, such as a pixel is formed on a substrate with an integrated heater. A pair of conductors each have a portion adjacent a portion of the other conductor with projections formed on the adjacent portions of the conductors. Multiple carbon nanotubes are formed between the conductors from one projection to another. IV characteristics of the nanotubes are measured between the conductors in the presence of a gas to be detected.

Abstract: A control system coupled to a pressure sensor calibrates the pressure sensor. The control system may measure a plurality of capacitance values at a plurality of corresponding applied voltages to compare the values with a first calibration mechanism generated by sample pressure sensors in a comparison. A final calibration mechanism may be generated by adjusting the first calibration mechanism in response to the comparison. The unknown differential pressure may be applied to a diaphragm of the pressure sensor. A capacitance value at the unknown differential pressure may then be measured. Using the final calibration mechanism, the differential pressure at the measured capacitance value may be retrieved.

Abstract: An apparatus having scattering and multi-color fluorescence detecting, analyzing and identification capabilities of blood or other fluids of interest. The sample to be tested may be entered in a disposable microfluidic cartridge which in turn is insertable in a hand-holdable or implantable miniaturized and portable cytometer instrument. This cytometer has significant application in biological warfare agent detection, hematology and other clinical and research fields.

Abstract: A multiplexed set of light sources having outputs of light with various wavelengths which are combined into one beam. The beam may impinge a particle in a flow channel of a cytometer. The light leaving the flow channel may be sensed by a detector and the light distinguished according to wavelength.

Abstract: An anchoring apparatus for anchoring pneumatic watercraft such as an inflatable boat, raft, floating air mattress, recreational inner tube, floating lounge chair, and the like. The anchoring apparatus includes a generally hollow anchor portion having a closable opening. The closable opening is configured for the removable introduction of weighing material in the anchor portion. An anchor line is secured to the anchor portion and extends therefrom. The anchor line is removably securable to a pneumatic watercraft.

Abstract: Novel method and apparatus are disclosed for dielectrically drying green ceramic or wet honeycomb structures, by rotating such structures about their longitudinal axis between a pair of parallel dielectric electrodes and simultaneously blowing heated air through the longitudinal cells of the honeycomb structure. Preferably the dielectric electrodes are oriented parallel with the longitudinal axis of the honeycomb structure, and the rotation thereof between the electrodes accordingly results in a more uniform energy transfer to the honeycomb structure by leveling out the non-uniformities and variations in the dielectric field.

Abstract: The present invention features a process and apparatus for fabricating ceramic substrates. The apparatus comprises an extruder of the ram or screw type for forcing the ceramic materials through a die to form a log. After leaving the extrusion die, the log enters a conveyor apparatus. The log is conveyed over, and supported upon, a gaseous fluid (air) bearing surface of the conveyor apparatus, until it reaches a dryer carrier. The conveyor apparatus features a support surface for carrying the ceramic materials. The support surface has a plurality of apertures through which the gaseous fluid (air) is directed for supporting the moving log. About the support surface is disposed a mantle for confining the gaseous fluid (air) about the rapidly drying ceramic log. The gaseous fluid (air) is maintained at a relative humidity of approximately between 85 to 97%, and preferably within an approximate range of between 90 and 95%.

Abstract: The present invention relates, in general, to optical transducers, and more particularly to optical transducers utilizing the Faraday effect and responsive to changes in a magnetic field produced by a target. These changes in magnetic field produce a modulation in the light passing through a ferrite crystal, and this modulation can be used to measure mechanical motion, proximity, and related parameters.

Abstract: The burn-in of the refractory lining or of the refractory component of a tuyere-containing bottom plug in a bottom-blown oxygen steelmaking converter is effected with the plug in place by passing oxygen and a gaseous hydrocarbon mixed with controlled amounts of neutral gas through the respective concentric passages in tuyeres contained in the plug. The described method can be employed to burn-in a bottom plug installed in a converter together with a newly installed refractory converter lining or to burn in a newly installed bottom plug in an existing converter lining.
