The textured die surface can be formed using direct metal deposition of a hard material, harder than the existing die surfaces, on the existing die base material to achieve an engineered textured surface. The textured die surface optimizes the performance of the die by enabling longer die life, higher coefficients of friction between the mating binder surfaces and reduction of wrinkles and stringers typically caused by draw and lock beads in the draw forming process.

Abstract: A method for monitoring the capability of a source container comprising liquid or solid source material to produce vaporized source material comprises extracting vaporized source material from the source container. The source container is then isolated and a property indicative of the partial pressure of the vaporized source material is then measured as a function of time. The partial pressure (or property indicative thereof) as a function of time is compared with a reference partial pressure as a function of time. An alarm is generated when the difference between the measured property (indicative of partial pressure) as a function of time and the reference property value as a function of time is larger than a predetermined property difference limit. The property can be, for example, overall pressure or source material concentration in the gas phase.

Abstract: The present invention provides a method and system for detecting low levels of arsine in the presence of varying humidity levels. The present invention incorporates a moisture filter that absorbs and desorbs water as humidity levels change onto an arsine detector. This moisture filter may take the form of a solid tablet formed of a porous, hydrophilic material with a series of small holes therein. The walls of the holes absorb and desorb water as the humidity changes while permitting arsine to pass through unobstructed. Since the electrochemical current responds to the change in the water but the oxidation of arsines responds to the absolute concentration, the effect is that the signal to noise ration is improved by the presence of the moisture filter.

Abstract: A gas monitoring device for monitoring gas levels within a chamber is provided. The gas monitoring device includes a housing having a probe with a sensor disposed on the probe. The probe extends through the housing and into a chamber such that the sensor is within the chamber. The housing includes a first passageway disposed about the probe and second passageway disposed about the first passageway. During operation of the gas monitoring device, a temperature adjusting medium enters the second passageway through an inlet of the housing and then enters into the first passageway via the second passageway. As the temperature adjusting medium travels through the first passageway, the temperature adjusting medium adjusts the temperature of the probe. The temperature adjusting medium adjusts the temperature of the probe through thermal conduction. As the temperature of the probe adjusts, the temperature of the sensor also adjusts through thermal conduction.

Abstract: The present feature of the invention comprises a method and apparatus for determining cylinder ID. When a cylinder is compressed, the resistance increases across the spark plug gap. Thus, if a spark coil is only partially charged before activation of the spark, the air gap is not broken down and no ignition occurs in the cylinder in compression. The failure of a spark plug to spark is reflected in the ionization signal. In a preferred embodiment, the dwell time is selected so that the spark plug located in a cylinder that is not in compression will spark, while a spark plug in a cylinder that is in compression will not. The cylinder in compression will output an ionization signal with a shorter duration than a cylinder not in compression. In a preferred embodiment, two methods are used to calculate the duration of the spark, edge detection and integration.

Abstract: An ignition coil, spark plug, and pressure sense assembly for an internal combustion engine are, in a preferred embodiment, integrated into a single assembly and mounted directly on a plug hole of an internal combustion engine. A pressure sense assembly is welded to a spark plug shell which serves as a pressure member. The pressure sense assembly includes a base plate onto which first and second pairs of strain gauges are printed using a thick film ink process (piezoresistive) in a full bridge arrangement. The geometry of the base plate and the fashion in which it is welded to the shell allow one pair of the gauges to function as strain sensing elements while the other pair can function for temperature compensation. Changes in the pressure in the combustion chamber deform the shell, causing a corresponding change in the bridge producing the pressure signal.

Monitoring over a period of time and appropriate conversion allows accurate assessment of even permeation rates measured as very low fractions of a gram of water per square meter per day.

Abstract: The present invention relates to a method and assembly for leak detection in a plasma system. The invention can accomplish not only leak detection, but also leak location while maintaining a plasma within the plasma system. Leak detection for the invention is achieved by obtaining spectral data of the plasma at one or more times while maintaining the plasma within the plasma system and comparing the same to predetermined spectral data of air. Upon a determination that air is present within the plasma system, one or more external surfaces of the plasma system are exposed to a test gas and the spectral data of the plasma is analyzed after each exposure to determine if the test gas is present in the system. If the test gas is present, a determination can be made that the particular external surface to which the test gas was applied is a leak location.

Abstract: An apparatus and method of analyzing a sample to be scanned within a hermetically sealed housing of an atomic force microscope (AFM) while the interior of the housing is maintained at one of a number of various environmental conditions. The AFM includes an XYZ stage assembly on which a sample holder supporting the sample may be releasably positioned. The stage assembly allows for the manipulation of the sample and sample holder in the X, Y and Z axes without disturbing any environmental condition present within the chamber due to the hermetic seal maintained between the stage assembly and the AFM during the motion of the stage assembly. The ability of the stage assembly to manipulate the sample in each of the three directions while the sample is enclosed within the AFM also allows the AFM to compensate for non-parallel scanning planes and for drift in all three directions occurring in the sample because of the different environmental conditions in which the sample may be scanned.
