  • Patent number: 8527214
    Abstract: A mechanical seal monitoring system and method that measure the wear of seal faces of a mechanical seal where the mechanical seal seals a rotating machine portion from another portion of the machine. The system preferably uses a wear probe movable relative to a rotating seal component so that the wear probe can contact the rotating component. The wear of the seal is preferably determined by the relative movement that is required for the wear probe to contact the rotating component. Preferably, stress waves induced by the rubbing between the probe and the rotating component are detected by a stress-wave sensor, processed by a signal processor, and either displayed to the user numerically or reported to a monitoring computer. A signal intensity comparison method is preferably used to make the detection process insensitive to background noise generated by sources other than the contact of the wear probe and the rotating component.

  • Publication number: 20130211760
    Abstract: Provided are techniques for numerically integrating an intensity distribution function over a numerical aperture in a manner dependent on a determination of whether the numerical aperture spans a Rayleigh singularity. Where a singularity exists, Gaussian quadrature (cubature) is performed using a set of weights and points (nodes) that account for the effect of the Wood anomaly present within the aperture space. The numerical aperture may be divided into subregions separated by curves where the Wood anomaly condition is satisfied. Each subregion is then numerically integrated and a weighted sum of the subregion contributions is the estimate of the integral. Alternatively, generalized Gaussian quadrature (cubature) is performed where an analytical polynomial function which accounts for the effect of the Wood anomaly present within the aperture space is integrated. Points and nodes generated from a fit of the analytical polynomial function are then used for integration of the intensity distribution function.

    Abstract: An improved quality assurance system and method for point-of-care testing are disclosed. The present invention provides quality assurance for laboratory quality tests performed by a blood analysis system or the like at the point of patient care without the need for running liquid-based quality control materials on the analysis system. Quality assurance of a quantitative physiological sample test system is performed without using a quality control sample by monitoring the thermal and temporal stress of a component used with the test system. Alert information is generated that indicates that the component has failed quality assurance when the thermal and temporal stress exceeds a predetermined thermal-temporal stress threshold. Alternatively, the present invention provides quality assurance for laboratory quality tests performed by a blood analysis system or the like at the point of patient care by minimizing the need for running liquid-based quality control materials on the analysis system.

    Abstract: A method is disclosed for localizing product yield variability to a process module. The method includes obtaining fail rate and critical area data for each process module layer in a number of test chips. A variance in a defect density (DD) probability density function (PDF) is determined based on the obtained fail rate and critical area data for each process module layer. A percent contribution from each process module layer to the variance in DD PDF is determined. Based on the determined percent contribution to the variance in DD PDF from each process module layer, one or more process module layers are identified as contributing to the determined variance in the DD PDF. Additionally, a method is provided to assess the impact on product yield due to reduction in the yield variability associated with a particular process module layer.

    Abstract: A method, system and computer program product for generating device fingerprints and authenticating devices uses initial states of internal storage cells after each of a number multiple power cycles for each of a number of device temperatures to generate a device fingerprint. The device fingerprint may include pairs of expected values for each of the internal storage cells and a corresponding probability that the storage cell will assume the expected value. Storage cells that have expected values varying over the multiple temperatures may be excluded from the fingerprint. A device is authenticated by a similarity algorithm that uses a match of the expected values from a known fingerprint with power-up values from an unknown device, weighting the comparisons by the probability for each cell to compute a similarity measure.

    Abstract: Algorithm for reconstructing grating profile in a metrology application is disclosed to numerically solve a volume integral equation for a current density. It employs implicit construction of a vector field that is related to electric field and a current density by a selection of continuous components of vector field being continuous at one or more material boundaries, so as to determine an approximate solution of a current density. The vector field is represented by a finite Fourier series with respect to at least one direction, x, y. Numerically solving volume integral equation comprises determining a component of a current density by convolution of the vector field with a convolution operator, which comprises material and geometric properties of structure in the x, y directions. The current density is represented by a finite Fourier series with respect to x, y directions. Continuous components are extracted using convolution operators acting on electric field and current density.

    Abstract: A method, device and computer program product for determining at least one property of a current (Ip) running through the primary winding of a transformer operating in saturation using an unreliable detected current (Is) running through the secondary winding of the transformer. According to the invention a first reliable extreme point (EP1) of a cycle of the current in the secondary winding is detected and compared with an absolute time reference. Based on the comparison a first property of the current running through the primary winding in the form of the phase angle is then determined.

  • Patent number: 8364302
    Abstract: A semiconductor wafer fabrication metrology method in which process steps are characterized by a change in wafer mass, whereby during fabrication mass is used as a measurable parameter to implement statistical process control on the one or more of process steps. In one aspect, the shape of a measured mass distribution is compared with the shape of a predetermined characteristic mass distribution to monitor the process. An determined empirical relationship between a control variable of the process and the characteristic mass change may enable differences between the measured mass distribution and characteristic mass distribution to provide information about the control variable. In another aspect, the relative position of an individual measured wafer mass change in a current distribution provides information about individual wafer problems independently from general process problems.

    Abstract: A system is provided for improved quality assurance (QA) in remote-access elections by a QA unit that evaluates an election service provider (ESP) that tallies votes, each of which includes a vote-identification number (VIN) and a vote content. The QA unit assures a likelihood that no votes have been deleted, inserted or changed by the ESP. The QA unit does this by allocating QA VINs and voting QA votes and then checking the ESP's report of all VINs included in the tally and the content of all QA votes. The ESP, if unaware of which votes are QA votes and which are voter voters, is prevented from deleting, inserting, or changing votes without risk of detection by the check of the QA votes. The system includes capability of ensuring defined confidence levels for a given quantity of voters and an expected voter turnout by incorporation of a suitable number of QA VINs.
