| 20090254286 | Systems and Methods for Modeling Surface Properties of a Mechanical Component - There is a method for modeling the surface fatigue life of a mechanical component. The method has the following steps: a) modeling the surface fatigue life of the mechanical component on an atomistic scale to form an atomistic model, b) modeling the surface fatigue life of the mechanical component on a mesoscale to form a mesoscale model, c) modeling the surface fatigue life of the mechanical component on a macroscale to form a macroscale model, and d) testing the surface fatigue life of the mechanical component. Feedback from the macroscale model is employed at least once to validate the atomistic model. Feedback from the macroscale model is employed at least once to validate the mesoscale model. Feedback from the testing is employed at least once to validate the macroscale model. There is also an interactive, multiscale model for prediction surface fatigue life or degradation rate for a mechanical component. | 10-08-2009 |

| 20090045351 | SENSOR SYSTEM WITH SURFACE-PLASMON-POLARITON (SPP) ENHANCED SELECTIVE FLUORESCENCE EXCITATION AND METHOD - In a sensor system, an active sensor chip includes an array of periodically-patterned dielectric active sensor patches of different periodicities and geometries formed on a metal film. A specimen under study is positioned on each patch, and the active sensor chip is interrogated by illumination the patches in a predetermined sequence to result in a fluorescence response from each patch enhanced by SPP. The intensity of the fluorescence response is controlled by varying the wavelength, incidence angle, azimuthal orientation and polarization direction of the excitation light beam as the function of the periodicity of the illuminated patch. The system is compatible with commercial fluorescence microscopes and scanned laser interrogation systems. | 02-19-2009 |
