Abstract: The present disclosure is directed to a method of tool matching that employs an auto-learning feedback loop to update a library of key parameters. According to the method, measurements are performed on a control wafer to collect a set of parameters associated with the process/analysis tool that is being matched. When deviated parameters correlate to a correctable tool condition (i.e. a tool matching event), the parameters are added to the library of key parameters. These key or critical parameters may be monitored on a more frequent basis to identify deviations that have a strong likelihood of matching with a correctable tool condition. The tool matching methodology advantageously allows for monitoring of an automatically updated list of key parameters instead of needing to look at the full set of parameters collected from a control wafer each time. As such, tool matching can be performed on a more frequent basis.

Abstract: Method for determining structural parameters of a railway track having a sensor array, includes measuring vertical and/or lateral irregularities of the rail with the sensor array along the rail, thereby providing signals corresponding to geometrical irregularities at different distance from the wheel-load. A model is provided describing the rail's deflection shape, which is dependent on structural parameters of the rail and on the loads on the rail. The model is stored in a processor where geometrical irregularities are compared under different load influence for generating a measured deflection shape. At least one theoretical rail deflection shape is generated using the model by varying structural parameters and the load in the model. At least one of theoretical deflection shapes is compared with the measured deflection shape for each point of the rail, and the structural parameters of that theoretical deflection shape which best matches the measured deflection shape are determined.

Abstract: A bank angle detection device for a motorcycle includes a bank angle estimator configured to estimate a moving body bank angle ?b and a correcting section configured to estimate a vehicle body bank angle ?f. The bank angle estimator estimates the moving body bank angle ?b that is a gradient of a moving body axial line A1, on the basis of a balance state where a centrifugal force CF acting on a moving body and a gravitational force GF acting on the moving body during cornering are in balance with each other. The correcting section corrects the moving body bank angle ?b on the basis of an inertia force about a longitudinal axis acting on a vehicle body, so as to estimate the vehicle body bank angle ?f that is a gradient of a center of gravity G of the vehicle body with respect to a vertical line.
