摘要： In a device for removing inverter noise, a pair of bus bars extending in parallel are grounded via a pair of capacitors. The capacitors are connected to the bus bars and to a grounding terminal at positions symmetrical to the pair of bus bars. Therefore, the inductance components are balanced from the source of noise to the grounded point, and impedance components are decreased from the two bus bars to a point grounded through the capacitors, making it possible to effectively remove high-frequency noise on the DC bus line of the inverter without requiring a large amount of space.

摘要： A process involves collecting data relating to a particular condition and parsing the data from an original set of variables into subsets. For each subset defined, Mahalanobis distances are computed for known normal and abnormal values and the square root of these Mahalanobis distances is computed. A multiple Mahalanobis distance is calculated based upon the square root of Mahalanobis distances. Signal to noise ratios are obtained for each run of an orthogonal array in order to identify important subsets. This process has applications in identifying important variables or combinations thereof from a large number of potential contributors to a condition. The multidimensional system is robust and performs predictive data analysis well even when there are incidences of multi-collinearity and variables with zero standard deviations in reference group or unit space. Separate methods are provided: adjoint matrix Gram-Schmidt's method for multi-collinearity problems, and modified Gram-Schmidt method for the cases where there are variables with zero standard deviation to achieve data analysis.
