    摘要: In a tire air pressure estimation based upon vibration components extractedrom a vehicle wheel speed signal, when the vehicle is a driven vehicle wheel, the precision of estimation is improved by canceling the components of vibration due to the resonance of the drive system from the vibration components based upon which the estimation calculation is made. The vibration components due to the resonance of the drive system can be canceled by canceling those vibration components extracted from the vehicle wheel speed signal which are the same in the phase between left and right driven vehicle wheels. When the tire air pressure of one of a pair of left and right driven vehicle wheels is lower than that of the other, the lower tire air pressure is more correctly estimated. Therefore, the higher tire air pressure may be estimated according to the lower tire air pressure against the drive system resonance.

    摘要: A method for X-ray computed tomography includes a process for rotating around an object an X-ray source for applying a cone-beam X ray and a scanner having a two-dimensional X-ray detector mounted thereon for deriving projection data and a process for preparing a geometric distortion correction table for correcting an image geometric distortion of the two-dimensional X-ray detector for the projection data, for reconstructing a distribution of X-ray attenuation coefficients of the object from said corrected projection data. The method further includes a process for calculating a function for evaluating the correction table, a process for comparing the calculated value with a threshold value, a process for correcting the correction table through the interpolation based on the compared result, a process for correcting an image geometric distortion of the projection data by using the corrected table, a process for detecting a location of a view field boundary of the detector from the distortion-corrected projection data, and a process for generating the projection data of a predetermined width from the detected location of the view field boundary through the effect of the extrapolation. The method operates to reconstruct a distribution of X-ray attenuation coefficients of the object from the extrapolated projection data.
