Abstract: A turning control device includes a first processor, a second processor, a third processor, and a fourth processor. The first processor calculates a torque command value based on a difference between a target pinion angle and a pinion angle. The second processor calculates a compensation value compensating resistance of a turning mechanism based on a difference between a target pinion angular velocity and a pinion angular velocity. The third processor limits a variation range of the torque command value based on a limit value of the torque command value and limits a variation range of the compensation value based on a limit value of the compensation value. The fourth processor calculates a turning torque command value by subtracting the compensation value from the torque command value. The third processor changes the limit values based on a traveling state of a vehicle.

Abstract: A region-of-interest (ROI) setting apparatus for respiration monitoring and a respiration monitoring system capable of setting an ROI in an automatic manner. Absolute values of subtractions between every successive two of a plurality of frame images photographed by a CCD camera 2 for a period of time equal to half a respiration period are calculated, then summed and stored. Based on the change information thus calculated and stored, the position and size of each changed region is calculated. Provisional regions are set from the changed regions successively from the greatest to the smallest one thereof. In each of these provisional regions, it is determined whether a gray level histogram indicative of distribution of the number of pixels for respective gray level values includes a twin peak characteristic having twin peaks each equal to or higher than a predetermined value, and whether the area of the corresponding changed region is equal to or greater than a predetermined value.
