Abstract: A vehicle control device includes a processor. The processor calculates an instruction value of an operation request for controlling an operation of an actuator mounted on a vehicle based on a motion request from an application. The processor executes feedback control on the instruction value using a deviation between the motion request and a motion result of the vehicle that is calculated based on one of detection values of four wheel velocity sensors. The processor calculates the motion result in the feedback control based on a detection value indicating the second largest vehicle body velocity among the vehicle body velocities indicated by the detection values of the four wheel velocity sensors when the vehicle is braked.

Abstract: A fluorescent material arranged under an environment of temperature objective for measurement is excited by irradiating red color light or infrared rays, then fluorescent light generated from the fluorescent material is received by an optical sensor thus the temperature of the fluorescent material is measured from an output of the optical sensor on the basis of the correlation between a fluorescent characteristic of the fluorescent material and temperature.

Abstract: A digital control color illumination system is disclosed for use in a visual system of an industrial robot or the like. This system comprises: image memories to store the color data regarding illumination patterns of three primary colors of red, green, and blue; video signal producing circuits each for reading out the data from the image memory and converting it to the video signal indicative of the illumination pattern; video projectors each for projecting the light of the illumination pattern represented by the video signal onto an object to be illuminated; and a color TV camera to pick up the object image. The image data picked up is processed by a computer system to produce the data which is stored into the image memories. With this illumination system, the scanning of the illumination patterns, and the change, adjustment, storage, and the like of the illumination patterns can be executed by software in accordance with programs preliminarily stored in the program memory in the computer system.

Abstract: A color sensing device comprising four photo-electric transducers formed on a semiconductor substrate, an interference filter provided on the light receiving face of each transducer, a colored filter for selecting a specified transmission band of the interference filter, and three electrodes for delivering electric signals from the transducers individually, one of the electrodes being provided for two of the transducers in common. The transducers each have the area of its light receiving face so determined as to exhibit spectral sensitivity characteristics matching the color matching function of the CIE (Commission Internationale de l'Eclairage) XYZ colorimetric system.
