Abstract: PROBLEM TO BE SOLVED: To provide an improved control system for semiactive suspension, for easily adaptable to the necessity and requirement of a user (a vehicle manufacture), and quickly responding to a specific operating condition. SOLUTION: A vehicle is equipped with at least one semiactive suspension 5 arranged between a vehicle body and a wheel, and having an attenuation coefficient variable by a method controlled by an actuator controlled by a control device 18. The device 18 is equipped with: an acceleration measuring sensor 15 for producing the acceleration signal of a vehicle, a potentiometer 16 for producing a suspension position signal, a signal adjusting unit 21 for operating vehicle and attenuation speeds, a fuzzy control unit 23 for operating the successive position of the actuator based on the vehicle and attenuation speeds, and a drive unit 21 for producing a control signal S1 for the actuator.

Abstract: PURPOSE: To attain noise reduction through a filter for filtering only the noise- containing signal sections in digital video signals. CONSTITUTION: Each circuit means is operated by a fuzzy logic and provided with inference circuits (look-up tables) C1 and C2 and digital subtracters S1-S4. Each subtracter has an input terminal and is provided for receiving an individual digital video signal for reporting information concerning the pixel to be processed. The number of circuit means included in a filter 1 depends on the size of an image to be processed, and secondly, depends on the number of directions under the operation of a line operator. While using fuzzy type logic rules, a noise calculation circuit 4 compares trigger levels determined in the circuits C1 and C2 with such a trigger level. Thus, noise contained in the digital video signal are reduced effectively.

Abstract: PURPOSE: To provide high resolution of video and to eliminate the defects of conventional techniques by providing a calculation block which is connected to an input terminal and operated by a fuzzy-logic based processing method and which executes a switch between at least two different interpolation processing methods. CONSTITUTION: For a TV signal scanning converting device 1, luminance/ chrominance signals CFy and CFuv and signals PFy and PFuv corresponding to image fields are inputted to an interface(IF) 2. The IF 2 is operated with a fuzzy logic and supplies TV signals components Xy and Piy to input terminals Pi and X of a filtering block 3. A calculation block CALC1 is operated with a fuzzy logic processing method, receives a luminance component Y and detects the front and motion of a TV signal, while utilizing information in two continuous image fields. On the other hand, an arithmetic block 5 inputs an average parameter, which is calculated based on pixels (Pi , Pj and x) of image fields, to the calculation block CALC1 . A block MAX calculates and outputs the peak value of plural signals to be inputted.
