Latest Patents

Hisashi Izumi held a patent for a "Method and device for controlling a shock absorber." This invention includes a shock absorber that comprises a device for detecting the position and velocity of a moving object. The movement mechanism includes a movable part, means for detecting contact between the movable part and the object, and means for detecting the displacement value of the movable part. The control device utilizes information from the position and velocity detecting device to manage the movement mechanism. This allows the movable part to follow the course of the object and move in the same direction at a velocity corresponding to the object's speed. Additionally, the control device reduces the velocity of the movable part based on a predetermined deceleration pattern upon contact with the object. It also executes positioning control to stop the movable part at a predetermined position when the displacement value reaches a specified threshold.
