Title: Yuichiroh Yoshimura: Innovator in Coordinate Input Technology
Introduction
Yuichiroh Yoshimura is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of coordinate input technology, holding a total of 2 patents. His work focuses on enhancing the accuracy and efficiency of input devices, particularly through innovative designs that utilize vibration technology.
Latest Patents
Yoshimura's latest patents include a coordinate input apparatus and a wireless input pen. The coordinate input apparatus determines the coordinates of contact of a vibration pen with a vibration transmission plate by detecting vibrations from the pen through a vibration sensor. Constants required for measurement are generated in a constant determination circuit based on vibration cycle measurements. This circuit measures the cycle of the detected vibrations from the vibration sensor using the determined constants. The automatic determination of constants eliminates inaccuracies due to component variations, thereby reducing production costs and maintenance.
The second patent, a coordinate input apparatus with a wireless vibrating input pen, features a pen that alternately generates vibrations at two different frequencies. A vibration transmitting member transmits these vibrations, while multiple vibration detectors detect the transmitted vibrations. Processing circuitry derives at least one coordinate of the position of the vibrating input pen based on the transmission delay time between the detected vibrations. This design eliminates the need for transmission and reception of timing information between the vibrating input pen and the main body of the apparatus, allowing for a truly wireless experience.
