Title: The Innovations of Yuichiro Yoshimura

Introduction: Yuichiro Yoshimura is a renowned inventor based in Yokohama, Japan, known for his significant contributions to the field of coordinate input technology. With an impressive portfolio of 73 patents, Yoshimura has established himself as a pivotal figure in innovation and design.

Latest Patents: Among his latest innovations are two advanced coordinate input apparatuses.

The first apparatus features a light projecting unit designed to project light parallelly to an effective coordinate input region. It includes a reflection unit to retroreflect the projected light and a light receiving unit that captures light from either the projection or reflection units. The system is equipped with a moving unit that adjusts the position of the light units to ensure an optimal light amount for precise calculation of pointed positions within the effective coordinate input region.

The second apparatus introduces a dual housing design, where each housing incorporates at least two sensor units. These units consist of one light projecting unit and one light receiving unit each. Calculations for the pointed position in the effective coordinate input region are based on the variations in light amount distribution gathered from the receiving units in both housings. The design allows for a field range that remains almost parallel to the effective coordinate input region, optimizing accuracy in directionality and measurement.

Career Highlights: Yuichiro Yoshimura has had a distinguished career, during which he has contributed to several pioneering projects at leading companies.
