Introduction

Yuudai Yamashita, based in Tokyo, Japan, is a noteworthy inventor with a portfolio of nine patents to his name. His work primarily focuses on innovations in imaging technologies and materials that enhance data input systems.

Latest Patents

Among his latest inventions, one significant patent is the "Pattern Printed Sheet." This innovative sheet includes a substrate and a non-visible light-reflective transparent pattern printed on its surface. The ink used in this transparent pattern incorporates a non-visible light-reflective material capable of selectively reflecting light in the non-visible range. The multilayered structure of the transparent pattern can reflect only a circular polarization component in a predetermined rotation direction concerning the incident light. This design allows the pattern printed sheet to be utilized in coordinate detecting systems, enabling direct hand-writing input on display devices at a reduced weight and cost, while also being mass-producible in large area sheets.

Another notable patent is related to an "Image Reader Incorporated in Electro-Developing Type Camera and Electro-Developing Recording Medium Used Therein." This invention involves an electro-developing recording medium designed with a reference zone that maintains a constant transparency level. This reference zone is critical for preparing correction data, ensuring accurate image pixel signals obtained from optical and electronic readings of developed images. The innovative design incorporates an electrostatic information recording medium along with an electric charge keeping medium, which includes a liquid crystal display with defined reference zones to enhance transparency.
