Title: Toshiaki Senda: Innovator in Coordinate Input Systems
Introduction
Toshiaki Senda is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of coordinate input systems, holding a total of 9 patents. His innovative work has paved the way for advancements in electronic input technologies.
Latest Patents
One of Senda's latest patents is a coordinate input system that features a tablet composed of an X-direction loop coil assembly and a Y-direction loop coil assembly. This system utilizes an input pen equipped with a tuning circuit, which has a variable tuning frequency around a predetermined frequency. The system is designed to detect X- and Y-coordinate values based on the input from the pen. Additionally, it includes a phase detecting function that monitors changes in the tuning frequency, allowing for precise computation of the detected coordinate point. This computation is proportional to the pressure applied by the pen on the tablet.
Another significant patent is for an electronic blackboard system marker and eraser. This invention determines which of several objects is near a coil by utilizing tuned circuits with different resonant frequencies. The system supplies AC energy at these frequencies to the coil, and the tuned circuit of the object that resonates with the supplied frequency causes a change in the current flowing in the coil. This change is then sensed, allowing the system to identify the specific object based on the resonant frequency.
