Title: Hiroshi Mizuhashi: Innovator in Position Detection Technology
Introduction
Hiroshi Mizuhashi is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of position detection technology, holding a total of 3 patents. His work focuses on enhancing the accuracy and efficiency of position detection systems.
Latest Patents
Mizuhashi's latest patents include a position detector, an integrated circuit, and a position detection method. The position detector features a coil that functions as a sensor, which includes a transfer coil that transfers an alternating magnetic field based on a transfer signal to a position indicator. Additionally, a signal processing circuit is connected to the coil, designed to detect a pen signal generated by the position indicator. This circuit generates a transfer signal with a frequency based on the frequency information of the detected pen signal and transfers it to the transfer coil.
The method executed by the sensor controller of the electromagnetic resonance system aims to improve the signal-to-noise (S/N) ratio of the pen signal received in the sensor controller. This is achieved without decreasing the frequency of position detection or increasing the circuit scale of the sensor controller. The method involves connecting three loop coils in different connection modes for each pen signal detection period, allowing for the separate acquisition of the pen signal levels corresponding to each loop coil.
