Title: Joo Hoon Lee: Innovator in Position Detection Technology
Introduction
Joo Hoon Lee 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
Among his latest patents is a position detector that includes a coil functioning as a sensor. This device features a transfer coil that transfers an alternating magnetic field based on a transfer signal to a position indicator. Additionally, it incorporates a signal processing circuit connected to the coil, which detects a pen signal generated by the position indicator. The circuit generates a transfer signal with a frequency based on the frequency information of the detected pen signal and transfers this signal to the transfer coil.
Another significant patent involves a method executed by a sensor controller of an electromagnetic resonance system. This method aims to improve the signal-to-noise (S/N) ratio of a pen signal received in a sensor controller. It achieves this without decreasing the frequency of position detection or increasing the circuit scale of the sensor controller. The method connects three loop coils in different connection modes for each pen signal detection period, allowing for the separate acquisition of pen signal levels corresponding to each loop coil.
