Title: **Hiroyuki Tobari: Innovator in Tire Wear Condition Detection**

Introduction

Hiroyuki Tobari is a distinguished inventor based in Tokyo, Japan. Known for his contributions to tire technology, he holds two patents that exemplify his innovative approach to detecting tire wear conditions, enhancing safety and efficiency in vehicles.

Latest Patents

Tobari's most recent patents include a **Wear-condition-sensing device** and a **Tire wear state detection device using waveform data**. The wear-condition-sensing device employs an element that generates voltage based on the deformation of the tread portion during tire rotation. This device features a voltage detection unit that monitors the generated voltage and includes a storage area to keep waveform data over time. A calculation unit processes this data to calculate an index value for voltage change, while a determination unit assesses the wear progress by comparing this index to reference information.

The tire wear state detection device expands on this concept by integrating a speed detection unit that tracks vehicle or tire rotation speed. This enhancement allows for a comprehensive analysis, storing waveform data alongside speed metrics. With a focus on calculating the frequency of exceeding predetermined threshold values within specific speed ranges, this device effectively determines the tread wear progress based on calculated exceedances.
