Title: Masahide Fujita: Innovator in Microprocessor Technology

Introduction

Masahide Fujita is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of microprocessor technology, holding a total of 3 patents. His work focuses on enhancing the reliability and functionality of microprocessors in various applications.

Latest Patents

Fujita's latest patents include a microprocessor runaway monitoring control circuit. This innovative circuit allows for the safe and cost-effective self-diagnosis of a watchdog timer (WDT) during the operation of a microprocessor (CPU). The system supplies first and second watchdog clearing signals to the respective watchdog timers. When both signals cease, the microprocessor is reset through a logical connector circuit. Additionally, the microprocessor features failure diagnosing means that intentionally halts the first watchdog clearing signal to assess the response of the first watchdog timer based on a monitor signal. This process enables diagnosis without interrupting the microprocessor's operation.

Another notable patent is a vehicle controlling apparatus designed to ensure the normal operation and restart of a microprocessor when it experiences runaway conditions. This system includes various on-vehicle loads driven by the CPU, a watchdog timer for monitoring, and a memory element that stores reset output generation. The memory element can be reset by cutting off or reclosing the power switch, allowing the electronic apparatus to return to a normal state.
