Title: Innovations of Tatsuru Nakagaki

Introduction

Tatsuru Nakagaki is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of technology, holding a total of 16 patents. His work primarily focuses on mobile communication systems and multi-processor architectures.

Latest Patents

One of Nakagaki's latest patents is for a mobile terminal that includes a reception unit to receive an initial beacon from various communication systems. This beacon contains information necessary for establishing communication according to different methods. The mobile terminal also features a request unit that generates a request using the initial beacon, transmitting it to the communication systems. Additionally, a determination unit assesses the response to the request, identifying the appropriate communication method and frequency band for use in a specific time zone.

Another notable patent is for a multi-processor system that enhances data transmission for writing data into shared memory. This system utilizes a high-speed dedicated line between each processor and the shared memory. When a processor writes to a shared memory space, it notifies an update notification bus, allowing other processors to inhibit access to that address until the write data is sent. This process maintains cache coherency and significantly reduces the time required for acquiring bus use rights.
