Introduction

Masahiro Tokunaga is a prominent inventor based in Nagoya, Japan. He has made significant contributions to the field of vehicle technology, holding three patents that showcase his innovative spirit and technical expertise. His work focuses on enhancing vehicle functionality and aesthetics through advanced antenna and power supply designs.

Latest Patents

One of Tokunaga's latest patents is a vehicle antenna that integrates multiple functionalities. This antenna incorporates a GPS antenna, a radio wave beacon antenna for VICS/automatic rate, and an optical beacon antenna. These components are cleverly housed between the room mirror and a cover, forming a unified structure. This design allows for signal transmission and reception through the vehicle's windshield, eliminating the need for separate installations on the vehicle body and instrumental panel. As a result, the interior appearance of the vehicle is significantly improved. Additionally, the antenna's placement in the room mirror keeps it out of the driver's direct line of sight, preventing any interference with driving operations.

Another notable patent is a power supply device for vehicles. This device is strategically positioned between a car battery and various load units, such as a light control unit. It utilizes a multi-signal line to monitor the consumption current of the load units. By comparing this current with the supplying current from the battery, the power supply unit can detect anomalies, such as a rare short circuit, and interrupt the current supply if necessary. This innovation enhances vehicle safety and reliability.
