Title: **Hirohide Iwase: Innovator in Automotive Shock Absorption Technology**
Introduction
Hirohide Iwase, an accomplished inventor based in Mishima, Japan, has made significant contributions to the automotive industry. With two noteworthy patents, Iwase's innovations focus on enhancing vehicle performance and comfort through advanced shock absorber technology.
Latest Patents
Hirohide Iwase's latest patent, a **Shock Absorber Controller**, introduces a sophisticated mechanism that regulates variable damping forces based on the cycle time and oscillating phase of body vibrations. This innovation enhances vehicle stability by increasing the damping force as the vehicle moves toward its mean position, while maintaining a weaker damping force initially to expedite the return to that position. Iwase has proposed specific criteria to determine this movement toward equilibrium.
Another significant patent is the **Method for Evaluating Surges of Motor Vehicles**, which involves calculating the root mean squares of amplitude produced over designated time frames. This method focuses on the surges within frequency ranges that are easily perceptible to the human senses during vehicle operation. The magnitude of these squares correlates closely with the surges felt by individuals, leading to a better understanding of vehicle dynamics.
