Title: Yushi Nagasaka: Pioneering Innovations in Flow Rate Measurement and Mobile Communication

Introduction:

Yushi Nagasaka, a prolific inventor and researcher based in Yokohama, Japan, has made significant contributions to the fields of flow rate measurement and mobile communication. With an astonishing number of 100 patents under his belt, Nagasaka's ingenuity and dedication have propelled the progress of these domains. This article aims to shed light on some of his most recent patents and delve into his contributions in collaboration with his coworkers at KYOCERA Corporation.

Flow Rate Innovations:

Among his latest patents, Nagasaka has designed a series of groundbreaking inventions in the field of flow rate measurement. Notable contributions include the development of a flow rate-velocity sensor device and a flow rate-velocity calculation method. These inventions integrate advanced technologies to accurately calculate flow rate and flow velocity, utilizing a light receiver and emitter system within a package. The inclusion of a correction unit and arithmetic unit further enhance the accuracy of the calculations.

The flow rate-velocity sensor device, comprising a transparent substrate and a flow rate-velocity calculator, exemplifies Nagasaka's expertise in harnessing innovative solutions to measure flow rates. The receiver in the calculator processes data acquired from a power spectrum, which is then corrected by the correction unit to calculate a more accurate second power spectrum. Finally, the arithmetic unit utilizes the second power spectrum to calculate the flow rate or flow velocity, which can be transmitted to an external unit via the transmitter.

Contributions in Mobile Communication:

In addition to his accomplishments in flow rate measurement, Nagasaka has also made impactful contributions to the field of mobile communication. One of his patents focuses on a user terminal and mobile communication method. This invention allows user equipment to transmit a random access preamble to a cell and subsequently receive a random access response from the cell, indicating the rejection of a Radio Resource Control (RRC) connection to the cell. This innovative method enhances the efficiency and reliability of mobile communications.
