To stabilize the effects of cavitation, a statistical perspective is essential.

The Ultrasonic System Research Institute is developing technologies related to effective "measurement, analysis, and evaluation methods" utilizing a <statistical approach> in the field of ultrasonic applications. <About the statistical approach> Statistical mathematics has both abstract and concrete aspects, and through contact with concrete entities, abstract thoughts or methods are developed. This is the characteristic of statistical mathematics. Regarding ultrasonic research, "a statistical perspective is essential for stabilizing the effects of cavitation." <About models> Models are constructed with the aim of effectively advancing understanding, prediction, control, etc., regarding the subject. Constructing an accurate model is difficult, and discussions are always conducted using a suitably "rounded" representation of the complexity of the subject. In that sense, the process of constructing or building a model requires statistical thinking.

Leading to new applications of ultrasound from sound pressure and vibration data of ultrasound.

Application of ultrasonic sound pressure measurement, analysis, and evaluation technology The Ultrasonic System Research Institute has developed a method for the analysis and evaluation of ultrasound (system technology) that applies measurement, analysis, and control technology related to the nonlinearity of ultrasound. Using this technology, we will provide measurement, analysis, and evaluation support for ultrasonic devices. For specific support and costs, please contact us via email. *Comment* Currently, regarding the use of ultrasound, I believe it is very difficult to detect and confirm the optimal ultrasonic state for the intended purpose. Therefore, by incorporating "sound pressure data" into the daily management of ultrasound, we aim to resolve the relationship with the final evaluation state (defect rate, yield, etc.) through the accumulation and analysis of statistical data. By analyzing using time-series data analysis technology, effective improvements have been realized. As a result of continuing such improvements, the number of successful cases using low-output ultrasonic oscillation control has increased. We have been manufacturing and selling our original product: ultrasonic systems (sound pressure measurement analysis, oscillation control) since March 2021.

We are pleased to announce the development of the vehicle passage time prediction system "MS-VPP," which measures the speed of vehicles approaching construction sites using microwave sensors and informs the predicted passage time through signage and tablets. This system will be available to construction contractors starting in November 2025. ■Product Overview - "MS-VPP" detects vehicles approaching construction sites and measures their speed using microwave sensors, displaying the vehicle speed and the predicted passage time at specified locations on signage and tablets. It can also measure and display data for vehicles passing continuously. - The data control panel connected to the microwave sensor transmits the vehicle speed data and calculated passage prediction time via LTE. By utilizing microwave sensors, it enables accurate detection and speed measurement of vehicles even at night or in bad weather, and since data processing occurs on the receiving side without going through the cloud, information can be displayed without any time lag. - As a result, drivers of construction vehicles exiting from construction entrances and workers directing traffic can understand "how many seconds until a vehicle passes near the site entrance," thereby implementing safety measures in areas with poor visibility.
