Statistical Methods for Ultrasonic Data (Analysis Using R Language and Environment)

Technology to control low-frequency resonance phenomena and high-frequency nonlinear phenomena.

The Ultrasonic System Research Institute has developed a technology to control the nonlinear vibration phenomena of surface acoustic waves using ultrasonic oscillation control technology. By confirming the basic acoustic characteristics of ultrasonic waves (response characteristics, propagation characteristics) for various targets (water tanks, transducers, probes, fixtures, objects, etc.), we realize ultrasonic propagation states tailored to specific applications through oscillation control. By setting the oscillation conditions for sweep oscillation and pulse oscillation using two or more types of nonlinear resonant ultrasonic oscillation control probes, we dynamically control high sound pressure level resonance phenomena and the generation of harmonics (nonlinear phenomena of the 10th order and above), achieving high-frequency propagation states of over 100 MHz. Note: Precision cleaning examples Sweep oscillation: 70 kHz to 15 MHz, 15 W Pulse oscillation: 13 MHz, 8 W This technology is an efficient method for utilizing low-power ultrasonic oscillation.

Ultrasound consulting specialized in measurement and analysis of ultrasonic propagation conditions.

The Ultrasonic System Research Institute conducts consulting related to ultrasonic applications using a technology that measures, analyzes, and evaluates the propagation state of ultrasound, applying feedback analysis techniques based on multivariate autoregressive models. By organizing the measurements, analyses, and results obtained using ultrasonic testers in chronological order, we establish and confirm new evaluation criteria (parameters) that indicate the appropriate ultrasonic state for specific purposes. Note: - Nonlinear characteristics (dynamic characteristics of acoustic flow) - Response characteristics - Fluctuation characteristics - Effects due to interactions By developing original measurement and analysis methods that consider the acoustic properties of the target object and surface elastic waves, we deepen our understanding of the relationships between various effects related to vibration phenomena, drawing on the principles of statistical mathematics. As a result, there is an increasing number of cases demonstrating that new nonlinear parameters are highly effective regarding the propagation state of ultrasound and the surface of the target object. In particular, evaluation cases related to cleaning, processing, and surface treatment effects lead to successful control and improvement based on good confirmations.

Ultrasonic control technology based on the classification of nonlinear phenomena in which ultrasonic vibrations propagate.

The Ultrasonic System Research Institute has developed a classification method for the phenomenon of ultrasonic vibration propagation by analyzing measurement data of ultrasonic propagation states using bispectral analysis. The method developed in this instance estimates the linear and nonlinear resonance effects based on the dynamic characteristics (changes in nonlinear phenomena) of the main frequencies (power spectrum) related to the ultrasonic propagation state. From previous data analysis, we have been able to classify effective utilization methods into the following four types: 1: Linear type 2: Nonlinear type 3: Mixed type 4: Variable type There are numerous successful cases of device development and control settings based on each of the above types. This technology will be offered as a consulting service. Ultrasonic propagation characteristics: 1) Detection of vibration modes (changes in autocorrelation) 2) Detection of nonlinear phenomena (changes in bispectrum) 3) Detection of response characteristics (analysis of impulse response) 4) Detection of interactions (analysis of power contribution rates) Note: The following tools will be used for analysis.

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

The Ultrasonic System Research Institute is developing technologies related to effective "measurement, analysis, and evaluation methods" using a <statistical approach> concerning the utilization of ultrasound. <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. - From "Statistics in Science" edited by Hirotsugu Akaike <About Models> Models are constructed with the aim of effectively advancing understanding, prediction, and control regarding the subject. Building an accurate model is difficult, and the examination is always conducted in a form that appropriately "rounds off" the complexity of the subject. In this sense, the process of constructing or building a model requires statistical thinking. <About the Relationship Between Models and Current Systems> (Points to Consider When Reflecting) 1) It is necessary to consider that preconceived notions and experiences may not be correct. 2) To think about the essence of a model, I believe it is effective to utilize category theory.

Our wireless nurse call linked set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed area, alleviating concerns about tripping or falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations far from the nurse call outlet, allowing for more flexible equipment placement.

A truck berth is a space in a logistics warehouse where trucks can be parked to load and unload goods. By installing sensors in the truck berth to display the occupancy status, it is possible to quickly guide trucks to available spaces. Additionally, sharing the occupancy status with warehouse workers allows for a swift start to loading and unloading, improving overall productivity and reducing truck waiting times. 【Target Products】 - Occupancy detection sensor HM-UX2/UW2 (ceiling-mounted, ultrasonic type) ■ Benefits of Implementation Benefit 1: The HM-UX2 can be installed at high positions without height restrictions. Benefit 2: By setting the detection distance higher than a person's height, false detections caused by people are reduced. Benefit 3: The HM-UX2 is not affected by the floor surface, eliminating false detections caused by small stones or unevenness on the floor. Benefit 4: For locations with many parking spaces, the communication-type ultrasonic sensor HM-UW2 is recommended.
