Abstract: A system for determining vessel fill percentages using sensor technologies. The system receives a sensor type selection through a graphical user interface at a client device, displays a request for vessel configuration information based on the selection, and configures a lookup table using the received configuration data. When measurement data is received from the sensor device, the system determines the vessel's fill percentage by applying the lookup table to transform raw sensor readings into accurate fill levels, then displays the fill percentage with a vessel identifier. The system accommodates various vessel shapes, dimensions, and configuration parameters including strapping charts, while supporting multiple measurement data types such as distance, pressure, temperature, voltage, current, and magnetic flux. This unified framework enables standardized monitoring across vessel types through a single interface.

Abstract: A system, apparatus, method, algorithm and/or device (collectively, “system”) for non-contact or contactless ultrasound viscoelastic spectroscopy measures the viscoelastic properties of soft matter through exerting modulated ultrasound pressure waves, so called stress signals and measuring the material deformation, so called strain imaging, over a wide range of frequencies, and may be applied to various fields including but not limited to material science, polymer designing, tissue engineering, cancer drug development and/or biological tissue assessment for disease diagnosis and prognosis. By measuring the elastic and viscous moduli, the phase difference between them, and Poisson's ratio over a wide range of frequencies, this allows for non-destructive tests on soft matter such as biological tissue, by ultrasound probes.
