AI Technical Summary

Benefits of technology

This patented technology allows for accurate measurements over long distances without damaging or affecting any part inside it. Its technical benefits include being able to measure very small parts accurately while also having good stability when used by different types of machines such as machining tools. Additionally, this technology uses an apparatus called a coupling agent circulator (CAC) with multiple layers filters, allowing for effective cleanup after use. Overall, these technologies provide advanced solutions for measuring materials' properties within complex structures like walls made from concrete material.

Problems solved by technology

This patented technical problem addressed by this patents relates to accurately controlling the residual thickness (the amount left behind) during the production of large diameter tanks used in space propulsion systems like rockets. Current solutions involve manually checking each part individually but they may result in inconsistencies between different measurements. There is also no current solution available for precision and automation because these techniques require expensive machinery tools and complex controls.
