AI Technical Summary

Benefits of technology

This new technology allows testing an object's behavior during operation on vehicles that use this system. It accurately measures how well these objects are doing compared against existing standards or models based only on their static properties. Additionally, its ability to predict changes over time makes it possible to improve upon future designs without having to rewrite them every few months due to advancements made throughout production processes. Overall, this technology improves efficiency and effectiveness across various industries such as automotive industry, manufacturing, transportation, defense systems, etc., while also providing valuable feedback about the physical attributes of each component within the structure being tested.

Problems solved by technology

This patents describes how improving ride quality (ride) during car designs can improve passenger experience with improved driving experiences due to better road conditions and reduced tire pressure issues caused by poorly designed wheels that cause excessive bouncing between cars). However, current testing techniques such as static strain tests may not accurately represent these physical features like those related to the behavioral responses from suspended systems.
