AI Technical Summary

Benefits of technology

In this patented technology, there are two technical benefits that help improve the efficiency and safety of excavation machines during operations at various locations within their environment. Firstly, they use multiple sensors with different axes (moments) to monitor its health condition accurately without interrupting normal functioning. Secondly, these devices have a strong network connection making them suitable for long distance communications between remote points over wired networks like telecommunications lines. These features make extraction from difficult terrain faster than traditional methods while also ensuring safer operating conditions by reducing downtdown rates and improving maintenance costs associated with machine failure.

Problems solved by technology

This patented describes how complicated machines like roadsheets can be affected by external forces or environmental conditions causing them to break down overtime. These issues make accurate detection challenges even with advanced systems like Artificial Intelligence (AI) software tools trained against data from past experiences. However, this problem needs further investigation into its causes before making any significant changes during operation.
