AI Technical Summary

Benefits of technology

This patented system uses an on line testing technique called Near InfraRed Spectroscopy (NIR) Analysis Technology for detecting crop quality factors like moisture content or nutrients levels during harvesting processes. By utilizing this approach, complex procedures can be reduced while still achieving accurate results. Additionally, NIR analyzers provide precise data about crops' health status without requiring humans manually inputting them into specific locations within their environment. Overall, these technical benefits make farming more efficient and cost-effective than traditional techniques such as visual inspections.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the accuracy and efficiency of measuring grainy qualities (such as water or prote) from within an enclosed space called graininess measurement instrument(s). Current methods involve expensive and complicated procedures that take several hours to complete making it challenges to achieve high levels of precision during production operations.
