AI Technical Summary

Benefits of technology

This technology helps identify variations that may affect cigarettting quality during manufacturing by analyzing its variation with regards to factors like processing conditions or environmental variables such as temperature. By comparing this data against predetermined thresholds, it becomes possible to detect any deviating results from these processes. It also allows users to easily see if there's an issue at one machine or location compared to another similar machine/site. Overall, this innovative approach provides technical benefits over existing methods used alone.

Problems solved by technology

This patents discuss various methods that can help improve the accuracy and consistency with regards to analyzing mass amounts of quality material collected over time on an industrial scale (IoC). These technical problem addressed include variations caused by factors like variation in manufacturing processes and equipment, changes made after they were produced, and external influences affecting the final product's appearance. Statistics tools cannot provide accurate results because only small numbers of representative measurements may represent important aspects of the overall performance of the cigarettage machine.
