Title: Marjatta Piironen: Innovator in Process Monitoring and Starch Determination

Introduction

Marjatta Piironen is a notable inventor based in Espoo, Finland. With an impressive portfolio of 15 patents, Piironen has made significant contributions to the fields of process monitoring and starch determination.

Latest Patents

Among her latest inventions is a method and system for monitoring a process. This innovative approach allows for the monitoring of a process through the utilization of explanation values. A machine learning (ML) model is created using measurements from the process as inputs. The model outputs are then generated, and the inputs are classified into groups. Explanation values, indicating the contribution of each input to the model outputs, are calculated. The sums of these explanation values for each group are monitored, providing insights into their status.

Another notable patent focuses on the determination of starch in a sample. In this method, a liquid sample—such as pulp suspension or filtrate from a paper, board, or tissue process—is analyzed. An iodine solution is added, and the light absorbance or transmittance is measured at wavelengths longer than about 650 nm. The absorbance or transmittance is then converted into starch concentration using predefined correlations, enhancing measurement accuracy.
