Title: Innovations by James Alan Felsheim

Introduction

James Alan Felsheim is an accomplished inventor based in Grants Pass, Oregon. He has made significant contributions to the field of wood drying technology, holding a total of 2 patents. His work focuses on improving the efficiency and effectiveness of kiln operations, which are crucial in the lumber industry.

Latest Patents

Felsheim's latest patents include a "Method for Monitoring Wood-Drying Kiln State" and a "Kiln Controller." The method for monitoring kiln state utilizes a known good set of moisture content data for wood dried in a kiln under set conditions. It estimates parameters for a Lognormal distribution that approximates the moisture content data for those conditions. This innovative method creates control charts to monitor these parameters and takes data from subsequent kiln charges to represent it on the control charts. This representation helps determine if the kiln is operating under out-of-control conditions.

The kiln controller patent describes a system that controls the drying of lumber in a kiln by executing a drying schedule. It adjusts the drying schedule in response to actual measured conditions in the kiln. A computer within the controller manages heating coils, spray nozzles, and vents to achieve the prescribed conditions. The computer first brings the kiln temperature up to a desired initial temperature and then concurrently executes the drying schedule while monitoring temperature, vent load, and spray nozzle activity. It automatically adjusts the duration of the current step in the drying schedule to optimize the drying process.
