Title: Innovations by Keith Johnson

Introduction

Keith Johnson is an accomplished inventor based in El Segundo, California. He has made significant contributions to the field of sheet feeding technology, holding a total of 2 patents. His work primarily focuses on improving the efficiency and reliability of multi-tray sheet feeders.

Latest Patents

Johnson's latest patents include a "Misfeed detector for multi tray sheet feeders" and a "Misfeed detector for multi-tray and intermediate tray sheet feeders." The first invention relates to an apparatus that detects sheet misfeeds from a multi-tray sheet feeder. It utilizes a common sensor to detect the thickness of the first sheet fed from each tray, storing this value in memory. Subsequent sheets are compared against this stored value to determine if a misfeed has occurred. If the thickness exceeds the stored value, the system shuts down, allowing the operator to address the issue. The second patent enhances this concept by incorporating an intermediate tray, where the thickness of sheets is also monitored as they exit. This dual-sensor approach further ensures that only one sheet passes through at a time, improving operational reliability.
