Title: Arno Friedrich: Innovator in Actuator Technology
Introduction
Arno Friedrich is a notable inventor based in Wuppertal, Germany. He has made significant contributions to the field of actuator technology, holding a total of 12 patents. His work focuses on improving the functionality and reliability of actuators in various applications, particularly in internal combustion engines.
Latest Patents
Friedrich's latest patents include a method for determining defective actuators in an internal combustion engine. This innovative method detects faulty actuators by calculating a mean value of all actuators present on the cylinders. The measurement variable is influenced by at least one parameter, and a deviation is formed that remains constant across the entire parameter range. The method establishes limit values based on this deviation and the mean value. If any measurement variable exceeds these limit values, the actuator is identified as faulty or defective.
Another significant patent involves a method for controlling a piezoelectric actuator used to displace an element. This invention addresses the return stroke between the actuator and the element. The control voltage applied to the actuator is adjusted based on the size of the return stroke, ensuring precise displacement and compensation for any alterations in the return stroke.
