Abstract

In the area of automotive body electronics,"win- dow anti-pinch" regulations are becoming more and more important to our customers. Specifically, a competitive advantage can be gamed if one can pro- vide a system which detects window blockage and prevents the object from being caught in the win- dow. Current systems involve actually waiting for a pinch to occur and noting the increase in motor cur- rent, then backing off the window. Other systems use infrared sensors to detect an object blocking the window.
