Title: The Innovations of Mark A. Laubenstein

Introduction

Mark A. Laubenstein is a notable inventor based in Windfall, Indiana, known for his contributions to the field of ignition systems. With a total of two patents to his name, Laubenstein has made significant advancements in the technology surrounding internal combustion engines.

Latest Patents

Laubenstein's latest patents include a method of indicating combustion in an internal combustion engine. This innovation provides absolute engine position sensing by monitoring the temporal relationship of energization of multiple spark plugs sharing a common source of drive energy in a direct ignition application. The spark plugs are connected across the source with opposing electrical polarity, and the relative time of discharge across the plugs is compared by sensing the time and polarity of high-speed transient activity in proximity to the source.

Another significant patent is the method of suppressing ringing in an ignition circuit. This invention involves an inductive ignition circuit, comprising a secondary winding across a spark plug and a primary winding in series with a lossy transistor switch and a power source. The circuit is subject to ringing at the start of the dwell period, which can cause premature combustion. Laubenstein's method suppresses ringing by utilizing a short switch turn-on pulse followed by a short delay prior to the main dwell period, allowing for a buildup of primary current and circuit energy.
