Title: Innovations by David L St Pierre

Introduction

David L St Pierre is an accomplished inventor based in Mason, MI (US). He has made significant contributions to the field of engine technology, holding 2 patents that showcase his innovative approach to solving complex engineering challenges.

Latest Patents

One of his latest patents is titled "Method of crank signal disturbance compensation." This invention provides an engine system that compensates for disturbances in a crankshaft signal. The system includes an error module that computes an error between an ideal period and an actual period of a crankshaft signal. Additionally, a correction factor module determines a correction factor based on the error, while a compensation module applies the correction factor to the actual period of the crankshaft signal.

Another notable patent is the "Misfire detection apparatus for internal combustion engine based on piston speed." This invention includes a method of detecting a misfire in an internal combustion engine. The method involves detecting a first engine speed at a first crankshaft position that corresponds to about a top dead center compression position of a first piston within a first cylinder. It also detects a second engine speed at a second crankshaft position that corresponds to a position subsequent to the top dead center compression position. The method determines whether a misfire occurred in the first cylinder based on the first and second engine speeds, providing an improved signal-to-noise ratio for engine misfire detection.
