Introduction

Philip Extance is a notable inventor based in Solihull, GB. He has made significant contributions to the field of engineering, particularly in the area of combustion monitoring and position encoding. With a total of 2 patents to his name, Extance's work reflects a commitment to advancing technology in practical applications.

Latest Patents

One of Extance's latest patents is focused on combustion monitoring. This invention outlines a method for monitoring combustion within a cylinder of a reciprocating piston internal combustion engine. It involves deriving first and second electrical signals that represent light intensity within the cylinder using optical transducers. These transducers observe the combustion event at closely adjacent locations, establishing a signal that represents the ratio of the two electrical signals. This ratio signal is crucial for obtaining a control parameter for an engine control system. The invention also includes apparatus for monitoring combustion in accordance with this method.

Another significant patent by Extance is an incremental position encoder that employs three or more colors. This device consists of a first member that moves with a second member, which is monitored for movement. It features a series of light transmissive or reflective elements of three distinct colors arranged in a repeating sequence. A light source directs light to these elements, and a color-sensitive light detector produces distinct outputs based on the color of the element transmitting or reflecting light at any given moment.
