Title: Christopher Mark Hardingham: Innovator in Engine Technology and Solar Cell Manufacturing

Introduction

Christopher Mark Hardingham is a notable inventor based in Danbury, GB. He has made significant contributions to the fields of engine technology and solar cell manufacturing, holding two patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of Hardingham's latest patents is focused on Stirling engine instability detection and prevention. This invention includes a reciprocating piston that drives an alternator to provide electrical output. The current signal is measured by a current monitor, and a fast Fourier Transform (FFT) value is produced. The FFT of the current signal has been found to be directly related to the stability of operation of the Stirling engine. As harmonic peaks in the FFT increase, it indicates that the stroke length of the piston is approaching or exceeding a safe maximum. Corrective actions, such as reducing heat to the Stirling engine, can be taken as a result. Additionally, a variety of stroke length detectors are disclosed for use in combination with or separately from the FFT analysis of the current signal. Optical and mechanical switches, as well as analogue sensors, are also included, along with an accelerometer mounted on the casing of the Stirling engine.

Another significant patent by Hardingham is a manufacturing method for solar cell arrangements. In this method, a p-n junction is formed in semiconductor material, which is then separated to create a main body and an off-cut. The off-cut is connected in reverse parallel across the main body to act as a protection diode for a solar cell that comprises the main body. The off-cut protection diode may be placed adjacent to the main body or alternatively mounted on the front or rear of the solar cell.
