Research Engagements
Smart Optical Sensor
Kingston University
Exciting research project for a Degree in Physics, working alongside Texas Instruments developing 'Smart Optical Sensing Technologies.
The final product a unique large area photodiode coupled with digital signal processing and a serial bus integrated into a single DIL packaged device. Photometrics at its simplest, available commercially, the first in a range of optical telemetry by Texas Instruments for use in aeronautics, automotive etc.
Altimeter
Brunel University & MOD
Exciting project developing old concepts with new technologies, providing accurate, robust and reliable systems.
With a 'Smart Sensor' architecture, developed using 'epitaxial crystal' growth in a matrix formation, the optical sensor is functions with no moving parts and impervious to interference.
The bespoke integrated DSP configured to convert the sensor telemetry into data streams to be linked or integrated into flight or aircraft control systems.

NIR Spectroscopy (Foods)
Brunel University
Masters Degree research commissioned by Brunel University for the National Food Research Centre in India, and McDougalls flour UK, patented for in-line monitoring of food products using 'non-contact' methods.
Using 'Near-Infrared Absorption Spectroscopy' together with bespoke analog signal processing electronics, to determine chemical make-up, contaminant signatures and moisture content, all without laboratory intervention.
Incubator Gas Flow
Brunel University & Phillps
A significant development in the the area of healthcare, and used primarily in baby incubators to measure gas volumetrics in infants without constriction.
The development, more an application of technology, than a breakthrough of science principle, was a short but critical development.
Cleverly using a laser and precision sensor arrays, gas flow could be monitored accurately with relative ease, through measurement of the deviation of the laser.

Aero Jet Blades
Warwick University
Funded by Rolls Royce Aero-Engines an exciting team development with Warwick and Brunel Universities.
With YAG laser systems, alongside high speed cameras and super computers developed to track teflon fragments across a single jet-engine blade in a airstream traveling at the speed of sound.
Critical information of airflow dynamics around the 'high compression' turbo fan blade, provides data used for geometry and performance optimisation.
Material Stress Fatigue
Brunel University & Rover Group
A support role with a fellow researcher, into the study to detect, fatigue and catastrophic cracks in pressings, and tool wear in machining operations.
in a series of laboratory generated boundary events the characteristic signature of fatigue, cracks and dull tooling could be defined and isolated.
The sensor system industrialised using an ultrasonic 'Micro-Acoustics' array with a bespoke DSP, now used throughout industry for safety and quality control.
