These pages highlight a few of the projects I have been instrumental in and go into more depth on their interesting features than is possible in the resumé. However as I cannot cover them all, do have a look at the resumé and if there is anything in there of interest then contact me and I will go into more detail for you. Also here are links to the patents of which I am the inventor. These are from Espacenet interface to the published patent application databases of the UK Patent Office and others.
