Charge Coupled Devices

During my time at Bell Laboratories, I worked for Nobel laureate George Smith, supervising a group working on Charge Coupled Devices, particularly for data storage and signal processing applications.  Within the same department, there was another group dedicated to imaging.  Now everyone knows that imaging is where the CCD has excelled, and in some work that was never published, I showed that there was no economic case for CCD's in the memory hierarchy.  Years later, when I joined Fairchild, we had to go through that same argument again.

The principal evidence of my CCD activity is now a handful of papers and patents.  The CCD papers are here,  and the CCD patents are with all the other patents.
