Having worked from 1978-2001 as a professional engineer and inventor, I am named as inventor on 39 patents, mostly for tools and medical devices. Many of these have been successfully commercialised.
Although I no longer invent professionally, I now invent simpler devices to address my “unmet needs”. Where these may be useful to others, I make them available under a Creative Commons BY-NC-SA license. This means that you may use or modify the design for non-commercial purposes, so long as you acknowledge me as the original creator and any derivatives are also shared under the same license terms.
If you would like to make use of the designs for commercial purposes, please contact me.
