Electrical Engineering/Expert Profile
Expertise
I have been an electronics engineer for 25 years. I can answer questions on analog and digital circuits and my specialty is sensors.
Experience in the area
I am the inventor on 23 US patents, and also some foreign ones. Developed sensors for over 25 years. Licensed private pilot (airplane and rotorcraft), have HAM radio license. I'm not an expert in computer networking.
What do you still hope to achieve/learn in this field?
I would like to pass on some information to help others.
