Thank you very much for the note; yes the patent process is step one. I built a timeline graphic that's in the linked site.

I was also thinking like industrial or medical applications, so that doors would be hands free. As a home device, I'd like to make a really simple version - think The Clapper for lights [1] - that could help elderly or mobility impaired people in their own homes. I've had a great introduction with a Patent Attorney who will assist crafting a broad, useful patent application, which is exiting in its own right!
