It would be really interesting to see a demo of Synap from Doctor Nunally similar to the Nunchi demonstration.  Its possible they are trying to incorporate this technology into the water sensing device to cover the practicing entity qualification on this patent also.    To be a practicing entity does one only need to draw up and design the product, or does one need to build a prototype, or maybe one needs to go into production?   Its fun to watch how this all plays out.
