Yang Zhao, Neal Patwari and I just got done testing a totally new system for radio tomographic imaging. It uses new radio node hardware that we manufactured ourselves, a new imaging algorithm, and new "teepee" stands for quick and easy demos. The new images are bright and clear, the hardware/firmware is fast/stable, and the new stands set up in a fraction of the time. We're pretty psyched because every element of the system has been improved.
By the way, I am using Google+ more and more these days. If you're interested in following me, here's the link: https://plus.google.com/101773630805931921626/posts
