<i>there are two nontrivial challenges to producing a viable implementation: 1) intellectual property</i><p>Hey, wait just a moment! Copyright and patents are supposed To promote the Progress of Science and Useful Arts, not hinder them by posing challenges.
That's clever. All that complexity leads to lower power consumption, because the device is dynamically driven at its resonant frequency. You could drive it at a fixed frequency, calibrated once at the factory, and avoid patent problems.
