I feel the need to throw this idea out. It has been popping into my head now and again but I have had no time to pursue it in depth, at the moment, or in the near future.
It concerns TPU frequency control. It may turn out to be nothing. Or not. Here we go.
Mark Tilden's Micro-core "nervous-net" design for BEAM robotics. (More popular about a decade ago.) Google it.
I recall that it can be wired to change it's timing, and even it's gate, in response to feedback caused by it's output. This is the key that makes the connection to a TPU frequency control design in my mind.
Steve Mark said something to the effect that we need to tune slightly off the crest of the feedback or we cause a thermal anomaly.
If this works then I hereby declare it in the name of open source from this day forward. Tilden's patent concerned walking gates of robots, not coil resonance control. If his circuit is modified for this reason then it becomes a new device in it's own right, right?
Have fun with it! :)

I used a nervous-net to send a pulse through a hooped bifilar coil. A sister coil looked like it sensed something. Oh, and I buried Spherenot.

Wow that board looks busy!
Nice scope shot.

What do you think of this unit for a TPU?
