SofPulse and ActiPatch both use 27.12 MHz -- Biotech_Traderz has a compelling case that Mayer is going with SofPulse instead of ActiPatch. We'll see, someday, hopefully.
Mayer stripped all the good stuff from his website. It's a bunch of AI hype and "404 Not Founds" now. I think Mayer would be smart to license the ActiPatch, but there's no way of knowing what he plans to do.
