FWIW...someone recently PM me for clarification regarding my prior post...

I really have no idea where they take it all....however, it's explicit of what is what and, what does what....plug and play circuitry wise. e.g If they need DSP device....they call it up...if they don't, then they don't...mix and match devices, ...etc.

RE: new "terms"
IMO, what we have for the "terms" added to claims 1 and 19...an emphasis for interpretation of "power source coupled to control circuitry for supplying electrical power to device".

RE:new "claims"
IMO, what we have for new claims 23 -27 "As defined in claim 1".....and 28-32 "as defined in claim 19".. are details and additional device considerations that exemplify exactly what "device" means in... "power source coupled to control circuitry for supplying electrical power to "device"".

I do not know what else to tell you, other than it looks good, however, I have no idea where it all goes.
