"investing in a company is not play and should have a much higher expectation of success."

You would think.....however, "control cirtury" is giving us a problem....

I can't imagine coming all this way to get stuck on....

"a power source coupled to > the control circuitry> for supplying electrical power to the device"

Note that is reads "power source", where the concepts of the patent employ multiple power source from multiple "power supply" issues.

For that particular phrase regarding "power source" the "control circuitry" regulates, imparts, supplies(whatever) the power "to the device" issues.

Your investment...has come down to a play on words and differentiating status quo power supply methods from e.Digitals power source methods.

None of the considered prior art establishes any similarity of words used..especially "control circuitry"...because, .... there is a reason they are composed as they are.
