RE: importance of 774
108 conditions " ; and a power source coupled to the control circuitry for supplying electrical power to the device."

The 774 re-exam rectifies the arguments of claims construction regarding the control circuitry issues…of what and where it controls….any type device, on, or off a PCB.
