-“external functional circuit”
-“externally generated”
-“second externally generated electrical signal”

Judge Andrews also construed the following terms specifically for Power Management Solutions, LLC v. Advanced Micro Devices, Inc., C.A. No. 12-426-RGA-CJB:
-“first electrical signals”
-“electrical power is controllably passed from an external power supply through the power gating means to the internal functional circuit”
-“one or more first electrical signals are controllably passed between an external functional circuit and the internal functional circuit via the switching means”
