An intelligent electronic device having a terminal assembly for coupling the IED, e. The front surface has a central zone which has two different cylindrical curvatures which generate first and second central-zone refractive powers differing by an astigmatic factor. While the duplexing switching operation is being performed, the RTOS and a PCI controlling unit dump a memory of an active board to a standby board, thereby synchronizing a memory between the active board and the standby board. The method further includes stripping the stress liner from the gate structure and performing an activation anneal at high temperature on device. Harmonics that normally would be aliased before a transposition process are removed by a discrete time low pass filter at the same time that the tabulated waveform is reconstruction and resampling.
