A power control system and method controls power supplied from a power source to a resistive load, such as a LED illumination array, to prevent the load from exceeding a high temperature limit. An air and pressure tight container stowed within the aircraft has a doorway that is sealed to and about the hatch from within the aircraft. The ADC is configured to receive demodulated analog signals from the demodulator. The semiconductor wafer is then plasma etched through the gaps in the patterned mask to singulate the integrated circuits.
