A light modulator configured to modulate at least two channels of an image to be projected and a lighting system configured to illuminate portions of the modulator corresponding to each channel with light having properties consistent with the channel. Further, the withstand voltage can be adjusted by changing the length of the field oxide film. While in the slot seizing state, the SU layer 3 interface state machine awaits confirmation of traffic channel establishment. A recess is formed between the column members which is configured to receive an article in nested relationship within the recess. The switching control is further coupled to switch the power switch to regulate the output of the power converter in response to the power limit signal.
