State information is synchronized between a plurality of routing engines in a multi-chassis router according to a synchronization gradient. In one example, an air inlet throttle is at least partially closed in response to a change in engine torque request. The slide units slide within the tracks and enable container roll in, roll out platforms and 1077 flatracks to be slidably moved into and out from the cargo area. The widths of ribbons and gaps within a particular pixel affect the polarization dependent loss of a pixel, and affect the first order diffraction angle. All colors of ink can then be placed in a single layer before the cure reflector fully cures the UV inks by reflecting sufficient UV radiation onto the single layer of UV ink. The sigma-delta modulation unit receives the oversampled signal and performs sigma-delta modulation to generate a modulated signal.
