An apparatus and a method for processing excess transport streams in a broadcast receiver are provided. The control system includes a control handle bar with left and right hand grips, and first and second control roll bars located on either side of the lift platform’s central cowling. An upper surface of the first layer has a tiling arrangement of pyramidal or frustro-pyramidal protrusions of semiconductor material surrounded by a material of different refractive index which together comprise a photonic band structure. Adapting the refractory period may involve, for example, initiating a refractory period, terminating a refractory period, extending a refractory period or modifying one or more parameters of the refractory period.
