Smoke constituent reduction is achieved by resolving from puff-to-puff analysis at which location along a tobacco rod production of a particular smoke constituent is maximized, and locally applying an attenuator at said resolved location to reduce production of the constituent. An anatomical imaging system comprising: a CT machine; and a transport mechanism mounted to the base of the CT machine, wherein the transport mechanism comprises: a gross movement mechanism for transporting the CT machine relatively quickly across room distances; and a fine movement mechanism for moving the CT machine precisely, relative to the patient, during scanning. The method continues by generating a transmit blocking indication based on the first protocol probable active time period and the first protocol probable inactive time period. The subject methods employ an algorithm that employs a different dispersity measure depending on whether the signal features are weaker or stronger. The system is formed with a coupling module for the laser beam, at least one beam guiding module for the laser beam and a processing module, which can be connected to one another. The decoder examines the prefix bit of each code word as it is received to determine if the code word stores a symbol in plain or in index.
