A method and apparatus for reformatting electronic documents is disclosed. Each of the planetary gear sets includes first, second and third members. The first dispersive optical element and the second dispersive optical element cooperate to disperse received EMR into a plurality of even frequency spaced EMR spectra. The first heat-dissipating fin has a first heat-dissipating portion, a first end and a second end. If the conveyor is moving but no items are on the belt, a reduced amount of lubricant is dispensed onto the conveyor system. The front shield may consist of at least a seed layer and a shielding layer with the shielding layer having an easy axis coercivity along a first direction of 4 Oe or more and a hard axis coercivity along a second direction of 0.
