Spaced-apart spacer ribs are mounted on the outer flat sides of the extruded profiles. The heat spreader includes a post and a base. The licensed in-vitro diagnostic test may comprise a licensed biomarker test, for example one obtained by DNA or RNA sequencing, and the method may further comprise: performing the licensed biomarker test using a genome sequencer, wherein the performing of the licensed biomarker test and the computing of license compensation are both performed at a single medical facility. At least the carrier grains are sealed in a space formed in the developing device until the developing device starts being used while the toner grains are introduced in the developing device at the start of use. The controller is configured to receive a command to write a unit of primary data to a first storage location.
