A rotating masking disc aligns with segmented flavor sections to mix precursor composition with specific flavorants in an aerosol cartridge.
Asymmetric fiber cutting disrupts longitudinal alignment to prevent non-uniform heat generation in sheet-shaped heaters.
Segmented bifilar heating conductors cancel electromagnetic emissions while accommodating thermal expansion through flexible thread mounting.
Varying helix pitch in the heating wire creates higher power in cold zones and lower power under the bonnet to prevent overheating.
