Abstract
A method of alternatingly emitting two or more volatile materials comprises the steps of activating a first heater and emitting a first volatile material for a first period of time by emitting the first volatile material at a first primary evaporation rate and emitting the first volatile material at a first secondary evaporation rate after evaporation of the first volatile material at the first primary evaporation rate. The method further includes the steps of deactivating the first heater, activating a second heater, and emitting a second volatile material for a second period of time by emitting the second volatile material at a second primary evaporation rate and emitting the second volatile material at a second secondary evaporation rate after evaporation of the second volatile material at the second primary evaporation rate. The first and second secondary evaporation rates are less than the first and second primary evaporation rates.
