METHOD OF ALTERNATINGLY EMITTING TWO OR MORE VOLATILE MATERIALS
First Claim
1. A method of alternatingly emitting two or more volatile materials, the method including the steps of:
- (a) activating a first heater to emit a first volatile material;
(b) emitting the first volatile material for a first period of time including the steps of;
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;
wherein the first secondary evaporation rate is less than the first primary evaporation rate;
(c) deactivating the first heater;
(d) activating a second heater to emit a second volatile material;
(e) emitting the second volatile material for a second period of time including the steps of;
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;
wherein the second secondary evaporation rate is less than the second primary evaporation rate;
(f) deactivating the second heater; and
repeating the steps of (a) through (f).

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.

8. A method of alternatingly emitting two or more volatile materials, the method including the steps of:
-
(a) activating a first heater to emit a first volatile material; (b) emitting the first volatile material for a first time period of time including the steps of; during a first portion of the first time period, emitting the first volatile material such that a first primary room concentration is achieved; and during a second portion of the first time period, emitting the first volatile material such that a first secondary room concentration is achieved; wherein the first secondary room concentration is less than the first primary room concentration and the first secondary room concentration occurs after the first primary room concentration; (c) deactivating the first heater; (d) activating a second heater to emit a second volatile material; and (e) emitting the second volatile material for a second time period of time including the steps of; during a first portion of the second time period, emitting the second volatile material such that a second primary room concentration is achieved; and during a second portion of the second time period, emitting the second volatile material such that a second secondary room concentration is achieved; wherein the second secondary room concentration is less than the second primary room concentration and the second secondary room concentration occurs after the second primary room concentration; (f) deactivating the second heater; and repeating the steps of (a) through (f). - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method of alternatingly emitting two or more volatile materials, the method including the steps of:
-
(a) activating a first heater to emit a first volatile material; (b) emitting the first volatile material for a first time period; (c) deactivating the first heater; (d) activating a second heater to emit a second volatile material, wherein the second heater is activated prior to deactivation of the first heater, at the same time as deactivation of the first heater, or after deactivation of the first heater; (e) emitting the second volatile material for a second time period; (f) deactivating the second heater; and repeating the steps of (a) through (f); wherein, prior to repeating step (a), a room concentration of the first volatile material is reduced to a level of less than or equal to about 0.4 milligrams per cubic meter and, prior to repeating step (d), a room concentration of the second volatile material is reduced to a level of less than or equal to about 0.4 milligrams per cubic meter. - View Dependent Claims (17, 18, 19)
