1. An apparatus for dispensing active materials, comprising:
- a housing; and
control circuitry disposed within the housing that implements programming for a mode of operation in which during a first sustained period of time a first active material is emitted in the form of discrete bursts each followed by a first dwell period, during a second sustained period of time the first active material is emitted in the form of discrete bursts each followed by a second dwell period and a second active material is emitted in the form of discrete bursts each followed by a third dwell period, wherein during the second sustained period of time the discrete bursts of the first and second active materials are emitted such that when a discrete burst of one of the first and second active materials is emitted, a discrete burst of the other of the first and second active materials is initiated before the discrete burst of the one of the first and second active materials is terminated, and during a third sustained period of time the second active material is emitted in the form of discrete bursts each followed by a fourth dwell period.

Abstract
An apparatus for dispensing active materials comprises a housing and control circuitry disposed within the housing. The control circuitry implements programming for a mode of operation in which during a first period of time a first active material is emitted, during a second period of time the first active material and a second active material are emitted, and during a third period of time the second active material is emitted, wherein during the second period of time, the first and second fragrances are alternated.

8. A method of dispensing active materials, the method comprising the steps of:
-
emitting a first active material in the form of discrete bursts each followed by a first dwell period for a first sustained period of time; emitting the first active material in the form of discrete bursts each followed by a second dwell period and a second active material in the form of discrete bursts each followed by a third dwell period for a second sustained period of time, wherein during the second sustained period of time the discrete bursts of the first and second active materials are emitted such that when a discrete burst of one of the first and second active materials is emitted, a discrete burst of the other of the first and second active materials is initiated before the discrete burst of the one of the first and second active materials is terminated; and emitting the second active material in the form of discrete bursts each followed by a fourth dwell period for a third sustained period of time. - View Dependent Claims (9, 10, 11)

12. A method of dispensing active materials, the method comprising the steps of:
-
periodically emitting discrete bursts of a first active material for a first sustained period of time; periodically emitting discrete bursts of the first active material and a second active material for a second sustained period of time; and periodically emitting discrete bursts of the second active material for a third sustained period of time; wherein during the second sustained period of time, the discrete bursts of the first and second active materials are alternately emitted such that when a burst of one of the active materials is emitted, a burst of the other of the active materials is initiated before the burst of the one of the active materials is terminated. - View Dependent Claims (13, 14, 15, 16, 17)
