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.

We claim: 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
We claim: 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. 2. The apparatus of claim 1, in combination with first and second bottles having first and second active materials therein and first and second wicks in contact with the first and second active materials, respectively, and extending outside of the respective bottles. 3. The apparatus of claim 2, further including first and second piezoelectric devices that are operated by the control circuitry, wherein the first and second piezoelectric elements are in contact with the first and second wicks, respectively, to dispense the first and second fragrances therefrom. 4. The apparatus of claim 1, wherein the control circuitry implements programming for a second mode of operation in which only the first active material is emitted. 5. The apparatus of claim 4, wherein the control circuitry implements programming for a third mode of operation in which only the second active material is emitted. 6. The apparatus of claim 5, wherein a switch is disposed on the housing to allow selection of the first-named, second, or third modes of operation. 7. The apparatus of claim 1, wherein the first and third periods of time have durations that are the same. 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. 9. The method of claim 8, further including the step of emitting the first active material in the form of discrete bursts each followed by a fifth dwell period and the second active material in the form of discrete bursts each followed by a sixth dwell period for a fourth sustained period of time, wherein during the fourth 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. 10. The method of claim 9, wherein the second sustained period of time follows the first sustained period of time, the third sustained period of time follows the second sustained period of time, and the fourth sustained period of time follows the third sustained period of time. 11. The method of claim 10, wherein the method steps performed during the first, second, third, and fourth sustained periods of time are repeated for a fifth sustained period of time. 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. 13. The method of claim 12, further including the step of periodically emitting discrete bursts of both the first and second active materials for a fourth sustained period of time. 14. The method of claim 13, wherein the discrete bursts of the first and second active materials are alternately emitted during the fourth sustained period of time 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. 15. The method of claim 12, wherein a sequence is repeated during the second sustained period of time and the sequence includes bursting the first active material, initiating a burst of the second active material before the burst of the first active material is finished, thereby creating an overlap period, causing delivery of the first active material to enter a dwell period before the second active material is finished bursting, thereafter causing the second active material to enter a dwell period, bursting the second active material, initiating a burst of the first active material before the burst of the second active material is concluded, causing the second active material to enter a dwell period before the burst of the first active material is terminated, and thereafter causing the first active material to enter a dwell period. 16. The method of claim 15, wherein a sequence is repeated during the fourth sustained period of time and the sequence includes bursting the second active material, initiating a burst of the first active material before the burst of the second active material is finished, thereby creating an overlap period, causing the second active material to enter a dwell period before the first active material is finished bursting, causing delivery of the first active material to enter a dwell period, bursting the first active material, initiating a burst of the second active material before the burst of the first active material is concluded, causing the first active material to enter a dwell period before the burst of the second active material is terminated, and thereafter causing the second active material to enter a dwell period. 17. The method of claim 12, wherein the second sustained period of time follows the first sustained period of time and the third sustained period of time follows the first sustained period of time.
