1. A method of flattening a perfume-release profile from a heated-wick perfume composition-dispensing device comprising:
- a) applying heat to the wick to achieve a wick temperature sufficient to increase the rate of volatilization of at least one component of the perfume composition, wherein the increased volatilization occurs for a period of from 17 minutes to about 72 minutes;
b) reducing the heat to achieve a wick temperature sufficient to decrease the rate of volatilization of the at least one component of the perfume composition;
c) maintaining the reduced heat for a time sufficient to allow for back-flow of at least one component of the perfume composition, the time being 17 minutes to 72 minutes; and
repeating a).

Abstract
Systems, devices, methods, and compositions that improve the scent perception for a user. Improved scent perception is achieved by presenting alternating scents and by varying levels of output of scents, as well as by minimizing device clogging, thereby improving evaporation profiles.

2. A method of flattening a perfume-release profile from a heated-wick perfume composition-dispensing device comprising two or more perfume modules comprising at least a first and second reservoir containing a perfume composition, and at least a first and second wick in fluid communication with the perfume composition, comprising:
-
a1) applying heat to the first wick to achieve a wick temperature sufficient to increase the rate of volatilization of at least one component of the perfume composition; b1) reducing the heat applied to the first wick to achieve a wick temperature sufficient to decrease the rate of volatilization of the at least one component of the perfume composition; c1) maintaining the reduced heat for a time sufficient to allow for back-flow of at least one component of the perfume composition, the time being about 20 minutes to about 24 hours; a2) automatically applying heat to the second wick to increase volatilization of at least one component of the second perfume composition; b2) reducing the heat applied to the second wick to a temperature sufficient to decrease volatilization of the at least one component of the second perfume composition; c2) maintaining the reduced heat applied to the second wick for a time sufficient to allow for back-flow of at least one component of the second perfume composition the time being about 20 minutes to about 24 hours; repeating a1); and repeating a2); wherein the first and second wick have an average pore size of from 50-150 microns. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 12, 13, 14, 15, 16, 17, 18, 19)
