Abstract: Disclosed are methods for designing and employing a portable device for effecting a desired environment proximate to the device (including carrying out such methods under business arrangements encompassing two or more business entities). The effected environment includes, in part, temporary increases in the amount of water vapor as the device emits water vapor over some time duration, typically from about 1 or 2 minutes or so to about 15 to 30 minutes or so. Heat from a chemical heating engine is employed to drive off the water vapor. The device may also emit one or more ingredients adapted to be detected by olfaction. The device may be used to help address symptoms of various ailments, e.g., cold, flu, allergies, sinusitis, and the like. Also, the device may be employed to help promote a desired emotive state for the user of the device. The device promotes one or more desired states through auditory, tactile, visual, and/or olfactory signals.
