Show moreAn apparatus for generating odor upon electronic signal demand using a disk having an aroma-impregnated adsorbent and a substrate. The disk is inserted into a disk drive that receives signals from a user and/or a server computer. A controller within the disk drive supplies an electric, mechanical or thermal signal to the disk, resulting in the heating of the adsorbent. The controller may also activate a blower to distribute the scent produced by the heated adsorbent and to cool the adsorbent at the end of the scent distribution cycle.

Show moreAn apparatus for generating odor including a disk having a substrate with a dispersing material retaining at least one releasable aroma positioned with respect to the substrate. The dispersing material includes a structure, such as a plurality of openable pores, that is physically responsive to a stimulus such as heat or light. A device provides the stimulus to the dispersing material upon demand as a function of a signal, wherein the plurality of pores within the dispersing material are reversibly enlarged as a result of the stimulus.
