Patent ID: 8897629

Claim:
A scent delivery apparatus configured to emit one or more airborne scents in an environment of a user, the apparatus comprising: a scent provisioning apparatus comprising: a reservoir configured to contain a substance, the substance being configured to release an airborne scent responsive to being heated; a capillary disposed at least partially within reservoir, the capillary comprising a tube with a bore configured to draw the substance through a portion of the capillary by way of capillary action; and a filament comprising a strand of a high-temperature compatible conductive material, the filament including two end portions having a coating thereon, the coating including a material configured to reduce a resistive heating of the two end portions, at least a non-coated portion of the filament being disposed at least partially within the capillary, the filament being configured to heat the substance within the capillary by way of resistive heating provided by passing a current through the filament, wherein the non-coated portion of the filament emits a greater level of heat than the coated two end portions under the same amount of current, such that the non-coated portion facilitates the delivery of the greater level of heat to one or more specific regions within the capillary where the non-coated portion is at least partially disposed; wherein the scent delivery apparatus is configured to receive information associated with a level of current to be passed through the filament to control a temperature level of the filament, an intensity of the airborne scent released responsive to heating the substance being controlled based on the temperature level of the filament.
