Aerosol-generating article and electrically operated system incorporating a taggant

Abstract

The present invention relates to a method of controlling an aerosol-generating system, and the associated system. The system comprises: an aerosol-generating article; and an aerosol-generating device. The device having a detector capable of detecting the presence of the aerosol-generating article and distinguishing the aerosol-generating article from other articles configured for use with the aerosol-generating system, based on a spectroscopic signature of a taggant incorporated within a material of the aerosol-generating article. The method comprises the steps of: detecting the presence of an aerosol-generating article; determining whether the article comprises a taggant; comparing the spectroscopic signature of the detected taggant with a look-up table of taggant spectroscopic signatures corresponding to articles configured for use with the system; preventing activation of the device, including preventing the supply of power to the heating element, unless the detected taggant spectroscopic signature corresponds to an article configured for use with the system; and activating the device if the detected taggant spectroscopic signature corresponds to an article configured for use with the system.

Description

technical field [0001] The present invention relates to aerosol-generating articles incorporating markers for use in electrically-operated aerosol-generating devices as part of an electrically-operated aerosol-generating system. In particular, the aerosol-generating article may be a smoking article. Background technique [0002] Numerous documents such as US-A-5 060 671, US-A-5 388 594, US-A-5 505 214, WO-A-2004 / 043175, EP-A-1 618 803, EP A 1 736 065 and WO - A-2007 / 131449 discloses an electrically operated aerosol generating smoking system with many advantages. One advantage is that they significantly reduce sidestream smoke while allowing the smoker to selectively pause and resume smoking. [0003] Electrically heated smoking systems typically include a power source, such as a battery, connected to a heater to heat the aerosol-forming substrate to form an aerosol that is delivered to the smoker. In operation, these electrically heated smoking systems typically provide h...

AI Technical Summary

Problems solved by technology

The use of smoking articles with lit ends in electrically heated smoking systems can result in a poor smoking experience for the user and can also damage the system because, for example, the smoking article is not compatible with the system

Additionally, there may be many different smoking articles, each configured for use with the system, but each providing a different smoking experience for the user
