Spectroscopic Taggants in Aerosol Articles for Heating Protocol Control

The patent applies color changes by using taggants with distinct optical properties that reflect or absorb light at specific wavelengths. Authentic articles contain taggants with verified optical signatures, while counterfeit articles lack these specific optical characteristics. The detector uses optical radiation to illuminate the article and measures the reflected or absorbed light to identify the unique optical signature of authentic taggants, enabling reliable authentication without complex mechanical structures.

The patent replaces mechanical or chemical identification methods (such as printed ink codes that can be copied) with an optical detection system. Instead of using physical tags or printed information that can be replicated, the system uses optical radiation interaction with taggant materials to create a non-contact, non-intrusive authentication mechanism that is difficult to counterfeit.

The patent applies local quality by incorporating taggants with different optical properties into different types of smoking articles. Each article type contains taggants with specific optical signatures that are unique to that article type. The detector can identify the specific optical signature to determine the article type, enabling the system to adapt its operation to the specific article being used while maintaining the ability to distinguish between different authentic article types.

The patent uses parameter changes by varying the optical properties (wavelengths reflected or absorbed) of taggants across different article types. This allows the detector to distinguish between different article types based on their unique optical parameter signatures, enabling the system to recognize and adapt to multiple authentic article types without confusion.

The patent applies preliminary action by performing taggant verification before system activation. The detector illuminates the article with optical radiation and analyzes the reflected or absorbed light to verify the presence and authenticity of taggants before allowing the heating element to operate. This preliminary verification ensures that only authentic articles can be activated, preventing counterfeit article misuse while maintaining ease of operation for authentic articles.

The patent implements preliminary anti-action by preventing system activation when counterfeit articles are detected. The detector identifies the absence or incorrect optical signature of taggants and blocks the heating element from operating, thereby preemptively preventing the harmful effects of using counterfeit articles before they can occur.
