Aerosol Device Wireless Security via Power Pattern Verification

The patent introduces power pattern verification as an intermediary mechanism between the wireless communication units of the main body and cartridge. Before establishing a wireless connection, the controller verifies that the power supplied to the cartridge matches a preset power pattern. This intermediary check prevents unintended connections by ensuring that only authorized cartridges (receiving correct power patterns) can form wireless connections with the main body.

The patent performs power pattern verification as a preliminary action before enabling wireless communication. The controller checks whether the power supplied to the cartridge matches the expected pattern before the wireless communication unit establishes a connection. This preliminary verification ensures that communication functionality is only activated when the cartridge is properly authorized, thereby preventing security issues while maintaining communication capabilities.

The patent makes the battery serve multiple functions: it provides power for heating the aerosol generating material and simultaneously serves as a power source for verification-based wireless communication. By making the battery universal, the system avoids adding separate verification hardware, thereby improving connection security without significantly increasing device complexity.

The system uses its own existing power supply infrastructure (the battery and controller) to perform verification-based communication authorization. Rather than introducing external verification devices, the controller leverages the existing power management circuitry to determine whether to enable wireless connections based on power consumption patterns. This self-service approach enhances security while minimizing additional complexity.
