User Feedback System for Adaptive Aerosol Delivery

The patent implements a feedback mechanism where sensors continuously monitor user state parameters (such as heart rate, breathing rate, temperature) and this information is fed back to a controller that adjusts the delivery device parameters accordingly. This closed-loop feedback system enables the device to adapt dynamically to changing user states while maintaining a relatively simple overall structure by using standard sensor and control components.

The patent employs a multi-functional controller that handles multiple tasks including sensor data processing, user state estimation, delivery parameter adjustment, and communication with external devices. By consolidating these functions into a single integrated control unit rather than separate dedicated circuits for each function, the system achieves high reliability while maintaining ease of manufacture through reduced component count and simplified assembly processes.

The patent implements periodic sampling of user state parameters rather than continuous monitoring at maximum frequency. The controller adjusts the sampling rate dynamically based on the current state - using higher rates when rapid changes are detected and lower rates during stable periods. This periodic action with variable frequency maintains measurement precision for accurate delivery control while significantly reducing average power consumption compared to continuous high-frequency monitoring.
