Temperature control system using heart rate variability for hvac control
A recently granted patent (Publication Number: US11957489B2) discloses a temperature control system that integrates heart rate variability (HRV) data to regulate the heating, ventilation, and air conditioning (HVAC) system in an environment. The system includes sensors for generating an electrocardiogram (ECG) signal for occupants and environmental data such as temperature, air velocity, and humidity. The HRV controller processes the ECG signal to identify inter-beat intervals and adjusts the HVAC system based on these intervals and environmental data. The system can increase heating or cooling based on predefined thresholds of inter-beat intervals, ensuring occupant comfort.
Furthermore, the patent describes methods for controlling temperature using HRV parameters and a comfort classification model. By generating N HRV parameters and utilizing a multidimensional HRV parameter space, the system can determine the comfort level of occupants in the environment. The comfort classification model defines comfort and discomfort regions based on HRV parameters, allowing the HVAC system to adjust temperature settings accordingly. Additionally, the system can be integrated into vehicles with a telematics system to transmit HRV data and receive updated comfort classification models. The methods also include retraining the comfort classification model in response to manual setpoint changes to the HVAC system, ensuring optimal comfort for occupants based on HRV data and environmental factors.
