Classification: CPC A  B  F | IPC A  B  F

Claim 4:
5. A temperature control system, comprising:
a heating, ventilation and air conditioning (HVAC) system configured to control temperature in an environment;
a sensor configured to generate an electrocardiogram (ECG) signal for an occupant of the environment;
an environmental sensor configured to sense environmental data selected from a group consisting of the environmental temperature, an ambient temperature, air velocity, sun load and humidity; and
a heart rate variability (HRV) controller configured to:
receive the ECG signal;
identify inter-beat intervals based on the ECG signal; and
control the HVAC system based on the inter-beat intervals and the environmental data, wherein the HRV controller is further configured to:
generate N HRV parameters based on the inter-beat intervals, where N is an integer greater than one; and
use a comfort classification model defined in a N-dimensional HRV parameter space.
