Vehicular heatstroke prevention device
First Claim
1. A vehicular heatstroke prevention system for use in a vehicle, the system comprising:
- a carbon dioxide sensor;
a temperature sensor;
a vehicle door sensor; and
a processor, wherein the processor is configured to;
detect if an engine of the vehicle is off and, via the vehicle door sensor, if all doors of the vehicle are closed,if the doors are closed, monitor changes in carbon dioxide (CO2) levels in the vehicle via the CO2 sensor to thereby detect the presence of a breathing person or animal in the vehicle;
after the presence of a breathing person or animal in the vehicle has been detected by the CO2 sensor, monitor a temperature (T) inside the vehicle via the temperature sensor; and
if T reaches or exceeds a preset value (T1), activate the vehicle'"'"'s air conditioning unit and/or lower at least one of the vehicle'"'"'s windows.

Abstract
A passive vehicular heatstroke prevention system monitors carbon dioxide (CO2) and infrared (IR) energy levels to determine whether a child is present inside a closed vehicle, and, if so, monitors the temperature in the vehicle and, if the temperature in the vehicle exceeds at least one preset critical value, automatically lowers the temperature in the vehicle and contacts the driver/caregiver and/or emergency personnel. The system detects the presence of a child in the closed vehicle by detecting a critical level of carbon dioxide in the air within the vehicle, while monitoring the interior vehicle temperature and takes corrective action to prevent the temperature from exceeding a preset value, such as by activating the vehicle'"'"'s air conditioning unit and lowering the vehicle'"'"'s windows, as well as contacting the driver/caregiver and/or emergency personnel.
