Abstract

A method and apparatus for automatically determining a hazardous environmental condition within a container, such as a vehicle, and initiating alarm devices. In one embodiment, temperature, motion, acoustic, and pressure sensors in a vehicle output sensor signals to associated sensor threshold monitors. When a sensor threshold is exceeded, a sensor threshold monitor sends a threshold signal to a sensor collection logic device. The sensor collection logic device determines whether to initiate an alarm process based on whether the threshold signals indicated a hazardous environmental condition within the vehicle. In one embodiment, upon a determination to initiate the alarm process, the sensor collection logic device sends an alarm signal to an alarm processor which automatically initiates output signals to alarm devices, such as an audible alarm. In some embodiments, the output signals can further automatically unlock doors of the vehicle, retract windows of the vehicle, and automatically notify emergency personnel, such as police and emergency responders, of the location of the vehicle.
