Patent ID: 7710277

Claim:
A system for detecting and signaling that an animal or human is in an enclosed space, which comprises: a monitoring device for monitoring temperature in an enclosed space wherein the monitoring device specifies an unacceptable temperature for the enclosed space; an infrared device for detecting a presence of a human or animal in the enclosed space when the unacceptable temperature is reached, where the presence of an immobile human or animal trips the infrared device by temperature differences associated with thermography; and a detection circuit responsive to the monitoring device and the infrared device; and the detection circuit determines a state of operation in which said unacceptable temperature is reached and said infrared device is not tripped, wherein in said state of operation the infrared device scans and images the enclosed space to obtain a first infrared image and after a period of time a second infrared image wherein the first and second images are compared to detect the presence of the animal or human by movement by the detection circuit; and a signaling device responsive to the detection circuit for communicating a signal to a receiver outside the enclosed space indicating the presence of the human or the animal in the enclosed space when the unacceptable temperature is reached and presence of an immobile or moving animal or human is detected.
