Patent ID: 8884813

Claim:
A surveillance system, comprising: a micro-impulse radar configured to survey a region; and a controller configured to, receive an input signal from the micro-impulse radar, extract from the signal one or more physical or physiological attributes of more than one person corresponding to a human stress condition, compare the extracted one or more physical physiological attributes of the more than one person corresponding to the human stress condition to calculate a statistical average value of the one or more physical or physiological attributes corresponding to the human stress condition, determine if the extracted one or more physical or physiological attributes corresponding to the human stress condition indicate a predicted human stress condition for at least a single person in the region at least partially based on the statistical average value by determining if the extracted one or more physical or physiological attributes corresponding to the human stress condition for the at least a single person in the region fall outside of a predetermined deviation from the statistical average value, and base at least in part on the determination of whether or not the one or more physical or physiological attributes corresponding to the human stress condition for the at least a single person fall outside of the predetermined deviation, output a notification signal.
