Abstract:
A method of providing an automated, wide area, danger warning and emergency response comprising the steps of:(a) detecting a dangerous situation from a detection location,(b) transmitting information signals describing the dangerous situation from the detection location via radio transmission signals to a control center for analysis,analyzing the received information signals in the control center in computer systems employing expert system technology,(d) determining in the control center the degree of danger and its geographic extent based on analysis of the received information signals,(e) generating in the control center a danger warning and emergency response including a danger index indicating a degree of danger within at least one geographic area,(f) broadcasting the danger warning and emergency response from the control center to a plurality of remotely located warning devices each of which has a GPS receiver and the ability to calculate its own location in GPS coordinates,(g) receiving via the broadcast signals the danger warning and emergency response in the remotely located warning devices, and comparing in each remotely located warning device the coordinates of the dangerous situation with its own GPS coordinates for determining the extent to which each remotely located warning device is in danger, and(h) automatically issuing from each remotely located warning device a warning corresponding to the extent to which the issuing remotely located warning device is in danger.
