Dynamic Canine Tracking Method for Hazardous and Illicit Substances

Abstract

Vapor wake detection is a highly advantageous method and system for detecting explosives and other illicit substances. With vapor wake detection, a canine and a handler are used; however, unlike other detection schemes, the canine leads the handler. After the handler positions the canine in a desired location, the canine detects scents in the air that come to the canine. When the canine detects a trained scent, the canine leads the handler to or follows behind the carrier of the item with the scent. Once the carrier is identified by the handler, the proper personnel are contacted. To implement vapor wake detection effectively, specific rigorous training is utilized.

1 .- 19 . (canceled) 
     
     
         20 . A method of training a canine for detection, the method comprising:
 choosing a detector canine that demonstrates a high level of sniffing capabilities;   teaching the detector canine that the source of a target odor is not limited to stationary objects, and teaching the detector canine to not search stationary objects, wherein the source of the target odor is a hazardous or illicit substance;   teaching the detector canine to follow a vapor-wake of a moving target, wherein the vapor-wake includes the target odor of the moving target;   teaching the detector canine to sample air currents; and   teaching the detector canine to lead a handler to the source of the target odor, where the source of the target odor comes within a detectable range of the detector canine.   
     
     
         21 . The method of  claim 20 , further comprising choosing the detector canine that demonstrates a high level of independent search behavior, further including choosing canines that are motivated to sniff and search independently in a manner to disguise their handlers. 
     
     
         22 . The method of  claim 21 , wherein choosing the detector canine that demonstrates a high level of independent search behavior further includes choosing canines that are not overly sociable. 
     
     
         23 . The method of  claim 20 , wherein the method further includes teaching the detector canine to search the air for vapor trails or scent pools of the target odor generated by a moving or stationary target. 
     
     
         24 . The method of  claim 20 , wherein the method further includes teaching the detector canine to accommodate dissipation of the target odor over time. 
     
     
         25 . The method of  claim 20 , further comprising teaching the detector canine to follow the vapor-wake to the target and give a final response. 
     
     
         26 . The method of  claim 20 , further comprising choosing the detector canine that passes a medical examination. 
     
     
         27 . The method of  claim 26 , wherein the medical examination includes testing to dexterity and freedom from bone, joint and musculature pathologies.
