Description
Animal Scent Detection Apparatus and System Inventor: David Reese BACKGROUND
Field of the Invention The present invention relates generally to the field of scent detection and more particularly to a animal scent detection system.
Description of the Prior Art It is well known to use dogs or other animals to search for contraband such as drugs or explosives. This is because animals have noses that are far more sensitive and responsive to a wide variety of materials than humans.
Dogs, for example, are know to be able to detect various materials in the parts per billion range. Canines have been used particularly because they can be trained to respond in a predetermined manner when they detect the presence, of a target substance.
In the modern world, it is becoming more and more important to be able to detect drugs, explosives and other contraband that produces a detectable scent. This is particularly true at airport security check points, national border entry points and other key locations where people and vehicles need to be checked.
It is also important to law enforcement personnel to be able to find hidden contraband in premises or business searches or find explosives of contraband in containers and vehicles.
One problem with simply having a dog sniff for substances in hand carried luggage or at a check point is that such a procedure may annoy or frighten an innocent person, or it might even be an unacceptable invasion of t privacy. This is particularly true in a place like an airport security check point where numerous people of all ages and genders routinely pass through. A
second problem arises in buildings where target substances may be hidden out of smelling range of an animal walking on a leash (contraband hidden above ceiling tiles for example). This problem might even arise with persons passing through a check point if the substance was hidden on their body high enough to put it above the dog's smelling range.
It is known in the art to use a pass-through portal with air taken from the portal and passed to a dog or a machine. However, this technique is not portable for use in building searches, and it generally requires the dog to stay very near one point in the equipment such as an opening where air samples are directed.
It would be advantageous to have a portable apparatus that would allow security and law enforcement personnel to take advantage of the sensitivity and selectivity of a canine's nose (or any other animal) to detect trace scent from target materials such as explosives, drugs and the like while walking with the dog through the search area.

A particular embodiment of the present invention includes a muzzle-like device that fits over the dog's snout and can be loosely and comfortably strapped to its head. Air samples taken from a search area can be directed into a fan unit and through tubing to this device. Fig. 1 shows an example of this embodiment. A dog 17 wearing such a device 1 cooperates with a human operator 16 who wears a portable fan and battery unit 19 in a waist pack. Searching is performed by the operator 16 using a hose 8 and inlet pickup device 9. The small portable unit 19 runs on batteries and moves air from the pickup device 9 to the scent presentation device 1 on the dog's nose via a tube or hose 5. The dog can be trained to respond in a predetermined manner such as sitting upon detection of a target scent. The device can be operated by placing it on the dog, and starting the fans making generally sure that fresh air (with no contamination from any target substance) is entering the pickup. After airflow is established, the operator and dog can proceed to a search area. The portable unit 19 can be worn by the operator during the search. The operator-dog team can then proceed on foot to perform the search for contraband 18. While Fig. 1 shows a item on a table to aid in the understanding of the invention, in reality, contraband 18 may be hidden in walls or ceilings, under beds, in cabinets or anywhere.
A room can be searched quickly using the apparatus of the present invention by moving the pickup to the vicinity of points of interest including the walls or ceiling. The dog can be trained to give an indication of a detection by either moving its body (sitting for example), or by making some other type of indication. I raining of this type is unique in itself. Generally when a detection is made, the operator can optionally move away from the locus with the dog, make sure the pickup is pulling in only clean air at that point, wait until the dog has stopped responding, and then return to the suspect area. If the dog gives a second indication of a hit or detection, the operator or other personnel can search for the actual contraband.
Fig. 2 shows a detail of an embodiment of the muzzle-like scent presentation device that can be worn by the dog. The device can have a rigid metal or plastic frame 1 that is shaped to fit over an animals snout so that the nose is near the front of the device. The device can include an over-bar 16 that passes over the nose. Incoming airflow can enter a T-junction 6 that directs the flow into tubing 2 on each side. While tubing is shown in Fig. 2 on both sides, tubing on only one side is within the scope of the present invention. Holes 3 in the tubing 2 direct the flow to the nose. The holes or other presentation ports or means 3 can be far enough away from the nose so that the dog is comfortable and yet can detect target substances in the desired sensitivity range. The device can be fitted onto the animal's head with a harness 15 that can attach with one or more straps 4. The harness 15 and strap(s) 4 can be made from leather, artificial leather or any other flexible material. The strap can contain holes that mate into a buckle.
Fig. 3 shows an embodiment of a portable apparatus using the principles of the present invention. A central portable unit 7 can contain fans and provide an air moving point to pull air from an inlet hose 8 and pickup 9.
Air can move through the portable unit 7 and be forced out both sides to a junction 6 where it can enter a single feed hose S. The feed hose 5 can be

In the embodiments of Figs. 3-5, the battery 15 and the air moving unit
7 can be combined into a pack 19 that can be conveniently worn on the waist or back (shown in Fig. 1). Any other type of pack or of carrying the unit is within the scope of the present invention including straps on the air moving unit 7. In yet another embodiment, the battery can be reduced in size and located inside the air moving unit.
in some cases, the search area may be too large or full of materials or there may not be time to search it. In this case, larger fans can be used in the area to direct scents to the portable unit or through a larger hose directly to the animal's nose.
It should be noted in the embodiments of the present invention that the air moving unit can optionally be incorporated directly into an enlarged section of the hose if desired. Fig. 6 shows an embodiment of the invention containing this feature. A widened section of the tubing 7 can contain a miniature fan 11 or a fan 11 and battery 15.
Fig. 7 shows an optional auxiliary external fan unit 16 that has a larger fan or fans that is capable of moving a larger volume of air. This embodiment of the invention is useful for sweeping a large area that is possibly inaccessible such as a cargo container. The larger fan can pull the air out of the container 17 and then directly into the rest of the system as shown in Fig.
7. The external fan unit 16 can be made small enough to carry in the bag 19 (Fig. 1) with the rest of the equipment and plug directly into a fitting in a container or truck. The external fan unit 16 can also be used as a stand-alone unit if desired. The preferred capacity of the external unit is around 400 CFM;
however, any capacity is within the scope of the present invention.
It should be noted that the present invention finds many applications beyond the simple searching for contraband. In particular, the invention can be used to sweep for buried land mines, munitions and the like. An operator can use an extension to move the probe 10 out ahead of the dog by a reasonably safe distance. In this way, an operator and dog team can advance slowly in an area with buried mines sweeping ahead of them without
