Abstract

A system and method for observing, collecting and analyzing olefactory characteristics of a human or animal subject, such as sniffing, breathing and respiratory patterns and sounds. Example applications include the evaluation and training of dogs for explosive and drug detection, clinical diagnostics, scientific research, and identification.

Claims

1. A system for monitoring olfactory characteristics of a subject, the system comprising a transmitting microphone for attachment in a position generally overlying the olfactory epithelium of the subject, a receiver for receiving a signal indicative of an internal olfactory characteristic from the microphone, and a recorder for recording data corresponding to sounds from the olfactory epithelium as a function of the presentation of at least one stimulus presented to the subject.

2. The system of claim 1, further comprising a harness for attaching the microphone over the olfactory epithelium of the subject.

3. The system of claim 1, further comprising a display for displaying data corresponding to olfactory characteristics of the subject.

4. A method for monitoring olfactory characteristics of a subject, said method comprising the steps of attaching a microphone at or adjacent a nasal region of the subject, presenting at least one olfactory stimulus to the subject, receiving signals from the microphone corresponding to the olfactory characteristics of the subject, and recording data corresponding to the olfactory characteristics of the subject as a function of the presentation of the at least one olfactory stimulus.

5. The method of claim 4, further comprising monitoring states of sniffing by a dog subject, including a first state of searching for a target olfactory stimulus and a second state wherein the dog subject is presented with the target olfactory stimuli.

6. The method of claim 4, further comprising monitoring long-range detection of olfactory stimuli by a dog subject wherein sniff patterns of the subject change to alert a handler of the dog subject of the presence of a specific materials.

7. The method of claim 4, further comprising the step of monitoring breathing and the respiratory extent and rate of the subject.

8. The method of claim 4, further comprising the step of monitoring a respiratory dysfunction in the subject.

9. The method of claim 8, further comprising conducting a chemical analysis of exhaled breath of the subject.

10. The method of claim 4, wherein the microphone is attached in a position generally overlying the olfactory epithelium of the subject.

11. A system for monitoring olfactory characteristics of an animal, the system comprising:

a microphone mounted to a harness adapted to be worn by the animal; and

a computer for receiving signals from the microphone and outputting information related to an olfactory characteristic of the animal, wherein the information related to an olfactory characteristic of the animal includes a sniffing frequency of the animal, and wherein the computer compares the sniffing frequency of the animal with a target sniffing frequency.

12. The system of claim 11, wherein the system outputs an alert to a handler of the animal based on the comparison of the sniffing frequency of the animal with the target sniffing frequency.

13. The system of claim 11, wherein the harness holds the microphone over the olfactory epithelium of the animal.

14. A system for monitoring olfactory characteristics of an animal, the system comprising:

a microphone comprising a wireless transmitter;

a harness for mounting the microphone to the animal;

a receiver for receiving a signal from the wireless transmitter of the microphone;

means for recording data related to the signal;

means for processing said data; and

output means for generating an output from said means for processing, wherein said output means comprises an alarm for alerting a handler of the animal.

15. The system of claim 14, wherein the harness holds the microphone over the olfactory epithelium of the animal.

16. A system for monitoring olfactory characteristics of an animal, the system comprising:

a microphone comprising a wireless transmitter;

a harness for mounting the microphone to the animal;

a receiver for receiving a signal from the wireless transmitter of the microphone;

means for recording data related to the signal;

means for processing said data; and

output means for generating an output from said means for processing;

wherein said means for processing compares a sniffing characteristic of the animal to a target sniffing characteristic.

17. The system of claim 16, wherein the harness holds the microphone over the olfactory epithelium of the animal.

18. A method for monitoring olfactory characteristics of an animal, said method comprising:

collecting input data related to the animal'"'"'s olfaction using a microphone;

processing the collected data using a computer; and

outputting a signal from the computer related to an olfactory characteristic of the animal, wherein the step of outputting a signal comprises triggering an alarm for alerting a handler of the animal.

19. The method of claim 18 wherein the microphone is attached in a position generally overlying the olfactory epithelium of the animal.

20. A system for monitoring olfactory characteristics of an animal, the system comprising:

a microphone mounted to a harness adapted to position the microphone generally over the olfactory epithelium of the animal;

a computer for receiving signals indicative of characteristics of the olfactory epithelium of the animal from the microphone and outputting information related to the olfactory characteristic of the animal, wherein the information related to an olfactory characteristic of the animal includes a sniffing frequency of the animal and, wherein the computer compares the sniffing frequency of the animal with a target sniffing frequency.

21. A system for monitoring olfactory characteristics of an animal, the system comprising:

a microphone comprising a wireless transmitter;

a harness adapted holding the microphone in a position generally over the olfactory epithelium of the animal;

a receiver for receiving a signal indicative of an internal olfactory characteristic from the wireless transmitter of the microphone;

means for recording data related to the signal;

means for processing said data; and

output means for generating an output from said means for processing, wherein said output means comprises an alarm for alerting a handler of the animal.

22. A system for monitoring olfactory characteristics of an animal, the system comprising:

a microphone comprising a wireless transmitter;

a harness adapted holding the microphone in a position generally over the olfactory epithelium of the animal;

a receiver for receiving a signal indicative of an internal olfactory characteristic from the wireless transmitter of the microphone;

means for recording data related to the signal;

means for processing said data; and

output means for generating an output from said means for processing, wherein said means for processing compares a sniffing characteristic of the animal to a target sniffing characteristic.

23. A method for monitoring olfactory characteristics of an animal, said method comprising:

collecting input data related to olfactory epithelium sounds of the animal using a microphone;

processing the collected data using a computer;

outputting a signal from the computer related to an olfactory characteristic of the animal, wherein the step of outputting a signal comprises triggering an alarm for alerting a handler of the animal.
