Abstract

A system for tracking one or more subjects for collecting airborne contaminants. The system includes one or more subjects configured to collect air contaminants. Each of the one or more subjects includes an identification tag encoded with identification information identifying the each subject. The system further includes an identification reader configured to decode the identification information encoded within the identification tag of a scanned one of the one or more identification tags. A computer receives and stores the decoded identification information in a record in a database. The computer may also receive and stored an identification code for a user who scanned the scanned identification tag in the record in the database. Additional records in the database are created each time the identification tag of one of the one or more subjects is scanned. The one or more subjects are thereby tracked as they collect airborne contaminants and are incubated.

First claim

What is claimed is:

1. A system for tracking subjects that collect airborne particles, each of the subjects including a subject identification tag encoded with identification information identifying the each subject, the system comprising:
a plurality of air sampling devices, each configured to draw air over one of the subjects during air sampling;
an identification reader configured to scan one of the subject identification tags and decode the identification information encoded within the scanned subject identification tag;
a computer configured to receive and store the decoded identification information; and
a controller connected to each of the air sampling devices via vacuum lines that separately controls air flow rates at each of the air sampling devices.

2. The system of claim 1 , further comprising:
a plurality of inline flow control modules, each inline flow control module corresponding to one of the plurality of air sampling devices, each of the inline flow control modules configured to separately measure the air flow realized at the corresponding air sampling device,
wherein the controller is connected to each of the air sampling devices via one of the inline flow control modules.

3. The system of claim 1 , wherein:
the subjects are respectively disposed in one or more locations, each location comprising a location identification tag encoded with location information; and
the identification reader is further configured to:
scan the location identification tag in the location of the subject that includes the scanned subject identification tag; and
decode the location information encoded within the scanned location identification tag.

4. The system of claim 3 , wherein the computer is further configured to receive and store the decoded location information.

5. The system of claim 4 , wherein the computer is further configured to compare the decoded location information to the decoded identification information to determine whether the subject that includes the scanned subject identification tag is properly located.

6. The system of claim 5 , wherein the computer is further configured to transmit an indication of whether the subject that includes the scanned identification tag is properly located.

7. The system of claim 5 , further comprising:
a database for storing scanned information received from the identification reader,
wherein the computer is further configured store the decoded identification information and the decoded location information in a record in the database.

8. The system of claim 7 , wherein the computer stores a time stamp in the record in the database.

9. The system of claim 1 , wherein the computer is further configured to receive and store data obtained during the period when each air sampling devices draws air over each subject.

10. The system of claim 9 , wherein the data includes the air flow rate at each of the air sampling devices.

11. A method for tracking subjects that collect airborne particles, each of the subjects including a subject identification tag encoded with identification information identifying the each subject, the method comprising:
providing a plurality of air sampling devices, each configured to draw air over one of the subjects during air sampling;
providing a controller connected to each of the air sampling devices via vacuum lines;
scanning, by an identification reader, one of the subject identification tags;
decoding the identification information encoded within the scanned subject identification tag;
storing the decoded identification information;
separately controlling, by the controller, air flow rates at each of the air sampling devices; and
drawing air over the subject that includes the scanned subject identification tag.

12. The method of claim 11 , further comprising:
providing a plurality of inline flow control modules, each inline flow control module corresponding to one of the plurality of air sampling devices, wherein the controller is connected to each of the air sampling devices via one of the inline flow control modules; and
separately measuring, by the inline air flow control modules, the air flow rates at each of the air sampling devices.

13. The method of claim 11 , wherein the one or more subjects are respectively disposed in one or more locations, each location comprising a location identification tag encoded with location information, the method further comprising:
scanning, by the identification reader, the location identification tag in the location of the subject that includes the scanned subject identification tag; and
decoding the location information encoded within the scanned location identification tag.

14. The method of claim 3 , further comprising:
storing the decoded location information.

15. The method of claim 4 , further comprising:
comparing the decoded location information to the decoded identification information to determine whether the subject that includes the scanned subject identification tag is properly located.

16. The method of claim 5 , further comprising:
transmitting an indication of whether the subject that includes the scanned subject identification tag is properly located.

17. The method of claim 5 , further comprising:
storing the decoded identification information and the decoded location information in a record in a database.

18. The method of claim 7 , further comprising:
storing a time stamp in the record in the database.

19. The method of claim 1 , further comprising
receiving and storing, by the computer, data obtained during the period when each air sampling devices draws air over each subject.

20. The method of claim 9 , wherein the data includes the air flow rate at each of the air sampling devices.
