Abstract

Embodiments of the invention provide novel, industrially applicable, and non-obvious apparatus and methods for automatically, routinely, and accurately calibrating a trace detection portal. Embodiments of the apparatus include a calibrant container; a substance (or substances) uniquely identifiable by a trace detection portal as a calibrant; unique placement of the calibrant container's outlet relative to a substance collection port of a sample collection chamber; and/or computer executable instructions that, when executed by a computer processor, cause a consistent release of a measured amount of calibrant into the sample collection chamber upon command and/or at pre-determined time intervals.

Claims (27)

1. A method for self-calibrating one or more components of a trace detection portal that includes a sample collection chamber, the method comprising:

receiving a signal from a controller coupled with the trace detection portal;

releasing a predetermined amount of a substance from a calibrant container into the sample collection chamber in response to the signal received from the controller;

detecting and analyzing the substance;

identifying the substance as a calibrant; and

automatically initiating a self-calibration of one or more components of the trace detection portal in response to the identification of the calibrant.

2. The method of claim 1 , further comprising:

generating a “clear” signal if the one or more components are each functioning properly; and

indicating via a display panel or other communication means that the trace detection portal is ready to process a person.

3. The method of claim 2 , further comprising:

setting a timekeeping device to transmit the signal to the calibration apparatus after an expiration of a predetermined period of time.

4. The method of claim 1 , further comprising:

generating a “fault” signal if one of the one or more components is malfunctioning; and

at least one of resetting the malfunctioning component(s) and repairing the malfunctioning component(s).

5. A method, comprising:

configuring a trace detection portal to detect and uniquely identify a calibrant and to automatically self-calibrate one or more components of the trace detection portal upon the identification of the calibrant from particles of interest collected from within a sample collection chamber of the trace detection portal; and

coupling an outlet of a calibrant container with the sample collection chamber.

6. The method of claim 5 , wherein the step of coupling an outlet of the calibrant container with the sample collection chamber comprises one of:

detachably coupling the outlet of the calibrant container with the sample collection chamber, and

fixedly coupling the outlet of the calibrant container with the sample collection chamber.

7. The method of claim 5 , further comprising:

insulating the calibrant container from heat generated by one of the one or more components of the trace detection portal.

8. The method of claim 5 , further comprising:

thermally connecting the calibrant container to absorb heat generated by one of the one or more components of the trace detection portal.

9. A method for calibrating a trace detection portal, the method comprising:

providing a calibrant container having an outlet; and

releasably storing a calibrant within the calibrant container, wherein the calibrant is a substance the trace detection portal is configured to detect and uniquely identity as a calibrant, and which causes one or more components of the trace detection portal to self-calibrate.
