Abstract

The present invention is a method and apparatus for the detection of portable electronic device functionality. In a preferred embodiment, the present invention includes a chemically coated antenna to serve as a trigger for device functionality detection. The chemically coated antenna may be passively or actively detected. In active detection, a detection apparatus releases a chemical which reacts or otherwise respods with the chemical trigger in a detectable manner. The detection apparatus detects the reaction, which is specific to the functionality of the portable electronic device. In passive detection, a detection device simply detects the chemical trigger, which is specific to the portable electronic device functionality. Other trigger embodiments utilizing optics, radio frequency (RF) signals, sound waves, and magnetic identification are also disclosed.

Claims

1. A method in an apparatus for detecting the functionality of an electronic device, comprising:

detecting a trigger from the electronic device wherein the electronic device is separate from the apparatus;

identifying one or more functionalities of the electronic device based on the detected trigger;

for each of the one or more functionalities, determining whether the functionality is permitted or restricted in a protected area; and

in response to a determination that at least one of the one or more functionalities is restricted in the protected area, setting an alert flag indicating that the electronic device includes restricted functionality.

2. The method of claim 1, wherein the trigger is a chemical layer applied to the electronic device.

3. The method of claim 2, wherein the chemical layer is a coating applied to an antenna of the electronic device.

4. The method of claim 2, wherein the chemical layer is a coating applied to a retractable strip of the electronic device.

5. The method of claim 2, wherein the apparatus is a mass spectrometer.

6. The method of claim 1, wherein the trigger is an optical filter.

7. The method of claim 6, wherein the optical filter is integrated into an antenna of the portable electronic device.

8. The method of claim 1, wherein the trigger is an RF transmission.

9. The method of claim 1, wherein the trigger is a sound transmission outside of the range of human hearing.

10. The method of claim 1, wherein the trigger is a magnetic matrix identifier.

11. A method in an apparatus for detecting the functionality of an electronic device, comprising:

activating a trigger provided on the electronic device to create a response, wherein the electronic device is separate from the apparatus;

detecting the response of the activated trigger; and

identifying one or more functionalities of the electronic device based on the detected response;

for each of the one or more functionalities, determining whether the functionality is permitted or restricted in a protected area; and

in response to a determination that at least one of the one or more functionalities is restricted in the protected area, setting an alert flag indicating that the electronic device includes restricted functionality.

12. The method of claim 11, wherein the trigger is a chemical layer applied to the electronic device.

13. The method of claim 12, wherein the chemical layer is a coating applied to an antenna of the electronic device.

14. The method of claim 11, wherein the chemical layer is a coating applied to a retractable strip of the electronic device.

15. The method of claim 12, wherein the apparatus is a mass spectrometer.

16. The method of claim 12, wherein the trigger is activated by emanating a chemical that is reactive with the trigger, causing a detectable chemical reaction.

17. The method of claim 16, wherein the detectable chemical reaction is a change in the heat signature of the chemical marker.

18. The method of claim 16, wherein the detectable chemical reaction is a color change in the chemical marker.

19. The method of claim 16, wherein the detectable chemical reaction releases a byproduct that is detectable by the apparatus.

20. The method of claim 11, wherein the trigger is an optical filter.

21. The method of claim 20, wherein the optical filter is integrated into an antenna of the portable electronic device.

22. The method of claim 20, wherein the apparatus detects the trigger by sensing light filtered through the optical filter.

23. The method of claim 11, wherein the trigger is an RF transmission.

24. The method of claim 11, wherein the trigger is a sound transmission outside of the range of human hearing.

25. The method of claim 11, wherein the trigger is a magnetic matrix identifier.

26. An apparatus for detecting the functionality of an electronic device, the apparatus comprising:

an activator configured to activate the trigger of the electronic device, wherein the electronic device is separate from the apparatus and includes a trigger, the apparatus comprising;

a sensor configured to;

detect the activation of the trigger;

identify one or more functionalities of the electronic device;

for each of the one or more functionalities, determine whether the functionality is permitted or restricted in a protected area; and

in response to a determination that at least one of the one or more functionalities is restricted in the protected area, set an alert flag indicating that the electronic device includes restricted functionality; and

an interface configured to output the one or more functionalities of the electronic device.

27. The apparatus of claim 26, wherein the activator releases a chemical that reacts with the trigger producing a byproduct gas and the sensor detects the byproduct gas.
