Abstract

Described is a device including a processor, a wireless arrangement including an antenna, and a memory arrangement storing first data and second data. The first data includes predetermined antenna characteristics and the second data includes predetermined triggering characteristics for triggering a function of the device. When third data fails to match the first data, the processor compares the third data to the second data, the third data being indicative of characteristics changes of the antenna. The processor triggers a corresponding function of the device as a function of the third data and the second data.

Claims (26)

1. A device, comprising:

a processor;

a wireless arrangement including an antenna; and

a memory arrangement storing first data and second data, the first data including predetermined antenna characteristics, the second data including predetermined triggering characteristics for triggering a function of the device;

wherein when third data fails to match the first data, the processor compares the third data to the second data, the third data being indicative of characteristics changes of the antenna, and

wherein the processor triggers a corresponding function of the device as a function of the third data and the second data; and

wherein the third data is generated in response to a physical interaction with the antenna, and the physical interaction being one of a physical contact with the antenna by a foreign object and bringing the foreign object within proximity to the antenna, and wherein the foreign object is not part of the antenna.

2. The device of claim 1 , wherein the predetermined antenna characteristics are indicative of an ability of the antenna to transmit wireless signals.

3. The device of claim 1 , wherein the predetermined antenna characteristics are indicative of an ability of the antenna to receive wireless signals.

4. The device of claim 1 , wherein the predetermined antenna characteristics include at least one of impedance, electric field strength, magnetic field strength and radiation intensity.

5. The device of claim 1 , wherein the first data corresponds to a characteristic impedance of the antenna and the second data corresponds to a change in the characteristic impedance caused by a user interaction with the antenna.

6. The device of claim 1 , wherein the third data is acquired by one of an envelope detector and a vector demodulator.

7. The device of claim 1 , wherein the third data is acquired by measuring a reflected signal of the antenna.

8. The device of claim 1 , wherein the second data comprises a user profile including at least one user-selected triggering characteristic.

9. The device of claim 1 , wherein the triggering of the function occurs when the third data matches the second data within a predetermined error margin.

10. The device of claim 1 , wherein the second data comprises a user profile including at least one user-selected triggering characteristic.

11. A method, comprising:

storing first data and second data in a memory arrangement of a device including an antenna and a processor, the first data including predetermined characteristics of the antenna, the second data including predetermined triggering characteristics for triggering a function of the device;

comparing the first data to third data, wherein when the third data fails to match the first data, the processor compares the third data to the second data, the third data being indicative of characteristics changes of the antenna;

triggering a corresponding function of the device when the third data matches the second data; and

wherein the third data is generated in response to a physical interaction with the antenna, and the physical interaction being one of a physical contact with the antenna by a foreign object and bringing the foreign object within proximity to the antenna, and wherein the foreign object is not part of the antenna.

12. The method of claim 11 , wherein the predetermined antenna characteristics are indicative of an ability of the antenna to transmit wireless signals.

13. The method of claim 11 , wherein the predetermined antenna characteristics are indicative of an ability of the antenna to receive wireless signals.

14. The method of claim 11 , wherein the predetermined antenna characteristics include at least one of impedance, electric field strength, magnetic field strength and radiation intensity.

15. The method of claim 11 , wherein the first data corresponds to a characteristic impedance of the antenna and the second data corresponds to a change in the characteristic impedance caused by a user interaction with the antenna.

16. The method of claim 11 , wherein the third data is acquired by one of an envelope detector and a vector demodulator.
