A. device (502) includes a parameter detector (512), an input component (514), an accessing component (316), a comparator (518) and an identifier (520). The parameter detector (512) detects a first parameter and a second parameter and can generate a detected parameter signature based on the first detected parameter and the second detected parameter. The input component (514) can input the detected parameter signature into a database (504). The accessing component (516) can access the detected parameter signature from the database (504). "The comparator (518) can generate a comparison signal. The identifier (520) can identify a location based on the comparison signal. The parameter detector (512) can further detect a third parameter and a fourth parameter and can generate a second detected parameter signature based on rise third detected parameter and the fourth detected parameter. The comparator (518) can generate the comparison signal based on the detected parameter signature and the second detected parameter signature. |
