Abstract
A system and method are provided for monitoring the physical integrity of a tire. The system and method include measuring a signal proportional to the speed of rotation of the wheel and calculating a harmonic signal of the round of wheel (e.g., equal to the energies of the harmonics of this signal), then comparing the result with a threshold and activating an alarm when over-passing this threshold.

52. A computer-readable medium storing computer-executable instructions for identifying a defect in the physical integrity of a tire on a vehicle, by performing operations comprising:
-
measuring a signal that is proportional to the speed of rotation of a tire to be monitored;
calculating harmonic information from said signal;
comparing the calculated harmonic information to a threshold; and
identifying that a defect exists in the physical integrity of the tire when the threshold is exceeded by the calculated harmonic information. - View Dependent Claims (53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67)
