Abstract: Systems and methods for correcting uniformity of a cured tire using ablation of material along a plurality of tracks along the bead portion of the tire are provided. An ablation pattern can be determined to correct for a uniformity parameter for multiple tracks along a bead portion of a tire. The ablation pattern for each track can be analyzed to determined direct address commands for implementing the ablation pattern using an ablation device. The direct address commands can be determined according to an adjustment process to improve cycle time for the ablation of a tire. The adjustment process can be operable to more closely align azimuthal positions of ablation segments specified by direct address commands for different tracks along the bead of the tire.

Abstract: In a method for determining conditions of a road and a tire, a measurement of a sound signal produced by the tire running on the road during a timeframe is recorded, and a spectral density of a power of the sound signal over a frequency interval is determined. The frequency interval is segmented into frequency bands, and each frequency band is associated with a representative data element representing a mean acoustic power measured in the frequency band. The representative data elements obtained from the measurement form variables of a vector associated with the measurement. A road condition and a tire condition are determined via a discriminant analysis of the representative data elements using a learning base. Each representative data element is obtained by finding a ratio between a mean acoustic power measured in a corresponding frequency band and a total acoustic power measured over an entirety of the frequency interval.
