Latest Patents

One of his latest patents is titled "Method for approximating tire flat spot decay and magnitude using regressive analysis." This innovative method enhances the determination of an initial flat spot magnitude on a tire that has been resting on a flat surface for an extended period. By utilizing regression analysis, the method determines values of tire flat spot magnitude at various measurement intervals using a uniformity machine that spins the tire. An equation with at least two exponentially decaying terms is derived from the measured data points. This regression analysis provides an estimate for the initial flat spot magnitude, allowing for the evaluation of different tire designs concerning flat spot recovery rates.
