  • Apparatus, systems, and methods for determining nonlinear properties of a material to detect early fatigue or damage
    Patent number: 11092573
    Abstract: An inspection apparatus detects one or more characteristics of a material sample and includes a transmitter to transmit an initial signal to the material sample, and a receiver to receive a detected signal from the material sample associated with the initial signal. The detected signal has at least a first harmonic signal component and a second harmonic signal component. Data processing circuitry determines a resonant frequency of the first harmonic signal component and an amplitude of the first harmonic signal component at the resonant frequency, and filters the detected signal using a first filter signal having a frequency corresponding to the first harmonic signal component and a second filter signal having a frequency corresponding to the second harmonic signal component. A frequency analysis is performed in the frequency domain on the filtered first and second signals to determine corresponding first and second amplitudes. The first and second amplitudes may be compensated for nonlinearity.

  • Method and apparatus for non-destructive detection of tire anomalies
    Patent number: 9909953
    Abstract: An impact-acoustic method for testing a tire is provided along with a tire anomaly detection system in which an actuatable impactor is provided with an acoustic transducer and a force transducer. A plurality of discriminator quantities is calculated from acoustic signals and force signals and the calculated discriminator quantities are compared with stored discriminator quantities to determine whether an anomaly is present in the tire.
