Abstract: The subject matter of the present invention relates to an integrally formed tire sensor container (100) for holding a tire sensor on the inner liner surface (70) within the cavity of a pneumatic tire (10). The container (100) has a base surface (110) surrounded by a peripheral wall (120) that extends from the base (110). An aperture (130) is formed by the peripheral wall (120) and has a maximum aperture diameter (132) smaller than a maximum wall diameter (126).

Abstract: A sensor device is provided for use in tire inspection. The sensor device is configured for removable placement along the inner surface of the tire. The sensor device includes multiple rows of sensors, which are used to provide signals that can compensate for the effect of vibrations or mechanical agitation as the sensors are passed over the inner surface of the tire. The sensor device may have a profile that allows for placement of the multiple rows of sensors in close proximity to the inner surface of the tire.

Abstract: A method of using a sensor device for tire inspection is provided. Signals are received from multiples rows of sensors separated by a predetermined distance. The sensors are positioned next to the inner surface of the tire for inspection. Signals from the different rows of sensors are used to identify e.g., breaks in the reinforcements of the tire and also used to identify undesirable signals generated from vibration or jarring of the sensor device.

Abstract: A sensor device is provided for use in tire inspection. The sensor device is configured for removable placement along the inner surface of a tire. The sensor device has a profile that allows placement of one or more sensors in close proximity to the inner surface of the tire. The profile allows the sensor device to be used with a variety of tire sizes and shapes.

Abstract: A sensor device is provided for use in tire inspection along a bead portion of the tire. The sensor device includes a magnet array configured to provide the desired fields of magnet flux for a sensor array, which is used to detect damage to reinforcements of a body ply of the tire near the bead portion. The fields of magnetic flux are sufficient to provide for damage detection in the bead portion without overly saturating the sensor array. The sensor device also allows for positioning the sensor array proximate to the inner surface of the tire for improved detection.

Abstract: A device is provided for placing one or more sensors along the inside surface of a tire. The device can accommodate tires of different shapes and sizes as well as projecting features along the inside surface of the tire. In one embodiment, sensors can be inserted into the interior of the tire and simultaneously deployed along the inside surface of both sidewalls. This embodiment of the device allows for repeated insertion and withdrawal of the sensors over a range of tire sizes so as to automate steps in the inspection process.

Abstract: A tire testing apparatus and method for detecting anomalies in the surface of a tire is disclosed. A high voltage probe having a conductive spring electrode is placed adjacent a portion of a tire surface such that the conductive spring electrode is compressed against the surface of the tire. Relative motion is imparted between the high voltage probe and the surface of the tire. An electrical discharge occurs between the high voltage probe and a reference electrode at the location of an anomaly on the surface of the tire. The apparatus and method are configured to determine a precise azimuthal and radial position on the tire of the electrostatic discharge. The conductive spring electrode can have a length sufficient to ensure contact with a given point on the tire surface during a charge cycle for the high voltage probe at increased tire surface speeds.

Abstract: A tire surface anomaly detection system and method are disclosed. The system and method are generally based on the principle that a tire surface anomaly will have a different heat transfer rate than that of the uniform mass surrounding the tire surface anomaly. Embodiments of the present disclosure apply thermal energy to the surface of a tire and monitor the infrared energy at the surface of the tire to generate one or more infrared images of the surface of the tire. The infrared images are analyzed by an image processing system to determine and locate thermal gradients on the surface of the tire. The presence of a thermal gradient in the infrared images generally indicates the presence of an anomaly in the surface of the tire. In this manner, the present disclosure provides an objective technique for identifying, locating, and classifying tire surface anomalies.

Abstract: An apparatus and method for high voltage discharge testing of a tire is disclosed. In particular embodiments, a high voltage probe is maintained against the surface of a tire. The high voltage probe is energized and relative motion is provided between the surface of the tire and the high voltage probe. At the presence of an anomaly that penetrates the insulating material of the tire surface, an electrical discharge will occur between the conductive spring electrode and a reference electrode. The reference electrode is positioned adjacent the bead portion of the tire such that the electrical discharge will travel from the high voltage probe through the anomaly in the surface of the tire to one or more carcass plies in the tire. The carcass plies will carry the electrical discharge to the bead portion of the tire, where the electrical discharge will pass to the reference electrode.
