Abstract: A tire defect tester and a method of operation are disclosed. In one aspect, the tire defect tester includes a first electrode arranged to direct energy toward a tire, and a second electrode arranged on an opposite side of the tire from the first electrode to receive energy passing through the tire from the first electrode. The tire defect tester further includes an energy sensor electrically connected to the second electrode and a fault indicator circuit responsive to the energy sensor and configured to indicate the presence of a flaw upon energy above a threshold level being sensed at the second electrode.

Abstract: An electrical discharge testing system for detecting electrical discharge rate failure in an electrical-based tire defect tester. The electrical discharge testing system generally includes a probe which is connected to a power source such that the probe periodically discharges electricity for the purpose of testing a tire for defects. A sensor detects each electrical discharge of the probe. To ensure that the probe is discharging at an appropriate rate for efficient coverage of the tire, a timer is preset to a threshold period of time between electrical discharges. The timer is reset each time an electrical discharge from the probe is detected by the sensor. If the timer reaches zero before a subsequent electrical discharge after a reset, an indicator is activated to indicate a fault in the tire defect tester.

Abstract: An improved biased electrode (54) as used in a tire defect tester (12) is the subject of this patent application. The electrode (54) is movable between a first position located within a circle circumscribed by the beads (28) of a tire (26) being tested and a second position received in a cavity between the sidewalls (30) of the tire (26) in engagement with an underside of the tread portion (38) of the tire (26). The electrode (54) includes at least one, and, in a preferred embodiment, two, elongated member (72). The member (72) is pivotally mounted so that, as the electrode (54) is moved from its first to its second position, a first arm portion (80) will engage the underside of the tread portion (38) of the tire (26) and cause the element (72) to pivot so that it is in engagement with the underside of the tread portion (38) substantially along the length of the element (72). During operation, an electric charge is given to the electrode (54), thereby imposing a potential across the electrode (54) and a neutral reference electrode (36) positioned on the other side of the tread portion (38) of the tire (26). If defects exist in the portions of the tire (26) sandwiched between the electrodes (36, 54), an arc will occur thereacross.

Abstract: A tire defect detection system for detecting defects in a tire. The system includes at least one infrared camera, a pneumatic source and a computing device. The pneumatic source inflates the tire to a predetermined pressure. After inflation, the infrared camera captures a reference frame of a section of the tire. A period of time after capturing the reference frame, the infrared camera captures a subsequent frame. The subsequent frame is compared to the reference frame to detect a portion of the section of the tire that has a lower temperature. The lower temperature is caused by an escape of air from the tire through a defect. The escaping air cools the area of the tire around the defect, so a decrease in temperature indicates the defect.
