Latest Patents

Rainey's most recent patent is for a "Walking-gate ultrasonic flaw detector." This microprocessor-based ultrasonic inspection system reliably detects fatigue cracks smaller than 0.030 inch under installed fasteners. The invention utilizes a unique signal-processing method that takes advantage of the fact that crack signals 'walk' in time as a transducer moves around a fastener. By analyzing bolt size, scan depth, and the angle of incidence of an ultrasonic shear wave, the system determines the 'walk rate' of a defect in the inspection zone. This geometric information allows the signal-processing technique to enhance any pulse-echo return 'walking' at the computed walk rate, significantly improving the ratio of crack signal to other signal sources in the material.
