Latest Patents

Patrick H Johnston holds a patent for a "Floating ultrasonic transducer inspection system and method for nondestructive evaluation." This invention involves a method for inspecting structural samples using ultrasonic energy. The process includes positioning an ultrasonic transducer adjacent to the sample's surface and transmitting ultrasonic energy into the sample. Concurrently, force pulses are applied to the transducer while the ultrasonic energy is transmitted. A host machine processes the ultrasonic return pulses to quantify the attenuation of the ultrasonic energy within the sample. This method allows for the detection of defects based on the quantified level of attenuation. The system also incorporates a dry couplant between the transducer and the sample, along with a scanning device and a measurement system that executes the inspection method.
