Latest Patents

One of Nenno's latest patents is titled "Position-based sampling for eddy current inspection of steam generator tubes." This innovative method employs an eddy current sensor to inspect steam generator tubes by accelerating and decelerating the sensor in a predetermined manner. This approach significantly reduces the likelihood of damage to the sensor, thereby minimizing radiological waste and radiation exposure for workers involved in changing damaged probes. The system records eddy current signals at equally spaced locations along the tube, allowing for variable sensor velocity without compromising data validity.

Another significant patent is the "Inspection mode switching circuit." This eddy current probe testing apparatus operates concurrently in both driver pick-up mode and impedance mode. The eddy current probe features two coils and includes a signal-producing device, an output device, and a switch assembly. This design allows for inspections to be performed in two modes simultaneously, enhancing the efficiency of the testing process.
