Wilhelmina C. Leuschen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10495564
    Abstract: A method and apparatuses to make an in-service measurement of the thickness and corrosion rate of the floor an aboveground or bulk underground storage tank. The preferred method is to use an off-the-shelf ultrasonic sensor that is placed on the end of a staff and inserted into an opening at the top of the tank to make one or more local measurements of the thickness and corrosion rate of the tank floor. When combined with the results of a previous out-of service internal inspection of the floor or an acoustic emission (AE) corrosion activity test performed with a vertical and horizontal array of three or more AE sensors placed on a staff and inserted into the liquid or on the external wall of the tank and show almost no corrosion activity, these local measurements can be used to determine the thickness and corrosion rate for the entire tank floor.

  • Patent number: 9811900
    Abstract: A method and an apparatus for automatically collecting and processing nondestructive test (NDT) data to determine the presence, type, location, size, and strength of defects in composite, honeycomb, and grid structures like those found in aircraft, wind blades, boats, cars, building structures. The preferred embodiment is comprised of an uncooled IR mounted on a frame, a conductive heating mat, an IR Ruler with fiducials in a recognizable pattern, a computer, a processor, and output displays. The data collection, processing, and display output can be controlled or reviewed remotely via the internet. The processing, location, and output displays can be applied to any NDT system that collects and processes a two dimensional amplitude image (e.g., x-ray systems).

  • Patent number: 9004753
    Abstract: A method and an apparatus for detecting defects in the composite materials of a wind turbine blade or similar type of structure using an infrared (IR) camera. The temperature of the wind turbine blade is changed in such a way as to produce IR intensity changes in the region of the defect that can be visually detected or detected using a computer and signal processing algorithms. The same approach will work on other composite structures such as those found on aircraft.
