Patents by Inventor Grady Powers

Grady Powers 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).

  • Flexible electromagnetic acoustic transducer sensor
    Patent number: 7165453
    Abstract: An array of magnets designed of flexible components and materials can be easily shaped to fit to the contour of various curved surfaces and structures. EMATs that incorporate these magnets, in addition to being flexible, may be smaller in volume than the conventional EMAT magnets and therefore easier to apply to complex structures where access may be restricted. Also, flexible multiple-pole magnet arrays can be easily and economically fabricated in various shapes and configurations, thereby increasing versatility, utility and cost effectiveness in comparison to the rigid, conventional magnet designs.
    Type: Grant
    Filed: July 20, 2005
    Date of Patent: January 23, 2007
    Assignee: Electric Power Research Institute
    Inventors: John Flora, Muhammad Ali, Grady Powers
