  • Frame crack detection method
    Patent number: 7559250
    Abstract: A method for detecting a crack in a frame is disclosed. The method includes sensing with a first pressure sensor a first pressure within a first sealed cavity. The first sealed cavity is interior to a first structure of the frame. Additionally, the method includes detecting a first change in the sensed first pressure. The method also includes determining preliminarily that a crack has formed in the first structure based on the detected change in the sensed first pressure. In addition, the method includes determining a criticality of the crack.
