    摘要: A sensor array embedded within a flexible layer. The sensors, which can be transducers, are controlled by local electronics also embedded within the flexible layer. The invention includes numerous different arrangements of these electronic controllers and their associated transducers. For example, each transducer can have its own controller embedded nearby. Alternatively, one controller can control a number of transducers, and can therefore be embedded in various configurations proximate to one or more of the transducers it controls. The controllers can include various components that impart other advantages, such as wireless transceivers for reducing the number of wires needed within the flexible layer, and local processors for reducing or eliminating the need for a remote data processor.

    摘要: Storage of information, such as baseline information and structure ID, in a memory that is mounted on the structure, rather than inside the diagnosis hardware. This allows for faster and more convenient information retrieval. In particular, this approach allows for a more modular system in which different diagnosis hardware or other analyzers can be simply plugged into a structure's sensor network, whereupon they can quickly download any desired structure-specific information (e.g., baseline information, structure ID, and other useful information) from the on-structure memory.

    摘要: A method for both detecting and analyzing a change in the loading condition of a structure. A flexible substrate is employed, in which a distributed network of sensors is built. This substrate is either affixed to the surface of the structure, or built within it, so as to be able to detect propagating stress waves. After load change is detected, the resulting sensor signals are analyzed to determine the location, severity, and/or any characteristic frequencies of the load change. This information is then used to determine an appropriate response.

    摘要: A method of performing transducer self-diagnostics and self-healing on an array of sensor transducers bonded to a structure for health monitoring includes measuring impedance to detect whether a transducer is missing, or a connection is damaged. Pitch-catch signals generated between one or more pairs of transducers are analyzed for detecting defects according to selected criteria of defect size and location to determine whether the sensors are damaged or partially/fully disbonded. Based on the resulting map of operational transducers, signal transmission paths are added/extended between additional pairs of transducers to maintain inspection coverage of the structure according to the selected criteria.
