    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: Use of a single line for switching multiple monitoring elements on/off, and a single line for sending signals to, or receiving signals from, those elements that are switched on. Monitoring elements each have an associated switching element, and each switching element is connected to a common switching line, or control line. A signal from the control line turns each switch on or off. Each monitoring element is also connected to a single signal line, and only those monitoring elements that are turned on can transmit/receive data signals along this signal line.

    摘要: Sensors affixed to various such structures, where the sensors can withstand, remain affixed, and operate while undergoing both cryogenic temperatures and high vibrations. In particular, piezoelectric single crystal transducers are utilized, and these sensors are coupled to the structure via a low temperature, heat cured epoxy. This allows the transducers to monitor the structure while the engine is operating, even despite the harsh operating conditions. Aspects of the invention thus allow for real time monitoring and analysis of structures that operate in conditions that previously did not permit such analysis. A further aspect of the invention relates to use of piezoelectric single crystal transducers. In particular, use of such transducers allows the same elements to be used as both sensors and actuators.
