    摘要: A condition monitoring method for an electrical machine is provided. The method includes providing at least one first sensor element embedded in or disposed on at least one substrate element located in a stator core for obtaining a first set of data. The method also includes providing at least one second sensor element for obtaining a second set of data from the electrical machine. Further, the method includes generating signals indicative of changes in characteristics of the first sensor element based on the second set of data. Finally, the method includes refining the first set of data by combining the first set of data with the generated signals.

    摘要: A micro-electro-mechanical system (MEMS) current sensor for sensing a magnetic field produced by an electrical current flowing in a conductor includes a first fixed element and a moving element. The moving element is spaced away from the first fixed element and is movable relative to the fixed element responsive to a magnetic field produced by an electrical current flowing in a conductor for providing a mechanical indication of a strength of the magnetic field. The sensor also includes a tunneling current generator for generating a tunneling current between the first fixed element and the moving element and a tunneling current monitor for monitoring a change in the tunneling current responsive to the mechanical indication to provide an indication of a value of the electrical current in the conductor.

    摘要: A system to monitor the health of a structure, health monitoring sensor nodes, program product, and associated methods, are provided. The system includes an array of health monitoring sensor nodes connected to or embedded within a structure to monitor the health of the structure. Each health monitoring sensor node includes sensor elements positioned to sense parameters of the structure and to provide data related to the parameters to a health monitoring sensor node interrogator. Each health monitoring sensor node includes a processor or other means to reduce raw sensor data to thereby reduce communication bandwidth requirements and data collisions, and can include memory or other storage for storing the reduced data and an antenna arrangement for providing the reduced data to the health monitoring sensor node interrogator.
