    摘要： A broad band energy harvesting system to harvest energy from a structure and associated methods are provided. The system includes a structure carrying a plurality of environmentally produced vibration frequencies extending over a frequency range and an energy harvesting apparatus positioned in vibration receiving communication with the structure to harvest energy from the structure. Each energy harvesting apparatus includes broadly tuned energy harvesting generators having relatively low quality factor and corresponding relatively wide bandwidth. The energy harvesting generators collectively provide energy harvesting over multiple modes to thereby provide energy harvesting over a substantial portion of the frequency range. Each energy harvesting generator can include a cantilevered beam connected to a common backbone comprised of a resilient material configured to transfer energy between adjacent generators to further enhance energy harvesting.

    摘要： A system to monitor the health of the structure, program product, and associated methods are provided. The system can include multiple health monitoring sensor nodes positioned to monitor parameters of a portion of the body of the structure. Sensor elements of the sensor nodes are spatially positioned along the body of structure at related or complementary locations to form a special correlative relationship between sensor nodes. The system can also include a data collector having a transceiver positioned to gather sensed parameter data from each of the sensor nodes, and a central computer including in memory, parameter process program product adapted to analyze the sensed parameter data, correlate the sensed parameter data to infer a state of health of the structure responsive to the correlation, and to detect or otherwise determine a type, severity, and/or location of damage to or incipient failure of the structure.

    摘要： A clearance measurement system is provided. The clearance measurement system includes a reference geometry disposed on a first object having an otherwise continuous surface geometry and a sensor disposed on a second object, wherein the sensor is configured to generate a first signal representative of a first sensed parameter from the first object and a second signal representative of a second sensed parameter from the reference geometry. The clearance measurement system also includes a processing unit configured to process the first and second signals to estimate a clearance between the first and second objects based upon a measurement difference between the first and second sensed parameters.

    摘要： A technique for operating a sensor system is provided. The method includes exciting a first sensor with a first excitation signal at a first frequency and exciting a second sensor with a second excitation signal at a second frequency. The technique also includes combining a first measurement signal generated from the first sensor with a second measurement signal generated from the second sensor to determine a sensed parameter. The technique may be employed for reducing crosstalk between closely proximate sensors, such as capacitive probes, and may serve to determine distances within operating machines, such as turbine systems.
