20110267620 | ARC FLASH DETECTION SYSTEM AND METHOD - A sensor to simultaneously detect light and acoustic waves is presented. The sensor includes one or more optical fibers and a diaphragm disposed near one end of at least one of the one or more optical fibers. The diaphragm is configured to vibrate upon incidence of acoustic waves from an arc flash and reflect a light beam into at least the one of the one or more of the optical fibers. A semi-transparent region is disposed around the one or more optical fibers to diffuse light originating from the arc flash into at least one of the one or more optical fibers. | 11-03-2011 |
20120002195 | ARC FLASH DETECTION METHOD - An arc flash detection method includes transmitting light via an optical fiber to a sensor and transmitting light from the sensor that includes components representative of acoustic waves and light for filtering and processing to detect an occurrence of an arc flash. | 01-05-2012 |
20120045330 | SYSTEM AND METHOD FOR MONITORING AND CONTROLLING PHYSICAL STRUCTURES - A system for controlling a wind turbine is disclosed. A system includes a light source and a beam scanner to scan the light pulses over the wind turbine. The system further receives backscattered light pulses and subsequently, provides a signal corresponding to the light pulses. The system adjusts a threshold of the signal based on a normalized value of a detected peak value of the signal. The system associates a time of flight with each of the received backscattered light pulse. The system generates an image of the wind turbine based on the time of flight associated with the light pulses and subsequently, compares the generated image with at least one known image of the wind turbine. The system generates a health profile of the wind turbine based on the comparison and subsequently, change one or more parameters of the wind turbine based on the health profile. | 02-23-2012 |
