20100242619 | SYSTEM AND METHOD FOR PREVENTING STRAIN CAUSED ERRORS IN FIBER OPTIC SENSORS - An encapsulated fiber Bragg grating sensor is provided wherein the EFL of sensor as well as the coefficient of friction between the sensor and the encapsulating tubing is controlled to minimize measurement errors caused by tensile and compressive strains. A method of manufacturing such a sensor is also provided. | 09-30-2010 |
20100172383 | Multivariable control system with state feedback - A system and method for controlling the output of a semiconductor laser is presented. The system and method includes using non-linear equations to calculate a state space model of the laser around an operating point. Adaptive algorithms are calculated and control signals determined using a controller to determine appropriate control laws and cost functions, which are then optimized and used to feed back a control signal to the semiconductor laser to improve the performance and stabilize the output of the laser. | 07-08-2010 |
20090220187 | RUGGED FIBER OPTIC TOWED ARRAY - A fiber optic towed array is provided. The array includes a flexible core upon which is disposed a semi-rigid mandrel. The semi-rigid mandrel has a helical groove formed therein, in which is disposed an optical fiber, the optical fiber including a plurality of fiber gratings. The mandrel is in turn covered with a nylon or fiber screen and encased in a layer of open cell foam, which is encased in a protective covering that includes at least one strength member disposed along a longitudinal axis of the array. | 09-03-2009 |
20090211768 | SYSTEM AND METHOD FOR DEPLOYING OPTICAL FIBER IN A WELL - A system and method for deploying an optical fiber within the bore or a well using a linear traction to push the optical fiber, typically encased in a protective sheath, down an instrumentation tube to place an optical fiber sensor at a desired location with the bore of the well. | 08-27-2009 |
20090211699 | NOVEL METHOD TO AFFIX AN OPTICAL ELEMENT - A method for affixing an adjustable optical element in place to allow for tuning an optical device during assembly of the device, but which provides for fixation of the element in place after adjustment. | 08-27-2009 |
20090092351 | HIGH DENSITY FIBER OPTIC ACOUSTIC ARRAY - A method for optimizing the architecture of a linear sensor array using WDM-TDM technology and stabilizing the reflectivity spectral profile of the fiber Bragg gratings of the sensors against the influence of environmental factors such as pressure and temperature is provided. The method includes stripping a portion of the foamed coating on the exterior of an optical fiber in the region of the fiber Bragg grating to thin the coating in the region of the grating. After the coating is stripped and the optical fiber cleaned, the area of stripped fiber is recoated with an unvoided plastic. | 04-09-2009 |
