Abstract: A method for monitoring the operating conditions of an electric generator for mechanical strain and temperature includes means of distributive fiber optic sensors based on both Rayleigh back scattering techniques and Brillouin frequency shift fiber optic sensor analysis as both Rayleigh and Brillouin scans and allow accurate strain and temperature determinations at all points along standard fiber optic cables of considerable length, which effectively yields thousands of sensors throughout the entire standard fiber optic cable. Raman distributive temperature sensing also has a limited application. Single mode and polarizing maintaining fibers can both be analyzed and read with any Rayleigh or Brillouin distributive fiber optic sensor laser system allowing great flexibility in sensor spatial resolution, total sensed length, resolution and other factors.

Abstract: A temperature sensor is disclosed. The sensor includes an optical fiber and at least one twin-grating structure formed on the optical fiber. Each twin-grating structure includes a first optical grating structure, a second optical grating structure adjacent the first optical grating structure, and a sensing cavity disposed between the first and second optical grating structures. Each twin-grating structure is selectively responsive to a unique wavelength of light to generate an optical interference fringe signal. For each twin-grating structure, an optical property of the twin-grating structure and a phase of the optical interference fringe signal generated by the twin-grating structure are determined by a temperature of the twin-grating structure.

Abstract: The present invention is directed to improving the accuracy with which a stationary array sensor provides cross directional measurements by providing an offset compensation to the stationary array sensor using the output of a scanning sensor associated with the manufacturing process. Exemplary embodiments correlate outputs from the stationary sensor array and the scanning array using a data reconciliation process. For example, a practical, real time data reconciliation of measurements from the scanning sensor and measurements from the stationary array sensor is achieved by computing offsets using a bank of Kalman filters to correlate outputs from the two sensors for each measurement zone, wherein each filter possesses a relatively simple computational structure. The Kalman filters can fuse the outputs from the stationary array sensor and the scanning sensor to track, and compensate, drift of the stationary array sensor.

Abstract: A method and apparatus for controlling fraction collection in an eluent stream flowing from an LC column. A triggering detector recognizes the presence of a target substance according to characteristics of chromatographic peaks in the eluent stream and initiates a delay timer to trigger the fraction collector. A waste stream detector is disposed at any distance from the fraction collector to detect peaks in the waste stream flowing from a fraction collector. The signature of fraction collector actuation is seen by the waste stream detector, permitting the delay time to be adjusted for optimal collection of the target compound. The presence or absence of a peak or the characteristics of a remnant peak detected by the waste stream detector are used to confirm that the target component of the eluent stream was collected as intended by the fraction collector.
