    Abstract: The sensor comprises a beam of electromagnetic radiation projecting across a gap between the stationary member and the translating member, a reference detector having a reference FOV and a signal detector having a signal FOV. The sensor is to be mounted on the stationary member. The electromagnetic radiation beam, the reference FOV and the signal FOV intersect in a volume including the gap, and the gap is calculated from the reflected electromagnetic radiation received by the reference and signal detectors. The gap can be determined from a ratio between a rise time in the signal pulse and a rise time in the reference pulse, or a ratio between a fall time in the signal pulse and a fall time in the reference pulse, or a ratio between a delay time in the signal pulse and a delay time in the reference pulse, among other features.

    Abstract: Optical fiber preforms which can be drawn into optical fibers of desired dimensions are fabricated by applying a vacuum to a cladding tube and drawing molten glass from a crucible into a bore of the cladding tube while a portion of the cladding tube is within a furnace preferably through a small hole in the top of the furnace. The method and apparatus are particularly applicable to highly non-linear fiber (HNLF) glasses and highly doped or rare earth glasses since materials therein are generally expensive and only a small quantity of molten glass is required but can be applied to virtually any optical fiber construction where the core glass has a lower melting or softening point than that of the cladding tube. Sources of contamination, breakage and other preform defects are substantially avoided and toxic substances, if present are readily confined.

    Abstract: The present invention relates to systems and methods for real-time health monitoring of engines to monitor turbomachinery blades during engine operation and report anomalous behavior and shape of the blades if it occurs, such as damage by FOD. The system comprises sensor(s) for obtaining a blade reflection profile from a blade passing by the sensor(s) during a revolution of the rotor in combination with a processor for performing timing calculations and/or fingerprint comparisons with reference data to identify a change in blade fingerprint relative to the reference data, which may indicate blade damage. Such systems can reduce operational costs, enhance safety and improve operational readiness by facilitating condition-based maintenance of engine rotors as opposed to schedule-based solutions. The invention can prevent the needless loss of life and assets caused by undetected minor levels of blade damage that may lead to unexpected catastrophic failure of an engine.

    Abstract: An apparatus and a method for ascertaining a gap between a stationary member and a rotating member are disclosed. At least a reference beam and a signal beam, which have different focal lengths or which diverge/converge at different rates, are fixed to the stationary member and proximate to each other. The beams are projected across a gap between the stationary member and the rotating member toward the rotating member. The reference and signal beams are reflected by the translating member when it intersects the reference and signal beam, and the reflected reference and signal pulses are obtained. One or more features of the reflected reference pulse and the reflected signal pulse, such as a rise time of the pulses, a fall time of the pulses, a width of the pulses and a delay between the reflected reference pulse and the reflected signal pulse, among other factors, are obtained. The width of the gap is obtained using at least one of these factors.
