    Abstract: A system for optically monitoring a gas turbine engine includes a viewport into the gas turbine engine, and an optical connection having a first axial end and a second axial end. The first axial end is optically coupled to the viewport and configured to receive an image from the viewport, the optical connection includes a substrate having multiple hollow passages each extending from the first axial end to the second axial end, and each hollow passage includes a reflective coating disposed on an inner surface of the hollow passage to facilitate transmission of a respective portion of the image from the first axial end to the second axial end. In addition, the system includes a detector array in optical communication with the second axial end of the optical connection. The detector array includes multiple detection elements configured to receive multiple respective portions of the image from the hollow passages.

    Abstract: A method for generating a sampled plethysmograph data, includes measuring a plethysmograph waveform indicative of a first cardiac cycle and a second cardiac cycle, each cycle including a systolic waveform and a diastolic waveform. The method further includes estimating a first start time and a first duration for the systolic waveform of the first cardiac cycle and computing a plurality of amplitudes at a plurality of time instants for the first duration. The method further includes determining a second start time and a second duration of the systolic waveform of the second cardiac cycle. The method also includes assigning the second cardiac cycle, the second start time, and the second duration to the first cardiac cycle, the first start time, and the first duration respectively. The method further includes iteratively performing the steps of measuring, estimating, computing, determining and assigning for the plurality of cardiac cycles acquired sequentially in time.

    Abstract: A system for optically monitoring a gas turbine engine includes a viewport having an opening disposed within a casing of the gas turbine engine. The opening extends from an interior side of the casing to an exterior side of the casing, and the viewport is configured to receive an image from inside the casing. The system also includes an optical connection positioned outside the casing and optically coupled to the viewport. The optical connection is configured to convey the image from the viewport to a detector array, and the optical connection includes multiple optical fibers fused to one another to form a unitary substantially rigid fiber bundle.

    Abstract: A system and method including receiving a data model representation of a part, the data model representation including at least one layer of the part and inner and outer contours for the at least one layer; determining a hatch pattern for each layer of the at least one layer of the part, the hatch pattern for each layer being dependent on the inner and outer contours for each respective layer; generating a record of the determined hatch pattern for each layer, the record including locations for the hatch pattern for each layer; and saving the record of the determined hatch pattern for each layer of the part. In some aspects, the record of the determined hatch pattern for each layer of the part may be used in an additive manufacturing process.
