    Abstract: A method is provided of creating a 3D temperature map of a component. The method includes the steps of: (a) providing plural shape models of the component corresponding to respective camera views of a 3D CAD model of the component; (b) providing plural images of the component captured after a thermal paint test, each image being a view of the component corresponding to a respective one of the shape models; (c) extracting data from each image by performing the sub-steps of: (c-i) adjusting the position and/or orientation of each shape model so that the camera view of the CAD model provided by that shape model matches the view of the component provided by the corresponding image, and (c-ii) identifying temperature bands within the images and encoding the temperature bands within the matched, corresponding shape models; and (d) forming a 3D temperature map of the component from the encoded temperature bands.

    Abstract: An apparatus for calculating an angular speed of a rotary component includes a processor circuitry configured to: receive an in-phase signal and a quadrature signal from a sensor arrangement, each signal relating to a position of the rotary component; arithmetically sum the in-phase signal and the quadrature signal generated by the sensor arrangement to produce a combined time-domain signal; and calculate an angular speed of the rotary component based on the combined time-domain signal. Methods of calculating an angular speed of a rotary component are also provided.

    Abstract: An apparatus for detecting a transient event in an operating machine, the apparatus comprising: a controller configured to control performance of the following steps: a measurement step comprising measuring a periodic signal from a machine; a processing step comprising synchronously processing the periodic signal to track the primary frequency; a filtering step comprising removing the primary periodic component and its harmonics from the periodic signal to yield a filtered dataset; an integration step comprising integrating the filtered dataset over the remaining frequencies to yield an integrated dataset representing the periodic energy at frequencies other than the primary frequency and its harmonics; an analysis step comprising identifying a short-term transient in the integrated dataset to identify a transient disruption in the operation of the machine.
