Abstract: Systems and techniques to facilitate generating and/or encoding rotational data associated with a mechanical element are presented. A sensor system can measure rotational speed data and phase data associated with a mechanical element that rotates. The sensor system can also encode the rotational speed data and phase data into a digital data packet. Furthermore, the sensor system can transmit the digital data packet associated with the rotational speed data and phase data to one or more sensor devices in communication with the sensor system.

Abstract: A method of component monitoring for machinery having multiple rotating elements, which are rotated at different rotational speeds, the method including sampling data from the vibration sensor at a sampling frequency at least as great as the fastest rotational speed of the multiple rotating elements to form a data set and determining an actual rotational frequency for at least some of the rotating elements during the sampling of the data.

Abstract: Systems and methods for determining aircraft component phase position are provided. In one embodiment, a method can include receiving a set of data from a data acquisition system associated with a component. The method can include identifying a plurality of phase reference points based, at least in part, on the set of data. Each phase reference point can be indicative of a phase position of the component relative to the data acquisition system at a respective point in time. The method can include generating a model based, at least in part, on the plurality of phase reference points. The model can be indicative of the phase position of the component relative to the data acquisition system at a plurality of times. The method can include determining the phase position of the component at one or more points in time based, at least in part, on the model.
