1. A system comprising:
- a medical device of interest including a device component;
monitoring circuitry configured to measure operational data of the device component; and
a data processing system configured to output a report based at least in part on an analysis of the operational data of the device component, wherein the analysis of the operational data includes applying a wavelet transform to separate at least one signal component in the operational data, and predicting at least one of a failure rate or a survival rate of the device over a time period based at least in part on comparison of a coefficient characteristic of the wavelet transform to one or more threshold coefficient characteristics.

Abstract
A system and method to facilitate device monitoring and servicing is provided. In one embodiment, a system may include a medical device having at least one component, and monitoring circuitry configured to measure operational data of the component. The system can also include a data processing system configured to analyze the operational data and to output a report based on such analysis. The analysis, in turn, may include applying a transform to the operational data and comparing one or more actual coefficient and threshold coefficient characteristics.

6. A method comprising:
-
obtaining operational data of a device of interest, the operational data including a feature of interest; applying a transform to extract the feature of interest from the operational data; comparing a characteristic of a transform coefficient associated with the extracted feature of interest to a threshold derived at least in part from a statistical analysis of a population of additional devices similar to the device of interest; calculating an operating state of the device of interest dependent at least in part on the comparison; and outputting a report indicative of the operating state of the device. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
