Abstract: A method for monitoring the operation of a component includes receiving a stream of data samples, wherein each data sample represents a value of a physical parameter of the component, identifying local extrema of the stream of data samples, storing information relating to each local extremum in a respective position of a fixed size buffer, and upon the presence of a cycle formed between two matching endpoints represented by two local maxima or two local minima: i) deleting at least one of the local extrema corresponding to the endpoints of the cycle from the buffer, and ii) storing information related to the cycle in a memory such that the information stored in the memory represents the operation of the component. When the buffer is full such that each position of the buffer contains information relating to a unique local extrema, the method further includes the steps of i) deleting the information relating to the oldest local extrema from the buffer, ii) calculating a pseudo cycle formed between two endpoints of which one endpoint is represented by the deleted oldest local extrema, and iii) storing information related to the calculated pseudo cycle in the memory.

Abstract: A method for monitoring the operation of a sensor is provided. The method comprises the step of representing the operation of the sensor by: i) storing a plurality of data values, each data value corresponding to the sensor output signal, wherein said step is performed during a time period such that said data values are distributed over a range of possible data values, ii) defining a plurality of discrete intervals within said range of possible data values; and iii) calculating the frequency of the data values within each interval thus forming a sensor representation. The method further comprises the steps of receiving at least one reference sensor representation; and comparing said sensor representation with said at least one reference sensor representation.
