  • Patent number: 10296674
    Abstract: A method for providing a model for a part of a vehicle includes selecting at least one operation state, selecting at least one possible fault type for the vehicle part, simulating vehicle part performance for the at least one operation state during the occurrence of the at least one possible fault type, for each simulation creating a representation of the vehicle part performance in which each representation is associated with at least one operating parameter value, and storing the at least one representation.
    Type: Grant

  • Patent number: 10198334
    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.

  • Patent number: 10109118
    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.
