Abstract: An indicator generating method for generating an indicator which is suitable for maintenance prediction of a water heating system is proposed. A power state indication device generates a high power consumption signal if a heating device of the water heating system is activated. The time duration of the activation is such an indicator, if no water flow is present. Furthermore, the time interval between subsequent activations is such an indicator. A predictive maintenance method processes these condition-based indicators and determines a remaining useful lifetime according to a predictive maintenance model. The predictive maintenance device outputs a maintenance signal indicating required maintenance, if the remaining useful lifetime drops below a predetermined threshold. The methods may be performed by water heating systems or beverage makers.

Abstract: A data acquisition system, particularly for use in avionics systems, has a control and monitoring apparatus having a plurality of electronic application components and a multiplexer coupled to the plurality of electronic application components, a domain network interface coupled to the multiplexer, a data collection component having a data flow controller and a data collection memory component coupled to the data flow controller, a plurality of external interfaces, and an interface component implemented in the data collection component and coupled between the data flow controller and the plurality of external interfaces. The interface component is configured to allow bidirectional protocol-based communication between the data flow controller and systems connected to the plurality of external interfaces.
