Abstract:
1. A system for determining a fault threshold for an operational module, the system comprising: a storage unit maintaining a mapping of parameter values to fault thresholds for different production models of operational modules, each parameter value mapping to a fault threshold for one of the different production models; an operational module of a particular production model having circuitry for producing a characterization signal with an electrical characteristic from which a parameter value may be derived, the circuitry being configured such that the parameter value derived from the electrical characteristic maps uniquely, in accordance with the mapping maintained by the storage unit, to the particular production model of the operational module and distinguishes the particular production model of the operational module from other production models of the operational module; and a monitoring unit in communication with the operational module to receive the characterization signal and with the storage unit, the monitoring unit measuring the electrical characteristic of the characterization signal to derive the parameter value therefrom and accessing the mapping maintained by the storage unit to obtain therefrom the fault threshold to which the derived parameter value maps, thereby obtaining the fault threshold for the operational module.
