1. A system to determine a state of a presentation device, the system comprising:
evaluating means for determining contribution values from at least one of a signal measured from a sensing device or an output signal accessed from the presentation device, the contribution values indicative of a state of a presentation device;
analyzing means for summing a first plurality of the contribution values corresponding to a first measurement cycle to generate a first intermediate fuzzy score for the first measurement cycle;
storing means for storing the first intermediate fuzzy score with a plurality of intermediate fuzzy scores corresponding to respective measurement cycles, the analyzing means to combine the intermediate fuzzy scores for a first time period to form a final fuzzy score; and
crediting means for crediting the state of the presentation device as on when the final fuzzy score satisfies a first threshold.
