The method comprises the steps: monitoring at least one aspect of the behavior of the person (S1); analyzing whether the monitored behavior of the person corresponds to an expected behavior for a state of full consciousness or not (S2, S2?); triggering an alarm if the analysis results in that the detected behavior does not correspond to the expected behavior (S3).

Abstract: In summary, the present invention relates to a device, a method, a system and a computer program enabling to ensure a reliable communication even under difficult radio frequency conditions. In case data cannot be successfully communicated by a radio frequency communication, the data may be transmitted to another device by a body-coupled communication via a human or animal body. The other device can act as a relay and forward the data to an intended destination. Thus, data may be successfully transmitted to the intended destination even under difficult radio frequency conditions due to body shadowing or other effects.
