An analysis andor measuring device includes means for extracting, in the gaseous form, hydrocarbons contained in a liquid fluid, means for transporting said extracted gases, and means intended for analysis and measurement on these extracted gases. A method may include receiving a short-range radio communication device information acquired by an SRC-enabled mobile terminal, authenticating the SRC device information, and allowing a mobile service to be provided to an SRC-enabled mobile terminal in response to the authenticating step. An off-chip regulator connected to the on-chip digital logic circuit provides an external core supply voltage with respect to the on-chip digital logic circuit.
