| 摘要 |
The invention concerns a method for discriminating signals generated by means sensitive to pressure variations of a gas fluid. This method is characterised in that, for discriminating electric signals, it operates as follows: when means (5) sensitive to pressure variations generates an electric signal, the evolution of the amplitude of at least one characteristic of this signal is monitored and, when two successive amplitude variations (A1, A2) substantially opposite relative to a median value are detected, means (6) for providing information to people are inhibited whereas when amplitude variations of a different type are detected, means (6) for providing information to people are activated.
