<p>A method for monitoring a biological parameter out of either the heartbeat and/or respiratory signal of an occupant (2) on a member of a seat or bed. The member supports at least one sensor (6) capable of detecting variation of pressure due to contact, and at least one accelerometer is connected to the member. A model of a transfer function between at least one signal from one accelerometer out of either the accelerometer and/or at least one accelerometer at the input and a signal from a sensor (6) out of either the sensor and/or a plurality of sensors at the output is made, a noise value is estimated using this model, and the estimated noise value is removed from the signal from the sensor (6).</p> |
