Abstract
A device for monitoring the activity of a person and/or detecting a fall suffered by a person with a view in particular to summoning help in the event of an incident hazardous to life or limb is worn by the person concerned and transmits a danger signal to a remote monitoring center. The device generates acceleration, speed and/or position signals representative of the behavior and/or the spatial attitude of the person. It establishes a probability factor representative of the probability that a dangerous situation is present from how the acceleration, speed and position signals change with time. It triggers in accordance with the value of the probability factor an alarm generator capable of causing the danger signal to be transmitted to the center.
