Abstract:
1. A sensor device for determining a particle impact center area, said sensor device comprising M sensing areas, at least one impact causing a variation of at least one physical magnitude of several sensing areas, said sensor device further comprising: means for determining an impact center area for each set among a plurality of possible sets of n sensing areas including the impact center area and other sensing areas neighboring said impact center area, where n is at least 2 and strictly less than M; a circuit adapted to determine whether an impact occurred in this set; a circuit for summing the physical magnitude variations of the set of n sensing areas and providing a result; a circuit for selecting a first set of sensing areas, by comparing the results corresponding to the possible sets and determining the first set, as the one for which the result of the sum of the physical magnitudes is maximal; said circuit (WTA) further being for allocating to said impact center area the result corresponding to said first set.
