Abstract

"DISPOSITIVO SENSìVEL AO CONTATO". A presente refere-se a um dispositivo sensível ao contato que compreende um membro (12) capaz de suportar as ondas de flexão, três sensores (16) montados sobre o membro (12) para medir a vibração de onda de flexão no membro, por meio de que cada sensor (16) determina um sinal de onda de flexão medido e um processador o qual calcula um local de um contato sobre o membro dos sinais de onda de flexão medidos. O processador calcula um ângulo de fase para cada sinal de onda de flexão medido e uma diferença de fase entre os ângulos de fase de pelo menos dois pares de sensores de modo que pelo menos duas diferenças de fase são calculadas das quais o local do contato é determinado."CONTACT SENSITIVE DEVICE". The present invention relates to a contact sensitive device comprising a member (12) capable of supporting flexural waves, three sensors (16) mounted on the member (12) for measuring flexural wave vibration in the member, for example. whereby each sensor (16) determines a measured bending wave signal and a processor which calculates a location of a contact on the member of the measured bending wave signals. The processor calculates a phase angle for each measured bending wave signal and a phase difference between the phase angles of at least two pairs of sensors so that at least two phase differences are calculated from which the contact location is. determined.
