Abstract

"PLACA DE IDENTIFICAçãO E MéTODO PARA A DETECçãO DA MESA". Método para detectar um artigo de placa de identificação (30), que tem pelo menos um membro eletricamente condutor (31-3n). Para cada membro eletricamente condutor, faz-se com que uma corrente elétrica alternada flua através do membro. A freq³ência da corrente elétrica alternada é variada, e uma variação correspondente na impedância do membro é monitorada. Uma descontinuidade na variação da impedância é detectada, e a freq³ência da corrente elétrica alternada é detectada, isto é, a freq³ência em que a descontinuidade aparece."IDENTIFICATION PLATE AND METHOD FOR DETECTING THE TABLE". Method for detecting a nameplate article (30), which has at least one electrically conductive member (31-3n). For each electrically conductive member, an alternating electric current is caused to flow through the member. The frequency of the alternating electrical current is varied, and a corresponding variation in limb impedance is monitored. A discontinuity in the impedance variation is detected, and the frequency of the alternating electric current is detected, that is, the frequency at which the discontinuity appears.
