Abstract

"PROCESSO PARA A DETECçãO REMOTA DE OBJETOS, SISTEMA PARA A DETECçãO REMOTA DE OBJETOS, PROCESSO PARA DETERMINAçãO DE UM COMPRIMENTO DE UM ELEMENTO MAGNéTICO ALONGADO, E, SENSOR PARA A DETECçãO REMOTA DE OBJETOS". é provido um processo para a detecção remota de objetos, onde um objeto individual (20) é provido com ao menos um sensor (30) compreendendo ao menos um elemento magnético (31-34) representando uma identidade do sensor. Um primeiro sinal eletromagnético (50) é gerado para a excitação do ou de cada elemento magnético para produzir um segundo sinal eletromagnético (60), uma amplitude do qual é modulada por um campo magnético (H~ mod~). Um sinal de resposta (80) é produzido pela demodulação do segundo sinal eletromagnético (60, 70). Uma variação em amplitude do sinal de resposta é detectado em resposta a uma variação em amplitude do campo magnético (H~ mod~), e a variação detectada em amplitude é usada para a determinação de uma propriedade geométrica, tal como o comprimento, do ou de cada elemento magnético (31-34). Uma identidade do sensor (30) é determinada a partir da propriedade genérica.
