Abstract

"DETETOR PARA SENTIR A PRESENçA DE UMA ETIQUETA MAGNéTICA E LEITORA DE NOTA BANCáRIA", tendo um eixo de fácil magnetização, que compreende (1) sejam (i) um imã ou (ii) um par de imãs disposto em oposição magnética, o imã ou os imãs estando dispostos de modo a definir uma região espacial através de ou em que a etiqueta magnética é, em uso, passada; a disposição de dito(s) imã(s) e o modelo de campo magnético resultante sendo tais que provoca uma alteração na polaridade da magnetização de dita etiqueta magnética durante sua passagem através de um nulo magnético dentro de dita região espacial; e (2) uma bobinha ou bobinas do receptor, posicionadas acima e em proximidade de um polo de dito imã (onde é empregado apenas um imã) ou posicionadas entre dito par de imãs (onde são empregados dois imãs) e dispostos para detectar a radiação do dipolo magnético emitida por etiqueta magnética ao passar através de dito nulo magnético, estando o eixo fácil de magnetização da etiqueta orientada na direção do deslocamento. As bobinas do receptor são cosntruídas preferivelmente como um conjunto de circuitos impressos, cujas trilhas condutivas estão interligadas para formar uma bobina tridimensional tendo enrolamentos nas várias camadas.
