Abstract

"DISPOSITIVO DE DESATIVAçãO DE MARCADOR EAS TENDO BOBINAS ENERGIZADAS ENROLADAS EM NúCLEO". Um dispositivo (50) para desativar um marcador EAS magnetomecânico inclui uma bobina (64,66,68,70) e um conjunto de circuitos (72) para energizar a bobina para gerar um campo magnético alternado. A bobina é enrolada em torno de um núcleo magnético (52) . o núcleo pode ser cruciforme com quatro braços, em cada um dos quais uma respectiva bobina é proporcionada. Alternativamente, o núcleo pode ser geralmente quadrado e plano, com as duas bobinas (102, 104) enroladas em torno do núcleo (100) nas diferentes direções respectivas.
