  1. 감시영역(surveilance zone)내에서 진동전자 검색계(oscillating electromagnetic interrogation field)를 발생하기 위한 수단, 레이블의 공각적인 방위에 관계없이 상기 전자검색계를 통과하는 사이에 상기 발생된 전자계를 커트 혹은 연결하도록 고안되어 물체에 부착된 레이블로 이루러짐으로써 경보를 발하도록 하는 회로수단을 포함한 수신수단에 포착된 신호를 발생시키는 것을 특징으로 하는 감시영역을 지나는 물체의 통과를 검출하기 위한 도난방지시스템 (antishoplifting system)의 개량 장치.
  2. 제1항에 있어서, 신호의 왜곡을 최소로하는 전자회로수단을 갖춘 것을 특징으로 하는 장치.
  3. 제2항에 있어서 레이블 신호를 다른 신호로부터 구별하는 전자회로수단을 갖춘 것을 특징으로 하는 장치.
  4. 제3항에 있어서, 최대투자을(permeability) 1000,000과 보자력 0,05 Oe를 갖는 레이블을 갖춘 것을 특징으로 하는 장치.
  5. 검색영역에 위치할때 신호를 발할 수 있는 레이블을 물체에 부착시킴으로써 그 신호가 경보를 발할 수 있도록 고안된 전자회로수단을 포함한 수신수단에 의해 포착되는 것을 특징으로 하는 진동전자계를 가진검색영역에 물체가 존재할 때 그 물체의 존재를 검출하기 위한 도난 방지 시스템의 개량방법.
  6. 제5항에 있어서, 레이블이 12,5KHz의 기본주파수를 갖는 진동전자계에 의해 여자되었을때 상기 레이블에 의해 발생된 최상의 검출 가능한 신호는 대략 160번째 고조파 혹은 2KHz가 될 이러한 저고조파의 신호를 발생시키는 레이블을 갖춘 것을 특징으로 하는 방법.
