  • Patent number: 5499015
    Abstract: An inventory of goods is protected from theft by means of electronic article surveillance (EAS) markers integrated with items of the inventory. Each such item has a structural member in which a cavity is integrally formed. A respective magnetostrictive element is housed, free of mechanically clamping constraint, in each cavity. A respective biasing element is located adjacent to the cavity on each such item of inventory. The biasing element provides a magnetic field to bias the respective magnetostrictive element. EAS equipment is provided at a retail store where the inventory is maintained. The EAS equipment generates an alternating electromagnetic interrogation field, and when an item of inventory having the integrated EAS marker is exposed to the interrogation field, the biased magnetostrictive element is excited into mechanical resonance that is detected by the EAS equipment.
