Electronic anti-theft protection system

摘要

The invention relates to an electronic system for anti-theft protection of goods. The system comprises: a unit for detecting a metallic material in a first detection zone; a unit for detecting a magnetic or magnetizable material in a second detection zone; and a control unit. The control unit is capable of receiving information from the units for detecting metallic and magnetic material when the one or both of these units detect(s) a metallic or a magnetic material, respectively, in the respective detection zones. The control unit is further programmable to the effect that the control unit can be programmed to emit a signal which depends on whether it receives information about the detection of metallic and/or magnetic material.

1. An electronic system for anti-theft protection of goods, said system comprising:
a unit for detecting a metallic material in a first detection zone; a unit for detecting a magnetic or magnetisable material in a second detection zone; and a control unit,wherein the control unit is configured to receive information from the units for detecting metallic and magnetic material when the one or both of these units detect a metallic or a magnetic material, respectively, in the respective detection zones, and is programmable to cause the control unit to emit a signal indicative of whether the control unit receives information about the detection of metallic and magnetic material, and whether the control unit receives information about the detection of a metallic material, while simultaneously not receiving information about the detection of magnetic materials, wherein the unit is configured to determine a position of a material that is both metallic and magnetic, wherein when the material is detected at a first position, the control unit does not emit the alarm and when the material is detected at a second position, the control unit emits the alarm.
