US 2021/0264757 A1 · EAS DEVICE WITH ELASTIC BAND

Abstract

An electronic article surveillance (EAS) device for monitoring items comprises an electronics housing and an elastic band. The band is attached to the housing and is used to install the EAS device onto an item. A tension monitoring apparatus monitors the band and generates a signal based on the band's state of tension. Electronics within the housing receive this signal and use it to determine the status of the EAS device, i.e. installed, armed, tampered with, etc. Loss of tension may indicate a cut band or removed EAS device. Other sensors may also generate inputs for the electronics to evaluate. These include an installation sensor to monitor contact between the housing and an item and an arming switch to arm the EAS device before installation. The EAS device may have wireless communication capabilities, and external devices may arm and disarm the device with wireless communication.

Dependent claims

An electronic article surveillance (EAS) device comprising:

a housing having a first aperture through it;
a band having a first end anchored to the housing and a second end inserted into the housing through the first aperture, the second end being anchored within the housing;
a cantilevered lever arm extended between the first aperture in the housing and the second end of the band, wherein when sufficient tension is induced in the band, the band displaces the cantilevered lever arm;
a first sensor in the housing, the first sensor monitoring the position of the cantilevered lever arm and communicating the position of the cantilevered lever arm;
and,
electronics within the housing, the electronics interpreting the communication from the first sensor to determine if an alarm condition exists.

3 more elements

An electronic article surveillance (EAS) device comprising:

a housing enclosing an interior space and having a first aperture through it;
a band having a first end fixed with respect to the housing and a second end inserted through the first aperture into the interior space and attached therein;
a tension monitoring apparatus within the interior space of the housing, the tension monitoring apparatus monitoring whether the band is under tension and generating a signal indicating the tension status of the band;
and,
circuitry within the interior space configured to monitor the signal from the tension monitoring apparatus and to determine when an alarm condition exists.
