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.
