METHODS, SYSTEMS AND DEVICES FOR ELECTRONIC ARTICLE SURVEILLANCE DEACTIVATION HAVING RANDOMIZED TRANSMISSION RATES

摘要

Methods, systems and devices for providing an interrogation signal from a handheld deactivation device for identifying a security tag. Identifying the security tag includes initiating an interrogation signal, wherein the interrogation signal includes plurality of transmission bursts and a plurality of random time periods to wait between transmission bursts such that a unique time period elapses between each of the plurality of transmission bursts. The interrogation signal is then transmitted by transmitting each of the plurality of transmission bursts for a portion of a duty cycle and interrupting transmission between each of the plurality of transmission bursts for one of the plurality of random time periods such that a unique and random time period elapses between each of the plurality of transmission bursts. The period transmission of the interrogation signal provides for improved battery life of a handheld scanning and deactivation device.

1. A method for providing an interrogation signal from a handheld deactivation device for identifying a security tag, the method comprising:
initiating, by a processing device, an interrogation signal, wherein the interrogation signal comprises a plurality of transmission bursts and a plurality of random time periods to wait between transmission bursts such that a unique time period elapses between each of the plurality of transmission bursts; and transmitting, by a transmit module operably connected to the processing device, the interrogation signal.
