Patent ID: 11162750

Abstract:
A system and method for detecting the presence of firearms adapted with embedded RFID tags is disclosed. A plurality of RFID interrogators sequentially and intermittently transmit short burst interrogating signals thereby causing RFID tags within range to transmit a responsive signal which may be used to activate alarms and other security measures. RFID tags are configured using an ASIC chip enabled for 10 Ghz wireless communication. The ASIC chip is embedded within a bolt carrier that includes a slotted antenna aperture resulting in extended range wireless communication. A plurality of RFID interrogators are installed in an detection area and transmit a radio frequency signals which excite any RFID enabled devices within range causing the devices to generate and transmit a response signal which may be used to trigger a variety of security measures such as sounding an alarm, locking doors, contacting law enforcement, etc.
