Abstract:
A breakaway RFID tag is configured such that it comprises part of a Printed Circuit Board Assembly (PCB). Thus, the breakaway RFID tag can be used to track the PCB as it migrates through a manufacturing process. In one embodiment, the RFID tag can be assembled first and then used to track the PCB as it is populated with components and installed into larger assemblies and ultimately into the end device. Once the PCB is installed into a larger assembly or the end device, the breakaway RFID tag is configured such that it can be broken off and attached to the outside of the larger assembly or end device.

Abstract:
RFID tags are used for many purpose including tracking. RFID interrogators are used to retrieve information from tags. In many applications, a plurality of RFID interrogators are required. Synchronization between interrogators in the same theater of operation is critical to ensure that their broadcasts do not interfere with each other. In fixed RFID interrogator applications, RFID interrogators can be wired together allowing a channel to synchronize the transmissions of the RFID interrogators. Methods described herein can ensure that synchronization is maintained in the event of the failure of a synchronizing master. Furthermore, additional methods for synchronizing RFID interrogators in wireless applications are described allowing synchronization in the absence of wired connections between interrogators.
