Secure area and sensitive material tracking and state monitoring

摘要

In one aspect, a system for monitoring an area containing sensitive material is provided. The system includes at least one radio frequency identification (RFID) tag for coupling to an object and a reading and warning system including an RFID tag reader operable to receive a signal from the at least one RFID tag. The reading and warning system provides a warning when the at least one RFID tag is coupled to the object and the RFID tag reader receives a signal from the at least one RFID tag, and the object is one of a sensitive material and a prohibited material.

主权项

1. A system for monitoring an area containing sensitive material, said system comprising:
an object comprising sensitive material, wherein said object is reactive to a predetermined condition, wherein subjection to the predetermined condition neutralizes said sensitive material; at least one radio frequency identification (RFID) tag coupled to said object and configured to change state when subjected to the predetermined condition; a reading and warning system comprising an RFID tag reader operable to receive a signal from said at least one RFID tag, wherein said reading and warning system provides a warning when said at least one RFID tag is coupled to said object and said RFID tag reader receives a signal from said at least one RFID tag, and wherein said reading and warning system is configured to determine when the object is neutralized based on at least one of: receiving an altered signal from said at least one RFID tag when said RFID tag changes state, or receiving no signal from said at least one RFID tag when said RFID tag changes state.
