Wireless tracking system and method with extreme temperature resistant tag
A wireless tracking system and method for real-time location tracking of an extreme-temperature sterilizable object is disclosed herein. The system and method utilize a tag attached to the extreme-temperature sterilizable object which includes a housing, a processor, a temperature sensor and a transceiver. If an internal temperature of the tag is detected by the temperature sensor, the tag enters a sleep mode. The temperature sensor periodically activates to determine if the internal temperature of the tag is within an acceptable operating range.
1. A method for real-time location monitoring of a sterilizable object subjectable to abnormal temperature during a sterilization process, the method comprising:
tracking a location of a sterilizable object bearing an RFID tag;
detecting an internal temperature of the tag exceeding an acceptable operating temperature range for the tag, the acceptable operating temperature for the tag ranging from 40° F. to 120° F.;
activating a sleep mode for the tag responsive to said detecting;
determining an internal temperature of the tag within the operating range for the tag; and
reactivating an operating mode for the tag responsive to said determining.
