Abstract:
Techniques for monitoring temperature inside refrigerators or heaters and tracking people and/or objects, particularly within a medical setting. For temperature monitoring, temperature readings are obtained using a temperature monitor. The temperature readings are transmitted from a radio frequency identification (RFID) tag to an RFID reader. The temperature readings received by the RFID reader are then monitored as a function of time. For tracking people or objects, RFID tags are attached to the people or objects, a facility is equipped with one or more RFID readers, and activity of the people or objects is monitored.
