IDENTIFYING A TEMPERATURE ANOMALY

摘要

A device comprising: a communications interface configured to receive one or more first signals each indicating a respective temperature level sensed by a respective first temperature sensor located above a surface, and to receive one or more second signals each indicating a respective temperature level sensed by a respective second temperature sensor located below said surface; and detection logic configured to compare the one or more first 5 signals with the one or more second signals to identify a temperature anomaly above or below said surface, and thereby generate an output indicative of said temperature anomaly.
