Abstract
Methods and apparatuses () for detecting body-related temperature changes are provided. The method comprises measuring a skin-surface temperature at a first temperature sensor element () at a measuring rate (S) and measuring an ambient temperature at a second temperature sensor element () at the measuring rate (S). The method also comprises calculating a plurality of first change rates for the skin-surface temperature and a plurality of second change rates for the ambient temperature over a time interval (S). The method further comprises determining, based on the plurality of first change rates and the plurality of second change rates, whether an ambient temperature change rate is faster than a skin-surface temperature change rate by a threshold (S). The method additionally comprises selecting whether or not to trigger an alarm based on a result of the determining (S). With the methods and apparatuses (), the number of false alarms may be significantly reduced.
