Abstract: A method of obtaining a feature for blood pressure estimation is provided. The method includes extracting a reference feature from a bio-signal; obtaining a feature for blood pressure estimation by: obtaining, as the feature for blood pressure estimation, a first candidate feature based on the reference feature being less than a first threshold; obtaining, as the feature for blood pressure estimation, a second candidate feature based on the reference feature being greater than or equal to a second threshold that is greater than the first threshold; or obtaining, as the feature for blood pressure estimation, a combination of the first candidate feature and the second candidate feature based on the reference feature being less than the second threshold; and estimating a blood pressure by using the obtained feature.

Abstract: There is provided an apparatus (12) for use in measuring blood pressure. The apparatus (12) comprises a processor (102) configured to acquire a signal indicative of pressure oscillations detected inside a cuff inflated to pressurize a measurement site of a subject undergoing cardiopulmonary resuscitation. The pressure oscillations detected inside the cuff are indicative of a pulse of the subject. The processor (102) is also configured to trigger a blood pressure measurement for the subject based on the pressure oscillations detected inside the cuff.

Abstract: An apparatus for estimating a core body temperature of an object is provided. The apparatus may include a heat flow sensor configured to measure a first heat flux from an object, a first temperature sensor positioned under a thermal conducting material and configured to measure a surface temperature of the object, a second temperature sensor positioned above the thermal conducting material and configured to measure a surface temperature of the thermal conducting material, and a processor configured to obtain a second heat flux by calibrating the first heat flux based on the surface temperature of the object and the surface temperature of the thermal conducting material, and configured to estimate a core body temperature of the object based on the obtained second heat flux and the surface temperature of the object.
