1. An apparatus to determine a body temperature from a carotid artery source point, the apparatus comprising:

  • a housing;

    a non-contact electromagnetic sensor operably mounted to the housing, the non-contact electromagnetic sensor being operable to receive electromagnetic energy from the carotid artery source point of a subject and operable to generate a numerical representation of the electromagnetic energy of the carotid artery source point;

    a printed circuit board mounted in the housing, electrically coupled to the non-contact electromagnetic sensor and operable to determine the body temperature of the subject from the numerical representation of the electromagnetic energy of the carotid artery source point,wherein determining the body temperature of the subject further comprises;

    calculating the body temperature as fstb(Tsurface temp+fntc(Tntc))+F4body,where fstb is a representation of a surface of the body,where Tsurface temp is the numerical representation of the electromagnetic energy of the carotid source point,where fntc is mathematical formula of an ambient temperature reading,where Tntc is the ambient air temperature reading,where F4body is the representation of the calibration difference,fntc(Tntc) is the bias in consideration of the temperature sensing mode; and

    a button operably coupled to the printed circuit board.
