Non-contact thermometer sensing a carotid artery

Abstract

Systems, methods and apparatus are provided through which in some implementations a non-contact thermometer determines a temperature of a subject from a carotid source point of the subject.

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 includes calculating the body temperature in reference to a representation of a surface of the body, a numerical representation of the electromagnetic energy of the carotid source point, a mathematical formula of an ambient temperature reading, an ambient air temperature reading, a representation of a calibration difference and a bias in consideration of the temperature sensing mode; and 
   a button operably coupled to the printed circuit board.   
     
     
         2 . The apparatus of  claim 1 , wherein the carotid artery source point further comprises:
 not more than one carotid artery source point.   
     
     
         3 . The apparatus of  claim 1 , wherein the bias further comprises:
 +0.5° C.   
     
     
         4 . The apparatus of  claim 1 , wherein the body temperature of the subject further comprises:
 a core temperature of the subject.   
     
     
         5 . The apparatus of  claim 1 , wherein the body temperature of the subject further comprises:
 an axillary temperature of the subject.   
     
     
         6 . The apparatus of  claim 1 , wherein the body temperature of the subject further comprises:
 a rectal temperature of the subject.   
     
     
         7 . The apparatus of  claim 1 , wherein the body temperature of the subject further comprises:
 an oral temperature of the subject.   
     
     
         8 . The apparatus of  claim 1 , wherein the printed circuit board further comprises:
 a microprocessor.   
     
     
         9 . The apparatus of  claim 1 , wherein the body temperature of the subject further comprises:
 a core temperature of the subject, an axillary temperature of the subject, a rectal temperature of the subject and an oral temperature of the subject.
