Patent 11874173 was granted and assigned to Exergen Corporation on January, 2024 by the United States Patent and Trademark Office.
A temperature detector is provided that is particularly suited towards the differential measurement of foot temperatures in diabetics. A radiation sensor views a surface area of the body and provides a radiation sensor output. Electronics coupled to the radiation sensor and an ambient temperature sensor compute a normalized surface temperature of the area normalized to a specified ambient temperature as a function of a sensed ambient temperature and a sensed radiation.
