BODY CORE TEMPERATURE MEASUREMENT
First Claim
1. An apparatus for measuring body core temperature comprising:
- a light guide comprising an internally reflective tube, the light guide coupled to an earpiece, the light guide having a first end and a second end, and the light guide comprising an aperture positioned at the second end;
a first sensor positioned at the first end of the light guide; and
a processor coupled to the first sensor;
wherein the first sensor is operable to sense infrared radiation from an infrared source at the second end of the light guide; and
wherein the processor is configured to determine a temperature of the infrared source at the second end of the light guide via a transfer function that correlates a measure of the infrared radiation observed by the first sensor and an effect of radiation of the light guide.

Abstract
An apparatus for measuring body core temperature includes a light guide with an internally reflective tube. The light guide is coupled to an earpiece, and has a lens or an aperture positioned at one of its ends. A sensor is positioned at the other end of the light guide, and a processor is coupled to the sensor. The sensor senses infrared radiation from an infrared source at the end of the light guide, and the processor determines a temperature of the infrared source at the end of the light guide via a transfer function that correlates a measure of the infrared radiation observed by the sensor and an effect of radiation of the light guide.
