5 results about "Body core temperature" patented technology

A garment can include a pocket to hold a removable electronic device. The electronic device can sense body core temperature, heart rate, skin conductivity, blood oxygen level, and geo-spatial location of the wearer, and transmit this data wirelessly to a mapping application. A viewer of the application can track the location and the health status of the wearer. A leader at a search and rescue command post can easily monitor both the location and well-being of personnel through the mapping application while they are on a mission. An algorithm on the backend can determine a health status color based on the sensor data. The pocket design facilitates insertion and removal of the electronics, and ensures that sensors are positioned at optimal locations on the body.

An infrared thermopile sensor includes a silicon cover having an infrared lens, an infrared sensing chip having duo-thermopile sensing elements, and a microcontroller chip calculating a temperature of an object. The components are in a stacked 3D package to decrease the size of the infrared thermopile sensor. The infrared sensing chip and the microcontroller chip have metal layers to shield the thermal radiation. The conversion from wrist temperature to body core temperature uses estimated air temperature based on inside temperature, wrist temperature from thermopile sensor plus the ratio of the thermal resistance between watch case to air and the thermal resistance between thermopile sensor to watch case, and fixed humidity or imported humidity level to calculate the body core temperature based on experimental data and curve fitting. The skin temperature compensation can be set differently for different sex gender, different standard deviation of wrist temperature and external relative humidity reading.
