3 results about "Body core temperature" patented technology

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.

An infrared thermopile sensor includes a silicon cover with an infrared lens, an infrared sensing chip with dual thermopile sensing elements, and a microcontroller chip to calculate the temperature of an object, the elements using stacked 3D packaging to reduce volume. The infrared sensing chip and microcontroller chip can have metal layers to shield from thermal radiation. The non-contact infrared thermopile sensor of the invention can convert wrist temperature to body core temperature. Body core temperature is calculated from detected ambient temperature information, default or input water vapor pressure information, etc. There can be different conversion methods of wrist temperature to body core temperature at different temperature, gender, and relative humidity.

A temperature sensing system includes an insulator having a thermal resistance that is controllable from a first thermal resistance to a second thermal resistance, and at least one temperature sensor operable to sense temperature at first and second sides of the insulator. A processor is configured to control the thermal resistance of the insulator to change from the first thermal resistance to the second thermal resistance.
