Samsung patents watch that adjusts body temp checks based on user activity
Samsung describes a wearable device that uses internal sensors to check if its own heat is interfering with body temperature readings. It calculates a 'user state index' based on movement and heart rate to decide how long to measure your temperature, ensuring the device is cool enough to be accurate.
In the filing’s own words
A wearable electronic device is provided. The wearable electronic device includes at least one first thermistor arranged in different heat generation positions in the wearable electronic device and configured to detect a temperature change of internal elements of the wearable electronic device, a temperature sensor configured to calculate a body temperature of a user based on the temperature change of the internal elements and a skin temperature trend of the user, and at least one processor configured to determine whether an internal temperature by the internal elements in the wearable electronic device is within a reference temperature range that does not have an influence on a calculation of the body temperature, based on a measured value of the at least one first thermistor, determine a user state index (UI) indicating whether the user is in a state in which the body temperature is measurable, when the internal temperature is determined to be within the reference temperature range, and measure the body temperature by adjusting a body temperature measurement period based on the UI.
What exactly they claim (claim 1)
1. A wearable electronic device comprising: at least one first thermistor arranged in different heat generation positions in the wearable electronic device and configured to detect a temperature change of internal elements of the wearable electronic device; a temperature sensor configured to calculate a body temperature of a user based on the temperature change of the internal elements and a skin temperature trend of the user; and at least one processor, comprising processing circuitry, individually and/or collectively configured to: determine whether an internal temperature by the internal elements in the wearable electronic device is within a reference temperature range that does not have an influence on a calculation of the body temperature, based on a measured value of the at least one first thermistor, determine a user state index (UI) indicating whether the user is in a state in which the body temperature is measurable, when the internal temperature is determined to be within the reference temperature range, and measure the body temperature during a body temperature measurement period that is adjusted based on the UI, wherein the body temperature measurement period is increased based on decrease in the UI and the body temperature measurement period is decreased based on increase in the UI, wherein the UI is determined based on a combination of at least two of user state variables, including the skin temperature trend of user, a user motion, and a heart rate variation.
