Abstract
A computerized method for detecting a core temperature of a person, the method may include: receiving multiple temperature readings obtained by scanning a temperature sensor across a skin area of a person, the skin area covers at least one blood vessel, to provide multiple temperature readings; the multiple temperature readings include a peak temperature reading; and determining, by a processor, an estimate of the core temperature of the person in response to at least one temperature reading that differs from the peak temperature reading.

A computerized method for detecting a core temperature of a person, the method comprising:
- receiving multiple temperature readings obtained by scanning a temperature sensor across a skin area of a person, the skin area covers at least one blood vessel, to provide multiple temperature readings, wherein the multiple temperature readings comprise a peak temperature reading,
- receiving upon scanning, from one or more auxiliary sensors, a spatial measurement associated with a distance between the skin area of the person and the temperature sensor,
- determining, by a processor, an estimate of the core temperature of the person in response to at least one temperature reading that differs from the peak temperature reading, and the distance between the skin area of the person and the temperature sensor, wherein the estimate is determined by calculating an intermediate estimate of the core temperature by selecting the received temperature readings that fall within a range between 70 and 90 percent of the peak temperature reading, and by dynamically compensating for the measured distance.
- taking an average of received temperature readings in that range as the intermediate range,
- updating the intermediate estimate by applying a correction function that at least partially compensates for inaccuracies associated with the temperature readings, wherein the correction function is determined by measuring errors in temperature readings, over a range of temperatures, occurring when scanning the temperature sensor across a skin area of a person, and
- applying the correction function to provide for a given measured temperature, a temperature to add to the intermediate estimate to determine the estimate of the core temperature of the person.

A non-transitory computer readable medium that stores instructions for:
- receiving multiple temperature readings obtained by scanning a temperature sensor across a skin area of a person, the skin area covers at least one blood vessel, to provide multiple temperature readings, wherein the multiple temperature readings comprise a peak temperature reading,
- receiving upon scanning, from one or more auxiliary sensors, a spatial measurement associated with a distance between the skin area of the person and the temperature sensor,
- determining, by a processor, an estimate of the core temperature of the person in response to at least one temperature reading that differs from the peak temperature reading, and the distance between the skin area of the person and the temperature sensor, wherein the estimate is determined by calculating an intermediate estimate of the core temperature by selecting the temperature readings that fall within a range between 70 and 90 percent of the peak temperature reading, and by dynamically compensating for the measured distance,
- taking an average temperature reading in that range as the intermediate estimate,
- updating the intermediate estimate by adding a correction function that at least partially compensates for inaccuracies associated with the temperature readings, wherein the correction function is determined by measuring errors in temperature readings, over a range of temperatures, occurring when scanning the temperature sensor across a skin area of a person, and
- applying the correction function to provide for a given measured temperature, a temperature to add to the intermediate estimate to determine the estimate of the core temperature of the person.
