Embodiments of the present disclosure provide a method for temperature detection. The method comprises obtaining a sensed temperature from a sensor, the sensor being in a mounted mode where the sensor is thermally radiated by a variable heat source and a fixed heat source; determining a temperature change rate of the sensor and at least one affecting factor that affects temperature sensing of the sensor; and determining a temperature of the variable heat source based on the sensed temperature, the temperature change rate, and the affecting factor. According to the method of the present disclosure, the temperature of the variable heat source such as an ambient temperature can be obtained or determined without a dedicated sensor and cables. With this method, the ambient temperature can be determined by a sensor for sensing a temperature of a heating element such as a battery, a control unit or the like. In this way, extra spaces and product designs for mounting a dedicated sensor for the ambient temperature are no longer needed, which reduces costs of the product. Furthermore, user experience can be improved without increasing costs.

A wearable device includes: a base to be worn on a head of a user; a first sensor that is provided to the base to be at a distance from a surface of the user's head and measures a first signal relating to a temperature of the surface of the user's head; an estimation circuit that estimates a body temperature of the user based on the first signal; and a display that presents the body temperature of the user estimated by the estimation circuit.

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 detected ambient temperature 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.

The present embodiment provides a body temperature measuring patch using an infrared temperature sensor, which enables the body temperature to be measured more accurately and quickly when a body temperature is continuously monitored by applying a surface mounted device (SMD)-type infrared (IR) temperature sensor and thus implementing a patch-type thermometer.

A method includes capturing and scaling VLC and an IAS outputs to generate a scaled VLC output and a scaled thermal output (STO), aligning the scaled VLC output to the STO to generate an aligned image based on the scaled VLC output and the STO, determining alignment value(s) based on the aligned image, a laser pointer outputting a light beam to produce a laser dot on a target, and capturing a further output of the VLC. The method includes displaying the further output of the VLC (including a representation of the laser dot (RLD)), and an alignment marker, shifting the alignment marker and/or the RLD to a common position; determining coordinate(s) of the output of the IAS based on coordinate(s) of the further output of the VLC where the alignment marker and the RLD are shown at the common position; and storing the coordinate(s) of the output of the IAS.
