Abstract:
The surface temperature of a portable device is estimated. The portable device includes a sensor for detecting the internal temperature of the portable device. The portable device also includes circuitry for estimating the surface temperature, using the internal temperature and an ambient temperature of the portable device as input to a circuit model. The circuit model describes thermal behaviors of the portable device. The circuitry is operative to identify a scenario in which the portable device operates, and determine the ambient temperature using the scenario and at least the internal temperature.
