Portable electronic device |
摘要 |
In a portable electronic device components (2) consuming electrical power during operation may generate heat. A temperature sensor (1) for sensing an ambient temperature (TS) of the portable electronic device may as a consequence not supply the correct temperature value. It is suggested to provide a compensator (4) for determining a compensated ambient temperature (TA) dependent on at least the sensed ambient temperature (TS) and information (Pi) related to the electrical power consumed by at least one of the components (2). After a power down and a reactivation of the portable electronic device, actual internal states (x(b)) of the compensation model are estimated dependent on last internal states (x(a)) stored at the power down, dependent on an estimated course of the sensed temperature (T*S) between the interruption and the reactivation, and dependent on an estimated course of the information (P*i) related to the electrical power consumed by the at least one heat source (2) between the interruption and the reactivation. |

1. A method for operating a portable electronic device, comprising
sensing a temperature with a temperature sensor of the portable electronic device, determining a compensated temperature for a given location of the portable electronic device depending on at least the sensed temperature, information related to electrical power consumed by at least one heat source of the portable electronic device, and internal states of a compensation model for determining the compensated temperature, at an interruption of an operation of the temperature sensor, storing last internal states of the compensation model, and at a reactivation of the operation of the temperature sensor, estimating actual internal states of the compensation model depending on the stored last internal states, depending on an estimated course of the sensed temperature between the interruption and the reactivation, and depending on an estimated course of the information related to the electrical power consumed by the at least one heat source between the interruption and the reactivation. |
