Abstract: An example method includes receiving electrical power via a physical connector of a mobile computing device; determining, by a controller of the mobile computing device, a value of a temperature of a virtual temperature sensor, the value representing a difference between a temperature measured by a first temperature sensor of a plurality of temperature sensors of the mobile computing device and a temperature measured by a second temperature sensor of the plurality of temperature sensors, wherein a distance between the first temperature sensor and the physical connector is less than a distance between the second temperature sensor and the physical connector; determining, based on the value of the temperature of the virtual temperature sensor, whether an overheat event has occurred; and responsive to determining that the overheat event has occurred, reducing an amount of electrical current flowing through the physical connector.

Abstract: A mobile device includes a panel audio loudspeaker including a display panel and an actuator coupled to the display panel. The mobile device includes a temperature sensor arranged to sense a temperature of the display panel, and an electronic control module in communication with the actuator and the temperature sensor. The electronic control module is programmed to perform operations including: obtaining, from the temperature sensor, data indicating a temperature of the display panel; and based on the data indicating the temperature of the display panel, adjusting a power signal provided to the actuator to drive the panel audio loudspeaker. The power signal can be adjusted by selecting, based on the data indicating the temperature of the display panel, a target temperature of the display panel; mapping the target temperature to a target power level; and changing the power signal provided to the actuator to the target power level.
