Abstract: A mobile device includes sensors and a processor. The sensors are disposed on opposite edges of the mobile device respectively. The processor is configured to collect a first data set labeled with a right hand holding gesture, collect a second data set labeled with a left hand holding gesture, establish a determination model associated with the first data set and the second data set, and in response to the processor collects a third data set comprising the holding positions and the force values detected by the sensor, determine a current holding gesture according to the third data set in reference to the determination model.

Abstract: A thermoelectric dehumidifying device includes a case, on which a first air inlet, a second air inlet, and an air outlet are provided, and in which a thermoelectric element, a condenser, a heatsink, and a fan are provided. The thermoelectric element has a cold surface, to which the condenser is connected, and a hot surface, to which the heatsink is connected. The fan is provided between the second air inlet and the heatsink. Airflow flowing through the condenser will be cooled and dehumidified. Each fin of the condenser has a downwardly inclined bottom side, which facilitates the dripping of the water droplets condensed thereon. Said airflow will be mixed with external airflow drawn in through the second air inlet, and then blown by the fan to flow through fins of the heatsink, bringing away heat effectively and therefore improving the dehumidifying efficiency of the device.
