Abstract: An electronic device includes a shell, a thermal element, a controller and a fan. The shell defines a first air outlet and a second air outlet. The controller controls the fan to rotate clockwise to generate a first air current to dissipate the heat generated by the thermal element out of the first air outlet in a first preset condition, and control the fan to rotate anticlockwise to generate a second air current to dissipate the heat generated by the thermal element out of the second air outlet in a second preset condition.

Abstract: An electronic device in which or by which air humidity can be controlled includes an enclosure and a humidifying module. The humidifying module is located in the enclosure. The humidifying module includes a chamber and a launcher. The launcher is movable relative to the chamber. The chamber stores the fluid required to create humidity. When the launcher is open, the humidification fluid in the form of vapor can emanate from the fluid chamber.

Abstract: A physiological index detection system includes a computer and a mouse, the mouse includes a shell and a physiological index sensing unit and communicates with the computer. The computer includes a display screen and a display control unit. The physiological index sensing unit senses physiological characteristics of a living being who touches the mouse and generates an analog physiological index signal. The physiological index detection system processes the analog physiological index signal to obtain a digital equivalent result in health terms. The display control unit displays the result on the display screen and advice concerning an adverse finding. The disclosure also provides a mouse and a physiological index detecting method.

Abstract: A smart reminder system includes an intelligent web camera and an electronic device. The intelligent web camera includes a detecting module, and the electronic device includes a determining module coupled to the detecting module and a warning module coupled to the determining module. The detecting module detects a position of at least one eye to obtain a gaze direction of the at least one eye, and the determining module determines whether the gaze direction satisfies with a standard. When the gaze direction does not satisfies with the standard, the warning module warns a user to adjust the posture to a standard sitting posture. The disclosure further provides a smart reminder method.
