Abstract: An electronic device and a battery power displaying method of the electronic device are provided. The method includes following steps. Estimated power of a battery module in the electronic device is obtained. A slope parameter is adjusted according to a charging and discharging state of the electronic device and the estimated power. The estimated power is converted into mapping power based on the slope parameter. The mapping power is disposed on a user interface.

Abstract: A dual-processor system includes a power supply, a temporary memory, a non-volatile memory and two processors. The non-volatile memory stores an initialization program code, a first configuration file corresponding to a first operating system, and a second configuration file corresponding to a second operating system. Compared to the first operating system, the second operating system has a shorter interrupt latency and a shorter thread switching latency. After the power supply starts to supply power, the first processor executes the initialization program code to perform operations of initializing the temporary memory, loading the second configuration file into the temporary memory, notifying the second processor to fetch the second configuration file from the temporary buffer, loading the first configuration rile into the temporary memory and establishing the first operating system according to the first configuration file.

Abstract: A synchronization rectification device is connected with a secondary side of a transformer of a power supply and an output capacitor. The synchronization rectification device includes a rectification switch, a voltage-controlled switch module and a rectification controller. The rectification switch is connected between the secondary side and the output capacitor. The voltage-controlled switch module connected with the secondary side has a voltage-division capacitor and receives a secondary voltage generated by the secondary side. The rectification controller is connected with the rectification switch and the voltage-controlled switch module. When the secondary voltage rises to a switching voltage value below a first voltage value, the rectification controller controls the rectification switch to be turned off. After the rectification switch is turned off, the voltage-controlled switch module is turned off, and the voltage-division capacitor receives the secondary voltage.

Abstract: A motor includes a stator coil, a rotor and a driving unit. The stator coil is configured to be electrified to generate a magnetic force. The rotor is rotatably coupled with the stator coil and includes a magnetic member facing the stator coil. The driving unit is electrically connected to the stator coil and outputs a driving signal to the stator coil. An electrical characteristic value of the driving signal increases in a gradual manner. The rotor outputs a motive power that is gradually increased during a process the rotor rotates from an electric angle back to a same electric angle. In addition, an activation control method for the motor and a fan are also disclosed.
