Abstract: A charging gun for charging an electric vehicle including a charging connector and a charging cable is provided. The charging connector has an insertion portion and a turning portion connected to the insertion portion, and an included angle between the insertion portion and the turning portion is greater than or equal to 90 degrees and less than or equal to 100 degrees. The charging cable is connected to the turning portion, and the charging cable includes a plurality of wires arranged in parallel in one direction, to avoid the problem that the charging cable hangs down onto the road and causes danger to passersby.

Abstract: A smart parking management system and a smart parking management method are provided. The system includes a first smart pole, multiple second smart poles, and a processing device. An image capturing range of the first smart pole covers an entrance of a road section. An image capturing range of each second smart pole covers at least a parking space of the road section. The processing device is communicatively coupled to the first smart pole and the second smart poles. The processing device identifies first vehicle information of a first vehicle entering the road section according to an image stream captured by the first smart pole, obtains a movement trajectory of the first vehicle in the road section based on the first vehicle information and an image stream captured by each second smart pole, and determines where the first vehicle is parked according to the movement trajectory.

Abstract: A power control method for a portable electronic device. The portable electronic device comprises a power supply unit and a volatile memory for storing data when the power supply unit supplies power thereto. First, the portable electronic device is set to enter a deep sleep mode. Then, data accessed from the volatile memory is transferred to a non-volatile memory. Finally, except for maintaining sufficient power to restore the device, the power supply unit is turned off.

Abstract: A main computer for vehicle includes a central processing unit and a programmable logic device. The central processing unit is configured for controlling operations of the main computer. The programmable logic device is coupled to the central processing unit and includes a built-in power state machine for managing power statuses of the main computer. The power state machine includes a turn-off status, an operating status, and a predetermined status located between the turn-off status and the operating status.
