Abstract: A fast charging terminal is provided, which includes a battery, a USB interface, a switch module, a supply voltage detecting unit, a central processor, and a charging management unit. After the USB interface is connected to an intelligent charger, the switch module is switched on when the supply voltage outputted by the USB interface is within a safe supply voltage range such that the charging management unit converts the supply voltage and the supply current. The charging management unit decreases the supply voltage and increases the supply current to charge the battery.

Abstract: A content file communication system and method interconnects a client device with a content server using a wireless high-speed communication link. The client device connects to the content server and a user is able to view one or more content files stored in the content server. The user can select one of the content files for download. Each content file can be stored in the content server as multiple segments. Each segment can include a header portion and a body portion. The header portion can be encrypted and the body portion can be encoded. The content server transmits the selected content file over the high-speed communication link to the client device. At least a portion of the content file is transmitted at a rate higher than a presentation rate. At least a portion of the content file received by the client device is cached, then presented to an output.
