Abstract: A refrigerating system include a heat management module, a direct cooling module, a plurality of heat exchange modules, and a plurality of cooling pipes. The heat management module may send, to the direct cooling module, control information that indicates that the charging pile needs to charge a terminal device. The direct cooling module may be configured to convert a gas refrigerant transmitted in a second pipe assembly into a liquid refrigerant, and transmit the liquid refrigerant to each heat exchange module and each cooling pipe through the first pipe assembly.

Abstract: A method for switching a power mode of a computer device is adapted to a computer accessory. The method comprises setting a power management mode of the computer device to be awakened when connected to the external power; connecting the computer accessory to a host connector of the computer device to establish a power connection and a communication connection through a host signal pin set of the host connector; through the power connection and the communication connection, detecting and determining the power mode of the computer device; and executing one of following steps upon receiving the switch signal: when the power mode is the normal operation state, transmitting a communication signal; when the power mode is the Suspend-To-RAM state, transmitting a wake up signal; and when the power mode is the Suspend-To-Disk state or the shutdown state, temporarily cutting off the external power and then restoring the external power.

Abstract: A method for waking up a notebook computer is adapted to a computer accessory. The notebook computer includes a host connector including a power receiving. The method includes setting a power management mode of the notebook computer to be awakened when connected to the external power, to switch a power state of the notebook computer from a waiting to be awakened state to a normal operation state; connecting the computer accessory to the host connector to establish a power connection through the power receiving pin and deliver an external power to the notebook computer; temporarily cutting off the external power by the computer accessory and then restoring the external power; when the power state of the notebook computer is the waiting to be awakened state, performing a wake-up operation with the notebook computer to switch to the power state to be the normal operation.

Abstract: A composite mouse assembly for a computer includes a mouse case. A computer interface encoder is contained in the mouse case. A positional sensor is connected to the interface encoder for controlling a screen indicator used for selecting menu items appearing on a display screen of the computer. A wireless remote control device is connected to the positional sensor and includes a plurality of user-activated direction control keys for transmitting digital serial encoded signals. A receiver unit is contained in the mouse case for receiving and amplifying the digital signals transmitted by the remote control device. A decoder is provided for interpreting the digital signals transferred by the receiver unit into one of a plurality digital direction control signals corresponding to the direction control keys of the remote control device. A converter converts the digital direction control signals to analog signals.
