A computer system provides a wireless audio signal transmitter module which is capable of transmitting audio signal wirelessly from a host computer to at least one remote wireless signal receiver. The wireless audio signal transmitter module is connected to a sound effect interface for receiving audio signal from the computer. The audio signal is processed, modulated, and then transmitted out by an antenna. The wireless signal is received and processed by the audio signal receiver located within an effective transmission distance. The signal is then transmitted to a user via a microphone.

A computer system includes a wireless audio signal receiver module for receiving a wireless signal from a wireless transmitter separated from the computer system. The wireless audio signal receiving module includes a mode selector that is switchable between an audio mode and an instruction mode. When the mode selector is set to the audio mode, the wireless signal received by the receiver module is transmitted to a sound effect interface of the host device as audio signal and when the mode selector is set to the instruction mode, the wireless signal received by the receiver module is transmitted to a bus of the host device as instruction signal.

A device and method for removing heat from an object by spraying a cooling agent is disclosed. A cooling casing or a heat sink is mounted to the object. A spray nozzle is arranged to spray the cooling agent onto the cooling casing or the heat sink from a reservoir. The temperature of the object is detected. A controller receives the temperature and issues a signal to drive the spray nozzle when the detected temperature exceeds a predetermined upper temperature limit. The cooling agent is sprayed onto the cooling casing or the heat sink and evaporates by absorbing heat from the cooling casing or the heat sink thereby removing heat from the object. A fan is selectively provided for generating air flows to expel the evaporated cooling agent and thus enhancing heat removal from the object.
