Abstract: Method for receiving and converting transmission signals transmitted according to different protocols, including steps of receiving a transmission signal, judging according to which protocol the transmission signal is transmitted and executing mapping operation corresponding to the transmission signal.

Abstract: A system, method and apparatus for simplifying the interpretation of suspend and wake-up functions in an operating system for information appliance is disclosed. An input device integrates the suspend and wake-up functions into the same key, and a communication signal receiver accepts the signal from the input device.

Abstract: A method for allowing to automatically wake up a computer system to receive messages transmitted by a communication apparatus via a communication protocol and then to make the computer system enter into the suspend mode. When the computer system wakes up by the incoming message transmitted via the communication protocol, a Fax/Answering machine function is triggered to receive the Fax/voice message. After the incoming message is completely transmitted, the system suspend function is triggered to make the computer system enter into the suspend mode immediately without waiting for a period of time, therefore, the objective of saving electric power is achieved adequately.
