  • Network-based remotely-controlled power switch device
    Patent number: 6507273
    Abstract: A networked-based remotely-controlled power switch device is proposed, which can be coupled to an electricity-powered system, such as a personal computer (PC), a TV, or a video recorder, to allow the electricity-powered system to be powered ON or OFF through remote control by a remote computer system via a network system, such as Internet, Ethernet, or PSTN (Public Switched Telephone Network). This power switch device allows a user without an Internet account to be nevertheless able to use a remote PC system for remote ON/OFF control of the electricity-powered system. Further, in addition to instant ON/OFF control, this power device also allows the user to perform scheduled ON/OFF control to the electricity-powered system so that the electricity-powered system can be automatically powered ON or OFF at a specified time.
