Network-based remotely-controlled power switch device
First Claim
1. A network-based remotely-controlled power switch device for use with an electricity-powered system and a power source to allow a remote PC system to control the ON/OFF of the electricity-powered system via the Internet, the Ethernet, or the PSTN;
- the network-based remotely-controlled power switch device comprising;
(a) a main control unit;
(b) an Ethernet interface, under control of the main control unit and externally connected to the Ethernet, for controlling the data communication between the Ethernet and the main control unit;
(c) a modem interface, under control of the main control unit and externally connected via a modem to the PSTN, for controlling the data communication between the modem and the main control unit;
(d) a clock unit capable of generating a time signal representative of the current time;
(e) a Web server capable of serving up a remote-control Web page which provides a set of user-settable ON/OFF control options for remote power control of the electricity-powered system; and
(f) a switch unit having an input end connected to the power source and an output end connected to the electricity-powered system;
the switch unit being under control of the main control unit to control the ON/OFF of the connection between the power source and the electricity-powered system;
wherein when the remote PC system is successfully linked via the Ethernet interface or via the modem interface to the main control unit, the main control unit requests the Web server to serve up the remote-control Web page and then transfers the remote-control Web page back to the remote PC system, allowing the remote PC system to accept a user-specified ON/OFF control option and then transfer the user-specified ON/OFF control option back to the main control unit; and
in response to the user specified ON/OFF control option, the main control unit issues an ON/OFF signal to the switch unit to cause the switch unit to control the ON/OFF of the electricity-powered system.

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.
