Electric outlet for stanby power interruption and power saving, control method thereof, and power saving system
First Claim
1. An electric outlet comprising:
- a connector for extracting clock signals and data signals of a computer input device;
a main outlet for supplying AC power to a computer;
at least one auxiliary outlet for supplying AC power to at least one computer peripheral device; and
a main controller for receiving AC power, supplying the AC power to the main outlet, determining a user'"'"'s computer using state according to the clock signals and the data signals extracted by the connector, interrupting power supply to the auxiliary outlet when the user does not use the computer for a predetermined setting time, and starting power supply to the auxiliary outlet when the user uses the computer.

Abstract
Disclosed is an electric outlet which comprises: a connector for extracting clock signals and data signals of input devices; a main outlet for supplying AC power to a computer; an auxiliary outlet for supplying AC power to peripheral devices; and a main controller for receiving AC power, supplying the AC power to the main outlet, determining a user'"'"'s computer using states according to the clock signals and the data signals, interrupting power supply to the auxiliary outlet when the user does not use the computer for a setting time, and starting power supply to the auxiliary outlet when the user uses the computer. The clock and data signals are extracted, and when a user does not use the computer, power supply to the peripheral devices are interrupted, and when the user uses the computer, power supply to the peripheral devices is started thereby reducing power consumption during the pause period.
