ABSTRACT:
An intelligent AC outlet is adapted to mate with a plug. The plug carries coded information as to the power which it draws. A microprocessor, a switch and a sensor are carried in the outlet. The switch is interposed between the outlet and AC power lines and is operated by the microprocessor. The microprocessor continually scans the sensor. When the plug is inserted into the outlet, the sensor reads the code. If the microprocessor detects a valid code, it operates the switch applying power to the plug. If a valid code is not detected, the outlet remains electrically isolated from the power lines and this can not be overriden by the user.
