"Smart" AC receptacle and complementary plug
First Claim
1. An intelligent outlet adapted to matingly receive a plug said pug carrying optically coded information in addition to the presence of said plug in said outlet, information at least indicative of the power to be drawn by said plug and the load attached thereto, said outlet comprising at least one socket adapted to receive the plug and having optical sensor means carried in the outlet adapted to read the code of the plug when the same is inserted into said socket, microprocessor means carried in the outlet and in electrical communication with said sensor, and switch means carried in the outlet and operated by said microprocessor, said switch means being interposed between a power line and a contact of said socket, said microprocessor adapted to scan said sensor whereby when the plug is inserted into said socket and said sensor detects a code valid for said outlet, said microprocessor activates said switch means thus to apply power to the plug.

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.

- 1. An intelligent outlet adapted to matingly receive a plug said pug carrying optically coded information in addition to the presence of said plug in said outlet, information at least indicative of the power to be drawn by said plug and the load attached thereto, said outlet comprising at least one socket adapted to receive the plug and having optical sensor means carried in the outlet adapted to read the code of the plug when the same is inserted into said socket, microprocessor means carried in the outlet and in electrical communication with said sensor, and switch means carried in the outlet and operated by said microprocessor, said switch means being interposed between a power line and a contact of said socket, said microprocessor adapted to scan said sensor whereby when the plug is inserted into said socket and said sensor detects a code valid for said outlet, said microprocessor activates said switch means thus to apply power to the plug.
- 4. An intelligent AC outlet of conventional in-the-wall mount configuration which is adapted to mate with a conventionally configured plug carrying coded information as to the current to be drawn from the AC power lines comprising two sockets each one adapted to receive one such coded plug, sensor means carried in the outlet and adapted to read the code carried on the plug when the same is inserted into either of said sockets, microprocessor means carried in the outlet and in electrical communication with said sensor means, and switch means interposed between the AC power lines and a respective one of said sockets, the last-mentioned means being operated by said microprocessor, said microprocessor adapted to scan said sensor means such that when the plug is inserted into either of said sockets and a valid code detected, said microprocessor operates said switch means thus to apply power to the plug.

11. For use with a microprocessor controlled AC outlet wherein the outlet includes a socket and a code reading sensor, a plug adapted to be inserted in the socket and carry electrical power, and a bar type optical code carried on said plug, said code carrying information in addition to its presence in the outlet, as to the current to be drawn by said plug so that when the same is inserted into the socket, the sensor communicates a signal to the microprocessor which, if valid, causes the microprocessor to turn on the socket and apply power to said plug.
