Patent ID: 7043380

Claim:
A programmable system for monitoring electricity consumption by a residence or business, the system comprising: (a) a Measuring Transmitting Unit integrated in a main circuit breaker or utility meter in the residence or business; comprising: (1) a means of receiving AC analog signals, converting the AC analog signals to DC analog signals, summing the DC analog signals, and outputting the information; (2) a microcontroller; (3) a power line carrier transmission interface controller; and (4) a power supply for powering the Measuring Transmitting Unit; and (b) a programmable Receiving Display Unit, comprising: (1) a power supply for powering the Receiving Display Unit; (2) a power plug; (3) a power line carrier transmission interface controller; (4) a data decoder; (5) a microcontroller; (6) memory associated with the microcontroller; (7) a visual display; and (8) a mechanism for inputting to the Receiving Display Unit; and wherein the Measuring Transmitting Unit translates current flowing in main service power circuit conductors to digitally encoded signals, and transmits the digitally encoded signals over existing power circuits in the residence or business; and the Receiving Display Unit receives the digitally encoded signals being emitted by the Measuring Transmitting Unit, decodes the digitally encoded signals, and translates them to the visual display for viewing; which system is not connected to a current transformer.
