  • Patent number: 7231482
    Abstract: A method and system for monitoring utility meter status, and transmitting a status message via an output device connected to a universal communications interface in the event that the utility meter status meets a predetermined condition. Typically, the predetermined condition is a power loss, signified by a drop in voltage or current. The system is connected to a utility meter, such as an electric meter. The voltage level of the electric meter is monitored through a voltage input interface. An analog-to-digital converter transforms the voltage waveform into a series of digital is data packets, which are then transmitted to a microprocessor. The microprocessor monitors the digital signal for a power loss indication, or other predetermined condition. Once a predetermined condition is met, the microprocessor transmits a status message across a universal serial bus to a universal communications interface.
