  • System for monitoring and modifying operation of an electrical energy consuming device corresponding to electrical energy consumption
    Patent number: 8717594
    Abstract: A system adjusts at least one operational parameter for at least one electrical energy consuming device. The system monitors electrical energy consumption measurements for operational activity periods, identifies an electrical energy consumption measurement difference between an electrical energy consumption measurement for an operational activity period and an electrical energy consumption measurement for a corresponding operational activity period, and modifies an operational parameter for the electrical energy consuming device in response to the difference being greater than a predetermined threshold. The modified operational parameter is sent to the electrical energy consuming device to enable modified operation of the electrical energy consuming device.
    Type: Grant
