60. A method comprising:
-
measuring, at first and second times, first and second electrical power signals of at least one electrical circuit; frequency analyzing the measured first and second electrical power signals; computing components of first and second electrical load characteristics from the frequency analyzed measured first and second electrical power signals, respectively; and identifying at least one change in operational state of at least one electrical appliance of the at least one electrical circuit based upon a difference in the components of the first and second electrical load characteristics. - View Dependent Claims (61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79)
