Abstract: A power consumption monitoring apparatus, comprising at least one electrical measurement device (210) for generating a signal indicative of the electrical power passing through an electrical power line (300) at the location of the measurement device, and at least one data controller (220) adapted to receive the signal from the measurement device and to convert the signal into a data transmission stream conveying at least one power consumption statistic. The data controller including a transmitter (221) for transmitting the data transmission stream across a communications medium and a display controller (230) including a receiver (231) for receiving the stream from the communications medium, the display controller adapted to convert the stream into one or more data display transmission signals for reception by a variety of display devices (310) to display power consumption statistics.

Abstract: A socket assembly enables a number of electrical appliances to be automatically isolated from, and reconnected to, an electrical power supply upon respectively switching off or on a “master” appliance. Generally, the assembly includes: a master electrical outlet and at least one slave electrical outlet, both connectable to a common power source; sensing means for sensing power drawn from the master electrical outlet; a controller operable to isolate the at least one slave electrical outlet from the power source when the sensing means detects a fall in power drawn from the master electrical outlet from a first, higher level to a second, lower level.
