Patent ID: 7324876

Claim:
A power management system, comprising: a plurality of power switch control circuits, each of said power switch control circuits configured to selectively disengage one or more electrical loads; a plurality of wireless receivers, each connected to one of said power switch control circuits; at least one wireless transmitter; and a central station, said central station causing messages to be transmitted by said at least one wireless transmitter to said power switch control circuits, said power switch control circuits responding thereto by disengaging electrical loads according to locally configurable settings; wherein one or more of said power switch control circuits comprises a set of controllable switches interposed between a power supply line and said plurality of electrical loads; wherein said controllable switches are switched according to a locally configurable priority to disengage the electrical loads; and wherein one or more of said controllable switches comprises a bimetal member that is normally closed thereby allowing current to flow to the electrical load associated therewith, said bimetal member being deformed by a control signal which causes heating of the bimetal member and thereby results in the opening of the controllable switch and stoppage of said current flow.
