Patent ID: 8258654

Claim:
A method comprising: receiving a wireless signal from an occupancy sensor; and controlling power in response to the wireless signal; where the occupancy sensor includes only a limited source of power to transmit the wireless signal; where the wireless signal is received at a power or surge strip having a power cord with an electrical plug with prongs to receive power from an electrical receptacle such that the power or surge strip can be removed from an interior or exterior building space without disconnecting any permanent building wiring; where the power or surge strip includes multiple receptacles and a master switch to control the flow of power from the electrical plug to one or more of the receptacles; where the power or surge strip includes processing logic to implement an unoccupied time delay and a user interface to adjust the unoccupied time delay; where the flow of power from the master switch to at least one of the multiple receptacles is controlled by a power switch at the power or surge strip in response to the wireless signal; and where the power switch turns off the flow of power from the master switch to at least one of the multiple receptacles after delaying for an unoccupied time delay after no longer receiving a subsequent wireless signal from the occupancy sensor.
