Abstract
A method distinguishes electrical signals corresponding to an activation or deactivation of a single electrical power consuming device from an electrical signal that supplies electricity to multiple electrical power consuming devices has been developed. The method includes generating signatures corresponding to activation and deactivation of a plurality of electrical devices from a transformation of an electrical power signal using sparse deconvolution to cluster and then identify the activation and deactivation of one of the plurality of electrical devices.
