Abstract
A supplemental energy register in which successive increments of consumed electrical energy are detected at a kilowatthour meter, and are translated into electrical pulse signals. Digital calculation and display logic is operated by the pulses, either directly or through intermediate transmission over the household network. Kilowatthours are directly accumulated in increments corresponding to those sensed at the meter, while net cost is computed by chain addition utilizing the prevailing cost per increment rate, which is maintained in a keyboard controllable memory. The register may desirably be inserted in the leads connecting an electric utilization device to the local common network.
