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.
Claims8
In a local energy consumer network, apparatus for evaluating cumulative energy consumption and the net cost thereof, comprising:
- (a) metering means, in circuit with said network, for detecting consumption of successive specified increments of energy, said in circuit metering means providing successive pulses as indicative of current flow;
- (b) pulse shaper means, responsive to said in circuit metering means, for generating an actuating pulse of predetermined duration, upon detection of each said successive pulse provided by said in circuit metering means;
- (c) counter means incremented upon each occurrence of a said actuating pulse from said pulse shaper means;
- (d) means, responsive to said counter means, for producing control pulses in respective response to each said specified increment of said counter means;
- (e) calculator display means, calibrated at a prevailing rate of cost per said specified increment, for presenting cumulative energy cost increments;
- and
- (f) electrically isolating coupling means, responsive to said means for producing control pulses, for incrementing said calculator display means by one of said cost increments per each said control pulse.
