Abstract: A charge demand controller device for electric vehicles or the like, preferably for installation with an existing residential electrical control panel, connects between a main switch and the electrical control panel made to operate at a maximum amperage value. The device includes a controller unit that constantly monitors an actual total load current at the input line connector from the main switch, and selectively operates a load switch controlling an electric vehicle supply equipment (EVSE) upon the actual total load current being above or below a trip value being a predetermined safety ratio of the maximum amperage value.

Abstract: A CAD tool that supports an overlay-enabling operating mode. After the overlay-enabling operating mode is entered, the layout-editing facility permits modifications to the interconnect structure of an integrated circuit that is being designed regardless of whether a particular modification interferes with an existing pattern of metal fill. For example, a new signal wire can be added to electrically connect two specified points in the layout in a manner that causes the wire to cross over one or more metal-fill tiles. The CAD tool then modifies the fill pattern to get rid of any design-rule violations caused by the modifications to the interconnect structure by removing and/or modifying one or more fill tiles.
