An electrical control system having a direct current to direct current regulator receiving a direct current supply input, wherein the regulator outputs a controlled voltage direct current inverter power feed. Embodiments of the invention include tracking a target across a plurality of beams of a multiple beam radar system in a roadway intersection and updating track files for targets within a roadway intersection. The terminal includes a transmission destination storage unit that stores identification information to identify the transmission destination of the authentication request and transmits the authentication request to the transmission destination identified with the identification information stored by the transmission destination storage unit. This can be accomplished without increasing any pitch area circuit or adding new wires in the memory array, and at minimal additional peripheral area.
