An interface to interconnect Network Processor and Scheduler chips in a multi-chip system includes a limited set of messages and circuit arrangements to generate the limited set of messages. The hybrid vehicle has a combustion engine and an electric motor each providing a torque for operating the hybrid vehicle. The regulating device includes an electronic control circuit that is provided to control the current regulator of each coil of a number of coils, in order to reduce a variance between the actual current intensity in that coil and the reference current intensity measured by the comparator of that coil. By providing a rank for dangling web pages, the present system allows the concentration of crawling resources on those dangling web pages that have the highest rank in the uncrawled region.
