The invention relates to a method for detecting a rollover situation in such a way that a restraint, such as belt tighteners or head airbags, can be released at the right time during rollover. In one mode, the input line power is fed straight through to the load. A design structure for designing, testing or manufacturing an integrated circuit is tangibly embodied in a machine-readable medium and includes elements of a solid state voltage multiplier. The dedicated sector is to be dedicated to use for a first computer process. The units further have an optical receiver for receiving light from other lighting units. This device comprises, on a common substrate, at least one antenna of the slot type formed by a closed curve, known as a slot antenna, electromagnetically coupled to a first supply line, and an antenna radiating parallel to the substrate, positioned inside the slot antenna and connected to a second supply line.
