Methods and systems for distributed failover in a vehicle network, including processor load shedding to reallocate processing power to applications controlling critical vehicle functions and providing for failover in a vehicle network according to the criticality of the affected vehicle function. There is provided an optical source configured for supplying the optical signal to one end of the hollow optical fiber and a sensor designed to detect at one end of the hollow optical fiber the optical signal transmitted throughout the length of the fiber itself. The collimated light beam is deflected by the deflection unit based on the evaluation result from the evaluation unit until a predetermined intensity is reached as detected by the light receiver. A preference indicates a target search engine referenced by the search query. When the CPU boots, code for the boot copier is executed so that the CPU instructions are copied from the nonvolatile serial configuration memory to the volatile fast bulk memory. By applying the voltage which attenuates while alternating to the upper holding mechanism 7, residual attracting force between the bonded substrate and the upper holding mechanism 7 is reduced, thereby enabling the bonded substrate to be dechucked from the holding mechanism more surely in a shorter time period.
