A silicon-on-insulator substrate having improved thickness uniformity as well as a method of fabricating the same is provided. The next step is defining one or more repeater ranches in an interstice of the IC and generating a repeater placement plan for placement of repeater elements according to the repeater ranch boundary constraints. The second filter is provided for failure detection and disposed downstream of the first filter. Current mood of the user is identified based on the one or more mood indicators. In one embodiment, the temperature system comprises a plurality of conductors patterned to conduct current in directions that generate 2N multipole magnetic moments that interact to suppress the magnetic fields generated by the current conducting through the plurality of conductors, where N is an integer that is greater than one.
