A helmet manufactured for one specific person, made from rigid synthetic materials, to specifications determined by data obtained from a previously obtained MRI scan of that person’s brain, intracranial arteries, and skull. In the method for driving a PDP, successive field periods, each including a reset period for initializing the state of respective cells, an address period for selectively discriminating cells to be turned on from cells not to be turned on and for performing an addressing operation, and a sustain period for discharging the addressed cells are performed. The multiplexed multi-electrode component includes two or more individually addressable satellite electrode structures electrically coupled to a common conductor.
