Provided is a control system that assists the vehicle operator in avoiding an obstacle by making use of simple information on the surrounding environment, and the effectiveness of such a system was demonstrated by computer simulations. The gate electrode silicon has a three-layered structure including a silicon-seed layer formed on the silicon dioxide layer, a silicongermanium layer formed on the silicon-seed layer, and a polycrystalline silicon layer on the silicongermanium layer. Similarly, the method, technique system may be utilized to remove fluids or other medium from the brain, tissues, and organs to minimize the effects of escaped air or negative pressure. In one aspect, an insulated conductive element is arranged inside the metal structure and is built into a longitudinal groove in a surface for receiving a longitudinal plastic holder wedged into the structure. A conductor is disposed through the silicon oxynitride layer for electrical connection to the control gate, and another conductor is disposed through the silicon oxynitride layer for electrical connection to a sourcedrain. The muscle cells can be autologous, allogeneic, or xenogeneic to the recipient.
