A group or solo monitoring system and method for collision avoidance that uses a transceiver circuitry mounted on a vehicle. A pad nitride layer is formed on the first oxide layer. During the current flow electrical power is extracted by the drop in voltage of current passing through the unit. The attachment portion is entirely disposed within an interior of the set of membranes. The rotor hub includes an internal mounting assembly, preferably comprised of a series of interconnected mounting plates, positioned adjacent a series of foil shaped openings in the rotor hub into which the root end of turbine blades can be inserted and removably mounted to the internal mounting assembly. Interlayers of the present invention comprise a thermoplastic polymer, a plasticizer, and a fumed silica that has been modified to impart hydrophobic character.
