A corrosion resistant member to be exposed to a halogen-containing gas atmosphere or a halogen-containing gas plasma atmosphere, comprising a substrate and a plurality of layers deposited thereon including a layer of rare earth fluoride providing the outermost surface and a layer of rare earth oxide having a porosity of less than 5% underlying the rare earth fluoride layer. A switching device selectively connectsdisconnects the at least one of the starter generator and the supercapacitor bank tofrom the at least one of the service battery and the plurality of electrical devices. The catalyst exhibits a regeneration coefficient of at least 95% after ethylation of the benzene with ethylene at a benzeneethylene mole ratio of less than 10. By determining the received power in two or more harmonics, and correlating them to each other, the distance may be estimated.
