A process evaluates an aging property of a distributed Bragg reflector laser. This method is named Hardened Core and is based upon the addition of an environmentally hardened circuit added into the computer system and connected to the microprocessor to provide monitoring and interrupt or reset to the microprocessor when a functional interrupt occurs. The encoder selects a current codeword which differs from the immediately preceding codeword by a fixed number of zero-to-one transitions on the first set of nodes and a fixed number of one-to-zero transitions on the second set of nodes. The placing of the decorated substrate in the mold is such that the surface carrying the design faces the inside of the mold. The Mobility Management Server can distribute lists to Mobile End Systems specifying how to contact it over disjoint networks. The stator vane further has an adjustment member secured to the stator vane so that it covers the inlet.
