A device such as an electric motor, an electric generator, and a regenerative electric motor includes a plurality of independent energizable electromagnetic assemblies. In one example, a method may include receiving a packet data channel request and an invitation message at a first node over an air interface from a mobile device. The results of the evaluation are the fancy yarn parameters such as base yarn mass, base yarn diameter, stub distance, mass increase of a stub, slub diameter increase, stub diameter, slub length andor slub total mass. When in an active mode of operation, the automatic nacelle conversion function provides a fully automatic nacelle controller requiring no pilot input. The die is used to deform a reflective surface such that the surface produces optically varying effects.
