An instructional device and associated method for illustrating the positions of keys and their associated notes on a keyboard are provided. The transponder intermediary device comprises a transponder-receiving slot and a vehicular interface. The plurality of longitudinal reflector sheets are arranged between the rows of the solar panels. The stator assembly includes an outer diameter, a stator core, and a stator winding. Irradiating is conducted through the chalcogenide material to the projecting metal mass effective to break a chalcogenide bond of the chalcogenide material at an interface of the projecting metal mass outer surfaces and diffuse at least some of the projecting metal mass outwardly into the chalcogenide material.
