A pallet exhibiting a three dimensional shaped and buoyant inducing body with enhanced load supporting capabilities. The substrate includes a plurality of first electrodes disposed on the first region and an insulation member selectively disposed in the first region. A programming signal is then applied to a target memory cell in the memory array, the programming signal having a programming parameter which depends at least in part on the most recent programming time. The coating material may be a silicone compound that is curable such that the coating material cures into a substantial non-porous silicone. The return light due to SBS generated in the dummy transmission path is extracted via the optical inputoutput section. A second beam is directed along a second axis into the field.
