An apparatus is provided for lifting a substrate. Particularly, the compounds are derivatives of hydroxyacetone, including dimers of both 1-hydroxyacetone and 1,3-dihydroxyacetone. The PCD requests maps and location tagged data from data providers and other for display on the PCD. The second light guide plate is disposed on the first light guide plate, and includes a third side, a fourth side opposite to the third side, and a second surface with a micro-groove structure. The modulated load current is based on the duty cycle. In alternative implementations, the present invention may comprise a reconfigurable processor comprising both reconfigurable devices with fine grained logic elements and reconfigurable devices with course grained logic elements or a reconfigurable processor comprising both reconfigurable devices with fine grained elements and non-reconfigurable devices with course grained elements.
