A polarizing plate has a polarizing membrane and an optically anisotropic layer formed from liquid crystal molecules. Self-aligned trenches are formed completely through portions of the SOI layer and the global BOX layer at source and drain regions. Insulated or floating electrodes of various selected geometries provide a means for sustaining or maintaining a modulated electric potential adapted for injecting modulated electrical current into the surrounding sub-surface medium. The gear assembly of the landing gear includes a unique floor base that receives and supports the input shaft.
