The invention is a set of novel bisphospholane ligands that can be complexed with transition metals. An example system receives GPS track information and GPS ground speed, determines a change in GPS track information and determines reliability of the GPS ground speed based on the determined change in GPS track information relative to the GPS ground speed. The second polymeric material andor surfactant are separated from the hydrophobic or amphiphilic compound, and subsequently recycled to the initial mixing step. An electro-optic device then forms image light in response to the display image data, and an optical system projects the image light to display the image. Subsequently, only a few parameters are required to encode this function in each region.
