In general, this disclosure is directed to techniques for computing a positioning solution for a mobile unit based on signals received from the satellite navigation system and the wireless communication system. The conversion engine includes a serial-to-parallel data conversion device receives a serially received data word and provides a parallel output data word. The dispensing system allows texture material to flow out of the container assembly and onto the surface such that a visible physical structure of the texture material corresponds to a desired texture pattern. The apparatus further includes a lower slip, concentrically disposed about the mandrel, for engaging with the internal portion of the well, and lower cone abutting an underside of the lower slip, and wherein the lower cone is disposed about the mandrel, and wherein the lower cone is operatively associated with the elastomer.
