The present invention is a transparent conductor containing electrically conductive particles, a binder, and an ultraviolet absorber. The present invention includes a toothpaste dispenser body forming a radius resiliently and integrally securing together a substantially flat first coextensive member and a substantially flat second coextensive member. The second bearing portion assumes a generally C-like shape and opens in a second direction opposite the first direction. One implementation of the invention searches for the locations in the model between each pair of radio receivers where their signal strength is different by an observed amount.
