1. A system for determining a location of an object, comprising:
- a substrate including a sequence of bits, wherein the sequence of bits is physically arranged on the substrate and the sequence of bits includes overlapping subsequences of bits, and wherein each subsequence of bits is unique for each location along the substrate;
an object at a particular location along the substrate, wherein the substrate is a coaxial cable, wherein the sequence of bits are formed as slits and no slits in the coaxial cable;
a sensor configured to detect the subsequence of bits at the particular location of the object; and
a decoder configured to associate the location of the subsequence of bits at the particular location with the object.

Abstract
A location of an object is determined by arranging a sequence of bits on a substrate. The sequence of bits includes subsequence of bits, and each subsequence of bits is unique for each location along the substrate. When the object is at a particular location along the substrate a sensor detects the subsequence of bits at the particular location, and a decoder associates the location of the subsequence at the particular location with the object. The substrate can be a leaky coaxial cable with slits or not, corresponding to the bits, or lane markings on a road.
