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.

18. A method for determining a location an object, comprising a processor for performing steps of the method, comprising the steps of:
-
arranging a sequence of bits on a substrate, wherein the sequence of bits includes overlapping subsequences of bits and each subsequence of bits is unique for each location along the substrate; sensing the subsequence of bits at a particular location of an object; and decoding the location of the subsequence of bits at the particular location; and associating the location of the subsequence of bits at the particular location with the object.
