Magnetic-based tracking system

A magnetic-based tracking system, said system comprising:

• a vehicle having wheels on a surface of a substrate that the vehicle travels over;
• a plurality of magnetic stripes on the substrate, wherein some of the magnetic stripes are spaced a first distance and others of the magnetic stripes are spaced a second distance, whereby the first distance represents a first logic value and the second distance represents a second logic value, and the first distance is greater than the second distance;
• and
• one of the wheels of the vehicle comprises
• a digital processor,
• a rotation sensor coupled to the digital processor,
• a magnetic sensor coupled to the digital processor,
• a non-volatile memory coupled to the digital processor,
• a real-time clock coupled to the digital processor,
• a wireless communications device coupled to the digital processor, and
• a power source;
• wherein
• when the magnetic sensor detects a magnetic stripe the digital processor is notified and the rotation sensor provides a wheel rotation value until a next magnetic stripe is detected,
• a first logic value is determined when the wheel rotation value is greater than a predetermined rotation value and a second logic value is determined when the wheel rotation value is not greater than the predetermined rotation value,
• the first or second logic value is stored;
• and
• detection of another magnetic stripe and another next magnetic stripe continues for determining first or second logic values until the stored first and/or second logic values complete a location word, wherein the location word and an associated time stamp are stored in the non-volatile memory.
