Parking sensors capable of determining direction and speed of vehicle entering or leaving a parking lot using magnetic signature recognition
First Claim
1. A system comprising:
- a single sensor comprising a magnetometer configured to generate a magnetic signature of a vehicle as it drives across the single sensor;
a computing device configured to perform an analysis of the magnetic signature of the vehicle as received from the magnetometer, wherein the analysis includes comparing the magnetic signature of the vehicle as received from the magnetometer to known magnetic signatures of known vehicle types to thereby determine a direction of travel of the vehicle relative to the single sensor based upon the comparison,wherein each known vehicle type has a plurality of known magnetic signatures associated with each known vehicle type, wherein each known magnetic signature associated with each known vehicle type is a magnetic signature of that vehicle type captured during driving of a vehicle of the vehicle type over the sensor apparatus from a different direction or different vehicle orientation.

Abstract
A parking inventory management system includes a sensor apparatus with at least one magnetometer configured to generate a magnetic signature of a vehicle as it drives across the sensor apparatus. A computing device performs an analysis of the magnetic signature of the vehicle as received from the at least one magnetometer, the analysis including at least comparing the magnetic signature of the vehicle as received from the at least one magnetometer to known magnetic signatures of known vehicles. The computing device performs the analysis of the magnetic signature of the vehicle by comparing the magnetic signature of the vehicle to each of the known magnetic signatures of known vehicles to thereby determine a direction of travel of the vehicle based upon the comparison.

13. A method of determining direction of a vehicle, the method comprising:
-
acquiring a respective magnetic signature of the vehicle as it drives past a single magnetometer; performing an analysis of the magnetic signature of the vehicle as received from the single magnetometer to determine at least one of a speed of the vehicle, a direction of travel of the vehicle, and a position of the vehicle with respect to the single magnetometer, wherein the analysis of the magnetic signature of the vehicle is performed by comparing the magnetic signature of the vehicle to known magnetic signatures of known vehicle types, wherein each known vehicle type has a plurality of known magnetic signatures associated with each known vehicle type, wherein each known magnetic signature associated with each known vehicle type is a magnetic signature of that vehicle type captured during driving of a vehicle of the vehicle type past the single magnetometer from a different direction or different vehicle orientation. - View Dependent Claims (14, 15, 16, 17, 18)
