CORRECTING AND/OR IMPROVING LOCATION INFORMATION USING OBJECT LOCATION HISTORY, TOPOLOGY, AND/OR OTHER INFORMATION
First Claim
1. A computer-implemented method for refining a zone location of a tracked object, the computer-implemented method comprising:
- a) accepting, by a computer system including at least one computer, first location information derived from a first location technology;
b) generating, by the computer system, a set of at least two candidate location zones using the first location, topology information and an accuracy range for the first location technology;
c) for each of the at least two candidate location zones,1) establishing, by the computer system, a path from a previous location zone to the given candidate location zone, and2) storing, by the computer system and in association with the candidate zone, any location zones on the path;
d) applying, by the computer system, at least one of (A) path-based candidate location zone elimination to each of the at least two candidate location zones, and (B) object-physics-based candidate location zone elimination to each of the at least two candidate location zones, to generate a refined set of at least one candidate location zone; and
e) storing, by the computer system, the refined set of at least one candidate location zone in association with the tracked object.

Abstract
A zone location of a tracked object may be refined by (a) accepting first location information derived from a first location technology, (b) generating a set of at least two candidate location zones using the first location, topology information and an accuracy range for the first location technology, (c) for each of the at least two candidate location zones, (1) establishing a path from a previous location zone to the given candidate location zone, and (2) storing, by the computer system and in association with the candidate zone, any location zones on the path, and (d) applying at least one of (A) path-based candidate location zone elimination to each of the at least two candidate location zones, and (B) object-physics-based candidate location zone elimination to each of the at least two candidate location zones, to generate a refined set of at least one candidate location zone.

13. Apparatus for refining a zone location of a tracked object, the apparatus comprising:
-
a) at least one processor; and b) at least one storage device storing processor-executable program instructions which, when executed by the at least one processor, perform a method of, 1) accepting first location information derived from a first location technology, 2) generating a set of at least two candidate location zones using the first location, topology information and an accuracy range for the first location technology, 3) for each of the at least two candidate location zones, establishing a path from a previous location zone to the given candidate location zone, and storing, in association with the candidate zone, any location zones on the path, 4) applying at least one of (A) path-based candidate location zone elimination to each of the at least two candidate location zones, and (B) object-physics-based candidate location zone elimination to each of the at least two candidate location zones, to generate a refined set of at least one candidate location zone, and 5) storing the refined set of at least one candidate location zone in association with the tracked object.
