Determining a location or position using information from multiple location and positioning technologies and applications using such a determined location or position
First Claim
1. A machine-implemented method for determining a location using location information from multiple location systems of different types, the machine-implemented method comprising:
- a) accepting multiple location information corresponding to various different location and positioning systems for one or more devices;
b) estimating and recording the accuracy of the received location information;
c) interpreting the received location information using a unified model;
d) combining the location information pieces with contextual information based on an application;
e) accepting requirements from the application for further refinement of location and position; and
f) directing and configuring the various location and positioning systems to carry out further actions to locate the desired target object.

Abstract
A location may be determined by accepting location information from at least two sources using at least two location technologies, for each set of location information from each source, adjusting the location information using at least one of (A) confidence in the source, (B) error range of the source, (C) an error model for the source, and (D) application-specific context information, and combining adjusted locations to generate a final location these location technologies assume a degree of cooperation. The location technologies may include a combination of a “tag” that is placed on the object to be tracked, and one or more receivers/transmitters that work in concert with the tag to locate the object.
