Abstract

The illustrative embodiment of the present invention provides a method of recording object associations using a location system. Object locations are determined based on signals generated from object identifiers linked to the objects and forwarded to an electronic device interfaced with a network. The origin of the signal is calculated by a location determining module based on a variety of factors including the known position of the receivers receiving the signal, the historical recorded position of the object, the characteristics of the receivers receiving the signal (i.e. the range), the strength of the received signal, the type of signal, and whether or not the signal was repeated. Once the location of the object has been determined, the locating determining module consults a database to determine associations between the located object and other objects or specified locations based on the other objects proximity to the located object. Once an association is determined, it is stored and the duration of the association is subsequently recorded. The data from the identified associations may then be leveraged in a number of ways as input data for a variety of applications, such as billing software, equipment utilization software, asset management software, and automatic event generation software.
