Abstract:
1. A system for associating a change in a state or location of an asset to an event trigger within a monitored environment, comprising: a plurality of assets; a tag transmitter positioned on each asset and configured to transmit a wireless RF signal based on an event trigger based on one of at least the change in the state of the asset on which the tag transmitter is positioned and the change in the location of the asset; a plurality of spaced apart access points positioned at known locations within the monitored environment and configured to receive the wireless RF signal transmitted from the tag transmitter; and a processor operatively connected to said access points, wherein said processor is configured to collect possible candidates as assets associated with the event trigger and configured to assign a numerical score to each candidate to determine which asset is best associated with the event trigger, wherein the numerical score of each candidate is based upon how well each candidate matches an event associated with the event trigger according to at least one rule configured to assess each candidate with the event.
