Abstract:
Indoor positioning systems and methods including a reverse-beacon for location determination and presence sensing technology. The reverse-beacon is any device comprising a transceiver and a computer operating with system nodes and will generally be in the form of a smartphone or other mobile computer. The systems and methods utilize wireless signals of any device that adheres to a general-purpose communication protocol, such as Bluetooth™ and Wi-Fi, to provide location-based services such as location determination and acting as a ground-truth field for presence sensing systems. The systems and methods operate by passively licensing to wireless communications that take place during the ordinarily course of operation of a wireless network irrespective of the presence of the reverse-beacon.

Claim (Index 18):
A system for locating a reverse-beacon in a detection field comprising:\n a plurality of system nodes deployed to form a detection field; a reverse-beacon comprising a transceiver, a computer, and a non-volatile computer-readable storage medium having program instructions thereon which, when executed by said computer, cause said reverse-beacon to perform the steps of:\n receiving first system node signals from a first system node in said plurality of system nodes at said transceiver; \n converting said first system node signals to a historical dataset including a first system node identifier and a first system node distance associated with said first system node; \n repeating said receiving and said converting a plurality of times to form a plurality of said historical datasets; \n determining a location of said reverse-beacon within said detection field, based upon comparing each of said historical datasets in said plurality of historical datasets to calculate a location of said reverse-beacon relative to said first system node and within said detection field.
