SYSTEMS, METHODS, AND APPARATUS TO DETERMINE PHYSICAL LOCATION AND ROUTING WITHIN A FIELD OF LOW POWER BEACONS
First Claim
1. A position location system, comprising:
- a receiver to receive a plurality of broadcast signals, each of the plurality of received signals associated with an originating one of a plurality of beacons;
a processor that;
determines an initial receiver location relative to locations of at least some of the plurality of beacons;
determines a vector quantity associated with each of the plurality of received broadcast signals to provide a respective plurality of vector quantities; and
determines an updated receiver location based on summing the plurality of vector quantities; and
generates an output indicative of the updated receiver location.

Abstract
A non-time of flight or time of arrival position location system for accurate determination of a user'"'"'s location in an enclosed, indoor, or covered environment can include a number of beacons mounted in an arrangement within the environment. Each of the beacons is mounted in a known location and transmits a broadcast signal containing a unique identifier that identifies the originating beacon. A handheld electronic device including a receiver and a communicably coupled processor can receive broadcast signals from at least some of the number of beacons, iteratively determine a vector quantity corresponding to each of the received signals, and sum the resultant vector quantities to determine an updated position. The iterative process can be repeated until consecutive iterations yield an updated position that falls within a defined threshold.

17. A position location system of a handheld electronic device, comprising:
-
a receiver to receive a plurality of broadcast signals, wherein one or more of the plurality of received signals contain data identifying at least one of a plurality of beacons; a processor communicably coupled to the receiver, wherein the processor; receives user input indicative of a desired object location of a desired object to which the user would like to travel; determines preferred routing to the desired object location of the desired object inputted by the user based on the plurality of broadcast signals; outputs guidance to the desired object location using the determined preferred routing; determines updated locations of the user by periodically or intermittently updating the location of the user while the user is attempting to follow the determined preferred routing; determine updated routing based on the updated location of the user; and identify when the location of the handheld electronic device is within a defined distance of the location of the desired object. - View Dependent Claims (18, 19, 20)
