Abstract
Disclosed embodiments relate, generally, to beacon systems where a locator beacon is used as a marker for a location of interest, and improving false positive immunity in such beacon systems. Confiner beacons are included in such beacon systems to confine a triggering area for triggering a location indication for a location of interest marked by a locator beacon. In other embodiments, arbitrarily shaped triggering areas are defined using confiner beacons. In other embodiments, errant locator signals are identified and handled (e.g., ignored).
Claims32
A device, comprising:
- a communication equipment configured to receive wireless signals;
- and
- a localization unit configured to:
- associate one or more locator signals and one or more confiner signals with a three-dimensional (3D) space of interest;
- define a boundary of the 3D space of interest at least partially responsive to the one or more confiner signals;
- suppress a location indication at least partially responsive to observing an indication of a presence of the device outside the 3D space of interest;
- and
- initiate the location indication at least partially responsive to observing an indication of the presence of the device within the 3D space of interest.
A localization method, comprising:
- associating one or more locator signals and one or more confiner signals with a three-dimensional (3D) space of interest;
- defining a boundary of the 3D space of interest responsive to one or more confiner signals;
- suppressing a location indication responsive to observing a presence of a receiver outside the 3D space of interest;
- and
- triggering the location indication responsive to observing the presence of the receiver within the 3D space of interest.
A wireless beacon system, comprising:
- a first wireless transmitter configured to generate wireless signals indicative of a three-dimensional (3D) space of interest;
- and
- second wireless transmitters configured to generate wireless signals indicative of 3D spaces not-of-interest,
- wherein the first wireless transmitter is arranged at a first location within a desired boundary defining the 3D space of interest, and
- wherein the second wireless transmitters are arranged at second locations selected outside the desired boundary defining the 3D space of interest such that respective desired boundaries defining the 3D spaces not-of-interest at least partially define the desired boundary of the 3D space of interest.
