RF beacon proximity determination enhancement
First Claim
1. A system comprising:
- a communications device for periodically transmitting a radio frequency signal, wherein the periodically transmitted radio frequency signal includes data;
a receiver for detecting the periodically transmitted radio frequency signal, the detecting including measuring signal strength of the periodically transmitted radio frequency signal, the detecting including using the measured signal strength to provide a first estimate of the receiver'"'"'s distance from the communications device;
the communications device including at least one location sensor for detecting distance information for use in confirming the first estimate, wherein the data includes the distance information detected by the at least one location sensor, wherein the distance information relates to distance between the communications device and the receiver;
the receiver configured to use the distance information to confirm the first estimate, the confirming the first estimate comprising the distance information indicating a first state,the receiver configured to perform a function when the first estimate meets at least one criterion and when the distance information indicates the first state.

Abstract
A system is described herein that comprises a communications device periodically transmitting a radio frequency signal, wherein the periodically transmitted signal includes data. The system includes a receiver detecting the periodically transmitted signal, the detecting including measuring strength of the periodically transmitted signal, the detecting including using the signal strength to provide a first estimate of the receiver'"'"'s distance from the communications device. The system includes the communications device comprising at least one location sensor for determining an additional distance indication, wherein the data includes the additional distance indication. The system includes the receiver performing a function when the first estimate meets at least one criterion and when the additional distance indication indicates a first state.
