Abstract

A method for alerting a user of a first portable communications assembly that another user of a second portable communications assembly is within a predetermined distance includes the step of receiving a distance signal transmitted by the transmitter in the second portable communications assembly. A distance between the first and second portable communications assemblies based on the distance signal is calculated based on the strength of the distance signal or based on a time stamp embedded in the distance signal. An alert is emitted when the distance calculated between the first and second portable communications assemblies is less than the predetermined distance.

Claims (8)

1. A method for communicating between a plurality of portable communications assemblies, the method comprising the steps of:

identifying each of the plurality of portable communications assemblies;

transmitting communications from each of the plurality of portable communications assemblies to another of the plurality of portable communication assemblies by communicating directly therebetween;

receiving communications from one of the plurality of portable communications assemblies via a transceiver selected from another of the plurality of portable communication assemblies;

identifying a portion of the plurality of portable communications assemblies that is sending communication indicating a conditional threshold is met;

transmitting threshold limit communication to the portion of the plurality of portable communications assemblies regarding the threshold limit status, wherein the threshold limit communication relates to the proximate location of the portion of the plurality of portable communications assemblies to the one of the plurality of portable communications assemblies; and

producing an event report entry for each of the threshold limit communications transmitted indicating the conditional threshold was met.

2. A method as set forth in claim 1 including the step of storing the event report entry until it is downloaded to a central processing unit.
