Abstract:
1. A non-transitory computer readable medium containing program instructions representing software executable in a central monitoring system comprising a computer system including a microprocessor memory media and storage media and connected to a network, which instructions, when executed by the computer system, cause the computer system to perform method steps for monitoring the status of multiple persons in a group based on distance between a communications device associated with each person and one of multiple vehicles, each person in the group associated with one of the vehicles, the status indicative as to whether each person in the group has moved away from an associated vehicle or returned thereto, wherein each communications device is a first device in a pair of first and second devices, the first devices being carried by persons in the group while the second devices are each positioned at one of the associated vehicles, the method comprising: receiving, by a central monitoring system comprising a processor, digital data from at least one member in each pair of devices in communication across a network with the processor of the central monitoring system, and processing the digital data received from the at least one member in each pair of devices, by: assimilating location status information from the data received from at least one member in each pair of devices, wherein the data is based on a distance between the devices in each pair derived from strength of a RF signal transmitted from one device in the pair toward the other device in the pair, the location status information indicative of persons in the group being in a first status when the person associated with the communications device in the pair has moved beyond a predetermined range of distance from the vehicle; and outputting updated location status information to a display screen to provide notification when a person in the group is in the first status.
