System and method for situational awareness
First Claim
1. A computer-implemented method for monitoring whether at least one person in a group of persons has been away from a vehicle for longer than a predetermined time period, comprising:
- with a computer system positioned remote from the vehicle, providing a network connection between a device associated with a person in the group and the computer system or between a vehicle and the computer system;
initiating the monitoring for the person upon detection of a proximity association between the person and the vehicle by receiving into the computer system, via the network, first digital information indicating a proximity association between the person and the vehicle wherein the person is occupying a first relatively close position with respect to the vehicle;
receiving into the computer system, via the network, further digital information, derived from rf signal strength or detection, indicating whether the person has moved farther away from the vehicle than the first relatively close position;
initiating a timer function if the information the computer system receives indicates the person has moved farther away from the associated vehicle than the first relatively close position;
periodically receiving, into the computer system, updated information, also derived from rf signal strength or detection, indicating whether the person remains farther away from the vehicle than the first relatively close position; and
sending a notification from the computer system to at least one device associated with another person in the group if, after a predefined time period determined with the timer function, it is determined that the person remains farther away from the associated vehicle than the first relatively close position, the notification indicating that the person has remained farther away from the vehicle than the first relatively close position during the predefined time period.

Abstract
A method providing persons in a group information about the whereabouts of others in the group, including whether persons in the group have moved away from an associated vehicle. The method includes receiving information into a computer system derived from measured rf signal strength sent in digital form from one or more portable devices. The information indicates whether any of the persons has moved from a first relatively close position with respect to an associated vehicle and farther away from the associated vehicle than the first position. A timer function may be initiated if the received information indicates that a first person has moved farther away from the associated vehicle than the first position. Updated information may be received, indicating whether the first person remains farther away from, or has moved to a position at least as close as the first relatively close position is to, the associated vehicle.

11. A computer-implemented method for monitoring whether a person in a group is away from an associated vehicle, comprising:
-
receiving, into a computer system positioned remote from the vehicle, digital information indicating the person is occupying a first relatively close position with respect to the vehicle; automatically receiving into the computer system further digital information, based on rf signal strength or detection, via a network, indicating whether the person has moved to a second position farther away from the associated vehicle than the relatively close first position; and sending a notification from the computer system to at least one device associated with another in the group, based on received information, that the person is farther away from the vehicle than the first relatively close position is from the vehicle. - View Dependent Claims (12, 13, 14)

15. A method for providing persons in a group status information and information about the whereabouts of other persons in the group, including whether persons in the group have individually moved away from a vehicle in an identified group of vehicles or returned to the vehicle, the method comprising:
-
using a computer system positioned remote from the identified vehicle, periodically receiving into the computer system information based on rf signal strength or rf signal detection automatically sent from one or more portable devices to the computer system in digital form via a cellular network, each said portable device positioned remote from the computer system; processing said information to determine whether an individual in the group of persons has moved from a first relatively close position with respect to the vehicle to a second position farther away from the vehicle than the first relatively close position; and communicating to persons in the group status information based on a determination of whether the individual has moved from the first relatively close position with respect to the vehicle to the second position farther away from the vehicle than the first relatively close position. - View Dependent Claims (16, 17, 18, 19, 20)
