Abstract:
1. A method for electronic monitoring of activities in a tracking environment comprising: selecting a schedule including a plurality of events; collecting activity data in substantially teal time from the tracking environment, wherein the activity data includes proximity information concerning first and second energy signal identification badges, wherein the first badge is a normally off energy transceiver, wherein the first badge is activated when the first badge detects trigger signals transmitted at a minimum power level and from within a predetermined radius of the first badge, wherein the second badge generates the trigger signals for activating the first badge, and wherein the first badge generates activity data signals representative of a proximity condition between the first and second badges when the first badge is activated by the trigger signals from the second badge; evaluating the activity data in substantially real time to determine whether at least one of the events of the schedule has been performed, wherein the evaluating includes using the proximity information; updating a status record of the schedule in substantially real time based on the evaluation of the activity data; and making the status record of the schedule and the activity data available for access in real time.
