Inspired by Paul Revere’s “one if by land, two if by sea” ride to alert the Colonists to the arrival of the British and mercenary forces during our Revolutionary war: "If the British march by land or sea from the town to-night, hang a lantern aloft in the belfry arch of the North Church tower as a signal light,-- one if by land, and two if by sea; And I on the opposite shore will be, Ready to ride and spread the alarm through every Middlesex village and farm, For the country folk to be up and to arm." Router – switch multicast radius will be adjustable -- increase / decrease with audible tones and vibratory levels based on business logic / military mission thread logic according to threshold rules visually displayed as concentric color band expansion / collapse based on DHS and other five level color / audible advisory schemes. Alert, evacuation, alternate routing of transportation assets, medical triage will then adjust & filter by business logic / mission threads by zones (e.g., a wave that travels 30 miles inland with a casualty count > 100,000). The Heart Beacon is the adapatation of the Army Communication Electronic Command's Greatest Invention that has been in use since before and during the capture of Saddam Hussein and was enhanced for satellite broadcast during the Balkan Conflict. The template system & greatest invention developed by DARPA by the Army makes use of opportunities in time to gather more state meta data from networked devices to aid "spontaneous integration" of disparate users and groups and "maneuver the network" making changes to router subnets supporting group operations in ways not done in the commercial first response sector since the commercial / public first response sector does not make use of the additional opportunities in time (heart beacon) to harvest state meta data). The template system developed by the military to support network centric operations was adapted to DHS handhelds prior to 2004 when DHS when live on this procedure supporting its blackberry devices. The point being made is if military / commercial groups are truly going to collaborate during disasters, they might consider using the same procedures and the same fundamental network building blocks currently applied DIFFERENTLY -- including the financial systems (SWIFT protocol employs heartbeat messages).
