Research on Existing Technology

What existing technology relates to our idea.

Smart watches for alerts

Connected to lifeline base (the lifeline base in our plan can be used to provide alerts instead).
Location tracking (works in emergencies).
Safe zone detection (could be used to alert wearer when they are in an undesirable location).
Press for emergency (would only be useful in specific scenarios).
Fall detector watches risk making wearers feel vulnerable and uncomfortable (can we make a watch associated with natural disasters invisible?).
At the moment, smart watch emergency functions are advertised as something which sends alerts, not receive them.

Electronic billboards

Oklahoma billboard (can be built in areas with a high chance of disasters, such as Oklahoma).
Shows magnitude.

Digital billboards for emergencies (can display relevant emergencies on screen).
Normal ads when circumstances are normal (blends in and doesn’t cause panic).
Special artwork designed for people speeding by (“safer for motorists than phone alerts”).
Backup generators are used during power outages.
“In case of hurricanes and other threats” implies they are versatile.
Satellite transmission from the management office (used by county officials, with enough leeway for A.I. to perform this).
Allows operators to activate region specific billboards (won’t cause unaffected locations to panic).
