Emergencies

There are many potential uses for augmented reality (AR) glasses, such as real-time captioning for the deaf, training military pilots, and providing runners with virtual partners. Now, they may also help Japanese emergency medical technicians (EMTs) save lives.

Sesame Solar announced this week what it calls the world's first 100-percent renewable mobile nanogrid. Powered by a wing-like solar panel spread and green hydrogen, the modular nanogrid brings weeks of autonomous electricity where it's most needed.

When someone is suffering from a deep stab wound, it's important to apply pressure within that wound. A new student-designed device is intended to let first responders do just that, potentially saving lives that might otherwise be lost.

New York-based medical transport non-profit Hatzolah Air has placed a preorder for four of Urban Aeronautics' CityHawk VTOL aircraft for emergency medical service (EMS) applications within urban environments.

Because bikes can skirt around traffic jams – and park just about anywhere – they're often faster than cars on congested city streets. That's why bicycle couriers exist, and it's also why the Emergency Bikes ebike ambulance was created.

A feasibility study modeled on the VoloCity multirotor electric air taxi has concluded that electric vertical take-off and landing aircraft would benefit emergency air rescue services. Now the project is looking to begin operational testing in 2023.

Although "air ambulance" helicopters are life-savers, they typically can't land in the middle of crowded city streets. The CityHawk aircraft conceivably could, though, which is why it's now being developed with emergency medical response in mind.

While it's a good idea for people with upstairs bedrooms to have a collapsible fire escape ladder handy, quickly finding and deploying the thing could be difficult in a smoke-filled home. That's where the Rescue Ready Retrofit is designed to come in.

Last year, Arcimoto revealed a special version of its battery-electric three-wheeler designed for first responders. The company inked an agreement with the Eugene Springfield Fire Department to test the vehicles, and now that pilot program has begun.

In search of a new niche market, startup Jump Aero wants to use eVTOL aircraft to ferry first responders to emergencies at speeds of up to 200 mph. The goal is not only to deliver responders quickly, but also to allow them to land on suburban roads.

It can certainly be a rattling experience for drivers, when they suddenly realize that the sound of an emergency vehicle's siren is coming from someplace nearby. Cerence's EVD system is designed to help, by hearing sirens before drivers do.

When first responders are tending to accident victims with lacerations, one of their primary goals is to control the bleeding. It may someday be possible for them to do so more effectively than ever, by injecting patients with a magnetic fluid.
