The security tracker can accurately track every firefighter inside a burning building

In the process of extinguishing the fire is very important to keep track of the location of all participating firefighters in the interests of their safety. To do this, the team of researchers of Karlsruhe Institute of Technology (Germany) develops compact, wearable device the size of a few centimeters, which is mounted on the Shoe.

When a fireman is going to enter the building, the common information system records its position via GPS. Unfortunately, the GPS inside buildings is very unstable, which compensates for the new device. It is at the entrance to the building, and then starts to track the direction and distance traveled from the last point whence the GPS signal.

The main elements of the device – the accelerometer and gyroscope, which measures the speed and orientation in space. Measurement accuracy is enhanced by the ability to break each step into smaller pieces. For example, jump leg off the surface and, having made a forward movement, again the surface is several sequential motor phases.

All information is transmitted wirelessly to a computer located outside of the building. If one of the firefighters will not be able to leave the building or stay there for unknown reasons, his colleagues will know its exact location.

Scientists are also developing a wearable device that will be paired with the mentioned tracker. It will be equipped with an infrared camera to create a 3D model of the space that surrounds the fire. As a result, those who are in charge of extinguishing the fire will have a clearer idea about what’s going on inside the building.

Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes. […]

Looks like a screwdriver of the XXI century

What similar high-tech screwdriver advanced Italian production? And it is similar to the Kinetic device Driver. Kinetic Driver designed by the Italian designer Giacomo Di […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]

Some homemade masks turned out to be more dangerous than no

Despite the fact that the industry has recovered from the shock of the first days of the pandemic COVID-19 and now produces enough facial masks of different types, most people in the world due to various reasons use homemade versions. Everyone understands that they are less effective than professional medical model, but the question is: […]
