Better technology and modern materials increase the traffic safety and save human life. But they pose totally new challenges for the emergency personnel at the accident site. Because today, tools like hydraulic rescue cutters more and more often reach their limits. A mobile laser unit for rescue missions shall solve this problem. The Laser Zentrum Hannover e.V. (LZH), six project partners and eight associated partners have teamed up to develop this system.
In the past 25 years, the number of road traffic deaths has been drastically reduced, and the number of severely injured persons decreased significantly, too. Among others, the declining figures are due to improved passive safety. The use of high-tensile steel and composite materials adds to this.
Conventional rescue systems more and more often reach their limits with modern materials.

Time as a decisive factor
The higher vehicle stability achieved by using these materials, however, becomes a problem in the event of an accident. Because the available rescue systems, such as power, plasma or hydraulic rescue cutters require a lot of time to cut the car body, or they even fail in individual cases. Time, however, is crucial during a rescue mission. The faster a person is freed, the higher the chances to survive.
Using the laser at the accident site
This is where the project comes in: A compact laser unit shall be developed that can be used when conventional rescue tools reach their limits. With this system it shall be possible to cut modern materials in a short time, or to broach them so that they can be cut faster with conventional tools.
Moreover, it shall be investigated within the scope of the project how the safe use of the laser at the accident site can be guaranteed. Here, it is also being checked, for example, which shut-off devices are required for the system. In addition, the scientists evaluate which measures must be taken to protect the rescue team, the accident victim and uninvolved third parties. This includes curtains, mats and protection glasses.
The partners from many different sectors ensure that all relevant aspects are considered. Project partners of the LZH are: Coherent (Deutschland) GmbH, SGE Spezialgeräteentwicklung GmbH, WEBER-HYDRAULIK GmbH, eifeler Lasertechnik GmbH, LASERVISION GmbH & Co. KG and Stadt Dortmund – Institut für Feuerwehr- und Rettungstechnologie.
Associated project partners are: Bundesanstalt für Arbeitsschutz und -medizin, Berufsgenossenschaft Energie Textil Elektro Medienerzeugnisse, DB Fahrzeuginstandhaltung GmbH, DEKRA Automobil GmbH, GuS – Präzision in Kunststoff, Glas und Optik GmbH & Co. KG, Bundesanstalt Technisches Hilfswerk, Unfallkasse NRW and Volkswagen AG.
The project is being sponsored by the German Federal Ministry of Education and Research (BMBF) within the scope of the program “Civil safety – innovative rescue and safety systems” until October 2019.

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.
Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...
For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.
Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...
An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".
The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
An interdisciplinary research team at the Technical University of Munich (TUM) has built platinum nanoparticles for catalysis in fuel cells: The new size-optimized catalysts are twice as good as the best process commercially available today.
Fuel cells may well replace batteries as the power source for electric cars. They consume hydrogen, a gas which could be produced for example using surplus...
