An increasing number of new auto buyers choose diesel engines. For asthmatics and those with allergies this is very unfortunate. Particles in diesel exhaust can both worsen and trigger allergic reactions.
"Tough, raw and macho". Such is the advertising for many new off-road vehicles on the market today. They can drive in the mud as well as on pavement and they most often use diesel. It is no longer the “macho boys” that drive these vehicles – now they have also become very popular as family vehicles. The statistics for new autos purchased in February show that almost three out of ten autos that were sold in Norway are fuelled by diesel. In the same period last year, two out of ten autos had diesel engines. But even though the auto industry has successfully made diesel engines cleaner, by among other things installing filters in newer autos, the problem is far from solved. Around 90 percent of heavy traffic in Norway is also fuelled by diesel. And all ships and some trains still have diesel engines.
Great health problem

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
