Improved speed, precision and flexibility — it is important to take advantage of every possible opportunity in optimizing production. To this end, researchers at the Fraunhofer Institute for Material and Beam Technology IWS have developed SURFinpro, a solution that uses artificial intelligence and optical measurement technology to detect, classify and visualize defects in real time, and report them to the plant carrying out the production. The experts will be presenting their system from June 27 to 30, 2023, at Laser World of Photonics, joint Fraunhofer Booth 441 in Hall A3.

How do you decide whether a pedestrian needs to wait or it’s safe to cross the road in front of a car? In today’s world, drivers and pedestrians simply exchange a brief eye contact or small hand gestures to express their intentions to one another. But how will future autonomous cars communicate? Researchers involved in the MaMeK project are seeking to answer this question. They will present their findings at the LASER World of PHOTONICS trade fair in Munich from June 27 to 30 (Booth 415, Hall A2).

Due to the high energy consumption of melting and holding furnaces, the price of the energy source used represents a significant cost factor in the production of castings. The price of electricity fluctuates significantly over the course of the day. This can be explained, for example, by the varying utilization of the power grid or the volatile feed-in of energy from renewable resources. As a result, companies should design their energy consumption flexibly to operate their production processes as cost-efficiently as possible. Together with its partners, the Fraunhofer Institute for Manufacturing Engineering and Automation IPA is developing a bivalent furnace that enables dynamic switching between gas and electricity. This will ensure that operation is flexible in terms of the type of energy deployed, allowing energy to be used when it is most cost-efficient.

Lightweight design is essential for sustainable mobility. Drive shafts made of carbon-fiber-reinforced plastics (CFRP) with a thermosetting matrix, for example, can reduce climate-damaging emissions. Nevertheless, the lightweight design and resource-saving potential of these shafts has not been completely realized yet. Together with partners, researchers at the Fraunhofer Institute for Applied Polymer Research IAP are developing a new, very lightweight drive and side shaft system for cars and trucks whose matrix consists of thermoplastic materials. These materials can be recycled and have an additional weight advantage.

Silicon carbide is a popular industrial material for many applications. The extremely hard, heat-resistant material is used for refractory components and semiconductors, for instance. But its production is energy-intensive and emits a lot of carbon dioxide, as well as producing large amounts of by-products and waste products. Researchers at Fraunhofer Institute for Ceramic Technologies and Systems IKTS have developed RECOSiC©, an especially environmentally friendly recycling process that turns these by-products and waste products back into high-quality silicon carbide. This new process improves yields and also reduces the dependency on suppliers of raw materials.

Developing an audio device that offers optimum sound experience to all people is not easy. The great challenge is that each person has their own listening preferences. For this reason, the Oldenburg Branch for Hearing, Speech and Audio Technology HSA of the Fraunhofer Institute for Digital Media Technology IDMT has developed adaptive algorithms as well as intuitive methods for adjusting personal sound. Together with a customer, this technology has now been successfully integrated in headphones as well.

We need to lower our CO2 emissions systematically if we want to achieve our climate targets. Insulating buildings is a key part of this. Researchers from the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT in Oberhausen have been working in collaboration with PROCERAM GmbH & Co. KG to develop a sustainable, affordable mineral-based insulation material that is far more effective than options such as polystyrene. This material can achieve the same level of insulation as polystyrene with only half the layer thickness. Three members of the development team are being awarded the Joseph von Fraunhofer Prize 2023 for this achievement.

Water is becoming increasingly scarce. In the future, innovative satellite technology will ensure that plants are given only as much water as they need, leading to a more sustainable use of this essential resource. A prototype of the technology, LisR, has already been tested on the International Space Station (ISS). A team of researchers from the Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut, EMI, the Fraunhofer Institute for Applied Optics and Precision Engineering IOF and two spin-offs, constellr GmbH and SPACEOPTIX GmbH, has received the Fraunhofer Prize for Human- and Environment-Centered Technology for this development.

Prof. Holger Hanselka will be the 11th president of the Fraunhofer-Gesellschaft. The senate of the Fraunhofer-Gesellschaft unanimously elected the current president of the Karlsruhe Institute of Technology (KIT) at its meeting in Dresden today. Hanselka succeeds Prof. Reimund Neugebauer, who resigned from his post by mutual agreement today after almost eleven years at the helm of the Fraunhofer-Gesellschaft.

Whether streaming music and movies, watching TV or in the car: The MPEG-H Audio system makes it possible to fully immerse yourself in soundscapes and adjust them to your own preferences. Three researchers from the Fraunhofer Institute for Integrated Circuits IIS — representing a large team — are being awarded the Joseph von Fraunhofer Prize 2023 for this development.
