The new technology developed by VTT, Technical Research Centre of Finland makes it possible to identify the user based on her or his physical movements such as walking style. This feature prevents unauthorised use of portable devices such as laptops or mobile phones. In the future, credit cards may also verify users identify based on their physical movements before approval of payment transactions.
For the user the new identification system offers the advantages of increased security and reduction of risk in situations where a portable computer, mobile phone or other digital device has ended up in the wrong hands because of loss or theft. The device will become non-usable in the wrong hands. For example, the identity of a mobile phone user can be verified before the phone can be used for banking transactions. Compared with passwords and traditional bioidentification, the new method is simple: confirmation of identity takes place as a background process without any need for users intervention.
A device is equipped with sensors that measure certain characteristics of the user’s gait. When the device is used for the first time, these measurements are saved in its memory. In normal use the device continuously measures the user’s gait and compares these measurements with the values in its memory. If they are sufficiently identical, the device identifies and approves the user. If the values differ, standard password-based identification is available.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
