Siemens is developing a system that helps blind and visually impaired people walk safely through cities.
In cooperation with the Technical University of Braunschweig and several partners, Siemens is working on a comprehensive assistance system for visually impaired people. The system is the result of a research project titled InMoBS. Among other things, the solution relies on the data transmitted between the traffic infrastructure and blind people's mobile devices.
Critical situations occur at intersections, for example. Although walk signals usually emit a beeping sound to inform visually impaired people, but they don't know how long the light is green or where exactly it is safe to walk. To provide such information, Siemens enabled smartphones for its car2x technology, which is used to transmit data between cars and traffic infrastructures.
For their walks, many blind people are already using barrier-free smartphone apps that let them navigate through cities with the help of GPS data and digital maps. The InMoBS project uses this technology for its assistance system. which provides its users with an online route planner that they can use at home to find the most barrier-free route to their destinations. The smartphone app emits vibration signals or verbally guides users along this route.
Traffic lights send their information to smartphones
Siemens has been working on technologies and standards for the communication between vehicles (car2car) and between vehicles and traffic infrastructure systems such as traffic lights and signs (car2x) for a number of years. The information is exchanged to improve the flow of traffic. As an example, a car's engine would only shut off automatically if the vehicle is notified that a traffic light would remain red for a certain amount of time.
This communication can also prevent traffic jams and accidents by having a car warn the vehicles behind it of bad road conditions, for example. Researchers at Siemens' global research department Corporate Technology are currently developing software and communications modules known as road side units for the wireless transmission of data between vehicles and traffic infrastructures.
As part of the InMoBS project, the researchers modified the communications software so that the light signal systems transmits their data via the WLAN standard commonly used for smartphones. Moreover, the information transmitted to smartphones is different to that for drivers. To ensure that all users can safely cross streets, for example, the app only emits a signal at the start of a "walk" phase. The infrastructure also transmits the intersection's layout to the app so that the user knows in which direction he or she has to cross the street.
The project partners recently unveiled a prototype of the assistant in Braunschweig. To create the assistant, the partners were able to use infrastructures that were installed in the city for the intelligent mobility application platform (AIM).

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
