New kinematics for customized, high-precision milling

Machining robot Flexmatik. Credit: Fraunhofer IFAM Manufacturers generally must offer high-quality products at low prices in order to remain competitive. Three Fraunhofer Institutes are therefore working on the next generation of industrial robots which will facilitate cost-effective production processes. The researchers are focusing on developing a new kinematics for milling lightweight materials, metals, and steels. The aim: achieving a production tolerance of just 0.1 millimeters all over the robot workspace starting with the very first component. More and more consumers…

Autonomous trucks for logistics centers

The truck drives independently to the loading ramp and waits until it is loaded. Credit: Fraunhofer IVI Spatially demarcated areas such as company premises are ideal test areas for autonomous driving: the vehicles do not require road registration, traffic is manageable, other people who use the road are informed and unauthorized individuals are not allowed access. In the collaborative project AutoTruck, Fraunhofer is cooperating with industry to develop technologies for autonomous trucks in logistics centers. The results also inform the…

A factory to go

A fully automated production line can be housed inside a 20-foot ISO container, which a heavy truck can transport quickly to wherever it is needed. Medical products can be manufactured in close proximity to a hospital, for instance. Fraunhofer researchers teamed up with partners to develop this mobile factory in the scope of CassaMobile, an…

A sentinel to watch over ocular pressure

Encapsulated sensor implant for measuring intraocular pressure. Credit: Fraunhofer IMS Fast, easy and uncomplicated – that sums up the EYEMATE sensor system developed jointly by Duisburg’s Fraunhofer Institute for Microelectronic Circuits and Systems IMS and Hanover’s Implandata Ophthalmic Products GmbH (Implandata). It is a real innovation in intraocular pressure measurement. EYEMATE is sure to make life easier for glaucoma patients and their eye doctors. This implant provides actionable information to optimize the therapy for patients afflicted with glaucoma. Out with…

Scanning in the fourth dimension

A 360 degree scan is completed using each round offset to enhance information capture. Credit: King Abdullah University of Science and Technology Three-dimensional (3-D) computed tomography is a widely used technology that visualizes an object’s external and internal structure by assembling a series of two-dimensional images taken sequentially across or around it. However, as anyone who has had a medical magnetic resonance imaging scan will recall, this type of 3-D reconstruction requires the subject to be motionless throughout the capture…

Unanswered Questions About the FIU Bridge Collapse

Last March 15, an innovatively-designed pedestrian bridge installed for less than a week suddenly collapsed onto a busy roadway in Florida International University, killing six people and injuring several more.  Although many bridges have been erected successfully using the technique known as accelerated bridge construction used for this bridge, this was one of the first times such a bridge failed during construction, and so both the engineering community as well as the public at large would like to know what…

Progressive Web Apps: The Biggest eCommerce Trend of Today

This web arena is constantly changing in the demand of something new. This is where progressive web apps are the biggest name in the competition among all the other players like websites and different kind of the web apps. The PWAs shower an extended level of navigation and user-friendliness that come attached with mobile apps. Digging deep, it is easy to access PWA with simple URLs that even work offline and easily indexed by the search engines. This is the…

Viruses are found to be the most common cause of meningitis but diagnosis is often delayed — ScienceDaily

The first major paper looking at the causes and consequences of meningitis in the UK has found that viruses are now the most common cause of meningitis in adults and a cause of substantial long-term ill health. The paper also found that the management of many patients with meningitis is sub-optimal. The study by researchers at the University of Liverpool’s Institute of Infection and Global Health, published in The Lancet Infectious Diseases, funded by Meningitis Research Foundation (MRF) and the…

Even low pollution levels can pose health risk — ScienceDaily

New research links outdoor air pollution — even at levels deemed safe — to an increased risk of diabetes globally, according to a study from Washington University School of Medicine in St. Louis and the Veterans Affairs (VA) St. Louis Health Care System. The findings raise the possibility that reducing pollution may lead to a drop in diabetes cases in heavily polluted countries such as India and less polluted ones such as the United States. Diabetes is one of the…

New form of ‘active matter’ driven by the dissolution of droplets of an ionic liquid — ScienceDaily

Researchers from Tokyo Metropolitan University have observed the formation of holes that move by themselves in droplets of ionic liquids (IL) sitting inside water-ethanol mixtures. This curious, complex phenomenon is driven by an interplay between how ionic liquids dissolve, and how the boundary around the droplet fluctuates. Self-driven motion is a key feature of active matter, materials that use ambient energy to self-propel, with potential applications to drug delivery and nano-machine propulsion. Most people are familiar with how things mix…
