Especially useful in onshore and offshore wind turbines SCHAUMBURG, IL--(Marketwired - November 03, 2016) - LEINE LINDE SYSTEMS is proud to announce the new ADSR®, the first diagnostic system for analyzing condition and predicting remaining service life within slip rings, especially useful in onshore and offshore wind turbines. This is a new smart solution for condition-based maintenance of slip rings. The centerpiece of the ADSR® are the integrated sensors for measuring vibrations, the level of voltage and current, number of revolutions, internal and external humidity, and temperature. This systematic monitoring and analysis enables the expected remaining service life of the slip ring to be displayed, both in terms of time and revolutions. Having this knowledge in advance makes it possible to use up the slip ring's entire service life. Unforeseeable failures will only rarely occur, and provides a positive impact towards the efficient operation of wind turbine power plants equipped with an ADSR®. It is important to note that on- and offshore wind turbines and wave & tidal energy plants are usually geographically distributed, and are therefore relatively far from service stations. Thus, unexpected servicing is incredibly involved and expensive. And pitch slip rings, which supply the rotor hub with voltage, signals, and data, are subject to wear due to their design. The ADSR's diagnostic system continuously monitors the contact systems and other key functions of the slip ring, enabling condition-based maintenance for optimized value added. The information and warning messages sent via the diagnostic system made available using network interfaces and are displayed by an LED on the slip ring. Maintenance personnel benefit from a browser-based web monitor that can be opened anywhere in the world to view the current status, as well as meaningful reports and analyses. The slip ring optionally communicates data to customizable interfaces using the OPC-UA industry standard -- an especially convenient feature. The ADSR® slip ring is customized to meet specific individual design requirements and supplied from one single source. LEINE LINDE SYSTEMS GmbH is headquartered in Hamburg, Germany, and is an independent company within the HEIDENHAIN Group. It offers a wide range of components and systems, which have already been deployed in wind energy applications for many years. Its products include heavy-duty rotary encoders for small and large, fast and slow shafts, and generator and pitch slip rings. What's more, the company offers its FSR, contactless rotary joints, pitch motors for individual pitch control, sensors for condensation, moisture, and temperature measurement, an ice prevention and monitoring system IPMS®, the elongation measurement system EMS, the PITCHMO® and YAWMO® sensors, prefabricated cables and switch cabinets.

Large public building complexes, such as exhibition halls, airports, shopping centers or museums, as well as hospitals and public authority buildings are sometimes like a maze. Arrows, maps and signs are supposed to make it clearer. But right when you enter the building for the first time, it is often very laborious and complicated to follow them through the maze of corridors, hallways, rooms and floors. Classic GPS-based navigation apps do not work in enclosed spaces, because the satellite signals are sometimes significantly disrupted by walls and ceilings. Researchers at the Fraunhofer Institute for Photonic Microsystems IPMS in Dresden, Germany have found a way to use smartphones for navigation inside buildings too. For this they rely on WLAN: With local radio networks, the researchers locate smartphones indoor to within about two meters. To determine the position, the software evaluates the signal strength of the WLAN spots. The app, which was originally developed for use in hospitals, is based on the Android mobile phone operating system. When starting the app, different targets can be selected – for example, examination rooms, patient rooms, cafeterias and restrooms or mobile inventory, such as beds and wheelchairs. As with navigation devices in cars, the user sees the building plan in a two-dimensional bird's-eye view. The target and current position are marked with dots and the shortest route is shown on the map. If the user moves, so does his position point. If the destination is outside the screen or on a different floor, arrows show the way. The hospital provides the material for the desired maps. Emergency evacuation plans can often be used as a template. "We can bring any large map sharply and without any annoying delays onto every screen," says Christian Scheibner from the Department of Wireless Microsystems of the IPMS. The app receives all the necessary data from the user's server. Thanks to open interfaces, the positioning and navigation algorithms as well as the graphical representations can be installed simply and straightforwardly in customers' applications. In the apps of trade fairs organizers, for example, which often lack maps, route planning or position determination. "Hospitals have caught up considerably in terms of wireless hot spots in recent years. For example, there are more and more medical devices which are equipped with WLAN and which can be used for indoor navigation" says the hardware and software developer Scheibner. The software works in all indoor areas where WLAN is available. The navigation destinations can be linked with other information. As a result, a user in a shopping mall, for example, will find his way directly and quickly to the rack with special deals. A demo system of the app is running successfully at the IPMS. "Interested parties can try it on site at the Institute at any time," says Scheibner. The technology was developed on behalf of an infrastructure outfitter for hospitals. They are being presented at the MEDICA international trade fair in Dusseldorf from November 16 to 19, 2015. Explore further: WLAN leads the way

(b-e) Cross sections that detail the NED elementary actuator cell. Credit: Fraunhofer Institute for Photonic Microsystems IPMS Researchers from the Mesoscopic Actuators and Systems (MESYS) project group at Fraunhofer Institute for Photonic Microsystems IPMS have been developing novel electrostatic microactuators, so-called nanoscopic electrostatic drives (NED), for three years. Now, this highly interesting scientific approach is being introduced to the public for the first time in an article appearing in the Nature Communications journal. Prof. Dr. Harald Schenk, Director of the Fraunhofer IPMS and Professor of Micro and Nanosystems at Brandenburg Technical University Cottbus-Senftenberg (BTU), is delighted, "We are very proud of the appreciation of our work and our results being published in this prestigious professional journal. After three years of basic research, we were able to demonstrate a completely new actuatory principle." The CMOS compatible actuator class technology developed by MESYS solves fundamental problems of electrostatic actuators. Previously, deflection was very limited due to the so-called pull-in-effects and the movement of conventional actuators was restricted to approximately 33 percent of the electrode spacing. This problem has now been solved. Group Leader Holger Conrad explains, "By means of suitable lever mechanisms, deflections which are much greater than the electrode separations are now available. Therefore, nanometer-small electrode spacings can be deployed, enabling actuators to make use of the enormous force of electrostatic fields." The patented actuator class can greatly improve the performance of microsystems such as capacitive ultrasonic transducers, tilting micro-mirrors and microvalves in the future. In addition, the actuator class provides completely new design solutions for microsystems such as micropumps, MEMS loud speakers or micro positioning systems. Conrad concludes, "Our vision is to develop electrostatic actuators with extremely small gap distances for high deflections at moderate control voltages. We want to extend the developed principle to enable in-plane movement and believe that the new electrostatic bender actuators could perspectively replace or supplement piezoelectric or electrostrictive materials as well. This would then allow for RoHs-compliant bender actuators."
