ELECTRONICS: The new DWS2103 digital scale display from HBM can be used to easily set up legal-for-trade scales which meet the new European measuring instruments directive (MID - Measuring Instruments Directive). The scale display works with analog and digital load cells. HBM offers FIT-type digital load cells and AED-type analog load cells and digital transducer electronics for this purpose. This makes both automatic and non-automatic weighing machines a possibility. The new scale display is particularly interesting for open systems that work with a PLC and standard field buses, as these can be expanded very easily and cost-effectively into a legal-for-trade solution.
The European measuring instruments directive has been included in national German law since 2007 with an amendment to the weights and measures act. The requirements in the area of weighing technology include in particular protection against manipulation in data transmission, for example from a load cell to the display unit. In the DWS2103 scale display, data transmission is implemented with the encryption process Advanced Encryption Standard (AES), which works with a 256 bit key. This modern encryption algorithm also meets the requirements of the WELMEC guideline 7.2. Manipulation during data trans-mission is thereby prevented so that the legal-for-trade capability of a scale is always ensured.
The digital signal transmission also offers the user numerous additional advantages. The data can for example also be transmitted wirelessly via a WLAN for instance. At the same time, electrical isolation is also provided. In addition, the DWS2103 scale display does not have to be installed in the direct vicinity of the actual scale. This digital technology also enables entry into modern Asset Management as, for example, information about the digital load cells can be automatically passed on to a super ordinate control system. In this way, condition-oriented early maintenance contributes to greater availability of the system.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
