Well-designed interactive visualizations help users gaining insights into an organization's data and, finally, making decisions. In the Business Intelligence (BI) context, the most popular visualization approach is dashboards, which combine multiple visual components, such as charts, on a single view. Well-founded decisions require the collaboration of several analysts, such as domain experts, line-of-business managers, or key suppliers. For face-to-face collaboration settings, multi-display environments and smart meeting rooms have improved. In the BI context, support for boardrooms is being discussed for this setting. In this paper, we propose annotation dashboards, based on a multitouch and multiuser interaction approach, which are integrated in a multi-display environment constituting a BI digital boardroom. In addition, means of semantic navigation help business users to easily get insights into business context information. © 2017 IEEE.

Energy consumption of electrical drive systems to be used in the intralogistics range had not been in the focus of engineering, since additional investments compared with energy savings of available units will not amortize in theory. The aim of this research project "Intelligent Drive and Control Technology for Energy-Efficient Intralogistics" is to find a solution for each drive-technological application used in an intralogistics system, e.g. a warehouse. In the future, this solution should be selected from a variety of technical solutions. It should be proved in advance, that this solution has the lowest energy consumption at fixed costs. To prove this, minimum 15 % electrical energy should be saved with the results of the innovation project in a reference logistics system under consideration that the life cycle costs remains constant compared with the initial situation.

This paper presents a bidirectional optical data transmission system as an enhancement of a contactless power transmission system (CPTS). The latter consists of two separate devices and is able to transmit up to 240W of electrical power using inductive resonant coupling. The optical system consists of two self-developed light-guiding structures and a short-reach free-space optical path. As source and sink of the optical system a light-emitting diode resp. a photodiode with a centroid wavelength of 850nm are used. The optical system is positioned within the CPTS; it transmits the PROFIBUS protocol. Due to the restrictions given by the applications areas of the CPTS, such as air gap up to 5 mm, misalignment up to 2 mm, tilting up to 5° and rotation angle up to 360°, different kinds of light-guiding structures are analyzed by simulation. Based on these results the most promising structures are selected and manufactured. Hereafter the attenuation and the near field characteristic of one light-guiding structure is analyzed. After this, the attenuation based on misalignment, variation of air gap, tilting and rotation between two light-guiding structures are analyzed by measurement. To check whether the requirements of the PROFIBUS has been satisfied by the complete data transmission system, the transient transmission behavior of the system was analyzed by a pseudo-random bit stream. In this paper the most important results of the design, the simulation and the measurement are explained. The presented results demonstrate the ability to design of such systems based on simulations and to evaluate the suitability of various geometries for present and future works. © 2017 SPIE.

The key to increasing the efficiency of bending processes lies in the use of Self-X-technologies. This is achieved by integration of Self-Xcomponents in purely mechanically driven tools and machinery to ensure continuous compliance of the required nominal values. The project "Self-X-Pro" within the leading-edge cluster "it's OWL" aims at the advancement of bending processes into intelligent engineering systems where self-correction is realized.

Weidmüller and Lanxess Deutschland have investigated the long-term hydrolysis resistance of connectors and test specimens made from unreinforced, flame-retardant polybutylene terepthalate (PBT) in natural as well as harsh climate. Component properties tested included the insulation resistance to DIN EN 60512 as well as the voltage and surge voltage resistance to IEC 60947-7-1. Prior to testing, the components were stored in normal and tropical climates, as well as in an accelerated test climate under super critical conditions and dry in a vacuum. The tests show that the electrical functionality of connectors and terminal blocks comply with the product specifications and are not compromised even after storage under extreme climatic conditions. Mechanical testing of the test specimens include impact strength and viscosity number as well as tensile and flexural strength. The impact strength exhibited the greatest sensitivity to the test climate of the mechanical properties observed.

Fulfilling all the requirements for reporting information about substances in products often seems to impose burdens that do not offer any value in return. The main question regarding product compliance (REACH, RoHS, industry-specific) is always how to get sufficient and up-to-date compliance information from your business partners. In this paper, we, company for electrotechnology Weidmüller and business software company SAP, present a new approach in which a business network facilitates collaboration with your business partners on product compliance information. The aim of this new approach is to increase the availability of the data and to bring compliance experts together. The main goal for the first release is to make it as easy as possible for suppliers to join the business network and to enable them to exchange regulation-driven product declarations. © 2012 Fraunhofer IZM.

Using DoE (Design of Experiments) methods, a parametric study of the effects of normal force, wear-velocity and wear path. on friction and electrical resistance behavior, was carried out. From the results, it was found that the contact force had little effect on the coefficient of friction, but it did, by contrast strongly affect the electrical contact resistance, as did an increased wear track. However it should be noted that these predictions may only be valid for the material pairs tested in this study.

Tin is one of the most widely used surface finishing materials for electrical connectors. In particular, for plug connectors where increasing demands are being made in terms of quality and reliability, the tribological properties of such coatings offer to both developers and manufacturers, an attractive option [1-3]. In addition to the nummerous parameters which define such systems such as current-carrying capacity, contact resistance, insertions and withdrawal force, the actual tribological properties, that ist, the coefficient of friction and wear data are too often neglected. The tribological properties of tin coating for plug connectors are today usually defined on an empirical basis, in terms such as lifetime (e. g. number of insertions). Wear of the actual contact surfaces is thus mostly descirbed in purely phenomenological terms such as coating removal by wear until the substrate is exposed or in terms of a failure to match a predetermined electrical specification.

The demand on innovative and state of the art products leads to the necessity to fullfill a broad variety of product requirements. This includes a construction which meets the demands of the market, a cost-effective production and a just in time market launch. Within this endeavour the main focus is on compelling quality and a resulting long product lifetime and reliability. The model derived from this study together with the respective lifetime tests and their statistical evaluation allows the deduction of fault rate, probability of failure and reliability for a newly designed contact pair for a pin and socket connector. The test scenarios are based on commonly known failure descriptions and taking into account the product application profile. The lifetime test duration can be reduced with known models respectively by accelerating methods according to Arrhenius, Hallberg - Peck and Coffin-Manson. The aim of this study is to obtain a deeper understanding of the correlation between the induced failure mechanisms and their occurrence within the used accelerated test method. Therefore this study includes a detailed surface analysis of the contact surfaces. The determination and characterisation of the occurring wear failure mechanisms can clearly identify the impact of the different climates and finally allows an assignment to well known climate specific failure mechanisms. © VDE Verlag Gmbh berlin offenbach.
