There, systems are about to be controlled where human health or even human life is put at risk. For example, in automation systems first ideas surface to control parts of the system via a COTS smartphone. Another example is the idea to control the autonomous parking function of a car via a COTS smartphone too. As beneficial and convenient these ideas are on the first thought, on the second thought, dangers of these approaches become obvious. Especially in case of failures the system's safety has to be maintained. The open question is how to achieve this mandatory requirement with COTS components, e.g. smartphones that are not developed following the development process necessary for safetycritical systems. This paper presents a concept to reliably detect human interaction while activating safety critical functions via COTS mobile devices. Thus a means is provided to detect erroneous activation requests for the safetycritical function.}, language = {en} } @article{SchleglRobatzekKuceraetal., author = {Schlegl, Peter and Robatzek, Patrick and Kucera, Markus and Volbert, Klaus and Waas, Thomas}, title = {Performance analysis of mobile radio for automatic control in smart grids}, series = {International Journal of Advancements in Electronics and Electrical Engineering}, volume = {4}, journal = {International Journal of Advancements in Electronics and Electrical Engineering}, number = {1}, issn = {2319-7498}, pages = {69 -- 75}, abstract = {In the context of a "Smart Grid" research project, together with industrial partners, the OTH-Regensburg realized an intelligent medium-voltage grid in the local area. Goal was to improve the current voltage regulation and to counter the problems with inconsistent energy feed-in of decentralized renewable energy producers. In this paper we discuss the possibilities of using 3rd generation (3G) cellular networks (UMTS) as basic technology to communicate the voltage-levels within a medium-voltage grid. We build an experimental hardware setup to generate data-traffic as specified for the smart grid. By analyzing the performance of 3G cellular networks in terms of transmission latency and rate of failure, we tried to evaluate the usability of this technology for such critical data exchange. Though mobile communication in its structure is not specified for the use of transmitting such infrastructure critical data, the results show a promising high reliability with low transmission latency. The experiments served just to test a fragment of the conditions of use in a real scenario. An expanded test scope is needed to further analyze the performance of mobile radio for automatic control in smart grids. In the end the results discussed in this paper led to a successful prototype of an intelligent medium-voltage grid with mobile radio as communication technology}, language = {en} } @inproceedings{DegueldreWaasKucera, author = {Degueldre, Dennis and Waas, Thomas and Kucera, Markus}, title = {Electromagnetic Emission of an Optical-to-BroadR-Reach Converter}, series = {Proceedings of the 4th International Conference on Pervasive and Embedded Computing and Communication Systems (PECCS), 2014, Lisbon, Portugal}, booktitle = {Proceedings of the 4th International Conference on Pervasive and Embedded Computing and Communication Systems (PECCS), 2014, Lisbon, Portugal}, isbn = {978-989-758-000-0}, issn = {2184-2817}, doi = {10.5220/0004711401310135}, pages = {131 -- 135}, abstract = {The automotive solution for Ethernet is BroadR-Reach, which cannot be found as a common Ethernet-interface in the consumer industry. Hence a media converter from IEEE 802.3 Ethernet to BroadR-Reach is needed to debug and test the communication of automotive devices under test (DUT). If the functionality of a BroadR-Reach connection has to be tested for electromagnetic compatibility (EMC), a BroadR-Reach to optical media converter is needed, which has to comply to the same EMC test specifications as the DUT. This research explains the internal structure of a media converter and defines a test setup for copper bound emission test of BroadR-Reach. By using a standardized stripline measurement like it is common for electromagnetic emission test, it could be shown, that the tested Technica/Tinytron media converter can safely be used inside an EMC chamber.}, language = {en} } @inproceedings{ReinhardtKucera, author = {Reinhardt, Dominik and Kucera, Markus}, title = {Domain controlled architecture: A new approach for large scale software integrated automotive systems}, series = {PECCS 2013 - Proceedings of the 3rd International Conference on Pervasive Embedded Computing and Communication Systems, 19 - 21 February 2013, Barcelona, Spain}, booktitle = {PECCS 2013 - Proceedings of the 3rd International Conference on Pervasive Embedded Computing and Communication Systems, 19 - 21 February 2013, Barcelona, Spain}, publisher = {IEEE}, pages = {221 -- 226}, abstract = {Electric and electronic functionalities increase exponentially in every mobility domain.

To stand against rampantfunctionalities software units could be restructured according to their affiliation and should not be attached toa certain place. This can be effected by integration on single controllers. On the one hand the system wideamount of hardware controllers could such be limited. On the other hand the workload for integration CPUswill rise. To support this paradigm, multi-core systems can provide enough processing power in an efficientway.
