This paper investigates the possibilities to monitor the degree of disturbances of a wireless communication and to use this information to calculate online the necessary safety parameters in order to estimate the probability of failure per hour (PFH) and the safety integrity level (SIL). Depending of the degree of disturbances, addition actions are performed with the intention of keeping the current safety level. A hardware set-up is introduced to get process data and to evaluate the results. © 2020, North Atlantic university Union NAUN. All rights reserved.

Road accidents have been known to be one of the leading death causes around the world for a long time. Thus, cars and all kinds of road vehicles form a huge source of danger, and they relate to multiple high risks. There are many factors that can contribute to road traffic accidents such as the health condition of the driver if a medical emergency event happened while driving, drowsiness, or mind-wandering. The proposed system can monitor the behavior of the driver while driving as well as his/her health status. Moreover, it analyzes the monitored data, alerts the driver in a timely manner, and assists him/her in adjusting the driving behavior. Different dangerous and risky situations which can be faced during driving can be captured and avoided by using such a system which leads at the end to increase road traffic safety and reduce vehicle collisions. Notifications are developed in cases of drowsiness, loss of focus, or other concerns that may emerge while driving. However, when the driver's ability to operate the vehicle safely is hampered by a health concern, the implemented system is only able at this stage to alarm the driver itself and the surrounding cars as a first level of alarms. © 2023 IEEE.

Diagnostics is one of the significant parameters of functional safety which concerns itself with revealing dangerous incidents that might impede the operation of safety systems. Diagnostic coverage factor (DC) is defined as a metric for diagnostics in that DC is one of the most important design parameters to measure the effectiveness of safety protection systems. This study addresses how diagnostics impacts proof test interval (TI) when the system is halted completely;a thorough maintenance and changes in parts are performed. Besides this, the relationship between average probability of failure on demand (PFDavg), DC, TI and mean time to failure (MTTF) are presented for 1oo2 and 1oo2D system architectures. © 2014 IEEE.

We present novel concepts, technologies and potentials of optical data communication, especially for future computer architectures. The WDM (wavelength division multiplexing) and the optical wiring technologies are explained in detail. Experimental results of tunable optical filters, which play a major role in WDM systems, are reported. New concepts for novel optical interconnectors and novel miniaturized lasers for direct generation of green light are proposed as examples for possible next generation components to improve the performance of optical communication based computer architecture. © 2007 IEEE.

Nowadays the information of future rates of systems produced in series appears to be crucial to the production plan, especially for remanufacturing departments. Several questions need to be answered: the number of cores to remanufacture the condition of those cores as well as the number of replacement system the market requires. Based on a bivariate prognosis model, a multivariate model is developed to take more variables of stress in field into account. What's more, the fitting process has been optimized by using neural networks. This paper presents all necessary tools to perform a multivariate lifetime prognosis as well as the implementation in MATLAB. © 2019 European Safety and Reliability Association.

To remanufacture automobile systems, it is important to understand the future failure rate of the serially produced systems. In addition, remanufacturing departments need the information about the number of cores to remanufacture, the condition of these cores, as well as the number of replacement systems the market needs. Based on the existing univariate, bivariate and multivariate models a new improved forecasting model is developed, which considers practical factors like export of the vehicle to other countries, damage of the entire vehicle, reporting delay between production and in-market time or between vehicle failure and failure reporting time. This paper presents all necessary tools to achieve the improvement and its implementation in MATLAB. Copyright © 2019 European Safety and Reliability Association.

The details of future failures of systems that are serially produced are important for the remanufacturing departments to frame an optimal strategy for the post series supply. The existing one-dimensional and two-dimensional reliability prediction models predict field failures as a function of time based on the stress which the components/systems experience in the field until failure. In day-to-day situations the failure forecasts depend on many external factors like registration delay, which is the delay between the production of a system and its registration in market, reporting delay, which is the delay between the field failure and its reporting time, the export of vehicles to other countries or permanent damage caused to the vehicles. The improvement procedures are integrated into the existing reliability forecast models to reduce the incompleteness of the warranty data due to the influence of external factors using MATLAB. The verification process is to compare the forecasted field failures by the existing models with the actual field failures. The prognosis is carried out based on different failures data sets. With the help of sales data from Original Equipment Manufacturers, the forecasted failures Year to Date are verified. A validation of the results is carried out to check the impact of the influencing factors. © ESREL2020-PSAM15 *** by Research Publishing, Singapore.

The standard IEC/EN61508 provides the developer with guidelines to develop and implement safety related systems according to the international standard. The standard supplies qualitative and quantitative criteria to evaluate safety related systems, in order to apply it in safety critical applications. This paper details the criterion Probability of Failure on Demand (PFD). The authors derive the necessary equations and calculate the PFD-values for different system architectures. © 2007 Taylor & Francis Group.

The aim is reducing IEC 61508 certification effort for safety-related applications. Therefore, an object-oriented middleware has been implemented which, once being SIL3-certified, would allow transferring safety-related aspects from the application into an already-certified code layer. Safety-related applications using this middleware then could be written as straightforward as non-safety-related code. The SIL3 middleware is designed for an 8051-based microcontroller. Because of the 8-bit CPU architecture, several limitations have been encountered. These issues are explained in this paper, and solutions are proposed. The middleware will be used on the multi-more safety chip. SIL3 certified multi-core architecture for safety-related applications is described. Also, the SIL3 middleware architecture is given. The middleware is modular. Therefore, if the user does not want to use some modules they will not be included and code footprint will be smaller. In the SIL3 middleware numerous design patterns can be found. Patterns description and purpose are explained. The pseudo code for the singleton pattern is shown. Moreover, module implementation is depicted. The validation of the middleware is presented and the V-model for the middleware is provided. It conforms to the IEC 61508.

International Symposium on Fundamentals of Electrical Engineering (ISFEE)

作者： Karolin Löser Emil Delic Michael Schreiber Ali Hayek Josef Börcsök Institute for Computer Architecture and System Programming University of Kassel Kassel Germany

system-on-Chip architectures are increasingly designed for safety-related purposes. As a very high level of interlocking of hard- and software is required for such specialized systems, different concepts for the software composition are necessary. This paper investigates the benefits resulting from the utilization of a middleware which handles all low-level hardware access demanded by the application. Several measures recommended by standard IEC 61508 are implemented “quasi-automatically” if a certified middleware is used. In addition, the certification effort is drastically decreased if the implementation of main functionalities is based on certified, reused components. Another “side-effect” is the hiding of details concerning the system-on-chip and the operating system as the application always uses the middleware interfaces.
