In this paper we propose to think out of the box and discuss an approach for universal mitigation of Negative Bias Temperature Instability (NBTI) induced aging untied from the limitations of its modelling. The cost-effective approach exploits a simple property of a randomized design, i.e., the equalized signal probability and switching activity at gate inputs. The techniques considered for structural design randomization involve both the hardware architecture and embedded software layers. Ultimately, the proposed approach aims at extending the reliable lifetime of nanoelectronic systems.

Electronic system Level (ESL) design flow tries to handle the complexity of today's system-on-Chip design and verification. Due to this complexity, design and verification methodologies start from an abstraction level higher than Register Transfer Level (RTL). In ESL, verification becomes a major bottleneck in the design flow, and finding a good verification methodology at this abstraction level is important. In this paper, we focus on communication parts of ESL designs rather than the computation parts. Here, we propose a new environment for ESL designs called RTL+, which is an abstraction level higher than RTL and yet lower than TLM-2 implementation of ESL. For RTL+ models verification, we propose using a simulation-based toolkit named C++TESK.

This paper aims to develop a sensor based monitoring and analyzing system for Neuro-Degenerative Disorder patients (NDD); this may consist on SpO2 sensor, Electrophysiological sensors, NIBP, Motion Capture sensors and Eye Monitoring sensor, taking into consideration an acceptable cost for the whole system. Recorded data will be sent to an embedded decision making unit where detection, analysis, classification, prediction and action control will occur. The sensors and the decision making unit will be implemented in a comfortable jacket that doesn't affect the patients' movements and that can be used by several patients with reduced sensor placement alterations. The decision that can be made is creating a stimulus to avoid falling in case of sudden stop while moving, initiating an alarm, sending a notification to a mobile phone application, and/or telemedicine monitoring features. Artificial Neural Networks will be used to classify and predict the abnormal cases where action should be taken, and since the sensors will be continuously recording, it is possible to achieve continuous learning for the ANN as a first phase. Initial models will be defined by testing normal behaviors and some known abnormal behaviors or symptoms related to the electrical activity and other characteristics of the heart, oxygen saturation level, eye activity and body motion.

An end-element, a logic solver system and a sensor are essential parts of safety-critical systems. The time to market of a brand new logic solver system might drastically increase when a safety-critical operating system needs to be written from scratch. According to our observations, the commercial safety-critical operating systems are not flexible enough to be reused for a brand-new platform. Consequently, we are going to present a generic safety-critical operating system. The operating system is written in an object-oriented programming language. Inheritance and polymorphism are used to achieve hardware independency. The first results show that more than thirty percent of source code might be reused. Thus, a lot of time for testing, documenting and certifying can be saved.

The software reliability plays an important role nowadays. From year to year the systems become more and more complex. Consequently, the software becomes more and more complex, too and this can cause more software errors. In this paper a new method is introduced, which serves to predict the reliability of software in a better way. Furthermore, the presumption that the hazard rate is constant is rebutted and a more realistic assumption is made. It is demonstrated that by the use of the new approach the prediction of the number of remaining errors is possible in a better way.

Autonomous guided vehicles have major benefits in terms of a rail bound conveyor technology because they are able to respond flexibly to changes in the application area. In many areas, safety-related position detection is necessary to avoid accidents. Derived from this position the driving speed in the work areas can be reduced in a safe way and minimum distances can also be observed in a safe manner. For this purpose, it is necessary to permanently control the measured position with regard to the disturbance variables and precision of measurements and in case of a deviation they have to be corrected in a highly reliable way. The solutions that are known so far do all imply two sensors that monitor each other. In the approach shown here, the required diagnostic coverage for a safety-related position determination is achieved through the use of only one laser scanner as well as through the help of algorithms that are implemented in a safety-related evaluation control. The focus of this paper is set on the position and orientation errors that are caused by measurement deviations.

Nowadays, many noticeable continues efforts are taken in the vehicle industry to develop robust intelligent systems that control and monitor the vehicles during operational time to lower the side effects of some abnormal conditions such as sliding and spinning; because of their main role in affecting the human safety and the vehicle life-time as well as the costs related to maintenance. Therefore, the importance of manipulating and controlling these special statuses with respect to safety and cost are the main motivations behind conducting this research work. In this paper a conceptual prototype of a safety-related platform for monitoring and recognizing the vehicles states by means of vibration sensors incorporated with incremental rotary encoders is presented. Additionally, the proposed approaches and algorithms to detect the vehicle status based on the captured sensory data are also presented.

Although the traditional task of communication protocols is the transmission of data, this is actually not completely sufficient if it is used in safety sectors. Therefore, it must be enhanced. In order to detect and overcome failures in systems, risk analysis and failure measurement must be taken into account in each safety-related system. This paper describes the advantages of having a safety-related system-on-chip with on-chip diagnostics in order to develop a safe transmission protocol. Here the concept of a CANopen Safety protocol stack on top of a safety-related system-on-chip that yields reliability to the complete product is presented.
