This paper introduces new functionalities for industrial safety applications using the wireless infrastructure of the IEEE 802.11 standard. The new amendments (n/ac/ad) for the 2.4, 5, and 60-GHz-band support additional high data rate modes, for e.g. video applications and device-to-device (D2D) communication. The huge bandwidth in the 60-GHz-band enables precise localization. However, Listen-Before-Talk...
This paper presents a technological solution for designing an assistive device for a biomechanical study of the Sit-to-Stand movement (STS). This device targets people with disabilities following a stroke. The control algorithms are implemented in TwinCAT runtime environment. The communication between all the component and the control computer is ensured via the EtherCAT fieldbus. The aim of this...
The challenges to deal with to design a WSN node which can be used in safety-relevant application are, to the present day, still to be completely investigated and solved. Nevertheless, a prototype implementation is presented in this paper, with an emphasis on the chosen hardware architecture and components, highlighting the limitations imposed by specific choices. Furthermore, an example application...
Complex safety-critical devices require dependable communication. Dependability includes confidentiality and integrity as much as safety. Encrypting gateways with demilitarized zones, Multiple Independent Levels of Security architectures and the infamous Air Gap are diverse integration patterns for safety-critical infrastructure. Though resource restricted embedded safety devices still lack simple,...
