It is state-of-the-art that a Level 1 PSA also includes a fire PSA for all plant operational states. In performing Fire PSA not only the malfunction of the components has to be assessed but also all supply systems and cables have to be traced for a given component. In the past it was assumed in the case of a fire in a compartment that all components and cables in that compartment are not functional...
The plan to establish a European market for railway services and equipment requires technical regulations for interoperability. One topic to be regulated is the safety of railway operation under crosswind conditions. For this a method is necessary for categorising high-speed tracks with respect to their wind exposure. This method has to be simple and robust, and it has to be applicable to all European...
We present a novel network model for coplanar fed aperture-coupled patch antennas. The network consists of two ideal transformers, slotlines, microstrip lines with open stubs and a coplanar waveguide. This equivalent network model shows very good agreement with full wave analysis.
A novel low-cost transceiving mixer with excellent 1/f-noise properties for millimetre wave automotive radar systems at 76.5 GHz has been designed and fabricated. For good AM-noise suppression we use a single balanced mixer. We chose silicon Schottky diodes as non-linear elements to achieve the desired 1/f-noise behaviour. The nput signal with a power of 7 dBm serves as both as LO-signal of the mixer...
