An innovative procedure has been developed to control induction heating of material used for semi-solid metal casting. By analyzing electrical value and permeability of the material the grain structure can be determined during the heating process. The induction heating can be regulated accordingly so that the material retains the optimal grain structure for forming.
The invention offers a method for generation of reproducible secret keys in products which were manufactured by means of lithographic production processes, such as chips.
The invention covers a new kind of monolithically integrated optical fibre coupling and its fabrication method.
At the University of Stuttgart (Germany) a new method and device were developed, which demodulates optical signals with 3 bit information per signal. At the same time the technical complexity of the receiver is reduced.
The new receive equalizer topology permits to reduce the equalizer chip area by a factor of 5 to 10 and to cut down power consumption by half compared to common equalizers.
Data rates far in excess of 10 Gbit/s can be achieved with the new structure.
Researchers at the University of Hohenheim are investigating membrane materials which at room temperature and at normal pressure exhibit a high diffusion coefficient for CO2 and at the same time retain methane securely. The selectively permeable materials could be used in e.g. innovative biogas containers to increase the energy content of biogas in a very simple and effective way.
