A new solution for the integration of a wireless measurement system intended for the detection of hip prosthesis loosening by vibration analysis is presented. Small vibration amplitudes in the presence of noisy sensor signals of the excited prosthesi

The dynamics of a ring of three relaxation oscillators symmetrically coupled in the slow variable is considered both experimentally and by means of numerical simulations. It is shown that apart from the synchronous oscillation the basic set of period

We present a hardware realization of Kohonen's algorithm using many simple, linearly coupled active elements, namely a reaction-diffusion medium, that is a spatially extended active element. This medium also controls the learning-process. Both classi

An experimental setup for excitation and detection of hip prosthesis loosing is developed and analyzed. Small vibration signals are detected by acceleration sensors fixed in the prosthesis. Lock-in technique is applied to separate sensor signals at l

We present a new, all digital hardware concept for Kohonen self-organizing feature maps. The neurons of this implementation are rather simple computation nodes. Aside from a data bus they are interconnected with next neighbors only. This low connecti
