    This paper describes a new method of desensitizing the gain of an inductive link to the mutual coupling of its inductors. When the coupling varies due to geometrical misalignments [1] this design method guarantees good efficiency and a large bandwidth. The mathematics for four link combinations are presented, and examples of the link efficiency and bandwidth for one of the combinations are shown a... View full abstract»

    Radio-frequency (RF) coils are used extensively in the design of implantable devices for transdermal power and data transmission. The practical issues of coil misalignments and configurations have not been investigated, and this paper presents a detailed theoretical analysis of misalignment effects in RF coil systems, including lateral and angular misalignments. Formulas are derived for the mutual... View full abstract»

    Scalp current density (SCD) makes possible the identification of scalp sources and sinks of current. SCD is reference independent and its peaks and troughs are sharper than those of the scalp potential (SP). SCD, by comparison to SP, reflects mainly the activity of cortical generators. SCD mapping appears to be a valuable tool to spatially split smeared SP distribution due to simultaneously active... View full abstract»

    This paper deals with source localization and strength estimation based on EEG and MEG data. It describes an estimation method (inverse procedure) which uses a four-spheres model of the head and a single current dipole. The dependency of the inverse solution on model parameters is investigated. It is found that sphere radii and conductivities influence especially the strength of the EEG equivalent...

    A set of van der Pol oscillators is arranged in a network in which each oscillator is coupled to each other oscillator. Through the selection of coupling coefficients, the network is made to appear as a ring and as a chain of coupled oscillators. Each oscillator is provided with amplitude, frequency, and offset parameters which have analytically indeterminable effects on the output waves. These sy... View full abstract»

    A preamplifier for physiological signals (ECG, EMG, etc.) is described for general use in mnltichannel applications. The limited number of components made it possible to implement eight channels on one Eurocard printed circuit board (160 x 100 mm) and 64 channels in a 9.5 in cabinet in a cost-effective manner (about $ 50 per channel). The use of a monolithic instrumentation amplifier based on the ... View full abstract»

    A digitally controlled analog phase shifter is described for the application in magnetic resonance (MR) imaging and spectroscopy. The design is based on a single side band modulator scheme. A phase resolution of 1.4°and a switching time of 400 ns are achieved. The device controls the phase of the intermediate frequency in the MR instrument, and hence can be used over the entire observe frequency ... View full abstract»
