A magnetic field sensor for measuring a direction of a magnetic field in a plane comprises a sensing structure (4) comprising a ring-shaped well (10), a plurality of contacts (11) of equal size placed at equal distance from each other along the ring-shaped ...
The invention relates to novel polymer-based microstructures, with outstanding shape accuracy and cost-effective processing. The novel polymers are based on hyperbranched macromolecules and enable remarkable property combination such as reduced shrinkage a ...
Micro-electromechanical (MEM) laterally vibrating square resonators and beams, fabricated via a prototyping technology combining FIB-micromachined gaps with conventional UV lithography in 1.35 mu m thick SOI are presented. Resonators with both capacitive a ...

This thesis presents the results of a concerted effort to understand the complex array of physical properties exhibited by the BaVS3 family of materials. As a 3d1 system, BaVS3 displays a unique collection of correlation-driven phenomena, including a metal ...
Several works suggest the imminent appearance of bidirectional active devices. The promised performances go in the direction of a reverse recovery effects reduction and efficiency improvement. Our purpose is the study of an active management for switches t ...
The self-switching principle is a synthesis of synchronous type switching and switch inner protection mechanisms. Both switch ON and switch OFF are performed on the base of current and voltage measurement across the switch. Applied to an active bidirection ...
We present a new scalable architecture for the realization of fully programmable rank order filters (ROF). Capacitive Threshold Logic (CTL) gates are utilized for the implementation of the multi-input programmable majority (voting) functions required in th ...
This paper presents a family of three transformerless converters (buck, boost and buck-boost) with two specific characteristics: the quadratic static gain as a function of the duty cycle ratio, and the division of the higher voltage level between the two s ...
An `in situ' holographic technique, based on the use of a flexible miniaturized endoscope (diameter less than 1 mm) has been developed for medical applications. The holographic process provides quantitative information on the 3-D geometry of the observed s ...
The accessory e.g. lamp for illumination of the hand-held instrument (L) and the excitation coils (B1-B3) of the brushless motor (M) are all supplied with current through a rotary connector (F) from a control circuit (C1) within a fixed part of the machine ...
