Abstract: In order to control the threshold of a threshold decoder with a multilevel logic signal (for example a duobinary signal) liable to be corrupted by echoes, the value of the threshold of the decoder being programmable, the threshold of the decoder when echoes are present is adapted by relying on the measurement of the binary error rate. 
<??>Starting from a specified value (A) of the threshold, the corresponding binary error rate (P) is measured and, from this binary error rate, a value called the criterion (k1) is calculated (by adding a first fixed quantity to the value of the measured error rate, and by multiplying the whole by a second fixed quantiy), then the value of the threshold of the decoder is incremented step by step (B, C, D), and with each step the criterion is recalculated and updated if it has decreased, and on the first occasion (D) that the binary error rate becomes greater than the criterion the value of the threshold is stored and the procedure is continued by decrementing (C, B, A, E, F, G, H), and on the second occasion that the binary error rate (H) becomes greater than the criterion (k2), the half-sum of the two extreme values encountered (D, H) is chosen as threshold control value. 
<??>Application: cable distribution networks, for example for acting upon the duobinary part of a D2-MAC/PACKET signal.

Abstract: On aligne deux objets tels qu'un masque (8) et une plaquette (9) en utilisant une imagerie par polariseur à prismes croisés et des cibles sensibles à la polarisation (11, 15) pour améliorer le contraste du signal dans un alignement de proximité. Deux faisceaux de lumière polarisée de manière linéaire dont les axes de polarisation du champ électrique se situent au niveau des angles obliques l'un par rapport à l'autre, éclairent les repères du masque et de la plaquette et interagissent avec celles-ci. Les repères sont orientées de manière à induire une dépolarisation partielle de chaque éclairage incident au niveau de chaque plan, c'est-à-dire que les repères rendent visible une partie de la lumière lorsqu'elle traverse les filtres et un analyseur de polarisation (32, 34). Lorsque les repères sont visualisés par un analyseur de polarisation, la lumière parasite est rejetée et le contraste des repères est fortement amélioré.

Abstract: A rotor position estimator for a switched reluctance motor (SRM) employs a flux-current map to determine whether the actual rotor angle is closer to, or farther from, axial alignment of stator and rotor poles than a reference angle ϑ r . The flux-current map is a plot of reference flux Ψ r  as a function of current for the reference angle ϑ r . If a flux linkage estimate Ψ̂ i  is greater than the reference flux Ψ r , then the actual rotor angle is closer to alignment than the reference angle ϑ r , and the flux-map comparator output is a logic level one. If the flux linkage estimate Ψ̂ i  is lower than the reference flux Ψ r , then the actual rotor angle is farther from alignment than the reference angle ϑ r , and the flux-map comparator output is a logic level zero. When the result of the flux comparison causes the flux-current map comparator to change state, the actual rotor angle is equal to the reference angle ϑ r , with the result that phase currents can be successfully commutated relative to this rotor position. The flux-current map can be implemented using either single-phase or multi-phase SRM flux-current characteristics.
