Filed: 1995-06-08
Granted: 2003-04-08
Abstract: An apparatus for converting vibratory motion along a predetermined vibration axis to electrical energy comprises an enclosure having first and second opposite walls substantially parallel to one another. A magnet carrier structure in the enclosure also has first and second opposite walls substantially parallel to one another.  A pair of springs suspend the carrier structure in the enclosure so that corresponding first walls and corresponding second walls, respectively, face one another with a predetermined spacing therebetween.  The springs allow reciprocating movement of the carrier structure relative to the enclosure only along the vibration axis in response to the vibratory motion.  Separate magnet sets, each comprising a row of permanent magnets, are attached to a respective outer surface of the first and second walls of the carrier structure for producing a respective magnet flux. Separate coil assembly sets, substantially configured and dimensioned like the magnet rows, are attached to a respective inner surface of the first and second walls of the enclosure and are situated to be magnetically coupled to a corresponding one of the separate magnet sets in order to produce electrical current due to magnetic flux changes whenever the carrier structure and the enclosure move reciprocally with respect to one another along the vibration axis.

Abstract: A receiver for pseudorandom noise (PRN) encoded signals consisting of a sampling circuit, multiple carrier and code synchronizing circuits, and multiple digital correlators.  The sampling circuit provides digital samples of a received composite signal to each of the several receiver channel circuits. The synchronizing circuits are preferably non-coherent, in the sense that they track any phase shifts in the received signal and adjust the frequency and phase of a locally generated carrier reference signal accordingly, even in the presence of Doppler or ionospheric distortion. The multiple correlators in each channel correlate the digital samples with locally generated PRN codes having multiple offsets, to produce a plurality of correlation signals. The plurality of correlation signals are fed to a parameter estimator, from which the delay and phase parameters of the direct path signal, as well as any multipath signals, may be estimated, and from which a range measurement may be corrected.

Abstract: A tracking filter (10,80) which transitions from a type 2 loop to a type 1 loop as the loop error approaches 0 for fast settling and convergence without overshoot or ringing. The filter can either be implemented as an analog circuit (10) in hardware or digitally (80) is software. A first integrator (30) or first accumulator (82) is utilized to increment or decrement a discriminator (22,96) output error value as long as the sign of its output (32) from the previous iteration is the same as a sign of the error signal provided to its input (26) by the error discriminator (22,96). The first integrator output is limited to a range by a limiter (42) between a minimum and maximum value. If the sign of the first integrator output is different from the sign of the input, the contents of the first integrator or accumulator are dumped. The output from the first integrator or first accumulator has binary scaling (44,94) to scale its value before adding it to a second integrator (50) or second accumulator (88).

Abstract: Le procédé selon l'invention apporte une solution au problème de   la   régulation   thermique   individuelle   des   cuves d'électrolyse. Il consiste à agir sur la température de la cuve par l'intermédiaire de la résistance de consigne Ro, qui est modulée de manière à corriger la température à la fois par anticipation et par contre-réaction. D'une part, la correction par  anticipation,  dite  "a  priori",   tient  compte  des perturbations connues et quantifiées et permet d'en compenser par avance les effets sur la température de la cuve. D'autre part, la correction par contre-réaction, dite "a posteriori", consiste, à partir de la mesure directe et à intervalles de temps réguliers de la température du bain d'électrolyse, à déterminer une température moyenne corrigée en fonction des opérations périodiques d'exploitation, et à en compenser les variations  et les écarts par rapport à la température de consigne.  Les corrections sont eftectuées par l'ajustement régulier  d'une  valeur  dite  de  résistance  additionnelle, posifive ou négative, ajoutée à la résistance Ro de consigne de la cuve.
