Date Jun. 28, 1990.A predictive coder, e.g., a hybrid DCT interframe predictive video decoder, reduces the tendency of long-term bias error in the decoded difference signal to accumulate in a predictor (7) by periodically alternating the polarity of the bias error relative to the contents of the predictor. Inverse discrete cosine transform (IDCT) stage (6) in a receiver is bracketed by switchable invertors (9a,9b) which, when operating, invert the signal into IDCT stage (6) and then reinvert the signal, plus error, out of IDCT stage (6), thereby inverting the error relative to the difference signal. Control means (10), e.g., a pseudo-random number generator, switches the invertors (9a,9b) in and out periodically such that, over several frames, each block spends an equal amount of time in "normal" and "inverted" modes.

Abstract: L'invention sert d''indicateur de réserve' pour les batteries, dont elle assure un contrôle continu dans toutes les situations, depuis une charge nulle jusqu'à la charge maximum, et en partie également pendant les opérations de charge. Du fait des dimensions du circuit électrique (2) et de la résistance de mesure du courant (7), le dispositif est réglé pour indiquer une réserve d'énergie minimum déterminée, dont la valeur est fixée entre 15 % et 35 % pour les batteries de véhicules à moteur. Si cette limite est atteinte à mesure qu'une batterie se décharge, le dispositif produit un signal qui persiste jusqu'à ce que la limite soit à nouveau dépassée vers le haut du fait que la batterie se charge. Dans ce but, les valeurs de tension et d'intensité de la batterie sont transmises à un circuit électronique sur lequel il apparaît, au niveau de l'entrée négative de l'amplificateur opérationnel (11), une valeur mesurée qui peut être comparée à la tension de référence au niveau de l'entrée positive. Lorsque la valeur mesurée devient inférieure à la tension de référence, la sortie de l'amplificateur opérationnel passe sur la butée positive et signale que la réserve d'énergie minimum déterminée a été atteinte. La baisse de tension de la batterie pendant la charge et une valeur déterminée par la baisse de tension de la résistance de mesure (7) se trouvent mutuellement dans le même rapport que la résistance (14) relativement à la résistance (15). L'action de la température sur la réserve d'énergie est mesurée au moyen de deux conducteurs chauffants (22, 23) couplés thermiquement à la batterie et elle est adaptée au moyen des résistances (16, 17, 24). Il est possible de fixer des valeurs de réserve d'énergie quelconques comprises entre 0 % et 100 %, d'établir les circuits correspondants conformément à l'invention et d'indiquer ces valeurs.

Granted: 1995-02-22
Abstract: 2.1 The object to be achieved in a pivot mounting is that the loading of the support lever is reduced in relation to known designs when said lever engages in the first catches of the base rail. The loading then results from the relatively small angle between the support lever and the base rail. 2.2 According to the invention, the width of the support lever (15) is greater than the height. Furthermore, the end of the support lever (15) facing the pivot lever (14) has a cylindrical continuation (19) which is mounted on the central web connecting the parallel limbs of the pivot lever (14). Furthermore, the spacing between two catches (18) of the base rail (13) is smaller in the direction towards the axis of rotation (24) of the pivot lever (14). The angle enclosed by the flanks of the catches (18) and the vertically enclosed angle is greater from catch to catch in the region facing away from the axis of rotation (24). The spacing between two catches is smaller in this region. 2.3 The pivot mounting according to the invention is suitable for beds, couches and similar furniture. <IMAGE>

Abstract: Very low viscosity polymer polyols having high styrene/acrylonitrile ratios and good stability may be achieved by the use of epoxy modified polyols as dispersants. The epoxy modified polyols useful as dispersants may be made by one of three methods: (1) adding the epoxy resin internally to the modified polyol, (2) capping or coupling a polyol not containing an epoxy resin with such a resin, and (3) providing the epoxy resin both internally to the polyol and as a cap or coupler. Epoxy modified polyols having a hydroxyl to epoxy ratio of about 6.8 or less, made by one of these techniques, are superior dispersants and provide polymer polyols having higher styrene contents, and improved stability and viscosity properties. In one aspect, the epoxy modified polyols contain a significant amount of high molecular weight polyol adducts; generally from about 5 to about 30 wt.% of materials having a GPC molecular weight of greater than 100,000; and at least greater than 80,000. Base polyols unmodified with an epoxy resin are used to make the polymer polyols.
