Abstract: Disclosed are coding and decoding methods and related coders and decoders, wherein signal components of plural channels are weighted-vector quantized as a single vector produced by combining them together with weights corresponding to their power components. The invention permits production of the quantization distortion through utilization of imbalance of power between signals of the channels without involving the adaptive bit allocation. Besides, by splitting a signal of one channel into a plurality of subchannels, power imbalance in the direction of the time axis is also effectively utilized to reduce the quantization distortion which permits implementation of high efficiency coding and decoding.

Abstract: WDMs have been used to separate a plurality of signals spatially by the difference of wavelengths in prior bidirectional multiwavelength optical communication network. For excluding WDMS, linear PD/LD modules adopt eigen-wavelength photodiodes sensing only the light of an eigen wavelength but allowing all the wavelengths longer than the eigen wavelength. An n-member PD/LD module aligns (n-1) eigen wavelength photodiodes, PD1, PD2, PD3, ···, PDn-1 of λ 1, λ 2, λ 3, ···, λ n-1 and an LD of λ n which satisfy inequalities λ 1 < λ 2< λ 3 < ··· < λ n in series on a beam line in the order of increasing the eigen wavelengths. Otherwise, an n-member PD/LED module aligns k eigen wavelength PDs of λ 1, λ 2, λ 3, ···, λ k and (n-k) LEDs emitting light of different wavelengths of λ k+1, λ k+2, λ k+3,··· λ n on the beam line in the same order. On the contrary, an n-member LD/PD module aligns a λ 1 laser and (n-1) eigen-wavelength photodiodes PD2, PD3,···, PDn of λ 2, λ 3,···, λ n in series on a beam line (λ 1< λ 2< λ 3<···< λ n). Otherwise, an n-member LED/PD module aligns k LEDs emitting light of different wavelengths of λ 1, λ 2, λ 3, ···, λ k and (n-k) eigen wavelength PDs of λ k+1, λ k+2, λ k+3, ··· λ n in series on a beam line( λ 1 < λ 2< λ 3< ··· < λ n).

Abstract: L'invention concerne un dispositif pour la lecture et/ou l'enregistrement d'informations depuis/vers une piste d'information sur un support d'information en forme de disque (1), qui comporte un système de balayage (2) permettant de balayer la piste d'information selon une vitesse linéaire, à une distance variable (r) d'un point de rotation du support d'information (1), et qui comporte aussi un système d'attaque (3) permettant d'engager la rotation du support d'information (1) selon une vitesse angulaire. Lorsque la distance (r) augmente, la vitesse angulaire du support d'information (1) décroît essentiellement et la vitesse de balayage linéaire s'accroît essentiellement (courbes de la zone 30 sur la figure). En conséquence, on bénéficie d'un temps d'accès court et d'un débit d'informations moyen élevé. Afin d'obtenir un temps d'accès minimum, on établit une relation entre la vitesse angulaire et la distance (r) de manière à ce que, dans le cas d'un déplacement rapide, la durée d'adaptation minimum nécessaire de la vitesse soit au plus aussi longue que la durée requise pour le déplacement rapide (courbe 33). La vitesse qu'il faut atteindre dépend des valeurs maximum et minimum du débit de lecture, d'enregistrement et de traitement de l'information.

Abstract: La présente invention concerne un procédé permettant de fragmenter des rochers et d'autres matériaux durs, comme le béton, en les faisant sauter en façon contrôlée avec une petite charge d'explosif. On introduit, au fond d'un trou curt (240) foré dans le roc, une cartouche (200) contenant une charge d'explosif. On donne à la charge une configuration telle qu'elle produise la pression désirée au fond du trou, y compris, si on le souhaite, une forte pointe d'onde de choc au fond, pour renforcer la production de microfractures. La cartouche (200) est maintenue en place ou bourrée avec un lourd bourroir, fait d'une matière très solide comme l'acier. La cartouche (200) comporte un volume intérieur supplémentaire, étudié pour réguler l'application de la pression dans le volume du trou du fond par l'explosif qui détone. Les principales caractéristiques du procédé et de l'appareil sont l'énergie relativement basse qui est imprimée aux débris de roc projetés et la quantité relativement faible d'explosif qui est nécessaire pour briser le roc.
