Abstract: L'invention concerne un procédé permettant de réaliser des gains de type gros lot sur des bonus pendant une période de fonctionnement en mode bonus dans le cas d'un système (10) de machines (G) de jeu raccordées à un contrôleur (30).Les machines de jeu éligibles sont déterminées au début (TBM) de la période du mode bonus. Dès que cette période de mode bonus commence, une partie (S) des machines de jeu éligibles (E) est sélectionnée de façon aléatoire pour des opportunités (BO) de gains de bonus à gros lot multiples. Cette sélection aléatoire permet de déterminer la fréquence (R) selon laquelle les opportunités sont émises, ainsi que la durée moyenne de la période du mode bonus. Une fois que les machines de jeu sont sélectionnées, elles peuvent terminer la partie en cours, et au cas où cette partie se solderait par une combinaison gagnante, les gains de la partie sont alors multipliés par un multiplicateur (BM) de bonus. La machine de jeu asservie est responsable, de manière traditionnelle, de la remise des gains de la partie, et le contrôleur (30) autorise alors un gain de bonus à gros lot supplémentaire d'une valeur correspondant au gain de la partie multiplié par le multiplicateur (BM) de bonus moins un. La valeur du regroupement de bonus est alors diminuée du montant payé par le contrôleur. Ce processus se répète jusqu'à ce que les opportunités (BO) de multiplicateurs de mode bonus pour chaque multiplicateur (BM) de bonus à chaque tour (BR) de bonus soit terminées ou jusqu'à ce que la valeur du regroupement des bonus tombe au-dessous de zéro.

Abstract: The invention provides an amplifier circuit (600) for amplifying an input signal to generate an amplifier output signal. The circuit incorporates a cascaded series of reflection amplifiers (1400) arranged along a signal path and operative to amplify signals propagating in a forward direction along the signal path. The circuit is operative to counteract signal propagation in a reverse direction along the signal path, thereby hindering spontaneous oscillation from arising within the circuit (600). Incorporation of reflection amplifiers into the circuit enables it to provide high gain, for example 50 dB, whilst consuming low currents, for example tens of microamperes. The circuit (600) is especially suitable for use at intermediate frequencies in radio receivers such as mobile telephones.
