Abstract: It is a board game that may be played by two to eight people at one time.      The game is played on a board where there are six red obstacles to overcome. The obstacles consist of asteroids and a comet. A roll of the dice determines how many squares a player may proceed. When a player lands on one of the asteroids or the comet the player must go back to the start of the game. When a player rolls the dice and lands on a space with a spaceship on the landing strip the player proceeds to the next landing strip level.        A player who rolls the dice and manages to proceed past the asteroids and comet without running into an asteroid or the comet then goes past Neptune and heads for Pluto and deep space.   Near the finish line of the game there are four Black Holes. If a player rolls the dice and lands on one of the Black Holes he is eliminated from play. The first person who reaches the finish line without landing on one of the Black Holes is declared the winner of the game.

Title: Systeme numerique pour lignes d'abonnes permettant des debits binaires eleves
Inventor: FERTNER ANTONI
IPC: H04L5/02
Filed: 1998-06-30
Abstract: L'invention concerne une connexion de ligne d'abonné permettant des débits binaires élevés dans un réseau de télécommunication qui comprend une unité de ligne (5) connectée à un réseau de transport (1) et connectée au moyen de paires torsadées (7) à une unité d'abonné (9). Les informations sont transmises de manière bidirectionnelle sur les paires au moyen d'un multiplexage en fréquences à porteuses orthogonales. Les unités de ligne et d'abonné comprennent chacune des unités de modulation (19, 37) qui déterminent une transformée de Fourier discrète inverse sur des symboles entrants et des unités de démodulation (29, 43) qui permettent d'effectuer une transformée de Fourier discrète inverse sur un flux échantillonné du signal transmis sur les paires (7). Les unités de transformation (19, 29) utilisées pour la transmission dans un sens utilisent des porteuses différentes de celles qu'utilisent les unités de transformation (37, 43) dans le sens inverse. Les porteuses sont sélectionnées de manière qu'au moins une des propriétés spéciales des transformées soit utilisée pour réduire le nombre de calculs requis. En provenance de l'abonné (3), seules les porteuses présentant des repères impairs peuvent être utilisées dans l'unité de transformation (37). Ensuite, le signal de sortie envoyé sur les paires (7) va être constitué d'une séquence répétée dont la longueur est la moitié de celle obtenue lorsque les porteuses sont utilisées, de façon que seule une séquence dont la longueur est la moitié doive être calculée et répétée. Dans l'unité de transformation (43) recevant ce signal répété deux fois, les symboles reçus peuvent être divisés en deux segments égaux ajoutés l'un à l'autre. Ensuite, on peut effectuer une opération de transformation réduite. Dans le sens inverse, l'opération de transformation utilisant toutes les porteuses peut toujours être calculée. Les fréquences inférieures peuvent systématiquement être affectées au sens aboutissant à l'abonné, étant donné que la transmission à basse fréquence dans le sens inverse supporterait mal les bruits ou les interférences.

IPC: H04B7/005
Filed: 2000-04-19
Abstract: A power control system for a wireless communications system adjusts the transmit power of a wireless transmitter in relation to a number of acknowledgments expected for radio transmissions over a wireless link. For example, a wireless unit monitors the number of acknowledgments it receives (or fails to receive) for radio packets that the wireless unit transmitted over the wireless link. The wireless unit determines the number of acknowledgments lost in relation to the number of acknowledgments expected to be received by the wireless unit. The number of acknowledgments expected by the wireless unit can be based on the number of radio packets transmitted by the wireless unit. If the number of ACKs lost/ number of ACKs expected is greater than a first threshold, the wireless unit increases the transmit power level. If the number of ACKs lost/ the number of ACKs expected is below a second threshold, the wireless unit decreases the transmit power level.
