Abstract: La présente invention veut renforcer les protocoles d'authentification en rendant plus difficile l'accès à des systèmes par des combinés contrefaits utilisant des attaques par réexécution. L'objectif visé est atteint au moyen de codes de contre-vérification servant de paramètres pour l'établissement de codes d'authentification, divers codes de contre-vérification générant divers codes d'authentification. Dans une application, les codes de contre-vérification sont fonctions du type de contre-vérification effectué (p. ex. contre-vérification globale ou unique) et/ou du mode d'utilisation (p. ex. appel de départ, réponse à un téléappel, enregistrement, repos et mise à jour des SSD-A). Cette application empêche les combinés contrefaits d'utiliser avec succès les attaques par réexécution pour se faire passer pour des combinés licites si ces derniers sont dans un mode différent de celui du combiné contrefait, ou si la demande d'accès légitime suscite une réponse de contre-vérification différente de celle du combiné contrefait.

Title: Alarm system using local data channel
Inventor: PARKER JAMES
IPC: G08B13/22
Filed: 1999-02-02
Abstract: The alarm system has an alarm unit for ready access at a point of entryway which communicates with a line seize module located in a secure location. The alarm unit has a transmitter receiver, a control panel function, a key pad, and an input/output port for connection to telephone wiring for communicating with the line seize unit. The line seize module includes its own input/output communication port connected to the wiring of the local telephone line and as such, is in direct communication with the alarm unit.      Communication is separate and distinct from normal telephone communication and preferrably is at a high frequency above the audible range. This allows the alarm system to communicate between components while still allowing full conventional use of the telephone lines. The line seize module also includes control logic, a line seize arrangement and an automatic dialer. When an alarm condition occurs, the alarm unit transmits a signal to the line seize module which then takes appropriate steps to contact the remote monitoring station via the telephone system. This two part alarm system which communicates over the existing telephone wiring, reduces the vulnerability of the system to defeat.

Abstract: L'invention concerne un moteur à combustion interne, qui comprend une unité de commande régulant différents composants, tels qu'un injecteur, une soupape d'échappement et une soupape de dérivation d'une pompe au moyen de signaux de commande numériques. Le moteur peut disposer d'un injecteur à entraînement hydraulique, qui envoie un certain volume de carburant dans une chambre de combustion interne. Le flux d'air pénétrant dans la chambre de combustion interne et le flux de gaz s'échappant de ladite chambre peuvent être régulés, respectivement, par une soupape d'admission à entraînement hydraulique sans came et par une soupape d'échappement à entraînement hydraulique sans came. L'actionnement hydraulique de l'injecteur et des soupapes est régulé par des soupapes de commande par fluide verrouillantes, qui sont actionnées par solénoïde. Le fonctionnement de l'injecteur et des soupapes est régulé par une unité de commande qui émet des signaux numériques pour actionner et verrouiller les soupapes de commande à solénoïde. Les signaux numériques consomment une énergie minimum et actionnent les soupapes à des vitesses relativement élevées. Le moteur comprend en outre une pompe, qui pompe le fluide hydraulique vers les soupapes de commande. Le système de pompage comprend une soupape de dérivation verrouillante, actionnée par solénoïde et à entraînement hydraulique, qui peut être ouverte pour coupler la sortie de la pompe à un tuyau de retour. Lorsque la soupape de dérivation est verrouillée en position ouverte, les substances s'échappant de la pompe sont déversées dans le tuyau de retour sans que la pompe ne fournisse un travail supplémentaire pour maintenir la soupape de dérivation en position ouverte. La soupape de dérivation peut être ouverte par un signal de commande numérique émis par l'unité de commande. L'unité de commande peut ouvrir et fermer la soupape de dérivation afin de réguler la pression de rampe communiquée aux soupapes de commande.

Patent CA-2268550-A1 (CA)
Inventor: PETTY NORMAN W
IPC: H04Q11/04
Filed: 1999-04-12
Abstract: An ATM cell constructor limits transmission-delay variations between successive cells of traffic of individual narrowband and wideband channels in a multi-channel environment. Whenever an ATM AAL1 layer of processing completes assembling an ATM cell payload for a narrowband channel, it increments a count that anticipates the number of ATM cells that will mature for transmission during the next cell construction period. For wideband channels, a function checks whether traffic from the number of narrowband channels that form the wideband channel will result in completion of assembly of that channel's cell payload during the next cell construction period; if so, the function increments the abovementioned count. The count is reset at the beginning of each cell construction period. Upon receipt of a command to add (start processing) a new channel, a TSI controller compares the count against a threshold that equals the total number of presently-active channels divided by the number of octets of traffic carried by each cell, plus one. If the threshold exceeds the count, the TSI controller sets up a TSI to start processing the new channel; otherwise the TSI controller delays setting up the TSI to process the new channel until occurrence of a cell construction period when the threshold exceeds the count. The net effect is to shift the delay variations from cells of active channels to the start-up of processing of new channels.
