Patent CA-2367228-C (CA)
Inventor: KEPLER MICHAEL A
IPC: H04W4/00
Filed: 1994-08-02
Granted: 2006-05-30
Abstract: A cellular telephone subscriber who wishes directory assist nce services is connected in the conventional manner to an operator who identifies a destination telephone number desired by the subscriber. As in the prior art, the operator then initiates a call connecting the subscriber to the destination telephone number. However, rather than dropping all further involvement with the call, the preferred embodiment of the present invention continually monitors the connection thereby established for a predetermined DTMF signal issued by the customer, such as that obtained by pressing the "*" button. If such a signal is detected, the customer is transferred back to a directory assistance operator, who can then provide whatever further assistance is needed (e.g. redialing a busy number, or providing further directory assistance). Billing information for the calls originated by the directory assistance operator on the subscriber's behalf is logged in a database at the directory assistance center. This data is thereafter provided to the cellular carrier, permitting it to bill the subscriber for calls originated by the directory assistance operator.

Abstract: In a steering device for a personal watercraft including a handle holder 42 fitted to a watercraft body 11, a steering shaft 41 passing through the handle holder 42, and a handle 43 fitted to the upper end of the steering shaft 41, the steering shaft 41 is provided with a groove 54, and a holding member 48 provided in the handle holder 42 is fitted into the groove 54, whereby movement of the steering shaft 41 in the axial direction is restricted. A flange or the groove has such a shape that its width can be reduced, and when the holding member is fitted by setting the width to be small and taking dimensional dispersions into account, the chattering between the flange or the groove and the holding member can be reduced. In view of this, the steering shaft is provided with the flange or the groove, and the holding member provided in the handle holder is fitted to the flange or the groove, so that movement of the steering shaft in the axial direction can be restrained. As a result, a steering device enhanced in operation feeling can be realized.

The network link information can include OSPF state information, OSPF configuration information, OSPF adjacencies information, OSPF interface information and OSPF global protocol information. Thereafter, any updates of network link protocol information are immediately forwarded to the standby processor (18). Upon failure of the active processor (12), the router (11) i s switched to the standby processor (18) and all OSPF protocol operations are performed on the standby processor (18). In the present invention, all state s of the link protocol immediately function as if a failure had not occurred.

IPC: B62D61/12

Granted: 2010-03-23
Abstract: The invention provides multi-axle running gear for automotive transport trucks and trailers, a minimum requirement being that the gear has two closely spaced parallel axles each carrying two spaced running wheels. One axle is mounted in a support housing for transverse movement along its longitudinal axis and will make such movement under scrubbing forces applied thereto by the wheels as the vehicle negotiates a curve or turn. The resultant slip steering axle provides a relatively simple structure equivalent to a self-steering axle, the slip steering movement reducing transverse scrubbing of the tires and yaw instability of the vehicle. The preferred extent of movement of the axle from its neutral position is equivalent to a steering angle of at least 20 degrees. Numerous applications are possible for multi-axle trucks and trailers, comprising such slip-steering axles in combination with one or more fixed, lifting and self-steering axles.

Abstract: The invention relates to a method for the removal of mercury from gas containing sulphur dioxide and oxygen and from the sulphuric acid vapour contained in the gas. According to the method, the gas is washed with a water solution that contains selenium ions, whereby metallic selenium is formed in the presence of oxygen, which precipitates the mercury in the gas and vapour either as a selenide or in a chlorine-containing environment, as a dichloride of mercury and selenium. Gas washing occurs at a low temperature, below 50 ~C.

Abstract: La présente invention concerne un système de détection basée sur le débit permettant de détecter des intrusions au sein de réseaux informatiques. On effectue un traitement de paquets de données représentatifs de communications entre utilisateurs dans un réseau de communications d'ordinateur à ordinateur et on les attribue à divers flux client/serveur. On recueille des statistiques pour chaque flux. Ensuite on effectue une analyse des statistiques des flux afin de déterminer si le flux semble constituer un trafic légitime ou une activité suspecte possible. On attribue une valeur-indice d'inquiétude à chaque flux qui présente un aspect suspect. Par l'attribution d'une valeur à chaque flux présentant un aspect suspect et par l'addition de cette valeur à la valeur-indice totale d'inquiétude, il est possible d'identifier les clients impliqués dans une activité d'intrusion. Lorsque la valeur-indice de référence d'un client dépasse une valeur d'avertissement prédéterminée, on délivre un avertissement et on peut prendre des mesures appropriées.
