Patent CA-2232754-A1 (CA)
Title: Procede de controle de gain et recepteur associe
Inventor: TOMOE NAOHITO
IPC: H03G3/30
Filed: 1996-09-05
Abstract: En cas de signal non périodique émis par paquets à partir d'une station mobile en mode CAG avec une puissance de transmission non connue, le CAG est concentré sur une courte période au début du signal non périodique. En cas de signal périodique émis par paquets le contrôle de la puissance d'émission et la détection des ondes d'interférence se font en fonction de la présence ou de l'absence de signal vocal provenant de la station mobile. Ces processus préviennent les erreurs de contrôle du CAG et maintiennent la qualité du système de la station radio de base. En cas de signal non périodique émis par paquets, le signal reçu est détecté à grande vitesse du seul fait de la commutation d'un atténuateur à réponse à transitoires rapides et de la fixation du gain de l'amplificateur CAG à réponse à transitoires lents, ces deux éléments intervenant dans le contrôle du gain. En cas de signal périodique émis par paquets, les erreurs de contrôle du CAG sont prévenues et les interférences détectées en utilisant des mots synchrones contenus dans le signal émis par paquets.

Abstract: Procédé et système utilisés sur un réseau quasi-public, tel que le réseau internet, afin de permettre aux utilisateurs du réseau d'effectuer des transactions commerciales impliquant un paiement de fonds par un utilisateur à un autre utilisateur du réseau. Le procédé comprend l'utilisation d'un système informatique pour envoyer et recevoir des messages d'utilisateurs à travers le réseau. Lorsqu'un message est reçu à travers le réseau en provenance d'un utilisateur-vendeur qualifié, un message est envoyé par le réseau à l'utilisateur-acheteur qui a été identifié dans le message provenant de l'utilisateur-vendeur. Le message envoyé à l'utilisateur-acheteur demande une confirmation d'une transaction identifiée dans le message reçu de l'utilisateur-vendeur. Au moment de recevoir une confirmation par le réseau en provenance de l'utilisateur-acheteur, des informations concernant le paiement sont envoyées par des voies sûres hors réseau vers un agent de l'utilisateur-vendeur. L'agent de l'utilisateur-vendeur peut être une entité séparée, ou la fonction de l'agent de l'utilisateur-vendeur peut être assurée par le système de validation de la transaction. En recevant un code d'autorisation de la part de l'agent du vendeur, le code d'autorisation est chiffré puis envoyé à l'utilisateur-vendeur par le réseau.

Patent CA-2241510-A1 (CA)
Title: Specifiable delete times for voice messaging
Inventor: YAKER RHODA
IPC: H04M3/42
Filed: 1998-06-22
Abstract: A voice messaging system enables a callee to specify a retention time for retaining a stored voice message from a caller. The system then automatically deletes the stored voice message after the expiration of the retention time. In one embodiment, the caller is able to specify one retention time when the message is first recorded, and the callee can change that retention time when the message is retrieved. If the message is not retrieved by the callee before the caller-specified retention time expires, the system will automatically delete the message. In one embodiment, a callee can also assign a retention time to an outgoing voice message for playback to subsequent callers. The present invention improves the operations of a voice messaging system with limited memory resources, by reducing the chances that the system's memory will become filled with old messages which would leave the system unable to store new messages from callers.

Patent CA-2246294-A1 (CA)
Title: System and method for one-way spray/aerosol tip
Inventor: PY DANIEL
IPC: A61M11/00
Filed: 1998-09-01
Abstract: A nozzle mechanism for generating an aerosol-type liquid discharge is provided, which nozzle mechanism ensures one-way movement of liquid during discharge and also has a substantially zero "dead volume" at the tip of the nozzle. The nozzle mechanism includes a flexible nozzle portion with an outlet and a fluid channel, a rigid shaft received within the flexible nozzle portion, and a rigid housing surrounding the flexible nozzle portion and exposing the outlet. The rigid shaft interfaces the outlet to form a first normally--closed, one-way valve, as well as to define a swirling chamber for collecting the liquid which has been channeled from the liquid reservoir, prior to being discharged via the outlet. The outlet has a tubular wall with thickness that decreases along the elongated axis of symmetry for the outlet toward the tip of the outlet. The fluid channel is circumferentially positioned within the flexible nozzle portion to create swirling action of the liquid delivered to said swirling chamber. Once the pressure on the swirling liquid reaches a threshold pressure sufficient to radially deform the portion of the outlet forming the first normally--closed valve, the liquid in the swirling chamber is discharged through the outlet. The nozzle mechanism is coupled to a flexible body portion which has a substantially tubular shape and a wall thickness which decreases from the bottom of the body portion toward the flexible nozzle portion. The rigid shaft received within the flexible nozzle portions extends down into the flexible body portion so that a second portion of the rigid shaft interfaces the flexible body portion to form a second normally-closed, one--way valve in the fluid communication path between the liquid reservoir and the swirling chamber.

Filed: 1997-12-19
Abstract: Disclosed are an apparatus for keeping an optimal penetration depth formed at the front end of an oxygen tuyere in the producing facilities of molten pig iron utilizing non-coking coal and a method for keeping the same. A laser (2) as a sensor for measuring the penetration depth is provided, connected to a computer (3) for comparing the received signal with a predetermined optimal value. The pressure in a melter gasifier (11) is controlled dependent upon the penetration depth by changing the opening of a scrubber cone (4). The method can actively cope with the change. Thus the penetration depth can be optimally kept of the volumetric flow rate of the oxygen and the change of the oxygen flow rate and the constituting material in a coal packed bed and the applied pressure in the melter gasifier (11) to control the blowing velocity of the oxygen.
