Patent CA-2297961-C (CA)
Title: Dispositif de decollage pour aeronef
Inventor: STEFFEN SEPP
IPC: B64F1/06
Filed: 1999-05-06
Granted: 2005-11-08
Abstract: Le dispositif de décollage selon l'invention comprend un système télescopique (7), par exemple de trois tubes (4, 5, 6), qui est monté dans un cadre (3) de manière à pivoter de façon limitée autour d'un axe sensiblement vertical. Le cadre (3) est monté dans un axe horizontal (8) passant par le centre de gravité du dispositif et, de toute façon, par la ligne des centres de gravité de sustentation (2) de l'aile (1) de l'aéronef, et est pivotant autour de cet axe. Les forces agissant entre le système télescopique (7) et le cadre (3) sont transmises par l'intermédiaire d'un manchon (9) calé sur le tube extérieur (4). Un accumulateur de gaz comprimé est intégré, par exemple, au tube le plus intérieur (6) et peut être ouvert par un signal de pression de commande, ce qui a pour effet de sortir le système télescopique (7). Si le dispositif est monté sur un aéronef, la base du tube interne (6) heurte un point fixe du sol. L'aéronef peut ainsi être accéléré jusqu'à la vitesse de décollage. Après sa sortie, le système télescopique (7) est de nouveau rentré par l'intermédiaire du gaz comprimé stocké dans une enceinte sous pression (11). Le gaz comprimé s'échappant d'une soupape de sûreté principale est dévié vers l'arrière au travers d'un entonnoir (10).

Abstract: Apparatus and method for minimizing a retransmission of signals and messages when an errored message is received during an xDSL negotiation procedure of a communication session. A receiving section (52) monitors received data related to a Frame Check Sequence of an xDSL negotiation procedure. When the receiving section (52) determines that an errored message is received, a retransmission request device (54) transmits a retransmission request message. The retransmission request message indicates which correct message was lastly received. However, if a predetermined number of errored messages occur, the communication session is terminated.

Abstract: A separable loadbreak connector cuff venting tool having a handle formed of an electrical insulator material. An electrically insulating head is fixed on the handle's forward end. Two or more wedges, sized and shaped for slidable insertion within the cuff, are formed on the head. A rearwardly directed force applied along the handle's longitudinal axis gradually slides the wedges within the cuff, thereby venting partial vacua from within the cuff to the surrounding atmosphere and reducing the likelihood of flashover. Optionally, a clamp may be provided on a rearward portion of the handle for use in clamping the tool's handle to a hotstick handle. As another option, a pivot fulcrum may be provided on the rearward portion of the tool's handle for use in pivotally levering the tool's handle away from the hotstick handle. The tool's head, clamp and pivot fulcrum extend transversely away from the cuff venting tool, in the same direction.

Granted: 2009-11-24
Abstract: A packet network and method of operating the same is described. The network is arranged into a hierarchy, having one organisation-level portion (CS, P, R2) and three site-level portions (S1, S2, S3). By using forwarding computers and assigning multicast addresses in respect of each portion, the total number of multicast addresses required to send multicast messages to all possible subsets of potential recipients is reduced. This alleviates routers in the network of the burden associated with storing and processing a large amount of multicast addresses.

Abstract: A system for balancing communication traffic loading between adjacent base stations in a mobile communications network includes a mobile communications device having a communications subsystem, a processing device, a roaming software module, a storage device, and an RSSI adjustment sub-module. The communications subsystem is configured to receive signals from a current base station and one or more adjacent base stations. The processing device is coupled to the communications subsystem. The roaming software module executes on the processing device, and monitors a first signal strength and a current traffic indicator from the current base station and monitors a second signal strength from each adjacent base station. The storage device is coupled to the processing device and stores a recorded traffic indicator for the adjacent base station. The RSSI adjustment sub-module executes on the processing device, and calculates a first adjusted signal strength indicator as a function of both the first signal strength and the current traffic indicator and calculates a second adjusted signal strength indicator as a function of both the second signal strength and the recorded traffic indicator. The roaming software module compares the first adjusted signal strength indicator with the second adjusted signal strength indicator to control whether the mobile communications device roams from the current base station to the adjacent base station.

Abstract: A method and a wireless telecommunication system of performing network-assisted handover of calls between a serving network and another wireless network that employs communication protocols different from those of the serving network. A message is sent from a mobile station of a user to the serving wireless network, which includes an indication that the mobile station is capable of communicating with the neighboring wireless network. Information relating to the communication characteristics of the neighboring wireless network is also sent from the serving wireless network to the mobile station. Using the information relating to the communication characteristics of the neighboring wireless network, the mobile station receives radio signals from the neighboring wireless network. The quality of the radio signals between the mobile station and the neighboring wireless network is measured. The serving wireless network sends a message to the neighboring wireless network to request a handover of the communication transaction when the quality of the radio signals between the neighboring wireless network and the mobile station meets a predetermined minimum threshold. Then a handover of the communication transaction from the serving wireless network to the neighboring wireless network is executed after the neighboring wireless network has established a communication channel for the mobile station pursuant to the handover request.
